1. The ISO standard for energy management system is ____.
ISO 9001
ISO 50001
ISO 14000
ISO 14001
Answer: B) ISO 50001
Confirmed vs Book-1 §2 (EnMS — general) — ISO 50001 is the international standard for an Energy Management System (EnMS). ISO 9001 is quality management and ISO 14001/14000 is environmental management, which is why they are the tempting distractors. (The EnMS standard number is not printed in Book-1 Ch2; it is the standard BEE answer.)

📖 § Sec 14(h)/(i)/(l) — Energy Manager vs Accredited Energy Auditor
2. Which one of the following is not the duty of an energy manager under EC Act?
Report to BEE and state level designated agency once a year
Prepare an annual activity plan
Conduct energy audit
Prepare a scheme for efficient use of energy
Answer: C) Conduct energy audit
Confirmed vs Book-1 §2.3.6 — Sec 14(h)/(i) requires the energy audit to be got conducted by an ACCREDITED ENERGY AUDITOR — it is not the energy manager's job, so (c) is the odd one out. The energy manager designated under Sec 14(l) is in charge of activities for efficient use of energy: he plans the year's activities, prepares the scheme for efficient use of energy under Sec 14(o) and submits the annual status report on energy consumption to the designated agency.
3. Which industry among the following is not a designated consumer as per EC Act-2001?
fertilizers
chlor alkali
cement
nuclear power stations
Answer: D) nuclear power stations
Confirmed vs Book-1 §2.3.6 — The Schedule notifies nine energy-intensive industries as designated consumers: Thermal Power Stations, Fertilizer, Cement, Iron & Steel, Chlor-Alkali, Aluminium, Railways, Textile and Pulp & Paper. Nuclear power stations are NOT on that list — 'thermal power stations' (30,000 MTOE/yr) is the look-alike that makes (d) tempting.

📖 § 2.3.2 Standards and Labeling (S&L) — Star Ratings
4. Star rating is a ____ program of BEE
Demand Side Management
Integrated Energy Policy
Standards & Labelling
National Mission for enhanced energy efficiency
Answer: C) Standards & Labelling
Confirmed vs Book-1 §2.3.2 — Star rating is a ranking system (Star 1 = least efficient to Star 5 = most efficient) declared by the manufacturer and is part of BEE's Standards & Labelling programme, which puts energy labels on appliances. DSM manages the demand for power at the utility end and NMEEE is a NAPCC mission — neither issues star labels.
5. Which of the following sectors is not a designated consumer as per the Energy Conservation Act, 2001?
textile
paper and pulp
glass
chlor alkali
Answer: C) glass
Confirmed vs Book-1 §2.3.6 — Glass is not among the nine notified energy-intensive industries. Textile (3,000 MTOE/yr), Pulp & Paper (30,000) and Chlor-Alkali (12,000) are all notified designated-consumer sectors, so only 'glass' can be the answer.

📖 § Definitions — Energy audit
6. An energy audit as defined in the Energy Conservation Act 2001 does not include
action plan to reduce energy consumption
verification, monitoring and analysis of use of energy
submission of technical report with recommendations
implementation of all the recommendations of energy audit
Answer: D) implementation of all the recommendations of energy audit
Confirmed vs Book-1 §2.1 — The Act defines energy audit as 'the verification, monitoring and analysis of use of energy including submission of technical report containing recommendations for improving energy efficiency with cost benefit analysis and an action plan to reduce energy consumption'. Options (a)–(c) are all inside that definition; IMPLEMENTING the recommendations is the consumer's decision and is deliberately left outside it.

📖 § 2.3.3 Demand Side Management — peak/off-peak shifting
7. Statement not applicable to TOD (Time of the Day) in electricity tariff structure?
Higher energy charges during peak period
It is an incentive to maximize off- peak consumption
It is an incentive to minimize peak time power draw from the grid by consumers
It is a disincentive for Distribution Company
Answer: D) It is a disincentive for Distribution Company
Confirmed vs Book-1 §2.3.3 — A Time-of-Day tariff charges higher energy rates in the peak period, so it is an incentive for consumers to cut peak draw and to shift consumption to off-peak hours. That is precisely what the distribution utility wants under DSM (peak shaving, less costly peak power purchase), so calling TOD 'a disincentive for the Distribution Company' is the wrong statement.

📖 § 2.3.6 Designated Consumers — obligations
8. Which of the following statement is true regarding the EC act?
Designated consumers have to appoint Energy managers with prescribed qualifications.
State Designated Agencies have to appoint Energy auditor with prescribed qualifications.
Designated consumer has to get an energy audit conducted by a certified energy Manager.
Designated consumer has to get an energy audit conducted by the State Designated Agency
Answer: A) Designated consumers have to appoint Energy managers with prescribed qualifications.
Confirmed vs Book-1 §2.3.6 — The book states: 'Designated consumers have to appoint Energy managers with prescribed qualifications' and 'the designated consumer has to get an energy audit conducted by an accredited energy auditor'. Hence (c) and (d) are wrong — neither a certified energy manager nor the SDA may conduct the mandatory audit — and (b) is wrong because SDAs are not required to appoint auditors.

📖 § 2.3.6 Designated Consumers — obligations
9. Under the Energy Conservation Act, the designated consumer is required to get the mandatory energy audit conducted by
certified energy manager
certified energy auditor
accredited energy auditor
BEE
Answer: C) accredited energy auditor
Confirmed vs Book-1 §2.3.6 — The Act requires the DC's mandatory audit to be done by an ACCREDITED energy auditor — accreditation is granted by BEE under Sec 13(o)/(p) over and above certification. A certified energy manager or a merely certified energy auditor does not qualify, and BEE itself does not conduct audits.

📖 § 2.2 / Sec 15(d) — BEE at Centre, SDA in States
10. _____ in Centre and______ _ in States are mandated to implement the provisions of The Energy Conservation Act, 2001
BEE and NPC
BEE and DISCOM
BEE and SERC
BEE and SDA
Answer: D) BEE and SDA
Confirmed vs Book-1 §2.2 — BEE is the nodal implementing body at the Centre; within a State the Designated Agency (SDA), designated by the State Government under Sec 15(d), coordinates, regulates and enforces the Act. NPC, DISCOMs and SERCs have no implementing mandate under the EC Act — SERCs act under the Electricity Act 2003.

📖 § 2.3.1 Energy Conservation Building Codes (ECBC)
11. Energy Conservation Building Code (ECBC) sets;
Minimum Energy Efficiency Standards for design and Construction of Buildings
Green Building Rating System
Municipal DSM Regulations
Incentives for energy efficient buildings
Answer: A) Minimum Energy Efficiency Standards for design and Construction of Buildings
Confirmed vs Book-1 §2.3.1 — ECBC 'sets minimum energy efficiency standards for design and construction of commercial buildings' and defines norms of energy requirement per square metre by climatic region. It is a statutory code — not a voluntary green-building rating system, not a DSM regulation and not an incentive scheme.

📖 §11.1 Concept of New and Renewable Energy (cross-reference: Book-1 Ch.2 — EC Act 2001, BEE schemes)
12. Which of the following is one of the schemes of BEE under Energy Conservation Act ?
Standards and Labelling
Availability based Tariff
Standard of Performance of DISCOMs
Renewable Energy Certificates
Answer: A) Standards and Labelling
Confirmed vs Book-1 §11.1 Concept of New and Renewable Energy (cross-reference: Book-1 Ch.2 — EC Act 2001, BEE schemes) —
Standards & Labelling is one of the thrust-area schemes of BEE under the Energy Conservation Act, 2001.
Availability Based Tariff and DISCOM standards of performance are CERC/regulatory instruments and RECs come under the electricity/RE regulatory framework, not BEE schemes under the EC Act.

📖 § 2.3.6 PAT — sector-wise break-up of 478 DCs
13. Which one of the following is not a Designated Consumer category under PAT ?
Paper and Pulp Industries
Cement Plants
Chlor Alkali Plants
Sugar Plants
Answer: D) Sugar Plants
Confirmed vs Book-1 §2.3.6 — PAT's first cycle covered 478 designated consumers in eight sectors: Aluminium, Cement, Chlor-Alkali, Fertilizer, Iron & Steel, Pulp & Paper, Textile and Thermal Power. Sugar plants are not among them. (Note the related trap: Railways is a notified DC but is outside the PAT-8.)

📖 § Definitions — Building
14. A building intended to be used for commercial purpose will be required to follow Energy conservation building code under Energy Conservation Act, 2001 provided its
connected load is 120 kW and above
contract demand is 100 kVA and above
connected load is 100 kW and above or contract demand is 120 kVA and above
connected load is 500 kW and contract demand is 600 kVA
Answer: C) connected load is 100 kW and above or contract demand is 120 kVA and above
Confirmed vs Book-1 §2.1 — The Act defines a building as one 'having a connected load of 100 Kilowatt (kW) OR contract demand of 120 Kilo-volt Ampere (kVA) and above' used or intended for commercial purposes. Options (a) and (b) swap the two figures — 100 goes with kW and 120 with kVA — and (d) invents 500/600 values.

📖 § 2.3.6 DC thresholds / MTOE conversion
15. The unit used for determining a designated consumer is ___________.
million tonnes of oil equivalent per year
metric tonnes of oil equivalent per month
metric tonnes of oil equivalent per year
million tonnes of oil equivalent per month
Answer: C) metric tonnes of oil equivalent per year
Confirmed vs Book-1 §2.3.6 — Designated-consumer thresholds are notified in metric tonne of oil equivalent PER YEAR (Textile 3,000; Aluminium 7,500; Chlor-Alkali 12,000; the rest 30,000 MTOE/yr), with 1 MTOE = 1 x 10^7 kcal. 'Million tonnes' and 'per month' are the two distractor errors.

📖 § 2.3.6 DC thresholds / PAT sector break-up
16. Which of the following designated consumer has the lowest energy intensity?
Aluminium
Iron and Steel
Cement
Chlor alkali
Answer: A) Aluminium
Confirmed vs Book-1 §2.3.6 — The book's yardstick is the notified annual-consumption threshold: Aluminium 7,500 MTOE/yr is the lowest of the four options (Chlor-Alkali 12,000; Cement and Iron & Steel 30,000 each), and Aluminium also has the fewest DCs under PAT (10). So among the choices offered Aluminium is the intended answer.

📖 § 2.3.6 DC thresholds
17. Which of the following does not meet the Designated Consumer criteria?
Pulp and Paper Industries with minimum annual energy consumption of 30,000 TOE.
Cement Industries with minimum annual energy consumption of 30,000 TOE.
Chlor- Alkali Industries with minimum annual energy consumption of 7500 TOE.
Textile Industries with minimum annual energy consumption of 3000 TOE.
Answer: C) Chlor- Alkali Industries with minimum annual energy consumption of 7500 TOE.
Confirmed vs Book-1 §2.3.6 — Chlor-Alkali's notified threshold is 12,000 MTOE/yr, not 7,500 — 7,500 belongs to Aluminium, which is why (c) is the odd statement. The other three quote the book correctly: Pulp & Paper 30,000, Cement 30,000, Textile 3,000 MTOE/yr.

📖 § 2.3.6 DC obligations / Sec 14(l),(m)
18. As per Energy Conservation Act, 2001 appointment of BEE Certified Energy Manger is mandatory for
all State designated agencies
all large Industrial consumers
all designated consumers
all commercial buildings
Answer: C) all designated consumers
Confirmed vs Book-1 §2.3.6 — The obligation to designate or appoint an energy manager with prescribed qualifications attaches to DESIGNATED CONSUMERS (Sec 14(l) read with Sec 14(m)). Being merely large, being a commercial building or being an SDA does not by itself trigger the requirement.

📖 § Acts/Rules list — BEE (Manner and Intervals of Time for Conduct of Energy Audit) Regulations, 2010
19. Frequency of energy audit for designated consumers is______
once in a year
once in two years
once in three years
Once in five years
Answer: C) once in three years
Confirmed vs Book-1 §2.7 (Acts/Rules list) — The interval for a designated consumer's mandatory energy audit is fixed under the BEE (Manner and Intervals of Time for Conduct of Energy Audit) Regulations, 2010 — listed in the chapter's table of Acts, Rules and Regulations — and is once in three years. (The chapter lists the regulation but does not reprint the interval; three years is the notified value.)

📖 § 2.3.2 S&L — mandatory vs voluntary equipment
20. Which equipment does not come under mandatory labelling program?
Room Air conditioners
Frost free refrigerator
Induction motors
Distribution transformer
Answer: C) Induction motors
Confirmed vs Book-1 §2.3.2 — Only four items became mandatory under S&L from 7 January 2010: household frost-free refrigerators, room air conditioners, tubular fluorescent lamps and distribution transformers (up to 200 kVA). Induction motors appear in the VOLUNTARY labelling list, so they are the exception here.

📖 § Definitions — Energy audit
21. Which of the following is not a part of energy audit as per the Energy Conservation Act, 2001?
monitoring and analysis of energy use
verification of energy use
submission of technical report with recommendations
ensuring implementation of recommended measures followed by review
Answer: D) ensuring implementation of recommended measures followed by review
Confirmed vs Book-1 §2.1 — The statutory definition stops at verification, monitoring and analysis of energy use plus a technical report with recommendations, cost-benefit analysis and an action plan. Ensuring implementation of the measures and reviewing them is good practice but is outside the Act's definition, so (d) is not part of 'energy audit'.

📖 § 2.3.6 Designated Consumers — obligations
22. Which of the following criteria is a responsibility of Designated Consumer?
designate or appoint an accredited Energy Auditor
adhere to stipulated energy consumption norms and standards as notified
submit the status of energy consumption information every three years
conduct energy audit through a certified energy auditor periodically
Answer: B) adhere to stipulated energy consumption norms and standards as notified
Confirmed vs Book-1 §2.3.6 — The book lists as a DC obligation: 'Designated Consumers are required to adhere to energy efficient consumption norms stipulated.' The traps: (a) the DC appoints an ENERGY MANAGER (the auditor must be accredited, not appointed by the DC as its officer); (c) the status of energy consumption is submitted EVERY FINANCIAL YEAR, not every three years; (d) the audit must be by an ACCREDITED, not merely certified, energy auditor.

📖 § 2.3.6 DC obligations / Sec 14(l)
23. As per Energy Conservation Act, 2001, a BEE Certified Energy Manger is required to be appointed/designated by the
state designated agencies
all industrial consumers
designated consumers
electrical distribution licensees
Answer: C) designated consumers
Confirmed vs Book-1 §2.3.6 — Sec 14(l) empowers the Central Government to direct any DESIGNATED CONSUMER to designate or appoint an energy manager in charge of efficient use of energy. State designated agencies, all industrial consumers and distribution licensees are not covered by that requirement.
Source: 2017
📖 § 2.3.6 DC obligations
24. The Energy Conservation Act,2001 requires that all designated consumers should get energy audits conducted periodically by
certified energy manager
certified energy auditor
accredited energy auditor
state Designated Agencies
Answer: C) accredited energy auditor
Confirmed vs Book-1 §2.3.6 — 'The designated consumer has to get an energy audit conducted by an accredited energy auditor.' Accreditation (BEE's list under Sec 13(o)) is the key word; a certified energy manager or a certified energy auditor without accreditation cannot sign the mandatory audit, and SDAs only compile the reports.

📖 § 2.3.6 PAT — empanelment criteria for verification/check-verification
25. Verification and Check-verification under PAT will be carried out by
Designated consumers
Accredited energy auditors
Certified energy auditor
Empanelled accredited energy auditors
Answer: D) Empanelled accredited energy auditors
Confirmed vs Book-1 §2.3.6 — The chapter gives 'Empanelment Criteria of Accredited Energy Auditor's Firm for Verification and Check-Verification under PAT Scheme' (at least one accredited energy auditor, at least three energy auditors, ₹10 lakh turnover/net worth). So the work is done by EMPANELLED accredited energy auditors — mere accreditation without empanelment is not enough.

📖 § 2.3.6 PAT — Energy Savings Certificates
26. One energy saving certificate ( ESCerts) under PAT is equivalent to
one ton of carbon
one MWh of electricity
one ton of coal
one ton of Oil equivalent
Answer: D) one ton of Oil equivalent
Confirmed vs Book-1 §2.3.6 — ESCerts are denominated in energy, not carbon: one ESCert equals one metric tonne of oil equivalent (1 MTOE = 1 x 10^7 kcal) of energy saved beyond the notified SEC target. A tonne of carbon is a CDM/CER unit and MWh/tonne of coal are not the PAT unit of account.

📖 § Investment appraisal (general — developed in Book-1 Ch5)
27. To judge the attractiveness of any investment, the energy auditor must consider
Initial capital cost
Net operating cash inflows
salvage value
all the above
Answer: D) all the above
Confirmed vs Book-1 §2 (general) — An investment's attractiveness depends on the initial capital cost, the net operating cash inflows it generates over its life and the salvage value at the end — all three enter the payback / NPV / IRR calculation, so 'all the above' is correct. Picking any single item ignores the other two cash flows.

📖 § 2.3.6 PAT — ESCerts tradable at Power Exchanges
28. ESCerts cannot be ____.
Bought
Sold
Banked for next cycle
Traded directly between DC's
Answer: D) Traded directly between DC's
Confirmed vs Book-1 §2.3.6 — The book says ESCerts issued for excess savings 'will be tradable at Power Exchanges' and that units gaining ESCerts may bank them for the next PAT cycle — so they can be bought, sold and banked. What they cannot be is traded directly between designated consumers outside the exchange platform.

📖 Book-1 §2.5 Integrated Energy Policy (Ch-2); linked to Ch-6 energy policy
29. Which issue is not addressed by Integrated Energy Policy of India?
consistency in pricing of energy
scope for improving supply of energy from varied sources
energy conservation, research and development
removal of subsidies for energy across all sectors
Answer: D) removal of subsidies for energy across all sectors
Confirmed vs Book-1 Book-1 §2.5 Integrated Energy Policy (Ch-2) — The Integrated Energy Policy (Expert Committee, Planning Commission, Aug 2006) was framed precisely because consistency in pricing of different types of energy was lacking, and to give direction on energy security (supply from varied sources) and on energy conservation and R&D - so (a), (b) and (c) ARE addressed. Blanket removal of subsidies across all sectors is not a feature of the policy; it seeks targeted, transparent subsidy and market-based pricing instead.

📖 § 2.3.4 Bachat Lamp Yojana (BLY) — 60 W incandescent replaced by 11–15 W CFL
30. A power utility distributed 1 million 15 Watt CFLs for Rs 15 million, replacing 60 Watt incandescent lamps under Bachat Lamp Yojana. What will be the drop in power in the evening on the demand side, if 80% of the lights are on at that time, assuming similar numbers of incandescent lamps were switched on during the same period?
360 kW
12 MW
36 MW
60 MW
Answer: C) 36 MW
Corrected (was a) — Book-1 §2.3.4: Saving per lamp = 60 W − 15 W = 45 W. With 1 million lamps and 80% of them burning in the evening, the demand drop = 0.8 × 10⁶ × 45 W = 36 × 10⁶ W = 36 MW. Option (d) 60 MW wrongly takes the whole 60 W incandescent load instead of the 45 W saving, and (a)/(b) drop the 80% diversity factor or a decade in the arithmetic. The stem and option (a) were garbled in the source (the tail of the question had been merged into option a).

📖 § Definitions — Energy audit
31. Which is not a part of “ Energy Audit” defined as per the Energy Conservation Act, 2001
monitoring and analysis of energy use
ensuring implementations of recommended measures followed by review
submission of technical report with recommendations
verification of energy use
Answer: B) ensuring implementations of recommended measures followed by review
Confirmed vs Book-1 §2.1 — Energy audit under the Act = verification, monitoring and analysis of energy use + technical report with recommendations, cost-benefit analysis and action plan. Options (a), (c) and (d) are all named in that definition; 'ensuring implementation of recommended measures followed by review' is not, so it is the exception.

32. The legal framework for energy efficiency in India is given by
Electricity Act 2003
Energy Conservation Act 2001
Electricity (supply) Act 1958
Indian Electricity Act 1910
Answer: B) Energy Conservation Act 2001
Confirmed vs Book-1 §2.2 — The Energy Conservation Act, 2001 (Act 52 of 2001, dt 29-9-2001) is the legal framework for energy efficiency in India and created BEE plus the State Designated Agencies. The Electricity Act 2003 restructures the electricity sector (generation, transmission, distribution, trading) and the 1910/1948 Acts it consolidated dealt with electricity supply — none of them is the energy-efficiency law.

33. The first amendment to the Energy Conservation Act was made in
1948
2003
2007
2010
Answer: D) 2010
Confirmed vs Book-1 §2.7 (Acts/Rules list) — The chapter's table of Acts records: 'THE ENERGY CONSERVATION ACT, 2001 [Act 52 of 2001, dt 29-9-2001] [As amended by Act No. 28 of 2010, dt 4-8-2010]' — so the first amendment is 2010, the amendment that brought in PAT, ESCerts and Sec 14A/14B. 2007 (ECBC launch) and 2003 (Electricity Act) are the tempting year-traps.

📖 § Book EOC Q3 / 2.2 — BEE as nodal agency
34. The nodal agency at the centre for implementing the EC act is
CEA
SDA
BEE
Ministry of Power
Answer: C) BEE
Confirmed vs Book-1 §2.2 — BEE, set up under the EC Act under the Ministry of Power, is the nodal agency at the Centre; the SDA plays that role within a State. CEA is the technical adviser under the Electricity Act 2003 and the Ministry of Power is the parent ministry, not the implementing agency.

📖 § Book EOC Q4 / Definitions — Building
35. The minimum connected load for a building as defined in the amended EC act is
100 kW
100 kVA
500 kW
500 kVA
Answer: A) 100 kW
Confirmed vs Book-1 §2.1 — The definition of 'building' fixes the minimum CONNECTED LOAD at 100 kW (the alternative trigger being a contract demand of 120 kVA and above) for premises used or intended for commercial purposes. Connected load is stated in kW, so 100 kVA is a unit trap and 500 kW/kVA are simply not in the Act.
Source: Guidebook
📖 § Book EOC Q5 / Definitions — Energy audit
36. As per EC act, the definition of energy audit does not consider
monitoring
verification
analysis
duration of audit
Answer: D) duration of audit
Confirmed vs Book-1 §2.1 — The Act's definition of energy audit expressly names verification, monitoring and analysis of use of energy, together with the technical report, cost-benefit analysis and action plan. It says nothing about how long the audit must take, so 'duration of audit' is the item not considered.

📖 § Book EOC Q6 / 2.3.2 Standards and Labeling
37. Star rating is a part of which programme of BEE
DSM
BLY
S&L
none of the above
Answer: C) S&L
Confirmed vs Book-1 §2.3.2 — Star rating (Star 1 = least efficient to Star 5 = most efficient, declared by the manufacturer) is part of the Standards & Labelling programme, under which energy labels are affixed to appliances. DSM manages the utility's demand and BLY was the CFL replacement scheme — neither awards stars.

📖 § Book EOC Q7 / 2.3.6 — Energy conversion values for MTOE
38. For the purpose of calculating MTOE for a designated consumer the calorific value of oil is taken as
10,500 kcal/kg
10,000 kcal/kg
10,400 kcal/kg
9,800 kcal/kg
Answer: B) 10,000 kcal/kg
Confirmed vs Book-1 §2.3.6 — The chapter's conversion table states '1 kg of Oil Equivalent = 10,000 kcal' and hence '1 MTOE = 1 x 10^7 kcal', which is the basis for computing a designated consumer's annual MTOE. 10,500 kcal/kg is the GCV of HSD used in the solved example — the classic trap here.

📖 § Book EOC Q8 / Definitions + 2.3.1 ECBC
39. The norms for energy consumption in ECBC is defined as energy consumption per
day
hour
square foot
square meter
Answer: D) square meter
Confirmed vs Book-1 §2.3.1 — ECBC 'means the norms and standards of energy consumption expressed in terms of per square meter of the area' wherein energy is used, and includes the location of the building. The unit is therefore per SQUARE METRE — square foot is the unit trap and day/hour are not area norms.

📖 § Book EOC Q9 / 2.3.3 Demand Side Management
40. DSM is of benefit to
Government
DISCOM
user
all of the above
Answer: D) all of the above
Confirmed vs Book-1 §2.3.3 — DSM shifts demand from peak to off-peak, so the DISCOM avoids buying expensive peak power and defers capacity addition; the user manages his load curve and cost better; and for the Government the saved MW count like new supply-side additions, cutting capital needs for capacity expansion. Hence all three benefit.

📖 § Book EOC Q10 / 2.3.4 Bachat Lamp Yojana
41. The major portion of subsidy under BLY is met by revenues from
electricity boards
CDM
DISCOMS
central budget
Answer: B) CDM
Confirmed vs Book-1 §2.3.4 — BLY sells CFLs to households at about ₹15, the price of an incandescent bulb, and 'plans to use the Clean Development Mechanism (CDM) to recover the cost difference between the market price of the CFLs and the price at which they are sold'. DISCOMs and CFL suppliers are PPP partners but do not fund the gap, and there is no central-budget subsidy in the scheme.
42. Which of the following industry/sector is not notified as a designated consumer as per EC Act-2001?
Pulp & Paper
Automobile
Chlor-Alkali
Fertilizer
Answer: B) Automobile
Confirmed vs Book-1 §2.3.6 — The nine notified energy-intensive industries are Thermal Power, Fertilizer, Cement, Iron & Steel, Chlor-Alkali, Aluminium, Railways, Textile and Pulp & Paper. Automobile manufacturing is not notified, while Pulp & Paper, Chlor-Alkali and Fertilizer all are.

43. The nodal agency for implementing Energy Conservation Act in India is ____.
Bureau of Electrical Efficiency
National Productivity Council
Central Electricity Authority
Bureau of Energy Efficiency
Answer: D) Bureau of Energy Efficiency
Confirmed vs Book-1 §2.2 — The Bureau of Energy Efficiency, created under the EC Act 2001 under the Ministry of Power, is the nodal implementing agency (with SDAs in the States). 'Bureau of Electrical Efficiency' does not exist, NPC is a productivity/consultancy body and CEA is the technical adviser under the Electricity Act 2003.

44. Under the Standard's and Labeling (S&L) Scheme of the BEE,
Building codes are prescribed for commercial buildings
Industries are required to meet specific energy targets
Energy Star labels are affixed on appliances
LED Lamps are distributed
Answer: C) Energy Star labels are affixed on appliances
Confirmed vs Book-1 §2.3.2 — Under S&L, energy-efficiency (star) labels are affixed to appliances so that the consumer gets an informed choice about energy and cost savings. Building codes are ECBC, specific energy-consumption targets for industry are PAT, and lamp distribution was BLY — all different schemes of BEE.

📖 § 2.3.1 ECBC — EPI (detail in Book-3 Ch10)
47. As per ECBC, EPI calculation includes ____.
Solar photovoltaic Energy
Grid energy purchased
captive DG power
b and c
Answer: D) b and c
Confirmed vs Book-1 §2.3.1 — The Energy Performance Index counts the energy actually delivered to and consumed in the building per square metre per year — grid electricity purchased plus captive DG generation. On-site solar PV generation is excluded from the EPI numerator, so the answer is 'b and c'. (Ch2 refers the ECBC detail to Book-3, Chapter 10.)

48. The nodal agency at centre for implementing the Energy Conservation Act in India, is ____.
Central Electricity Authority
Central Electricity Regulatory Commission
Bureau of Energy Efficiency
National Productivity Council
Answer: C) Bureau of Energy Efficiency
Confirmed vs Book-1 §2.2 — BEE is the central nodal agency for implementing the EC Act 2001, with State Designated Agencies enforcing it in the States. CEA (technical adviser) and CERC (tariff regulator) act under the Electricity Act 2003, and NPC is only a training/consultancy organisation.

49. As per Energy Conservation Act, 2001 appointment of BEE Certified Energy Manager is mandatory for ____.
All commercial buildings
All State designated agencies
All large Industrial consumers
All designated consumers
Answer: D) All designated consumers
Confirmed vs Book-1 §2.3.6 — The Act's requirement to designate or appoint a certified energy manager applies to DESIGNATED CONSUMERS — the notified energy-intensive industries in the Schedule. Commercial buildings, all 'large' industrial consumers and SDAs are not, as such, under that obligation.

📖 § 2.3.2 S&L — objectives
50. The objectives of Standards & Labeling (S&L) programme aim to:
Set sulphur standards for coal-fired power plants
Provide informed choice about energy saving
Enforce penalties on renewable obligation non-compliance
Fix tariff slabs for power-intensive industries
Answer: B) Provide informed choice about energy saving
Confirmed vs Book-1 §2.3.2 — The stated objective of S&L is 'to provide the consumer an informed choice about the energy saving and thereby the cost saving potential of the marketed household and other equipment'. Sulphur norms are pollution control, RPO enforcement is under the Electricity Act 2003 and tariff slabs are set by regulatory commissions — none is an S&L objective.

📖 § Definitions — Designated Consumer
51. 'Designated Consumers' under EC Act are classified mainly because:
They are exempted from energy audits
They focus only on renewable generation
They represent small artisan industries
They are users of energy in an energy intensive industry
Answer: D) They are users of energy in an energy intensive industry
Confirmed vs Book-1 §2.1 — 'Designated consumer means any user or class of users of energy in an energy intensive industry and other establishments specified in the Schedule as designated consumer.' They are therefore large energy users who must appoint energy managers, get accredited audits done and meet norms — not exempted, not small artisan units and not renewable-only entities.

📖 § Chapter IV — Sec 13, Powers and Functions of the Bureau
52. What is the mission of the Bureau of Energy Efficiency (BEE) under the Energy Conservation Act 2001?
To regulate electricity tariffs at the national level
To promote renewable energy by providing capital subsidies
To develop policies and strategies that reduce the energy intensity of the Indian economy
To license only energy auditors and energy managers
Answer: C) To develop policies and strategies that reduce the energy intensity of the Indian economy
Confirmed vs Book-1 §2.3 (Sec 13) — BEE's mandate under Sec 13 is to develop policies, strategies, standards, codes and capacity that reduce the energy intensity of the Indian economy — recommending norms and labels, notifying DCs, ECBC guidelines, awareness, training and certification. Electricity tariff regulation belongs to CERC/SERCs and renewable capital subsidy to MNRE, and certification is only one of BEE's many functions, not its whole mission.

📖 § 2.3.1 Energy Conservation Building Codes (ECBC)
53. What is the main purpose of the Energy Conservation Building Code (ECBC)?
To set minimum energy efficiency standards for commercial buildings
To fix electricity tariffs for buildings
To mandate use of only renewable energy in construction
To regulate real estate prices
Answer: A) To set minimum energy efficiency standards for commercial buildings
Confirmed vs Book-1 §2.3.1 — ECBC was developed to deal with rapidly rising energy consumption in commercial buildings and 'sets minimum energy efficiency standards for design and construction of commercial buildings', with norms per square metre by climatic region. It does not fix tariffs, does not mandate renewables-only construction and has nothing to do with real-estate prices.

📖 § Measurement & Verification in performance contracting (general)
54. The main purpose of Performance Measurement and Verification (PMV) is to:
Establish new project costs
Ensure that guaranteed savings have been achieved
Increase the baseline consumption
Eliminate the need for utility bills
Answer: B) Ensure that guaranteed savings have been achieved
Confirmed vs Book-1 §2 (general) — Performance measurement and verification compares post-implementation consumption against an agreed baseline to confirm that the savings guaranteed by the project have actually been achieved — that is what triggers payment in a performance contract. It neither establishes project cost nor raises the baseline, and utility bills remain the primary data source.

📖 §2.2 EC Act 2001 — BEE as central nodal agency (chapter objective Q3)
57. The nodal/implementing agency for energy efficiency at the Central level under the EC Act 2001 is:
Central Electricity Authority (CEA)
Bureau of Energy Efficiency (BEE)
Ministry of New and Renewable Energy
National Productivity Council
Answer: B) Bureau of Energy Efficiency (BEE)
Confirmed vs Book-1 §2.2/§2.3 — the EC Act 2001 "provides a legal mandate for the implementation of the energy efficiency measures through the institutional mechanism of Bureau of Energy Efficiency (BEE) in the Central Government and designated agencies in each state" (§2.6, NMEEE).
The book's own chapter objective Q3 asks for "the nodal agency at the centre for implementing the EC act" and the answer is BEE; all the schemes in §2.3 (ECBC, S&L, DSM, BLY, SME, DC/PAT, certification) are BEE schemes.
Option (a) CEA is the technical adviser under the Electricity Act 2003 (§2.4), not the EC Act nodal agency; the State-level implementer is the SDA.

2003
2007
2010
2012
Answer: C) 2010
Confirmed vs Book-1 §2.3.6 and the List of Acts — the Act is cited as "[Act 52 of 2001, dt. 29-9-2001] [As amended by Act No. 28 of 2010, dt. 4-8-2010]", and PAT's "genesis ... flows out of the provision of the Energy Conservation Act, 2001 (amended in 2010)".
The same 2010 amendment brought in Energy Savings Certificates (Section 14A) and the non-compliance penalty under Section 26(1A).
Option (b) 2007 is the ECBC year and (a) 2003 the Electricity Act year — both are different instruments, not EC Act amendments.

📖 §2.3.6 Designated Consumers — the 9 notified energy-intensive industries
59. Which of the following is NOT a notified designated consumer (energy-intensive industry) under the EC Act?
Cement
Fertilizer
Automobile
Iron & Steel
Answer: C) Automobile
Confirmed vs Book-1 §2.3.6 — the Central Government has notified NINE energy-intensive industries as designated consumers: Thermal Power Stations, Fertilizer, Cement, Iron & Steel, Chlor-Alkali, Aluminium, Railways, Textile and Pulp & Paper.
Automobile does not appear anywhere in that Schedule, so it is not a notified designated consumer.
Options (a), (b) and (d) are all in the list (each at the 30,000 MTOE/year threshold), which makes them tempting but wrong for a NOT question.

📖 §2.1 Definitions — 'Building' under the EC Act (chapter objective Q4)
60. A commercial building qualifies as a designated consumer if its connected load is at least:
50 kW or 60 kVA
100 kW or 120 kVA
200 kW or 250 kVA
500 kW or 600 kVA
Answer: B) 100 kW or 120 kVA
Confirmed vs Book-1 §2.1 — a building under the Act is one "which is having a connected load of 100 Kilowatt (kW) or contract demand of 120 Kilo-volt Ampere (kVA) and above and is used or intended to be used for commercial purposes".
Both limbs matter: 100 kW connected load OR 120 kVA contract demand, and the use must be commercial.
Options (c) and (d) inflate the threshold; option (a) halves it — none matches the definition in the Act.
61. Under the PAT scheme, Energy Savings Certificates (ESCerts) are:
Issued for any energy use and freely sold to the public
Issued for savings beyond target and traded between designated consumers
A penalty imposed on inefficient units
A subsidy paid in cash by BEE
Answer: B) Issued for savings beyond target and traded between designated consumers
Confirmed vs Book-1 §2.3.6 — units "who achieve superior savings ... receive energy savings certificates for this excess savings, and ... trade the additional certified energy savings certificates with other designated consumers"; ESCerts "will be tradable at Power Exchanges" and may be banked for the next PAT cycle.
So ESCerts reward savings BEYOND the mandated specific-energy-consumption target and circulate only among designated consumers.
Option (a) is wrong on both counts (not for any energy use, not sold to the public); (c) confuses ESCerts with the Section 26(1A) penalty for missing the target.

📖 §2.3.2 Standards and Labeling — Star Ratings
62. In the Standards & Labeling (S&L) programme, a star rating of 5 indicates an appliance that is:
The least efficient
The most efficient
Average efficiency
Not certified
Answer: B) The most efficient
Confirmed vs Book-1 §2.3.2 — "Depending upon the performance of an appliance, they are rated on a scale of star 1 to star 5 ... Star 1 is the least energy efficient (and hence the least money saved) and star 5 is the most energy efficient (and hence more money saved)."
The label's message is 'More stars, more savings', so 5 stars is the top of the scale.
Option (a) simply inverts the scale — the classic trap; (d) is wrong because a star-rated appliance is by definition certified under the S&L programme.

📖 §2.3.1 Energy Conservation Building Codes (ECBC) (chapter objective Q8)
63. The Energy Conservation Building Code (ECBC), 2007 sets minimum energy-efficiency norms expressed:
Per kilowatt of connected load
Per square metre, adjusted by climate zone
Per occupant of the building
Per floor of the building
Answer: B) Per square metre, adjusted by climate zone
Confirmed vs Book-1 §2.3.1 and the §2.1 definition — energy conservation building codes are "the norms and standards of energy consumption expressed in terms of per square meter of the area"; ECBC "defined the norms of energy requirement per sq.metre of area and takes into consideration the climatic region of the country, where the building is located".
ECBC 2007 applies to commercial buildings, and State Governments may modify the codes to suit regional and local climatic conditions.
Options (a), (c) and (d) use bases (connected load, occupant, floor) that the Act's definition never mentions.

Confirmed vs Book-1 §2.3.2 — four equipment were brought under MANDATORY S&L from 7th January 2010: Household Frost Free Refrigerators, Room Air Conditioners, Tubular Fluorescent Lamps and Distribution Transformers (up to 200 kVA).
Frost-free refrigerators are therefore mandatory, which makes (c) the answer.

65. The National Action Plan on Climate Change (NAPCC, 2008) consists of how many national missions?
5 missions
6 missions
8 missions
10 missions
Answer: C) 8 missions
Confirmed vs Book-1 §2.6 — "There are eight National Missions which form the core of the National Action Plan": Solar, Enhanced Energy Efficiency, Sustainable Habitat, Water, Sustaining the Himalayan Ecosystem, Green India, Sustainable Agriculture and Strategic Knowledge for Climate Change.
The NAPCC document itself was released in 2008 by the Prime Minister's Council on Climate Change.
The chapter's own short question S-4 asks the student to list five of these eight, so the count of 8 is directly examinable; the other options do not match the book's list.
66. Renewable Purchase Obligation (RPO), which mandates a minimum share of renewable energy in a utility's portfolio, was introduced through:
EC Act 2001
Electricity Act 2003
ECBC 2007
Integrated Energy Policy 2006
Answer: B) Electricity Act 2003
Confirmed vs Book-1 §2.4 — "A significant regulatory impact on renewable energy was made by the Electricity Act, 2003, which provides for the determination of quotas or Renewable Purchase Obligation (RPO) by the State Electricity Regulatory Commissions (SERC)."
Internationally the same instrument is called the Renewable Portfolio Standard (RPS); a retailer can comply by owning a renewable facility or by purchasing renewable power.
Option (a) is the tempting one, but the EC Act 2001 deals with energy efficiency (BEE, DCs, ECBC, S&L) and contains no renewable purchase quota.

📖 §2.3.6 Designated Consumers — Energy conversion values for MTOE (chapter objective Q7)
67. Under the EC Act conversions, 1 kilogram of oil equivalent equals:
1000 kcal
10,000 kcal
100,000 kcal
10^7 kcal
Answer: B) 10,000 kcal
Confirmed vs Book-1 §2.3.6 — the conversion table states "i) 1 kg of Oil Equivalent: 10000 kcal; ii) 1 Metric Tonne of Oil Equivalent (MTOE): 1 x 10⁷ kcal".
These are the values a designated consumer must use to work out annual energy consumption in MTOE.
Option (d) 10⁷ kcal is the value for one METRIC TONNE of oil equivalent, not one kilogram — the most common slip in this question.
68. Under the Bachat Lamp Yojana (BLY), the cost gap of supplying CFLs at about Rs 15 was recovered through:
Direct cash subsidy from BEE
The Clean Development Mechanism (CDM)
ESCerts trading
State electricity duty
Answer: B) The Clean Development Mechanism (CDM)
Confirmed vs Book-1 §2.3.4 — BLY "plans to use the Clean Development Mechanism (CDM) to recover the cost difference between the market price of the CFLs and the price at which they are sold to households", with CFLs sold at Rs. 15 each.
It is structured as a public-private partnership between the Government of India, private CFL suppliers/investors and the DISCOMs, and delivers about 80% energy saving without loss of lumen intensity.
Option (a) is wrong because BEE pays no direct cash subsidy under BLY, and (c) confuses BLY with the PAT/ESCerts market for designated consumers.

state designated agencies
all industrial consumers
designated consumers
electrical distribution licensees
Answer: C) designated consumers
Learn the pairing that this question and its twins turn on: the designated consumer must DESIGNATE OR APPOINT a certified Energy MANAGER (an in-house post), and must get the energy audit done by an ACCREDITED Energy AUDITOR (an external professional on BEE's list). State Designated Agencies enforce the Act within a state; they do not appoint the manager. Hook: manager inside, auditor outside.

certified energy manager
certified energy auditor
accredited energy auditor
state Designated Agencies
Answer: C) accredited energy auditor
The exact words in the Act are 'get an energy audit conducted by an ACCREDITED energy auditor'. Note the three-tier vocabulary: certified energy manager, certified energy auditor (has passed the exam), accredited energy auditor (certified AND accredited by BEE, i.e. on the maintained list). Only the accredited one may sign a designated consumer's statutory audit — picking 'certified energy auditor' is the intended trap.

72. ESCerts cannot be
bought

traded directly between DCs
Answer: D) traded directly between DCs
ESCerts are issued to a DC that beats its notified SEC reduction target, and the book says they are 'tradable at Power Exchanges' (IEX/PXIL) and may be BANKED for the next PAT cycle. So buying, selling and banking are all allowed; what is not allowed is a direct bilateral deal between two designated consumers outside the exchange. Hook: trade on the exchange, never over the fence.

📖 §2.3.1 Energy Conservation Building Codes (ECBC)
73. A building intended to be used for commercial purpose will be required to follow Energy conservation building code under Energy Conservation Act, 2001 provided its
connected load is 120 kW and above
contract demand is 100 kVA and above
connected load is100 kW and above or contract demand is 120 kVA and above
connected load is 500 kW and contract demand is 600 kVA
Answer: C) connected load is100 kW and above or contract demand is 120 kVA and above
Memorise the threshold exactly as the Act defines a commercial building: connected load of 100 kW OR contract demand of 120 kVA and above. The examiner's favourite trick is to swap the two numbers (120 kW / 100 kVA). Hook: kW is the smaller number, kVA the larger — 100 kW, 120 kVA, and it is OR, not AND.

74. Frequency of energy audit for designated consumers is
once in a year
once in two years
once in three years
Once in five years
Answer: C) once in three years
Two dates, both examinable: the FIRST energy audit must be completed within 18 MONTHS of the Central Government's notification, and every SUBSEQUENT audit at an interval of THREE YEARS counted from the date the previous audit report was submitted to the management. Hook: 18 months to start, 3 years to repeat. Note the clock runs from report submission, not from the audit date.
Answer: C) Standards & Labeling. The BEE star label (1 to 5 stars) on appliances is the comparative label under the Standards & Labelling programme mandated by Section 14 of the EC Act 2001. Derived; the printed answer-key column was not legible in the scan for this question.
Star rating is the COMPARATIVE label of the S&L programme, backed by Section 14(d) of the Act (particulars to be displayed on the label). Keep the four schemes cleanly separated because they rotate through the papers: S&L = star labels on appliances, ECBC = codes for commercial buildings, PAT/DC = SEC targets and ESCerts for industry, BLY = CFL/LED distribution under CDM.

Answer: D) Sugar. The sectors notified as designated consumers under Schedule of the EC Act 2001 include fertilizers, chlor-alkali, cement, aluminium, iron & steel, pulp & paper, textile, railways, thermal power stations and electricity distribution companies. The sugar industry is not among them. Derived - the question paper carries no printed answer key for Section-I.
Run the nine-sector list mentally and eliminate: Thermal Power, Fertilizer, Cement, Iron & Steel, Chlor-Alkali, Aluminium, Railways, Textile, Pulp & Paper. Sugar is not on the 2014 list, and neither are refineries, glass or ceramics — those are the usual decoys. Hook: nine sectors, no sugar.
77. The annual MTOE limit for chloroalkali industry to be a designated consumer is
30000
3000
7500
12000
Answer: D) 12,000 metric tonnes of oil equivalent per year is the notified threshold for the chlor-alkali sector to be a designated consumer under the EC Act 2001. Derived - the question paper carries no printed answer key for Section-I.
Chlor-alkali sits alone at 12,000 metric tonnes of oil equivalent per year. The full table: 30,000 for thermal power stations, fertilizer, cement, iron & steel, railways and pulp & paper; 12,000 chlor-alkali; 7,500 aluminium; 3,000 textile.

📖 §2.3.1 Energy Conservation Building Codes (ECBC) — Energy Performance Index
78. As per ECBC, EPI calculation includes
Solar photovoltaic Energy
Grid energy purchased
captive DG power
Both b and c
Answer: D) Both b and c. The Energy Performance Index (kWh/sq.m/year) under ECBC counts the energy purchased from the grid plus the energy generated by captive DG sets; on-site renewable (solar PV) generation is excluded from the numerator. Derived - the question paper carries no printed answer key for Section-I.
EPI = annual energy consumption of the building in kWh divided by its built-up area in square metres, i.e. kWh/sq.m/year. It counts energy DELIVERED to the building — grid purchase plus captive DG generation. On-site renewable generation such as roof-top solar PV is excluded, which is exactly why installing PV improves a building's EPI. Hook: if it came from outside the fence or from your own diesel, it counts.

Answer: C) Bureau of Energy Efficiency (BEE), set up on 1st March 2002 under the provisions of the Energy Conservation Act 2001 as the central nodal agency. Derived - the question paper carries no printed answer key for Section-I.
BEE was set up on 1 March 2002 under the EC Act 2001 as the central nodal agency, with the State Designated Agencies as its counterparts in the states.

80. As per Energy Conservation Act, 2001 appointment of BEE Certified Energy Manager is mandatory for
All commercial buildings
All State designated agencies
All large Industrial consumers
All designated consumers
Answer: D) All designated consumers. Section 14(l) of the EC Act requires every designated consumer to designate or appoint a certified energy manager. Derived - the question paper carries no printed answer key for Section-I.
The obligation is attached to the designated consumer specifically, not to size or building type. A large industrial consumer that is not in a notified sector, or is below the toe threshold, has NO statutory obligation to appoint an energy manager — which is why 'all large industrial consumers' is wrong. Same rule as the audit obligation: DC status is the trigger for every duty under Sections 14 and 15.

📖 §2.3.6 Designated consumers — PAT scheme and ESCerts
82. ESCerts cannot be
Bought
Sold

Energy Saving Certificates are bought and sold only through the notified power exchanges (IEX and PXIL) under the PAT scheme; bilateral trading directly between designated consumers is not permitted. They can be bought, sold and banked. Derived - the question paper carries no printed answer key for Section-I.
Same rule as the earlier twin: bought, sold and banked for the next cycle are all permitted; only a direct bilateral transfer between two DCs outside the exchange is not. The book's sentence is 'ESCerts so issued will be tradable at Power Exchanges' — trading is exchange-routed so that price discovery is transparent and the registry can track surrender.

84. Under the Standards and Labeling (S&L) Scheme of the BEE,
Building codes are prescribed for commercial buildings
Industries are required to meet specific energy targets
Energy Star labels are affixed on appliances
LED Lamps are distributed
Answer: C) Energy Star (star rating) labels are affixed on appliances. Building codes for commercial buildings come under ECBC; specific energy targets for industry come under the PAT scheme; LED distribution is the UJALA programme of EESL. Derived - the question paper carries no printed answer key for Section-I.
Map each distractor to the scheme it actually belongs to and the answer falls out: building codes for commercial buildings = ECBC (§2.3.1); specific energy targets for industry = PAT/designated consumers (§2.3.6); LED/CFL distribution = Bachat Lamp Yojana (§2.3.4). What is left — energy star labels affixed on appliances — is S&L. Doing this mapping is faster and safer than reasoning about the S&L definition itself.

📖 § Electricity Act 2003 / Renewable energy (RPO/RPS)
1. Explain what is meant by Renewable Purchase Obligation (RPO).
Model answer: RPO is a regulatory mandate, introduced through the Electricity Act 2003, under which the State Electricity Regulatory Commissions (SERCs) fix a minimum quota of renewable energy that must be included in the resource portfolio of every obligated entity (distribution licensees, open-access and captive users). Internationally it is called the Renewable Portfolio Standard (RPS). The retailer can meet the obligation by owning a renewable facility and generating its own power or by purchasing renewable power from another facility.

37. Explain the PAT (Perform, Achieve and Trade) scheme and why it is a market-based mechanism.
Model answer: PAT is a market-based mechanism to enhance the cost-effectiveness of energy-efficiency improvements in energy-intensive large industries through certification of energy savings that can be traded; it flows from the EC Act 2001 (amended 2010). It mandates specific energy consumption (SEC) reduction targets for designated consumers across 8 sectors (Aluminium, Cement, Chlor-Alkali, Fertilizer, Iron & Steel, Pulp & Paper, Textile, Thermal Power) - smaller targets for efficient units and larger for inefficient ones. Units that exceed their target earn Energy Savings Certificates (ESCerts), tradable at Power Exchanges with other DCs (who use them to meet targets) and bankable for the next cycle, making it market-based. Failure attracts penalty under Section 26(1A).
38. What are ESCerts and explain the basis for their issuance and trading under the PAT scheme.
Model answer: Energy Savings Certificates (ESCerts) are tradable certificates issued under PAT to designated consumers who achieve energy savings beyond their notified specific energy consumption (SEC) reduction target. The number of ESCerts issued depends on the quantum of energy saved over and above the target in the assessment year. DCs that fall short of their target must purchase ESCerts (or face penalty under Section 26(1A)) to comply; ESCerts are tradable between designated consumers at Power Exchanges and may be banked for the next PAT cycle.
Issued for over-target savings; traded between DCs at Power Exchanges; bankable.

📖 §2.3.6 Designated consumers — PAT scheme and ESCerts
53. What are ESCerts and explain the basis for their issue and trading under PAT scheme ?
Model answer: PAT scheme provides the option for industries who achieve superior savings to receive energy savings certificates for this excess savings, and to trade the additional certified energy savings certificates with other designated consumers (energy intensive industries notified as Designated Consumers under the Energy Conservation Act and included under PAT Scheme) who can utilize these certificates to comply with their specific energy consumption reduction targets. Energy Savings Certificates
(ESCerts) so issued will be tradable at Power Exchanges. The scheme also allows units which gain ESCerts to bank them for the next cycle of PAT, following the cycle in which they have been issued.

Structure: (i) what — Energy Saving Certificates, a tradable instrument denominated in metric tonnes of oil equivalent of energy saved; (ii) basis of issue — the quantum of energy saved OVER AND ABOVE the notified SEC reduction target in the assessment year, after verification and check-verification by an accredited energy auditor firm; (iii) trading — sold on the notified power exchanges to DCs that fell short, who surrender them for compliance, with banking allowed into the next cycle. Add that shortfall attracts penalty under Section 26(1A) of the amended Act — that sentence usually carries a mark.

📖 §2.3.6 Designated consumers — Perform, Achieve and Trade (PAT)
55. Explain PAT scheme and why it is a market based mechanism?
Model answer: Perform, Achieve and Trade (PAT) Scheme is a market based mechanism to enhance cost effectiveness of improvements in energy efficiency in energy-intensive large industries and facilities, through certification of energy savings that could be traded. The genesis of the PAT mechanism flows out of the provision of the
Energy Conservation Act, 2001 (amended in 2010).
The key goal of PAT scheme is to mandate specific energy efficiency improvements for the most energy intensive industries in sectors as listed below.
Sector
1. Aluminium
2. Cement
3. Chlor-Alkali
4. Fertilizer
5. Iron and Steel
6. Pulp and Paper
7. Textile
8. Thermal Power Plant
The energy intensity reduction target mandated for each unit is depended on its operating efficiency and the specific energy consumption reduction target is less for those who are more efficient and more for the less efficient units.
Further, the scheme incentivizes units to exceed their specified SEC improvement targets. To facilitate this, the scheme provides the option for industries who achieve superior savings to receive energy savings certificates for this excess savings, and to trade the additional certified energy savings certificates with other designated consumers who can utilize these certificates to comply with their specific energy consumption reduction targets. Energy Savings Certificates (ESCerts) so issued will be tradable at Power Exchanges. The scheme also allows units which gain ESCerts to bank them for the next cycle of PAT, following the cycle in which they have been issued.
The number of ESCerts which would be issued would depend on the quantum of energy saved over and above the target energy savings in the assessment year.
After completion of baseline audits, targets varying from unit to unit ranging from about 3 to 7% are set and need to be accomplished during the 3 year cycle; after which new cycle with new targets will be proposed. Failing to achieve the specific energy consumption targets in the time frame would attract penalty for the non-compliance under Section
26 (1A) of the Energy Conservation Act, 2001 (amended in 2010). For ensuring the compliance with the set targets, system of verification and check-verification will be carried out by empanelment criteria of accredited energy auditors.

PAT is described in the book as a market based mechanism to enhance the cost effectiveness of energy efficiency improvements in energy-intensive large industries through certification of energy savings that can be traded. It is 'market based' because each DC gets a unit-specific SEC reduction target (lighter for the already-efficient, heavier for the laggard), and over-achievers earn ESCerts that under-achievers must buy on the power exchange — so a price emerges and the saving is delivered wherever it costs least. First-cycle targets ranged about 3 to 7%, to be met by 2014-15. Say 'trading creates a price signal' explicitly for the mark.

📖 §2.3.6 Designated consumers — PAT scheme and ESCerts
58. What are ESCerts and explain the basis for their issuance and trading under PAT scheme? (5 Marks)
Model answer: Refer BEE Guidebook Book-1, Pages 40-41. Energy Saving Certificates (ESCerts) are tradable instruments issued under the Perform, Achieve and Trade (PAT) scheme of the National Mission for Enhanced Energy Efficiency. Each designated consumer is given a specific energy consumption (SEC) reduction target for the PAT cycle. A DC that outperforms its target is issued ESCerts by the Ministry of Power on the recommendation of BEE, one ESCert representing one metric tonne of oil equivalent of energy saved in excess of the target. A DC that falls short of its target must either buy ESCerts to make good the shortfall or pay a penalty. ESCerts are traded on the power exchanges (IEX and PXIL) and cannot be traded bilaterally between designated consumers.
Build the answer in three blocks for the five marks: definition (a tradable certificate denominated in metric tonnes of oil equivalent, issued under PAT, which flows from the EC Act 2001 as amended in 2010); basis of issue (energy saved beyond the notified SEC reduction target in the assessment year, established by verification and check-verification by an accredited energy auditor firm); trading and banking (traded only on notified power exchanges, may be banked to the next cycle, surrendered by shortfall DCs, with penalty under Section 26(1A) if the target is missed). Naming Section 26(1A) and the power exchange are the two details that separate 3 marks from 5.

📖 §2.4 Electricity Act 2003 (RPO); §2.3.3 Demand Side Management
60. Write a short note on the following: a) Renewable Purchase Obligation. (2 Marks) b) List three benefits of Demand Side Management (DSM). (3 Marks)
Model answer: a) Refer BEE Guidebook Book-1, Pages 44-45. The Renewable Purchase Obligation is the mandate under the Electricity Act 2003 and the National Tariff Policy by which the State Electricity Regulatory Commission fixes a minimum percentage of the total electricity that an obligated entity (distribution licensee, open-access consumer, captive user) must procure from renewable energy sources; compliance may also be met by purchasing Renewable Energy Certificates (RECs).
b) Refer BEE Guidebook Book-1, Page 38. Three benefits of DSM: (i) it reduces the peak demand and flattens the load curve, deferring or avoiding costly investment in new generation, transmission and distribution capacity; (ii) it lowers the consumer's energy bill and the utility's cost of supply, and improves system load factor and reliability; (iii) it reduces fuel consumption and hence greenhouse gas and other emissions.
(a) RPO is the obligation placed by each State Electricity Regulatory Commission, under the Electricity Act 2003 and the National Tariff Policy, on distribution licensees (and certain captive/open-access consumers) to buy a MINIMUM PERCENTAGE of their energy from renewable sources; compliance may be met by buying Renewable Energy Certificates instead of physical power. Say 'minimum percentage fixed by the SERC' — that phrase is the mark. (b) For DSM benefits, name load-shape actions and their effect: peak clipping defers new peaking capacity and cuts the utility's cost of supply; load shifting/valley filling improves the load factor and system utilisation; strategic conservation cuts the consumer's bill and the associated emissions and T&D losses.

7. Explain the Standards and Labelling (S&L) programme of BEE — its objectives, main provisions of the EC Act, and the terms Standard, Label, MEPS and Star Rating.
Model answer: Rationale: There is wide variation in energy consumption of similar products by different manufacturers, and energy-consumption information is often not easily available, leading to continued manufacture and purchase of inefficient equipment.
Objective: To provide the consumer an informed choice about the energy-saving and cost-saving potential of marketed household and other equipment, thereby driving energy savings in the medium and long run and positioning domestic industry to compete where energy-efficiency norms are mandatory.
Main provisions of the EC Act on S&L:
- Recommend to the Central Government the norms for processes and energy-consumption standards for equipment which consumes, generates, transmits or supplies energy.
- Recommend particulars to be displayed on the label and the manner of display.
- Prevent manufacture, sale and import of equipment that does not comply with notified standards.
- Promote use of energy-efficient processes, equipment, devices and systems, and spread information on benefits to consumers.
Key terms:
- Standard: procedures/regulations prescribing the energy performance of manufactured products, sometimes prohibiting sale below a minimum level; covers (a) test protocols and (b) target limits on energy performance.
- Label: an informative tag affixed to a product describing its energy performance to help consumers make informed purchases. Two types — Comparative label (allows comparison of models) and Endorsement label (marks products meeting minimum criteria).
- MEPS (Minimum Energy Performance Standards): prescribe minimum efficiency/maximum consumption a product must achieve, reviewed and upgraded periodically.
- Star Rating: a ranking (1 to 5 stars) declared by the manufacturer; Star 1 = least efficient (least savings), Star 5 = most efficient (most savings).
Mandatory labelling (4 items from 7 Jan 2010): Frost-Free Refrigerators, Room Air Conditioners, Tubular Fluorescent Lamps (TFL), and Distribution Transformers (up to 200 kVA).

📖 Energy Conservation Building Code (ECBC)
8. Write a detailed note on the Energy Conservation Building Code (ECBC) — its purpose, features and how it is enforced.
Model answer: Background: The Energy Conservation Building Code (ECBC), launched by the Ministry of Power in 2007, was developed to deal with rapidly increasing energy consumption in commercial buildings.
Purpose: ECBC sets minimum energy-efficiency standards for the design and construction of commercial buildings.
Salient features:
- It encourages energy-efficient design or retrofit of buildings so that building function, comfort, health and occupant productivity are maintained, and life-cycle costs (construction plus energy cost) are minimized.
- ECBC defines the norms of energy requirement per square metre of area and takes into consideration the climatic region of the country in which the building is located.
- Owners/occupiers must comply with the energy-consumption norms and standards, and/or prepare and implement schemes for efficient use and conservation of energy.
Enforcement:
- The Central Government can prescribe energy conservation building codes and direct owners/occupiers to comply with them.
- State Governments can modify (amend) the codes to suit regional and local climatic conditions and notify them for buildings in the State.
- Under the Act, an owner/occupier being a designated consumer may be directed to get a building energy audit conducted by an accredited energy auditor.
(For detailed energy conservation in buildings, the Guidebook refers the reader to Book-3, Chapter 10.)

📖 Certification of Energy Managers & Accreditation of Energy Auditors
9. Explain the certification of Energy Managers and the qualification/accreditation of Energy Auditors under the EC Act framework.
Model answer: Purpose: A cadre of professionally qualified energy managers and auditors — with expertise in policy analysis, project management, financing and implementation of energy-efficiency projects — is developed through a Certification and Accreditation programme. BEE designs the training modules and regularly conducts a National-level examination for certification of energy managers and energy auditors.
Certified Energy Manager: A person who qualifies the National Certification Examination conducted by BEE. Designated consumers are required to appoint/designate an energy manager with the prescribed minimum qualifications, in charge of activities for efficient use of energy and its conservation.
Accredited Energy Auditor — qualification (Qualifications for Accredited Energy Auditors and Maintenance of their List, Regulations 2009/2010): An energy auditor is qualified to become an Accredited Energy Auditor if he/she:
(a) is a Certified Energy Manager and has passed the examination in 'Energy Performance for Equipment and Utility Systems' conducted by the Bureau;
(b) has an experience of five years in energy audit, out of which at least three years shall be in any of the energy-intensive industries;
(c) has been granted a certificate of accreditation by the Bureau of Energy Efficiency.
The Accreditation Advisory Committee constituted by BEE assesses the energy-audit experience and competence of the applicant on the basis of an oral interview before granting the certificate of accreditation. BEE maintains the list of accredited energy auditors.
Energy audit (Act definition): the verification, monitoring and analysis of use of energy, including submission of a technical report containing recommendations for improving energy efficiency with cost-benefit analysis and an action plan to reduce energy consumption.

📖 Section 26 — Penalties and Adjudication
10. Explain the provisions relating to penalties and adjudication under the Energy Conservation Act, 2001.
Model answer: Chapter VIII of the EC Act deals with Penalties and Adjudication. Section 26 provides:
(1) If any person fails to comply with specified provisions — clauses (c), (d), (h), (i), (k), (l), (r) or (s) of Section 14, or clauses (b), (c) or (h) of Section 15 — he shall be liable to a penalty not exceeding ten lakh rupees for each such failure, and in the case of continuing failure, an additional penalty which may extend to ten thousand rupees for every day during which the failure continues.
Proviso: No person shall be liable to pay penalty within five years from the date of commencement of the Act.
(1A) If any person fails to comply with clause (n) of Section 14 (compliance with energy-consumption norms and standards), he shall be liable to a penalty not exceeding ten lakh rupees and, in the case of continuing failure, an additional penalty not less than the price of every metric tonne of oil equivalent of energy (prescribed under the Act) that is in excess of the prescribed norms. This clause is the basis for penalising non-compliance under the PAT scheme.
(2) Any amount payable under this section, if not paid, may be recovered as if it were an arrear of land revenue.
Adjudication and appeals: Disputes are adjudicated as provided under the Act, and an Appellate Tribunal for Energy Conservation (Procedure, Form, Fee and Record of Proceedings Rules, 2012) hears appeals against orders.

📖 Perform, Achieve and Trade (PAT) scheme
11. Explain the Perform, Achieve and Trade (PAT) scheme and its potential impact, including the sectors covered.
Model answer: Perform, Achieve and Trade (PAT) is a market-based mechanism to enhance the cost-effectiveness of energy-efficiency improvements in energy-intensive large industries and facilities, through certification of energy savings that can be traded. Its genesis lies in the Energy Conservation Act, 2001 (amended in 2010).
Key goal: To mandate specific energy-efficiency improvements for the most energy-intensive industries.
Mechanism:
- The scheme builds on the large variation in energy intensities of different units in almost every sector and mandates a Specific Energy Consumption (SEC) reduction target for each unit.
- Targets are graded by operating efficiency: the reduction target is smaller for more-efficient units and higher for less-efficient units (targets ranged from about 3 to 7%).
- Units that exceed their SEC reduction targets earn Energy Savings Certificates (ESCerts) for the excess savings.
- ESCerts are tradable at Power Exchanges and can be traded with other designated consumers who need them to meet their targets; units may also bank ESCerts for the next PAT cycle.
Coverage (1st cycle, assessment year 2014-15): 478 Designated Consumers across 8 energy-intensive sectors — Aluminium (10), Cement (85), Chlor-Alkali (22), Fertilizer (29), Iron & Steel (67), Pulp & Paper (31), Textile (90) and Thermal Power (144).
Compliance & penalty: Verification and check-verification are carried out through empanelled accredited energy auditors. Failure to achieve the SEC targets within the time frame attracts penalty for non-compliance under Section 26(1A) of the EC Act.
Impact: Drives measurable energy-intensity reduction in the most energy-intensive industries, creates a tradable market in energy savings, and rewards over-achievers while penalising non-compliance.

Model answer: The Bachat Lamp Yojana (BLY), literally 'Save Lamp Scheme', aims at the large-scale replacement of inefficient incandescent bulbs in households by Compact Fluorescent Lamps (CFLs).
Objective & mechanism:
- It seeks to provide CFLs to households at a price similar to that of incandescent bulbs (about Rs 15 per CFL).
- The cost difference between the market price of the CFL and the subsidised price is recovered by using the Clean Development Mechanism (CDM) — i.e. selling the carbon emission reductions achieved by the energy savings.
Structure (Public-Private Partnership): BLY is designed as a PPP between the Government of India, investors/private-sector CFL suppliers, and State-level Electricity Distribution Companies (DISCOMs). The CFL supplier/investor is selected by the DISCOM from a list of CFL suppliers empanelled by BEE, and sells high-quality CFLs to households at Rs 15 within a designated project area in a DISCOM's region.
Savings: Under the scheme, 60 W and 100 W incandescent lamps are replaced with 11-15 W and 20-25 W CFLs respectively. It is estimated that about 80% energy savings can be achieved without affecting lumen intensity.
Outcome: Of 50 small-scale BLY projects registered under the umbrella framework, 43 were implemented, and about 29.5 million CFLs were distributed during the XI Plan period. (Under NMEEE's MTEE, the BLY institutional structure was later envisaged for the promotion of LEDs.)
From OCR §2.3.4 — CFL @ Rs 15, CDM cost recovery, PPP, 60/100 W to 11-15/20-25 W, 80% savings, 29.5 million CFLs. Chapter end Long Q L-1.

📖 National Mission for Enhanced Energy Efficiency (NMEEE) & its four initiatives
13. Explain the National Mission for Enhanced Energy Efficiency (NMEEE) and describe its four initiatives.
Model answer: The National Mission for Enhanced Energy Efficiency (NMEEE) is one of the eight National Missions under the National Action Plan on Climate Change (NAPCC). The EC Act 2001 provides the legal mandate for implementing energy-efficiency measures through BEE (Centre) and the designated agencies in each State. NMEEE aims to strengthen the market for energy efficiency by creating a conducive regulatory and policy regime and by fostering innovative and sustainable business models. It was approved for two years of the 11th Plan (2010-11 and 2011-12) with an outlay of Rs 235.50 crore, and continued into the 12th Plan with an outlay of Rs 775 crore.
The four initiatives of NMEEE are:
1. Perform, Achieve and Trade (PAT): a market-based mechanism to enhance cost-effectiveness of energy-efficiency improvements in energy-intensive industries through certification of energy savings that can be traded (ESCerts).
2. Market Transformation for Energy Efficiency (MTEE): accelerates the shift to energy-efficient appliances in designated sectors through innovative measures to make products more affordable — it includes the Bachat Lamp Yojana (BLY) and the Super-Efficient Equipment Programme (SEEP, e.g. 35 W super-efficient ceiling fans).
3. Energy Efficiency Financing Platform (EEFP): creates mechanisms to help finance demand-side management programmes across sectors by capturing future energy savings; MoUs are signed with financial institutions.
4. Framework for Energy Efficient Economic Development (FEEED): develops fiscal instruments to promote energy efficiency, and set up two funds — the Partial Risk Guarantee Fund for Energy Efficiency (PRGFEE) and the Venture Capital Fund for Energy Efficiency (VCFEE).
Impact: NMEEE seeks to unlock the energy-efficiency market (estimated ~Rs 74,000 crore), achieve avoided capacity addition of about 19,598 MW, fuel savings of ~23 million tonnes/year, and GHG emission reduction of ~98.55 million tonnes/year at full implementation.
From OCR §2.6 NMEEE paragraphs — outlays, the four initiatives (PAT, MTEE incl. BLY & SEEP, EEFP, FEEED with PRGFEE & VCFEE), and the impact figures.

📖 §1.13 TOD tariff; §2.3.2 comparative and endorsement labels; §6 ISO 50001 (EnMS)
14. Write short notes on?
1. Time of the day tariff
2. Comparative label
3. Endorsement label
4. Benefits of ISO 50001
Model answer: 1) In Time of the Day Tariff (TOD) structure incentives for power drawl during off-peak hours and disincentives for power drawl during peak hours are built in.
Many electrical utilities like to have flat demand curve to achieve high plant efficiency.
ToD tariff encourage user to draw more power during off-peak hours (say during
11pm to 5 am, night time) and less power during peak hours. Energy meter will record peak and off-peak consumption and normal period separately.
ToD tariff gives opportunity for the user to reduce their billing, as off peak hour tariff is
quite low in comparison to peak hour tariff.
This also helps the power system to minimize in line congestion, in turn higher line
losses and peak load incident and utilities power procurement charges by reduced demand

4) ISO 50001 will provide the following benefits
A framework for integrating energy efficiency into management practices
Making better use of existing energy-consuming assets
Benchmarking, measuring, documenting, and reporting energy intensity
improvements and their projected impact on reductions in greenhouse gas (GHG) emissions
Transparency and communication on the management of energy resources
Energy management best practices and good energy management behaviours
Evaluating and prioritizing the implementation of new energy-efficient technologies
A framework for promoting energy efficiency throughout the supply chain
Energy management improvements in the context of GHG emission reduction
projects.

Comparative label ranks a product against similar products on a scale so the buyer can compare (BEE's 1-to-5 star label, with the annual kWh printed on it); an endorsement label is a simple pass/fail seal of approval saying the product meets a threshold (e.g. Energy Star) with no ranking. Hook: comparative = how many stars, endorsement = yes or no. For ISO 50001 give benefits, not clauses: a systematic PDCA framework, top-management commitment and energy policy, baseline/EnPI-driven continual improvement, statutory compliance, credibility with customers and lenders.

📖 §2.3.2 Standards and Labelling (S&L) — labels, standards and MEPS
15. Explain the following: a) Comparative label (2 marks) b) Endorsement label (2 marks) c) Minimum energy performance standard (2 marks) d) Explain the difference between standards and labelling (4 marks)
Model answer: a) Comparative label - Refer BEE Guidebook Book-1, Page 36. It allows consumers to compare the energy performance of similar products on a scale (for example BEE's 1 to 5 star label), showing where a particular model stands relative to others in its class.
b) Endorsement label - Refer BEE Guidebook Book-1, Page 36. It is a 'seal of approval' mark given only to those models that meet or exceed a pre-set energy efficiency criterion (for example the US Energy Star mark); it carries no comparative scale.
c) Minimum energy performance standard (MEPS) - Refer BEE Guidebook Book-1, Page 36. A regulation that prescribes the minimum efficiency (or maximum energy consumption) a product must achieve; models below the level cannot legally be manufactured, imported or sold.
d) Difference between standards and labelling - Refer BEE Guidebook Book-1, Pages 35 & 36. Standards are prescriptive/mandatory limits on energy performance that remove inefficient products from the market, whereas labels are informative - they disclose the energy performance to the buyer at the point of sale and let market forces pull the market towards efficient products. Standards act on the manufacturer, labels act on the purchaser; the two are complementary and normally implemented together.
Comparative label: ranks a product against similar products on a scale (BEE 1-5 stars) with the annual energy consumption printed, so the buyer can compare. Endorsement label: a single seal certifying the product has crossed a threshold — no ranking, pass/fail. MEPS: a minimum energy performance standard, the floor below which a product may not legally be manufactured, sold or imported. For (d) the distinction is enforcement versus information: a STANDARD is a regulation, mandatory, removing bad products from the market and defined by a test protocol plus a target limit; a LABEL is disclosure, informing the buyer and letting the market choose. Hook: standards push the floor up, labels pull the ceiling up.
