Q1Consider the following statements: 1. CEA's Power Data Management Division publishes statistics concerning installed capacity, generation, transmission, trading, distribution and utilisation of electricity. 2. The division carries out quarterly monitoring of per capita consumption of electricity. 3. Its monthly installed-capacity reporting is limited only to privately owned generating stations. Which of the statements given above are correct?
Statements 1 and 2 are true. Statement 3 is false: the cited activity refers to monthly reporting of all-India installed generating capacity, with state-wise reviews based on PPA and central-pool allocation; it is not limited only to private stations.
Q2Consider the following statements: 1. Under the Electricity Act, 2003, conservation means reducing electricity consumption through improved efficiency in supply and use. 2. A distribution licensee is authorised only to generate electricity, not to maintain a distribution system. 3. Open access under the Electricity Act is non-discriminatory use of transmission lines, distribution systems or associated facilities by eligible users. 4. Captive generating plants have no right to open access for carrying electricity to their own use. Which of the statements given above are correct?
Statement 1 is correct because the Act defines conservation as reduced consumption resulting from efficiency improvements. Statement 2 is false; a distribution licensee operates and maintains a distribution system to supply consumers. Statement 3 is correct; open access is explicitly non-discriminatory use of network facilities. Statement 4 is false because a captive plant operator has a statutory right to open access for carrying power to the destination of its own use, subject to transmission availability.
Q31. The planning function of the Central Electricity Authority includes advice on the National Electricity Plan and integrated resource planning. 2. The planning function of the Central Electricity Authority excludes survey work on power demand growth. 3. The planning function of the Central Electricity Authority includes collection, compilation and publication of power-sector statistics. Which of the statements given above are correct?
Statements 1 and 3 are correct: CEA's planning responsibilities include the National Electricity Plan, integrated resource planning and power-sector statistics. Statement 2 is incorrect because the same official description specifically includes survey for power demand growth.
Q41. The 20th Electric Power Survey used Partial End Use Methodology for projecting electricity demand. 2. PEUM is described as a top-down method focused only on aggregate electricity sales. 3. In the 20th EPS, time-series analysis was used to derive growth indicators with higher weightage to recent trends. 4. The 20th EPS ignored energy-conservation initiatives and technological changes while deriving demand projections. Which of the statements given above are correct?
Statements 1 and 3 are correct. The 20th EPS used PEUM, and its time-series component gave higher weightage to recent trends. Statement 2 is false because PEUM is explicitly described as a bottom-up approach focused on end-use needs. Statement 4 is false because energy-conservation initiatives and technological changes were part of the rationale for weighting recent trends.
Q51. Perform, Achieve and Trade is a market-based mechanism. 2. It seeks to enhance energy efficiency in energy-intensive industries through tradable certification of energy savings. 3. Its main design is to give household consumers a flat electricity tariff irrespective of peak demand. Which of the statements given above are correct?
Statements 1 and 2 are correct. Statement 3 is incorrect: PAT is about energy efficiency in energy-intensive industries and tradable certification of savings, not flat household tariff design.

7Consider the following statements: 1. CEA's National Electricity Plan treats conventional sources, renewable sources and storage sources as part of generation-resource planning. 2. Coal/lignite is placed under new and renewable energy sources in the National Electricity Plan. 3. Storage sources listed by the National Electricity Plan include pumped storage systems, battery energy storage systems and green hydrogen. 4. The National Electricity Plan excludes large hydro from renewable-energy sources. Which of the statements given above are correct?
8Consider the following statements: 1. A generating company may establish, operate and maintain a generating station without a licence if it complies with the grid-connectivity technical standards. 2. A hydro-generating station is exempt from submitting any scheme to the Central Electricity Authority, irrespective of capital expenditure. 3. The Central Electricity Authority specifies technical standards for construction of electrical plants, electric lines and grid connectivity. 4. The Central Electricity Authority is barred from collecting data on generation, transmission, trading, distribution and utilisation of electricity. Which of the statements given above are correct?
9Consider the following statements: 1. The National Electricity Plan identifies pumped storage plants as a technically proven, large-scale storage option for variable solar and wind energy. 2. Pumped storage plants can help provide peaking power and maintain power-system stability. 3. Pumped storage plants are described as having no pumping losses and therefore 100% efficiency. 4. Pumped storage plants can provide ancillary benefits such as flexible capacity, voltage support and black-start facility. Which of the statements given above are correct?
10Consider the following statements: 1. NEP demand projections consider the impact of increased adoption of electric vehicles. 2. NEP demand projections exclude installation of solar rooftops and production of green hydrogen. 3. NEP's projected peak electricity demand and energy requirement are based on Electric Power Survey demand projections. Which of the statements given above are correct?
11Consider the following statements about load factor and electricity demand: 1. The 20th EPS says the load factor of a power system depends on the pattern of utilization of different types of load. 2. If a system feeds block industrial loads such as aluminium and other process industries, its overall load factor tends to be high. 3. The 20th EPS assumes that future load factor is always zero whenever demand-side management is introduced. 4. The 20th EPS says future electric load factor may need estimation when the pattern changes due to load shedding withdrawal, demand-side management or policy intervention. Which of the statements given above are correct?
12Consider the following statements: 1. Under the Electricity Act, 2003, open access means non-discriminatory use of transmission lines or distribution systems by eligible users. 2. A captive generating plant is set up primarily to generate electricity for sale to unrelated consumers. 3. The term power system includes generation, transmission, distribution and supply of electricity. Which of the statements given above are correct?
13Consider the following statements: 1. A DSM action plan can be prepared on the basis of load research carried out in distribution companies. 2. DSM interventions may help bring down both overall energy requirement and peak demand. 3. Demand management treats increasing supply as the only strategy for meeting electricity demand. Which of the statements given above are correct?
14Consider the following statements about the consumer-category treatment in electricity demand forecasting: 1. The 20th EPS made demand projections separately for categories such as domestic, commercial, irrigation, industries, public water works, public lighting and railways. 2. The 20th EPS methodology treats individual consumer behaviour as perfectly predictable day to day. 3. Because individual behaviour is aggregated into categories, the method is called Partial End Use Method. 4. The EPS excludes open-access consumers and railway traction from the listed categories of consumption. Which of the statements given above are correct?
15Consider the following statements: 1. The 20th Electric Power Survey observed that peak demand had grown faster than electrical energy requirement, suggesting a declining national load factor. 2. Load factor is irrelevant to electricity demand planning because only annual energy consumption matters. 3. The survey separately presents electrical energy requirement and peak demand in its long-term all-India summaries. 4. The survey treats electrical energy requirement and peak demand as identical measures. Which of the statements given above are correct?
