Q1Consider the following statements: 1. Lithium-ion batteries store and release energy through the movement of lithium ions between electrodes. 2. Megawatt-hour is a unit of battery voltage, not of stored energy. 3. A battery with a 60 MW power rating can provide at most 60 MW instantaneously, though the duration depends on its energy capacity. Which of the statements given above are correct?
Statement 1 is true: lithium ions move between electrodes during charge and discharge. Statement 2 is false because megawatt-hour measures energy capacity. Statement 3 is true: power rating limits instantaneous output, while energy capacity determines how long that output can last.
Q2Consider the following statements: 1. Green hydrogen can be produced by using electricity to split water into hydrogen and oxygen in an electrolyzer. 2. An electrolyzer in a green-hydrogen plant is a wind turbine used to convert wind energy into mechanical energy. 3. Renewable electricity that might otherwise be curtailed can be used to produce hydrogen through electrolysis. Which of the statements given above are correct?
Statement 1 is true: electrolysis uses electricity to split water into hydrogen and oxygen. Statement 2 is false: the electrolyzer is the device that splits water, not a wind turbine. Statement 3 is true: excess renewable electricity can be routed to hydrogen production instead of being curtailed.
Q3Consider the following statements: 1. In the grid-connected rooftop solar programme, central financial assistance or subsidy is provided to residential electricity consumers under Component-A. 2. The same rooftop solar programme provides incentives to distribution companies under Component-B. 3. Under the national-portal mechanism, applicable financial assistance is transferred directly to the empanelled vendor before installation and verification. 4. A residential consumer can apply either through the National Portal for Rooftop Solar or through the State distribution-company portal. Which of the statements given above are correct?
Statements 1 and 2 are correct: the programme provides CFA/subsidy to residential consumers under Component-A and incentives to distribution companies under Component-B. Statement 3 is incorrect because under the national-portal mechanism the CFA is transferred directly to the consumer account after installation and verification. Statement 4 is correct: the two application routes are the National Portal and the State DISCOM portal.
Q4Consider the following statements about green corridors and renewable evacuation: 1. Scattered solar projects can require separate transmission lines to the nearest substation. 2. Green Energy Corridor planning emerged because power evacuation and nearby transmission infrastructure at potential renewable sites were found inadequate. 3. Green Energy Corridor infrastructure is meant only for rooftop solar systems, not large-scale solar and wind plants. 4. State transmission plans under the Green Energy Corridor process were submitted to the Central Electricity Authority for appraisal. Which of the statements given above are correct?
Statement 1 is correct: MNRE notes the extra transmission burden of scattered solar projects. Statement 2 is correct: MNRE says dedicated transmission was planned after inadequate evacuation and nearby transmission infrastructure were found. Statement 3 is incorrect because the source refers to large-scale solar and wind power plants. Statement 4 is correct: states submitted transmission plans to CEA for appraisal.
Q5Consider the following statements about green hydrogen: 1. Green hydrogen can be produced through electrolysis using electricity from renewable sources such as solar, wind or hydropower. 2. Electrolysis splits water into hydrogen and oxygen. 3. MNRE describes coal gasification as the only clean and sustainable method for green hydrogen production. 4. Biomass gasification is also mentioned as a method of producing green hydrogen. Which of the statements given above are correct?
Statements 1, 2 and 4 are correct. Green hydrogen can be produced by electrolysis powered by renewable electricity; this process splits water into hydrogen and oxygen. Biomass gasification is another production route. Statement 3 is false because coal gasification is neither identified as the only method nor substituted for biomass gasification.

Which of the statements given above are correct?
8Consider the following statements about the Solar Park model: 1. Solar parks address delays faced by individual developers in land acquisition, clearances and permissions. 2. The scheme's objective is to facilitate solar project developers to set up projects expeditiously. 3. It is primarily a scheme for installing individual off-grid solar pumps of up to 7.5 HP. 4. It is conceptually closer to common enabling infrastructure for utility-scale solar than to a household appliance subsidy. Which of the statements given above are correct?
9Consider the following statements: 1. Distributed energy resources are small-scale power generation or storage technologies that can be spread across an area. 2. Rooftop solar panels and backup batteries can be examples of distributed energy resources. 3.

10Consider the following statements about Intra-State Green Energy Corridor Phase-II: 1. The scheme is implemented by the respective State Transmission Utilities. 2. Rajasthan is among the states listed for implementation of the scheme. 3. The scheme is only for setting up renewable generation plants and not transmission lines or substations. 4. The scheme facilitates integration of renewable generation capacity. Which of the statements given above are correct?
11Consider the following statements about smart-grid infrastructure: 1. Smart-grid technologies use two-way communication technologies, control systems and computer processing. 2. Phasor Measurement Units can help operators assess grid stability. 3. Smart grids exclude batteries because storage is not part of grid modernization. Which of the statements given above are correct?
12Consider the following statements about the funding and physical scope of Intra-State Green Energy Corridors: 1. GEC Phase-I uses a funding mechanism of 40% Central Financial Assistance from MNRE, 40% KfW loan and 20% STU equity. 2. GEC Phase-II uses a funding mechanism of 33% Central Financial Assistance from MNRE and 67% to be arranged by STUs. 3. Phase-II's physical scope is smaller than Phase-I on both transmission-line length and substation capacity. 4. Phase-I is for about 24 GW renewable integration, while Phase-II is for about 20 GW renewable generation capacity. Which of the statements given above are correct?
13Consider the following statements about the PLI scheme for high-efficiency solar PV modules: 1. The scheme aims to reduce import dependence in renewable energy by building an ecosystem for manufacturing high-efficiency solar PV modules in India. 2. The scheme is technology agnostic and allows all technologies, while incentivising better module performance. 3. The scheme discourages integrated plants because quality control is outside its scope. Which of the statements given above are correct?
