A single Ministry of Energy
Copy link to A single Ministry of EnergyPrelims and Mains
Coal, petroleum, power, and new and renewable energy each have their own ministry, and nuclear sits outside that structure with the Department of Atomic Energy. All five feed one grid, which takes solar at noon, hydro at the evening peak, nuclear for baseload, coal increasingly for flexibility, and gas turbines, batteries and pumped storage for balancing. An opinion piece argued that the five should be folded into one Ministry of Energy, since each optimises a fuel while nobody optimises the system.
- It would keep specialised departments for each fuel, but set strategy from one place.
- Integrated planning would then run across generation, fuel supply, transmission, storage and demand.
- The United States, Brazil, Saudi Arabia and the United Kingdom each have a unified energy ministry.
Today
- Renewable projects commissioned before transmission is ready
- Gas based plants built without assured fuel
- Coal production, imports, railway logistics and power demand moving on different paths
Counterpoints to one ministry
- It could become unwieldy
- Sector focus could be lost during the merger
- Electricity stays on the Concurrent List
- Much of distribution lies with the States
What changed
- Hybrid renewable energy project
- A plant that generates from more than one renewable source, usually solar and wind, on one site and through one grid connection.
- Curtailment
- Deliberately cutting a plant's output below what it could generate, because the grid cannot carry or absorb the electricity.
- Evacuate
- In the power sector, to carry electricity away from where it is generated to where it is consumed.
- Inverter based resource
- A generator such as solar or wind that reaches the grid through power electronics, and so gives none of the rotating inertia that coal and hydro turbines do.
- Power purchase agreement
- A long term contract under which a buyer, usually a distribution company, agrees to take a project's electricity at an agreed price.

A data centre is counted in megawatts rather than in floor space, because electricity is what it really consumes and what it must be given without a break.
