Renewable projects near the international border
Copy link to Renewable projects near the international borderPrelims and Mains
The Home Ministry has fixed how close to a frontier a renewable plant may stand. Solar, wind and hybrid renewable energy projects are barred within 1 km of the international border, the Line of Control and the Line of Actual Control.
- A project 1 km to 20 km out needs a No Objection Certificate from the Defence Ministry.
- Any project within 50 km needs Home Ministry security clearance.
- Staff from Pakistan, Bangladesh or China, and any land transfer to a foreign firm, need approval.
What changed
Green Energy Corridor
Copy link to Green Energy CorridorPrelims and Mains
- Evacuate
- In the power sector, to carry electricity away from where it is generated to where it is consumed.
Transmission is congested, so power from renewable rich States cannot reach the buyers who want it. The Green Energy Corridor is the programme that builds the lines to evacuate it, in intra-State and inter-State phases.
- The third phase of the intra-State corridor is in its final stages and has gone to the Union Cabinet for approval.
- The expected outlay is over ₹50,000 crore, and it would carry about 135 GW of renewable power out of the States that generate it.
- Right of way disputes and forest clearances have delayed the earlier phases, as have restrictions on overhead lines meant to protect the Great Indian Bustard.
What changed
- Baseload
- The minimum demand a grid carries round the clock, met by plants running steadily, such as nuclear.
- Department of Atomic Energy
- India's atomic energy establishment, which is not a ministry: it works directly under the Prime Minister.
- Curtailment
- Deliberately cutting a plant's output below what it could generate, because the grid cannot carry or absorb the electricity.
- 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.
