Question to the Department for Energy Security & Net Zero:

To ask His Majesty's Government how much additional grid capacity is needed to handle 100 per cent renewable and nuclear electricity generation at current demand levels.

The Government keeps any need for additional grid capacity for our future electricity system under constant review. The National Energy System Operator’s network planning considers both how electricity generation and electricity demand are expected to develop over time, rather than planning the network solely on the basis of current demand. The Government is accelerating the expansion and modernisation of the electricity network, driving reforms across strategic network planning, connections, and planning and consenting, alongside measures to make more efficient use of existing network capacity.
