Energy: Data Centres

The question

To ask the Secretary of State for Energy Security and Net Zero, what recent assessment he has made of the adequacy of the capacity of (a) energy suppliers and (b) the National Grid to provide power for the cooling systems for proposed new AI data centres.

Answered by Michael Shanks

The Department’s energy and emissions projections include growth in power demand from computing services such as data centres. However, to ensure a comprehensive view of the energy system, the methodology projects at a broader sector level, not disaggregating specific estimates for data centres.

The Capacity Market ensures supply meets demand. It operates by securing most of the required capacity four years in advance, with additional capacity secured one year ahead based on updated forecasts. This approach ensures Great Britain meets the Reliability Standard, which balances cost and reliability to maintain adequate electricity security.
