Data Centres: Energy Demand

Earl Russell Excerpts

Thursday 16th April 2026 Lords Chamber

Asked by

[Earl Russell]

To ask His Majesty’s Government what steps they are taking to ensure that projected increases in energy demand from data centres do not compromise the achievement of their targets for clean power by 2030 and for net zero by 2050.

[The Minister of State, Department for Energy Security and Net Zero (Lord Whitehead) (Lab)]

My Lords, the Government recognise that Great British electricity demand is expected to grow significantly, driven in part by advances in AI. We are clear that this growth must not prevent delivery of clean power by 2030 and net zero by 2050. The Government are working to ensure data centre energy demand supports a flexible, resilient and increasingly low-carbon electricity system, including through smarter siting, improved use of existing clean generation and more efficient use of power. Importantly, evidence has shown that AI will support emissions reduction across the economy through improved efficiency and system optimisation, potentially outweighing additional electricity demand.

[Earl Russell (LD)]

My Lords, with Ofgem warning that proposed data centres are seeking 50 gigawatts, exceeding our current peak demand, my view is that, as yet, inadequate assessments have been made by government and regulators of AI’s climate impacts. Does the Minister agree that it is unacceptable merely to believe that this demand is compatible with clean power and our net-zero targets? I ask the Minister to commit to a NESO standing forecast for AI’s electricity use and to ongoing direct contact between government and the Climate Change Committee on data centres.

[Lord Whitehead (Lab)]

I completely agree with the noble Earl that merely believing that it is all going to be okay and that we can easily absorb all these additional demands on the energy sector without doing anything else is, at least, a folly. That is why the Government are taking substantial steps, for example through the AI growth zones, to make sure that we plan where data centres will be and make sure that those data centres are as closely aligned as possible with sources of either optimised electricity or constrained electricity or with new sources of energy production, so that the AI data centre development is not a burden on the system but an addition to it.
