Ofgem's regulatory review on data-centre power management
Published · Updated
What happened
Ofgem is actively considering power curtailment rules for data centres during grid stress to enhance electricity-system flexibility. This initiative aims to manage high energy demands at peak times, reflecting the growing concern over grid reliability as data centre operations expand. The consultation process is set to engage stakeholders in shaping these potential regulations.
Why it matters
This regulatory review signals a critical shift in managing energy demands from rapidly growing data centres, impacting future infrastructure investments and operational practices. It may redefine how flexibility is integrated into the electricity system, influencing energy procurement strategies.
Ofgem said on 17 June 2026 that it is considering rules that would allow or require data centres to reduce electricity consumption during periods of system stress. The move signals a concrete regulatory response to rising power demand from large digital loads and the need for additional demand-side flexibility. If advanced, the proposal could affect grid-connection terms, operating obligations and investment planning for major power users and the electricity system operator.
