Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what steps his Department is taking to help ensure investment in the national grid, including batteries and other upgrades to capacity.

Government is working with delivery partners to speed up delivery of network infrastructure and increase grid capacity through reforms to planning, support for communities and strategic network design.

Ofgem is responsible for incentivising investment in electricity networks to achieve government strategic priorities, whilst ensuring it delivers value to consumers. Ofgem anticipates £71bn of investment in GB's electricity transmission networks between 2026-2031 as part of their RIIO-ET3 price control.

Government has set out plans for deploying battery storage in the Clean Power 2030 Action Plan and Clean Flexibility Roadmap. As of May 2026, GB has 7.3GW of grid-scale batteries, with ambition for 23–27GW by 2030. A further 17GW has Capacity Market agreements, and around 57GW has planning permission.
