Solar Power: Batteries

Asked by Pippa HeylingsLiberal DemocratDepartment for Energy Security and Net ZeroTabled Answered 10 June 2025UIN 56445

The question

To ask the Secretary of State for Energy Security and Net Zero, whether the 2035 Future Energy Scenarios-derived capacity ranges for solar and batteries in his Department’s Clean Power Action Plan connections annex are intended to be used by Ofgem and network operators as (a) technology caps and (b) interim indications.

Answered by Michael Shanks

The 2035 capacity ranges present credible pathways to decarbonise our energy system and provide certainty to investors by ensuring a 10-year horizon for connection offers. NESO will use the ranges to underpin connection offers out to 2035. The 2035 figures are interim, to enable connection reform to proceed at pace, and are subject to updates through the Strategic Spatial Energy Plan, which will be published in 2026.
