Question to the Department for Energy Security & Net Zero:
To ask His Majesty's Government what steps they are taking to stimulate private investment in support of expansion of UK long duration energy storage infrastructure.
Answered by
Baroness Curran
Parliamentary Under-Secretary of State (Department for Energy Security and Net Zero)
The government is supporting private investment in long duration electricity storage (LDES) through the LDES cap and floor policy, which is being delivered by Ofgem. This will deliver the first LDES projects in Great Britain for over four decades.
On 26 June 2026, Ofgem published minded-to decisions for the first LDES application window, supporting 16 projects totalling 7.6GW of power and 137GWh of storage capacity.
The government’s Clean Flexibility Roadmap Update of 13 July 2026 contains further details on steps to deliver LDES, as well as other forms of energy storage such as hydrogen storage and power.
