Long Duration Electricity Storage

Closes 5 Mar 2024

Opened 9 Jan 2024

Overview

Long duration storage (LDES) is a key enabler to a secure, cost-effective and low carbon energy system. LDES can help to decarbonise the system by storing excess renewable generation over longer periods of time (days, weeks, and months), replacing flexibility from fossil fuelled generation and helping to alleviate constraints on the grid.

In the Government response to the Call for Evidence, published in August 2022, we concluded that LDES technologies have an important role to play in achieving net zero. It also recognised that these technologies face significant barriers to deployment under the current market framework due to their high upfront costs and a lack of forecastable revenue streams. 

The Powering Up Britain plan stated we will put in place an appropriate policy framework by 2024 to enable investment in LDES, with the goal of deploying sufficient storage capacity to balance the overall system. 

This consultation is setting out our proposal to introduce a cap and floor scheme for LDES and seeking views on several elements of our approach, including the eligibility criteria, the design considerations and our proposed options for delivering the scheme.
