Detail of outcome

The government response confirms that we will ensure the deployment of sufficient large-scale, long-duration electricity storage (LLES) to balance the overall system by developing appropriate policy to enable investment by 2024.

We will evaluate different policies, their benefits and their interactions with the energy system, and work with Ofgem to develop the appropriate policy.

See the related Benefits of long-duration electricity storage research which provides greater insight into the role that such storage could provide for the system.

We received 66 responses primarily from:

• developers
• investors
• trade associations
• asset owners
• academics

The majority of respondents agreed that LLES technologies face barriers to deployment. While most said that there is a need for government intervention to support these technologies, a few respondents did not see the need for LLES-specific support.

Original call for evidence

Summary

We're seeking evidence about barriers to the deployment of large-scale and long-duration electricity storage, and on different approaches for supporting the deployment of these technologies.

This call for evidence ran from
10am on 20 July 2021 to 11:45pm on 28 September 2021

Call for evidence description

Large-scale and long-duration electricity storage could provide an important role in decarbonising our energy system, for example by storing renewable power and discharging it over periods of low wind. However there is evidence that it faces market challenges that mean it may struggle to deploy at scale.

This call for evidence seeks information to help us understand in more detail:

• the barriers within the current market
• how these might be addressed
• the risks that may be associated with potential interventions to support the deployment of large-scale and long-duration electricity storage

See the related Smart Systems and Flexibility Plan which sets out how we can enable a smart, flexible, decarbonised energy system.

See the BEIS consultation privacy notice.

Please do not send responses by post to the department at the moment as we may not be able to access them.
