Longer duration storage can support a future energy system with high proportions of renewable energy by providing flexible energy supply and demand, and increasing the resilience of energy networks.
Deployment will also depend on ongoing developments in energy markets and a better understanding and communication of the risks. The Government will implement a policy on longer duration energy storage by 2024.

Energy National Policy Statements provide planning guidance for developers of nationally significant energy infrastructure projects. The energy National Policy Statements cover: The guidance makes it easier for decision makers, applicants and the wider public to understand: The 2023 revised NPSs (EN-1 to EN-5) came into force on 17 January 2024.
2.9.9 Electricity storage is essential for a net zero energy system, it stores electricity when it is abundant for periods when it is scarce, as well as providing a range of services to help maintain the resilience and stability of the grid.
1.1.5 This National Policy Statement (NPS), taken together with the Overarching National Policy Statement for Energy (EN-1), provides the primary policy for decisions by the Secretary of State on applications they receive for nationally significant renewable energy infrastructure defined at Section 1.6 of this NPS.
Long Duration Electricity Storage would reduce costs to consumers through lowering their energy bills, by avoided electricity grid reinforcement and avoided peak generational plant build. LCP's modelling estimates savings for the energy system (and ultimately the energy consumer) of up to £24 billion by 2050.
