Batteries: Storage
The question
To ask the Secretary of State for Energy Security and Net Zero, whether he plans to provide information to communities affected by battery energy storage sites on the safety of those sites.
Answered by Michael Shanks
Communities near potential grid-scale battery sites should be informed about them via planning law, which requires local planning authorities to notify neighbours regarding planning applications either by site notice or letter, and to publish information about the application on a website. This provides the local community the opportunity to make representations about the application
The government has published guidance on existing battery safety standards.[1] Separately, the Health and Safety Executive has published guidance[2] for battery duty-holders under health and safety law. While intended for developers, communities may find this information helpful in gaining assurance that appropriate standards are in place for batteries.
In GB, fires at battery sites are rare and are mitigated by a regulatory framework overseen by the Health and Safety Executive. The latest available 5-year annual average fire incidence rate for GB batteries is 0.7% (2020/21 to 2024 to 2025)[1], lower than for wider non-domestic building fires in England at 0.8% (2019/20 to 2023/24)[2].
