Question to the Ministry of Defence:

To ask the Secretary of State for Defence, if he will publish guidance used by his Department for the a) construction and b) management of battery energy storages sites.

The Ministry of Defence is progressing its ‘Defence Advanced Battery Strategy’ which sets out the Department’s approach to advanced battery technologies.

The Department does not currently publish specific guidance for the construction or management of Battery Energy Storage Systems on its estate. This is a recognised gap, and a planned pilot project will inform future feasibility work and the development of appropriate standards and guidance in due course.
