We have worked to support renewables sector clients for many years and are currently employed by many clients in this sector with combined revenues in the billions.  If you are such a business or wish to enter the UK market please do contact us or request a call back to explore how we could work in partnership with you on safety matters in the UK.

Today the Health and Safety Executive have issued new guidance for those involved in grid-scale battery energy storage systems.  A copy of the safety advice can be viewed on the HSE website by clicking on this link: https://www.hse.gov.uk/electricity/battery-energy-storage-systems.htm

This summarises the responsibilities held by designers, installers and operators of these systems and also gives advice on other agencies who might be helpful or have specific requirements to place on any such project including Local Planning Authorities, DEFRA, Fire England and other Fire and Rescue Services and the Environment Agency.

The list of regulations that might apply is listed below.  Please note that the application of the Dangerous Substances and Explosive Atmospheres Regulations will depend on the particular design of the energy storage facility and that the use of lithium-ion batteries will also carry a linked risk from a localised fire and potential thermal runaway should a fire occur.

More information is presented below:

Health and safety responsibilities

If you design, install or operate BESS, you have a legal responsibility to comply with health and safety legislation, including:

If you comply with these regulations you will manage the health and safety risks of BESS.

Planning permission

Planning permission for BESS is a matter for local planning authorities. To find out if your project will need planning permission, contact your local planning authority (LPA) through your local council.

Each nation in Great Britain has its own responsibility for planning policy:

HSE has a limited role in the planning process. We should only be consulted by developers and local authorities on planning proposals that appear to fall within known consultation zones around:

  • major hazard establishments
  • major accident hazard pipelines
  • licensed explosives sites

Environmental protection

Environmental issues (including if a permit for emissions and discharges for BESS is required) are a matter for the following:

Notifying your fire and rescue service

Under the Dangerous Substances (Notification and Marking of Sites) Regulations, if you are an operator of a BESS site which holds 25 tonnes or more of dangerous substances, you must notify your local fire and rescue service to inform their emergency response planning.
