Why battery storage safety matters
Grid-scale battery energy storage systems (BESS) are becoming more common as renewable energy use increases. These systems play a vital role in balancing the grid — but they also come with health and safety risks that must be carefully managed.
New HSE guidance published
The Health and Safety Executive (HSE) has released updated safety guidance to help stakeholders comply with the law and reduce risks across the full lifecycle of battery storage systems.
You can read the full guidance on the HSE website.
Who is the guidance for?
The new document outlines legal duties and responsibilities for those involved in the design, installation, operation and regulation of BESS, including:
- Designers: Ensuring systems are planned and specified with appropriate safety controls
- Installers: Applying safe installation practices and verifying safety-critical elements
- Operators: Managing systems to prevent fire, thermal runaway, or environmental hazards
- Health and Safety Professionals: Ensuring systems comply with legislation and best practice
Key points from the guidance
- Clarifies which health and safety laws apply at each stage of the BESS lifecycle
- Outlines HSE’s role as a regulator and what they expect from dutyholders
- Highlights the need to notify your local fire and rescue service if the site will store 25 tonnes or more of dangerous substances
- Links to planning and environmental considerations from other regulatory bodies
