By March 2025 there had already been three battery bank fires in the UK.
The UK’s renewable energy drive has created major issues for power distribution and energy security. Not only is there a requirement for massive changes to cable and substation infrastructure to distribute electricity from these distant sources, but because renewable power is intermittent and not very predictable it is now essential to install large electricity storage systems. This poses a significant and new safety problem.
Grid-scale lithium-ion battery energy storage systems can play a part in supporting short term grid flexibility – but they come with serious, and increasingly visible, risks. The UK is on course for a series of major battery storage-related incidents unless the government acts urgently.
A lithium-ion battery storage fire is unlike any other. When batteries go into thermal runaway, an uncontrollable, violent chain reaction phenomenon typically triggers fires and even explosions. Highly toxic and flammable gases are released and the millions of litres of water used by firefighters can result in contaminated firewater run-off. Fires can reignite days or even weeks later
Lithium-ion battery storage systems are now planned on an unprecedented scale. Many are heading for rural locations, alongside utility-scale solar schemes and very close to environmentally sensitive sites and residential areas, especially when near National Grid substations. According to trade figures, by the end of 2024, the UK had 7GWh of grid-scale battery energy storage online. But sector data suggests the current planning and construction pipeline in the UK is an astonishing 444GWh – that’s significantly more than the cumulative global capacity at the end of 2024
The enormous pipeline and pace of the lithium-ion battery storage rollout is driven by the current rush to deliver the energy transition. Developers in this fast-growing market are incentivised by the prospect of highly profitable energy arbitrage, and encouraged by a policy framework that heavily promotes and prioritises renewables infrastructure
This massive market push is not yet underpinned by a proper, legally-enforced government safety framework, despite the well known hazards and risks. Without action on regulations, standards and oversight, the hurried, mass-scale deployment of lithium-ion battery storage could become a ‘Grenfell’-style failure of the energy transition

What’s behind South Korea’s battery fire accidents?
A series of fires that occurred between 2017 and 2019 brought South Korea’s energy storage market to a standstill. New research seeks now to shed light on all the causes of the accidents and analyzes several social factors that may have led to the continuous occurrence of the accidents.

Proposal: Standard for Battery Energy Storage Systems (BESS) - by Richard Dunbar
July 2025
This document outlines a proposed draft standard for Battery Energy Storage Systems (BESS) currently in operation or under development across the United Kingdom. There is growing concern that existing UK regulations inadequately address the safety and environmental risks associated with BESS installations, especially in the context of government risk management policies. Numerous international incidents have demonstrated that BESS installations pose significant risks to human life, animal welfare, and the environment.
It is important to note that the enactment of the Regulatory Reform (Fire Safety) Order 2005 resulted in the repeal of numerous fire safety provisions, including locally enacted legislation that previously mandated fire authority consultation during planning applications. This shift has contributed to a systemic erosion of fire safety standards, as evidenced by investigations into major incidents such as the Grenfell Tower fire. These regulatory changes were ostensibly designed to streamline development but have had the effect of weakening public protections and undermining emergency service preparedness.
Richard Dunbar is the Managing Director of Park Lodge International Ltd, known for its expertise in fire investigation and emergency response training.
He previously served as Chief Fire Officer in Dar es Salaam, Tanzania, and Nairobi, Kenya, where he established comprehensive fire, rescue, and ambulance services based on UK standards.
He founded the International Vehicle Fire Investigation course, which has been running for over 25 years and is now delivered globally.
He co-authored the Energy Institute’s code of practice for recovering low flash products from road tankers and wrote several key texts, including the Police Blue Book on HAZMAT incidents and fire investigation handbooks.
His work spans Europe, Africa, and the Middle East, and he’s been involved in counter-terrorism exercises for the UK Foreign and Commonwealth Office.
In recent years, he’s focused on fire risks associated with alternative fuel vehicles, including electric vehicle fire investigation and safety protocols.
