Battery Energy Storage Sites: Safety Regulations

Debate between John Milne and Caroline Nokes

Thursday 5th June 2025 Commons Chamber

[Madam Deputy Speaker (Caroline Nokes)]

This is a subject in which I might have more than a passing interest.

[John Milne (Horsham) (LD)]

I beg to move,

That this House recognises the unique challenges posed by lithium-ion fires in battery energy storage sites; and calls on the Government to bring forward enforceable national regulations for their design and construction.

I have asked for this debate in order to highlight important issues associated with lithium-ion batteries when deployed at grid scale. These installations are known as battery energy storage systems, or BESSs. In particular, I am calling for clear national regulations that could be applied in the same way in every part of the UK. We need legislation, and I hope that this debate will push the Government further along the road to passing it.

The UK has set a target to achieve net zero emissions by 2050. To achieve that, many wind and solar farms have been constructed and permissions are being sought for many more. I fully support the drive towards renewable energy; the enhanced regulation that I am suggesting today is intended to secure the industry’s future, not to create more obstacles. I think it is perfectly possible to draw up regulations that will not stand in the way of BESS roll-out, and which in the long term could actually save the industry from a wholly avoidable setback in the event of an accident.

BESSs solve the classic question of what to do when the sun don’t shine and the wind don’t blow. They provide a number of highly useful functions, including load balancing, peak shaving and energy arbitrage. Above all, they make it practical to meet a much larger percentage of our national energy needs from renewables. However, every energy system carries some kind of risk, and most BESSs currently use lithium-ion battery technology. In the event of an accident—and sooner or later there are always accidents—lithium-ion batteries catch fire in a different way from other materials, in a process known as thermal runaway. It is important to note that most BESSs now rely on lithium iron phosphate or LFP batteries. This chemistry is much more stable than lithium nickel manganese cobalt oxide or NMC cells, which are common in consumer uses. That means fewer incidents, but those incidents can still be dangerous. In the future, there will undoubtedly be other chemistries, so we need to leave space for innovation.

Thermal runaway generates very high temperatures and requires different firefighting methods. It is usually best not to try to put out the fire, but rather to control the spread. Firefighters also have to contend with severely toxic gas emissions, the risk of an explosion, soil contamination and damage to watercourses. To repeat, I am in no way suggesting that battery energy storage systems are inherently unsafe. The risks they entail may be different from those of traditional systems, but they are perfectly controllable.

Public Authorities (Fraud, Error and Recovery) Bill

Debate between John Milne and Caroline Nokes

Report stage & 3rd reading
Tuesday 29th April 2025 Commons Chamber

[Madam Deputy Speaker (Caroline Nokes)]

I shall impose, with immediate effect, a four-minute time limit.

[John Milne (Horsham) (LD)]

When it comes to public money, everyone accepts the importance of preventing fraud; there is no dispute about that. The mere thought that our benefit system could be exploited loosens the cement holding our welfare system together. However, if we look back in history, there has been a track record of fraud recovery measures not delivering what was hoped. This measure will also probably never save the £1.5 billion that is expected of it, so I ask: will the alleged rewards of this legislation ever match the scale of the imposition on our civil liberties, and are we really going after the right targets?

We all want to catch deliberate and professional fraudsters, but they are precisely the people who are astute enough to change tactics, set up separate bank accounts, and avoid suspicion. Instead, it will be the innocent and the accidental claimants who fall into the trap. The implicit assumption is that we should trust in the DWP as a completely error-free organisation across the entirety of its massive operation. But the DWP does make mistakes. It makes mistakes all the time. And even when it knows that it has made a mistake, and it has been told so, it is very capable of making the same mistake all over again.

In my constituency of Horsham, Anthony and his husband were accused of providing misinformation to the DWP and were overpaid £10,000 as a result. Anthony protested without success. After a long fight the case went to appeal. The tribunal wasted no time deciding in his favour—it was an open and shut case. But then, earlier this year, Anthony and his husband were migrated over to universal credit. After confirming all details were correct, the DWP overpaid them again, and then sought to claw the money back over the following months. The DWP’s mistake, but Anthony pays the penalty.

The DWP has its rules, but real life does not run in straight lines. Real life is messy. How can we possibly rely on the DWP to mark its own homework when we know that there are just four fraud advisers per regional office to handle cases flagged by frontline staff?

Yes, there are some checks and balances within this legislation, but what is really needed is a profound cultural change within the DWP, and that is much harder to achieve. The common experience of people who have to deal with the DWP on a daily basis is that they feel that it is always looking to catch them out. Years and years of inflammatory rhetoric under a succession of Conservative Governments have convinced people to regard the DWP as their enemy, not their friend. If anything, the Bill digs that hole a little deeper.

What concerns me most about the Bill is its extreme overconfidence. It assumes that Government agencies always get things right and that individual citizens are to be automatically treated as objects of suspicion. In Committee, the Government were resistant to any amendments except their own, so I very much hope that they will reconsider today and accept the Liberal Democrat amendments.
