On a patch of Teesside land once shaped by the heavy industry that defined northern England, National Grid has agreed to buy nearly 30 hectares to raise Britain's largest electricity substation. The reason is an old and plain one: a new machine economy needs power before it can be built, and whoever can deliver that power first will attract the investment. Behind the engineering lies a deeper question the country has not yet answered, which is who will share in the benefits and who will live beside the consequences.
National Grid Moves to Build UK's Biggest Substation on Teesside to Power AI Datacentre
Britain's biggest substation, built for a datacentre that isn't yet approved
Mark
So what actually happened here? A land deal?
Mimi
Yes. National Grid agreed to buy 29.5 hectares at Dorman Point, on Teesworks land, to build what would be Britain's biggest substation. It's meant to feed a large AI datacentre planned next door.
Mark
Why does the mayor keep talking about speed?
Mimi
Ben Houchen says the hardest part of building a datacentre here is getting power to the site quickly. He says other countries have moved faster and taken the investment, and that up to 3.2GW on Teesside lets the region compete.
Luke
Worth flagging that the 3.2GW figure comes from Houchen, quoted by Sky News. The reporting doesn't say what National Grid itself has committed to, or when it would be switched on.
Mark
And the datacentre itself is confirmed?
Luke
Not fully. The source says the government was reported to have picked Teesworks last year, and that planning applications have been submitted. Submitted isn't approved.
Mimi
Right, and the substation is a step toward it. Matt Pearce talked about progressing as quickly as possible, but gave no timetable.
Mark
Is there a public reaction?
Mimi
Not in Teesside specifically, in this reporting. But there are protests elsewhere, from Auchtertool near Edinburgh to Brick Lane in London, and AI firms reportedly told ministers they had 12 months to head off opposition.
Luke
Also, Balfour Beatty is only reported to be in line for the work, and neither it nor Steel River Power had commented. That's still unconfirmed.
O Pulso
- National Grid has committed to buying 29.5 hectares at Dorman Point, a race now underway to deliver Britain's biggest substation before rivals take the investment.
- Local mayors and Whitehall are framing a single power connection as the difference between competing for AI datacentres and watching them go to Texas or Abu Dhabi.
- Campaigners in towns from Auchtertool to Brick Lane are pushing back against datacentres, and industry insiders have reportedly been given only about a year to quiet that opposition.
- Balfour Beatty and Steel River Power are being lined up to build and deliver the project, with planning applications for a near 500,000 square metre facility still pending.
- The land deal is a first step, and the speed of the power connection now depends on planning decisions and whether host communities accept what is built next door.
On a patch of Teesside land once shaped by the heavy industry that defined northern England, National Grid has agreed to buy nearly 30 hectares to raise Britain's largest electricity substation. The reason is an old and plain one: a new machine economy needs power before it can be built, and whoever can deliver that power first will attract the investment. Behind the engineering lies a deeper question the country has not yet answered, which is who will share in the benefits and who will live beside the consequences.
Last week National Grid agreed to buy 29.5 hectares, about 73 acres, of land at Dorman Point on Teesside, part of a site owned by the local partnership Teesworks. The company plans to build Britain's biggest electricity substation there, and it is meant to feed a large AI datacentre that planning applications describe at nearly 500,000 square metres.
National Grid's land chief said the deal reflects constructive work across partners and will support the growth of AI and digital industries in the region. Ben Houchen, mayor of the Tees Valley, made the case in starker terms. The biggest obstacle to building a datacentre in Britain, he said, is getting enough power to a site quickly, and while the US, the Gulf and parts of Europe have moved ahead, Teesside now has up to 3.2GW to offer. He added that if Britain wants AI capacity with sensitive data kept on British soil, it needs somewhere to put it.
The government is making a similar argument nationally, with a draft policy statement calling datacentres as fundamental to the economy as railways and electricity networks. It also insists that host communities must benefit, a claim that is far from settled. Opposition has grown in places as far apart as Auchtertool and Brick Lane, and the Guardian has reported that AI companies were warned they had a year to head off protests.
Balfour Beatty is reportedly set to build the substation and Steel River Power is heavily involved, though neither had responded to requests for comment. The land purchase is only a beginning. Planning decisions and the reaction of local people will determine how soon the power flows and whether Teesside is willing to live with what rises beside it.
Last week, National Grid agreed to buy 29.5 hectares, about 73 acres, of land at Dorman Point on Teesside. The land sits on a site owned by Teesworks, a local private-public partnership, and the company intends to build Britain's biggest electricity substation there. Sky News first reported the deal.
The purchase follows reports last year that the UK government had picked Teesworks as the location for a new artificial intelligence datacentre. Planning applications have been submitted for a project that would cover nearly 500,000 square metres. The substation is meant to supply power to that neighbouring facility.
Matt Pearce, National Grid's head of land, said the agreement reflects constructive work among everyone involved in enabling the infrastructure. He said it will support the growth of AI and digital technologies and the next phase of industrial and economic development in the region. He added that the company is committed to working closely with its partners to progress the development as quickly as possible.
Ben Houchen, the mayor of the Tees Valley combined authority, framed the deal around speed. He told Sky News that everyone who has tried to build a datacentre in the country knows the biggest problem is getting enough power to a site quickly. While Britain has been stuck in the queue, he said, the US, the Gulf and parts of Europe have pressed ahead and taken the investment. Having up to 3.2GW of capacity on Teesside, he argued, means the area can finally compete for such projects. He also said that if Britain wants its own AI capability, with sensitive data stored on British soil, it needs a physical place to put it, and he would rather that were Teesside than Texas or Abu Dhabi.
The government has been making a similar case in national terms. Last week it published a draft national policy statement on datacentres, describing them as as fundamental to the economy as the railways and electricity networks the country has long depended on. The statement said the country must take control over how datacentres are developed and make sure that the nation and host communities benefit from them.
That last point is contested. The rapid spread of datacentres in the UK has met strong opposition, with campaign groups protesting against planned developments in places as different as Auchtertool, a village north of Edinburgh, and Brick Lane in east London. In October, the Guardian reported that AI companies had told ministers they had 12 months to head off public opposition or risk US-style protests that could threaten construction.
On delivery, the London-listed infrastructure services group Balfour Beatty was reported to be in line to build the Teesworks substation for National Grid. The utilities firm Steel River Power is also heavily involved in the project. Both Balfour Beatty and SRP were approached for comment.
The land purchase is a step, not a finish line. The datacentre's planning applications and the wider policy statement will determine how quickly the power can be used, and whether host communities accept what is built beside them.
