Four gigawatts of grid access. Two point six gigawatts of dispatchable generation. A thousand acres beside one of Britain's largest substations.
That is what Drax Group put on the table this week, and it turned out to be worth more than the electricity its power station sells. On 3 November, Drax signed a strategic partnership with Brookfield and Brookfield's UK AI-infrastructure platform Radiant, backed by the Brookfield-Qai joint venture, to develop a data centre campus on the Drax Power Station estate in North Yorkshire. The target is more than 1 GW of compute capacity. The first phase is up to 100 MW, due to run from the first quarter of 2028. Brookfield puts total potential investment, chips included, above £20 billion ($26.8 billion), with £2.5 billion for Phase 1.
Investors read the signal fast. Drax shares rose about 9% in London, the best performance in a falling FTSE 250. The stock had been valued mostly on a biomass subsidy that expires in March 2031. By lunchtime it had a second story.
Will Gardiner, Drax's chief executive, framed the deal as site preservation. "We are proud to be partnering with leading AI infrastructure providers on this project which can help secure the long-term future of the site and protect hundreds of jobs," he said.
The scarce asset here is the connection, and Drax is renting it out.
What Drax actually sold

The site also carries 2.6 GW of active dispatchable generation and cooling systems. · Drax Group, 2026
Aggregate ambition across three phases
Phase 1 is 100 MW; Phase 2 adds 500 MW; Phase 3 is post-2031. · Drax Group, 2026
Including semiconductor chips
Brookfield's estimate; £2.5 billion is earmarked for the first phase. · Drax Group, 2026
Commercial operation targeted for Q1 2028
The first phase would import power directly from the grid, managed by Drax. · Drax Group, 2026
The estate is unusual because it already contains the expensive parts. It sits next to one of the country's largest substations and within reach of the UK fibre network. It has 4 GW of grid access, 2.6 GW of active dispatchable generation and existing cooling systems. Building that from a field in the Home Counties would take years and a queue position nobody can buy quickly.
The division of labour is straightforward. Drax supplies land, power integration and planning. Radiant runs design, customer engagement and commercialisation, and is meant to sign anchor customers before construction starts. Brookfield and Qai supply capital and operating capability through a joint venture announced in 2025. Qai is a subsidiary of the Qatar Investment Authority.
| Phase | Capacity | Power source | Timing |
|---|---|---|---|
| Phase 1 | Up to 100 MW | Direct grid import, managed by Drax | Operational Q1 2028 |
| Phase 2 | 500 MW | Behind-the-meter generation under a long-term PPA | 2028–2031 |
| Phase 3 | Additional capacity | Same behind-the-meter model | Post-2031 |

The subsidy clause doing the quiet work
Phase 1 is a grid customer. Phase 2 is something stranger: a data centre wired into a biomass plant.
In November 2025, Drax signed a Contract-for-Difference agreement with the UK government to provide about 6 TWh of biomass generation a year between April 2027 and March 2031. That is roughly 30% of the annual baseload output from its 2.6 GW of active generation. Buried in the agreement is a mechanism that lets Drax ask to use up to 500 MW of that capacity to power a data centre.
The permission is not automatic. It requires agreement with the government and the Low Carbon Contracts Company, and the decision has to weigh value for money for consumers, energy security and sustainability. Still, the clause changes what the asset can become. A subsidised generator with a fixed contract is a regulated cash flow. A generator that can route 500 MW into a private data centre is something closer to an infrastructure landlord.
JPMorgan analysts made the link explicit. The announcement, they wrote, could raise expectations that Drax Power Station continues operating beyond the expiry of its subsidy scheme in March 2031. That is the real bet inside the press release. The campus is the visible project; the extension of the plant's economic life is the prize.
Grid connection as the new land grab
Britain has more data-centre demand than it has places to plug in. More than 50 GW of data-centre capacity sits in the transmission queue. The government says the UK needs at least 6 GW of AI-capable capacity by 2030. The arithmetic explains why a 1,000-acre power station with an existing connection suddenly looks like prime real estate.
The policy backdrop arrived in the Autumn 2026 Budget. The Data Centre Covenant, part of the plan for five AI Growth Zones across England, Scotland and Wales, offers faster and more certain planning and grid access. In return, operators are expected to lower electricity bills, invest in local communities, meet environmental standards, create jobs and strengthen national security. Drax says its plan aligns with the Covenant's criteria. The first planning application is being prepared, and public consultation is expected to begin this month.
Queue position has become a balance-sheet item. As we wrote in October, PJM closed its data-centre fast lane one day after Voltus raised $225 million — a reminder that the rules around large-load interconnection can move faster than the projects they govern. That episode is the cautionary version. Drax is the lucky version: it already holds the connection.
The model is not unique to Drax. Across the US and Europe, generators with spare grid capacity are being repriced as AI infrastructure. What makes this deal notable is the size of the connection relative to the first phase. Drax is not starting with a pilot on a brownfield corner. It is starting with 100 MW and an option on a gigawatt.
The tenant is still missing
The announcement is a partnership to develop, not a commitment to build. Phase 1 is subject to planning approval, regulatory and network approvals, an acceptable tenant, the negotiation of commercial agreements and a final investment decision by each party. Radiant is supposed to secure anchor customer commitments before construction begins.
No tenant has been named. That matters more than the £20 billion headline. A 100 MW shell with no customer is an option on future demand, and options are cheap to announce and expensive to exercise. The first credible signal will be a named anchor tenant, not another rendering of the site.
If constructed in full, this project could become one of the largest data centres in the UK, with the potential to attract billions in inward investment, supporting the north's re-industrialisation and strengthening sovereign AI capability.— Will Gardiner, CEO, Drax Group
The conditional "if constructed in full" is doing a lot of work in that sentence. It is the difference between a land option and a data centre.
Planning consent and the public consultation that starts this month.
A named anchor tenant willing to commit before construction.
A final investment decision from Drax, Brookfield, Qai and Radiant.
There is a fourth gate for Phase 2, and it is political. The 500 MW behind-the-meter step needs the government and the Low Carbon Contracts Company to agree that diverting subsidised biomass capacity to a data centre is good value for consumers. That is a decision no engineering team can make.
What would make this real
The timeline is unusually specific for a project this early. Planning application in preparation. Public consultation in November 2026. Commercial operation from Q1 2028. Those dates are close enough to test. A planning application that slips into 2027 makes early 2028 hard. A tenant that signs in 2027 makes it plausible.
The capacity numbers are less informative than they look. The 4 GW is the site's connection, not the data centre's draw. The first phase uses up to 100 MW. The gigawatt target is the sum of three phases, two of which are ambitions rather than commitments. Read the ladder, not the top rung.
For the UK, the deal offers a template. Legacy generators with large connections can become AI landlords without building new transmission. That is faster than reinforcing the grid and politically easier than new pylons. It also concentrates risk on a handful of brownfield sites and on the willingness of regulators to let subsidised capacity serve private compute.
For Drax, the economics are cleaner than the politics. The company gets a second use for land and grid access it already owns, a partner with long-duration capital, and a story that extends the life of a plant whose subsidy ends in 2031. The shares moved about 9% on the announcement. That is the market pricing the socket.
What the £20 billion does not tell you
The £20 billion is an estimate, and it includes semiconductor chips. That single caveat changes how the number should be read. Chips are the most volatile line in any AI build, they depreciate faster than concrete, and their price depends on a supply chain none of the four partners controls.
The committed figure is smaller. Brookfield's £2.5 billion covers Phase 1. The remaining £17.5 billion is contingent on Phase 2, Phase 3, tenant demand and final investment decisions that have not been taken. The press release describes a ceiling, not a budget.
Divide the two numbers and the shape becomes clearer. Phase 1 works out to roughly £25 million per megawatt of capacity. The full gigawatt, at £20 billion, works out to about £20 million per megawatt, chips included. That is a rough comparison, not a valuation. It does suggest the later phases are expected to be cheaper per megawatt because they reuse the site, the connection and the cooling.
Four things are missing from the disclosure. There is no tenant. There is no power price for the behind-the-meter phase. There is no revenue share between Drax, Brookfield, Qai and Radiant. And there is no construction contract or procurement timetable. Those are the terms that will decide whether this is a data centre business or a land-option business with a press release.
The currency headline adds one more layer of confusion. The "$27 billion" figure is the £20 billion estimate converted at roughly 0.746 pounds to the dollar. The two numbers describe the same ceiling, not two separate commitments.
The CfD clause is the hinge for Phase 2. Without government sign-off, the campus stops at 100 MW.
The 2028 date depends on a tenant and a planning consent, neither of which exists yet.
The market has already priced the socket. The tenant, the planning consent and the CfD amendment are still unpriced.
