AI Datacentre in Lanarkshire to Rely Fully on National Grid 2026

The Lanarkshire AI datacentre project, a key part of the UK’s AI strategy, has confirmed it will be fully reliant on the National Grid, despite earlier claims it would be powered by renewable energy. DataVita, the company behind the massive development near Glasgow, had promised that the scheme would draw 1GW of power from green sources, but has now revised its plans.

The shift raises questions about the viability of renewable energy pledges in large-scale tech infrastructure and the future of Britain’s AI ambitions.

What Changed in the Lanarkshire AI Datacentre Plan?

DataVita initially stated that the Lanarkshire datacentre would be powered entirely by renewable energy, drawing 1GW – equivalent to the output of a small nuclear reactor or Britain’s largest windfarm. However, when the Guardian raised questions about the pledge, the company said the arrangement was “subject to final commercial agreements, planning, grid and consenting processes.”

Now, DataVita has quietly revised the plan, stating that the datacentres will be “fully grid served” with the possibility that solar and windfarms “could connect in the future.” The company maintains that the power drawn from the grid will be largely renewable energy.

This admission comes despite the project receiving £202m in public money from Britain’s national wealth fund in the form of wealth guarantees.

Why the Shift Matters for UK AI Strategy

The Lanarkshire project is a cornerstone of the UK’s AI strategy, which under former prime minister Keir Starmer aimed to build massive datacentres across the country. Developers were promised incentives to accelerate construction, with the expectation that these facilities would be powered by renewable energy.

The revised plan could present a problem for both DataVita and the government’s AI ambitions. The reliance on the National Grid, even if largely renewable, may undermine the green credentials of the project and raise concerns about the strain on the grid.

Furthermore, the public funding attached to the project means that taxpayers have a stake in its success. Any perceived backtracking on environmental commitments could lead to scrutiny and reputational risks.

What This Means for Renewable Energy Claims

The Lanarkshire case highlights the challenges of powering energy-intensive AI datacentres with renewable sources. While companies often pledge to use green energy, the reality of grid infrastructure and commercial agreements can complicate such promises.

DataVita’s revised plan suggests that connecting new renewable generation to the grid is not straightforward, and that datacentres may need to rely on the grid’s existing mix, which includes fossil fuels. The company’s statement that solar and windfarms “could connect in the future” indicates that renewable integration is a future aspiration rather than a current reality.

This situation is not unique to the UK; similar challenges are faced globally as the demand for AI computing power grows. For more on how renewable energy projects are progressing, see our coverage of Russia’s largest wind farm now fully operational in Dagestan.

The Role of Public Funding in AI Infrastructure

The £202m in wealth guarantees from the national wealth fund underscores the government’s commitment to positioning the UK as an AI leader. However, such funding comes with expectations of accountability and transparency.

When public money is involved, companies are under greater pressure to deliver on their promises, including environmental commitments. The revision of the renewables pledge could prompt questions about how the funding is being used and whether the project will meet its stated goals.

What to Watch Next

The Lanarkshire datacentre is still in development, and it remains to be seen how the grid connection will be finalized. Key things to watch include:

• Whether DataVita secures additional renewable energy sources in the future.
• How the National Grid manages the increased demand from the datacentre.
• The response from government and regulators regarding the revised plan.
• Any impact on the UK’s broader AI strategy and other planned datacentres.
• Whether public funding conditions are renegotiated.

As the project moves forward, stakeholders will be looking for clarity on how the datacentre will be powered and whether the green claims can be substantiated.
