Summary

• NTT Data has signed a UK corporate power purchase agreement with Engie.
• The deal covers power from a 24MW wind farm in South Wales until September 2030.
• Working agreements in Germany and the Netherlands point to a wider European energy strategy for datacentre growth.

NTT Data has signed a corporate power purchase agreement with Engie for renewable power from a 24MW wind farm in South Wales, extending the link between AI demand, datacentre growth, and long-term energy procurement.

The UK agreement sits inside a broader partnership under which NTT Data will secure long-term access to Engie renewable energy and power solutions across selected priority markets. The companies have also signed working agreements in Germany and the Netherlands, although details of those arrangements have not been disclosed.

Under the UK cPPA, Engie will supply power from the South Wales wind farm until September 2030. The wider framework covers renewable energy procurement, power supply, and integrated energy solutions rather than a narrow supplier contract.

Miya Paolucci, chief executive of Engie UK, said: “This cPPA is the result of a deep understanding of NTT Data’s needs, demonstrating how a collaborative approach can deliver innovative solutions and sustainable infrastructure to support long-term growth and decarbonisation ambitions.”

The commercial logic is becoming stronger as AI changes datacentre demand. Operators need high-density compute capacity, but power availability, grid connection, renewable procurement, and local planning are now as decisive as property and fibre. A long-term PPA can help manage price exposure, support sustainability commitments, and provide a clearer energy story to customers and regulators.

David Costa, chief sustainability officer at NTT Data, connected the agreement directly to AI growth, saying: “AI is transforming every industry, and long-term success depends on ensuring that AI is sustainable.”

The geography matters. The UK, Germany, and the Netherlands are all significant datacentre markets with different grid constraints, renewable procurement structures, and planning pressures. A cross-market energy framework gives a large operator more room to align datacentre expansion with energy strategy, rather than treating power as a local procurement problem solved site by site.

There are limits to what a cPPA proves. It does not mean every workload runs directly on wind power at every moment, and datacentres still depend on the physical grid for continuous supply. Annual renewable procurement must therefore be understood alongside efficiency, storage, grid reinforcement, load flexibility, and actual emissions accounting.

Even so, the deal shows how digital infrastructure strategy is moving into energy markets. As AI workloads push electricity demand upwards, operators that can secure credible long-term power arrangements will have an advantage over those that assume capacity can be bought later. Compute ambitions are now constrained by electrons as much as by chips.
