• NTT DATA and ENGIE have formed a multinational energy partnership covering renewable power procurement and data center expansion.
• Agreements are already in place across the UK, Germany and the Netherlands, supporting long-term low-carbon power access.
• A UK corporate PPA will supply NTT DATA data centers through September 2030 from an operational 24 MW wind farm in South Wales.

NTT DATA and ENGIE have formed a strategic partnership to secure renewable and low-carbon power for the continued expansion of AI and data center infrastructure.

The multinational agreement brings together NTT DATA’s digital infrastructure operations and ENGIE’s renewable energy capabilities. It will cover renewable energy procurement, power supply and integrated energy solutions across selected markets.

The companies have already signed working agreements in the UK, Germany and the Netherlands. The arrangement comes as data center operators face growing pressure to secure reliable power while limiting the emissions associated with rapid AI growth.

Renewable power supports AI expansion

NTT DATA is positioning long-term energy procurement as a core part of its global data center growth strategy.

The company said the partnership is intended to move beyond a conventional supplier relationship. Instead, it creates a longer-term framework for securing competitive renewable energy and other power solutions.

Energy availability has become a strategic issue for the data center industry. AI workloads require substantial computing capacity, while cloud adoption continues to increase infrastructure demand.

For operators, the challenge extends beyond securing enough electricity. They must also manage energy costs, grid constraints and corporate decarbonization commitments.

“AI is transforming every industry, and long-term success depends on ensuring that AI is sustainable,” said David Costa, Chief Sustainability Officer at NTT DATA, Inc. “Sustainability is both a competitive differentiator and a value creator. This partnership with ENGIE reflects our belief that energy transition and AI transformation must advance together, enabling us to innovate and scale responsibly while delivering long-term value for our clients and society.”

UK PPA runs through 2030

In the UK, NTT DATA has entered into a Corporate Power Purchase Agreement with ENGIE.

The agreement will supply NTT DATA data centers until September 2030. Electricity will come from an operational, RE100-compatible 24 MW wind farm in South Wales.

Long-term PPAs can provide data center operators with greater visibility over power supply and costs. They can also help companies make progress toward renewable electricity commitments as computing demand increases.

“This partnership gives us the energy foundation we need to keep pace with accelerating AI demand without compromising on our sustainability commitments,” said Doug Adams, CEO of NTT Global Data Centers. “Securing long-term access to renewable power at scale is one of the defining challenges for our industry right now, and working with a partner like ENGIE lets us continue our growth with confidence — for our clients, for our company and for the environment.”

The partnership also gives ENGIE a larger role in the fast-growing energy requirements of digital infrastructure.

Nicolas Lefèvre-Marton, Group Vice President Data Center Acceleration & Strategy Partnerships, ENGIE, said: “Our partnership with NTT DATA is an exciting synergy between our industries, with both parties working to address the energy requirements of the data and AI revolution with renewable and sustainable solutions.”

Energy strategy moves up the data center agenda

The agreement reflects a wider shift in how major technology companies approach energy procurement.

Power availability increasingly affects where companies can build data centers and how quickly new capacity can enter operation. Renewable procurement has therefore become closely connected with infrastructure planning, investment decisions and operational resilience.

For C-suite executives and investors, the issue is becoming both financial and environmental. Electricity costs can materially influence data center economics. At the same time, emissions associated with digital infrastructure face closer scrutiny as AI adoption accelerates.

Miya Paolucci, CEO 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 decarbonization ambitions.”

For NTT DATA, agreements across three European markets provide an early foundation for linking expansion with long-term energy planning.

The broader significance reaches beyond the two companies. As AI infrastructure scales globally, access to dependable low-carbon electricity is becoming a competitive constraint. Data center growth will increasingly depend on whether operators can align energy procurement, grid resilience and climate commitments within the same investment strategy.
