NTT DATA (data center company) and ENGIE (energy company) have announced a strategic partnership aimed at securing long-term access to renewable and low-carbon energy to power the expansion of NTT DATA's global data center operations, with agreements already signed in the United Kingdom, Germany, and the Netherlands.

Partnership Scope and Structure

The collaboration, announced on July 29, 2026, is designed to move beyond a conventional supplier relationship. According to the companies, it establishes a long-term framework covering renewable energy procurement, power supply, and integrated energy solutions across select priority markets. The arrangement is intended to support NTT DATA's net-zero ambitions while enabling continued growth in AI, cloud and digital infrastructure services.

ENGIE, which employs more than 90,000 people across 30 countries and covers the full energy value chain from production to sales, will provide the energy foundation underpinning the agreement. NTT DATA, described as a more than USD 30 billion business and technology services company serving 75 percent of the Fortune Global 100, is seeking to address what both parties describe as one of the most critical challenges in the digital economy: securing reliable, competitive, and low-carbon energy at scale.

The partnership is structured as a multinational arrangement, with working agreements already executed in three European markets. Each of those agreements is intended to serve NTT DATA's data center footprint in the respective country as the company pursues what it describes as a global data center expansion strategy.

UK Wind Farm Deal Already Operational

The most concrete element of the partnership announced to date is a Corporate Power Purchase Agreement in the United Kingdom. Under this agreement, NTT DATA has secured power supply from a 24-megawatt wind farm located in South Wales.

The wind farm is described as RE100-compatible, meaning the electricity it generates meets the standards required by the RE100 initiative for renewable energy claims. The CPPA runs until September 2030, with supply already operational at the time of the announcement.

Miya Paolucci, CEO of ENGIE UK, said the agreement was the result of a deep understanding of NTT DATA's requirements. "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," she said.

AI Demand Driving Energy Strategy

Both companies framed the partnership explicitly around the accelerating energy demands generated by artificial intelligence infrastructure. Data centers supporting AI workloads require substantial and reliable power, and the ability to source that power from low-carbon sources has become a defining challenge for the industry.

Doug Adams, CEO of NTT Global Data Centers, said the partnership provides the energy foundation needed to keep pace with growing AI demand without sacrificing sustainability commitments.

"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," Adams said.

David Costa, Chief Sustainability Officer at NTT DATA, Inc., characterized the convergence of energy transition and AI transformation as inseparable strategic imperatives.

"AI is transforming every industry, and long-term success depends on ensuring that AI is sustainable," Costa said. "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."

ENGIE's Position in the Energy Transition

ENGIE's involvement in the deal reflects a broader push by the French energy company to position itself as a key enabler of the data center sector's transition to cleaner power.

Nicolas Lefèvre-Marton, Group Vice President for Data Center Acceleration and Strategy Partnerships at ENGIE, described the arrangement as an exciting synergy between two industries, both working to address the energy requirements of the data and AI revolution with renewable and sustainable solutions.

ENGIE reported a turnover of USD 81.9 billion in 2025 and invests an average of USD 13.67 billion per year in the energy transition. The company has set a net-zero carbon goal for 2045.

Its activities span renewable electricity and green gas production, flexibility assets including batteries, gas and electricity transmission and distribution networks, and local energy infrastructure such as heating and cooling networks. ENGIE is listed on the Paris and Brussels stock exchanges under the ticker ENGI and is included in indices such as the CAC 40 and Euronext 100.

Geographic Reach and Future Direction

While the UK wind farm agreement is the only deal with confirmed operational status at the time of the announcement, the partnership documentation confirms that agreements have been signed in Germany and the Netherlands as well.

The companies described the arrangement as covering select priority markets, suggesting the framework could extend further as NTT DATA continues its global data center expansion.

The partnership reflects a growing trend among large technology services providers to negotiate long-term energy contracts directly with renewable energy producers, bypassing traditional utility procurement in favor of dedicated supply arrangements that offer both cost certainty and verifiable sustainability credentials.
