Japanese tech firm NTT Data has partnered with Engie to power its data center portfolio with sustainable energy sources.

According to the companies, the partnership will see NTT secure long-term access to Engie’s renewable energy and power solutions. The partners claim that the deal goes beyond a traditional supplier relationship, establishing a long-term framework covering renewable energy procurement, power supply, and integrated energy solutions across select priority markets.

As part of the agreement, the companies signed a corporate Power Purchase Agreement (cPPA), under which Engie will supply power from a 24MW wind farm in South Wales until September 2030.

“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,” said  Miya Paolucci, CEO of Engie UK.

In addition, the companies revealed that they had also signed working agreements in Germany and the Netherlands. Specific details on these agreements have not been disclosed.

“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. ”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.”

Headquartered in Paris, France, Engie is one of the world’s largest renewable energy operators, with more than 57GW of total installed renewable and battery storage capacity. The company has signed numerous deals with data center firms to supply power and services.

Most recently, it expanded a carbon-free energy partnership with Google in Germany until 2030.
