Software giant Microsoft is to source 90MW of electricity from the over 731MW Borssele 3&4 offshore wind farm off the coast of the Netherlands.
The 15-year deal starts in 2022 and will see power from the project go to Microsoft data centres.
Microsoft said the contract is with Eneco, which is part of the Blauwwind consortium developing the wind farm.
Eneco chief customer officer Hans Peters said: “Tech companies are facing the challenge to reduce their carbon footprints, mostly due to the vast energy consumption of their data centres.
“A global frontrunner like Microsoft does not see this as a challenge, but as an opportunity to boost the energy transition.
“We are proud we can help them switch to a sustainable, smart and clean energy supply in the Netherlands.
“As a result, Microsoft is creating local opportunity, growth and impact while enabling Eneco to continue to invest in large-scale renewable energy projects like Borssele 3&4.”
Microsoft energy and sustainability general manager Brian Janous said: “Our purchasing of renewable energy helps improve the sustainability of our operations and local grids.
“This agreement is our 14th renewable energy power purchase agreement and brings our total clean energy portfolio to more than 1.5GW.
“The electricity generated will help support the continued long-term growth of Microsoft cloud services delivered from the Netherlands, which is one of 54 Azure regions announced and part of one of the largest and most innovative cloud infrastructures in the world.”
The power purchase agreement is a next step in the ongoing partnership between Eneco and Microsoft.
In 2018, Eneco selected Microsoft as its preferred partner for cloud services, signing a three-year deal with Microsoft Azure, which enables the former to achieve its goals and ambitions in the area of digital transformation.
Borssele 3&4 will feature 77 MHI Vestas V164 9.5MW turbines.
Blauwwind also comprises Partners Group, Shell, Diamond Generating Europe and Van Oord.
