RWE has agreed an eight-year power purchase agreement to supply renewable electricity to Global Switch’s London Docklands data centre, sourcing the power from its Brechfa Forest West onshore wind farm in Wales, the companies said.
Under the agreement, which will run from January 2026 to 2033, RWE will provide about 70 gigawatt hours (GWh) of electricity a year. The power will come from the 57.4 megawatt Brechfa Forest West project, which was commissioned in 2018 and comprises 28 turbines.
RWE said the deal reflects rising demand for low-carbon electricity from energy-intensive digital infrastructure, as data centres expand to support cloud computing and artificial intelligence.
“In view of the ongoing digitalisation and the increasing use of artificial intelligence in almost all areas of life, the number of data centres and their energy requirements are growing,” said Ulf Kerstin, chief commercial officer at RWE Supply & Trading. “Some data centre operators are already relying on the use of low-carbon electricity from RWE, and we are delighted to have gained Global Switch as another partner.”
Global Switch said the agreement supports its goal of sourcing all of its electricity from renewable energy by the end of the decade. “Our agreement with RWE is a critical next step on our journey to purchasing 100% renewable energy by 2030, and to the setting of new standards for what a sustainable, environmentally-conscious data centre can look like,” said Peter Domeney, chief operating officer at Global Switch.
He added that the deal links renewable generation with advanced digital infrastructure. “It’s an agreement that brings together the forests of Wales and the most powerful, most advanced AI and high performance compute deployments in the world,” Domeney said.
Global Switch’s London Docklands campus has 224 MVA of secured power and is undergoing densification and expansion. Last year, the site was selected by U.S.-based cloud computing company CoreWeave to host one of Europe’s largest deployments of NVIDIA H100 and H200 graphics processing units, alongside liquid cooling systems.
Global Switch is targeting 100% renewable energy use and an annualised power usage efficiency of 1.2 across its European data centre portfolio by 2030. RWE said it continues to invest across offshore and onshore wind, solar and battery storage, alongside its power trading activities.
