Global Switch has signed an eight-year Power Purchase Agreement (PPA) with German renewable energy developer RWE in the UK.

The PPA will see the data center firm offtake around 70GWh of power per year from RWE’s Brechfa Forest West onshore wind farm in Wales. The PPA, which came into force this month, will be attributed to Global Switch’s London Docklands data center.

Commissioned in 2018 and comprising 28 turbines, the wind farm has a capacity of 57.4MW.

“Our agreement with RWE is a critical next step on our journey to purchasing 100 percent renewable energy by 2030, and to the setting of new standards for what a sustainable, environmentally-conscious data center can look like. 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,” said Peter Domeney, COO at Global Switch.

Global Switch’s Docklands data center has 224MVA of power available and hosts H100 and H200 GPUs for CoreWeave, in what Global Switch claims is Europe’s largest deployment of the Nvidia hardware.

The company operates two sites in the Docklands – London East and London North. It announced plans for a third facility, London South, which will offer 40MW across 27,000 sqm (290,625 sq ft) in 2024. In June of last year, it launched a showcase of liquid cooling technologies at the Docklands site.

RWE is one of the biggest suppliers of renewable energy in Europe. It has signed several PPAs with digital infrastructure firms over the past few years. The most recent being a ten-year PPA with Telehouse, signed last year.

It has also inked several PPAs within the US market with major hyperscalers, including Meta and Microsoft.
