Global Switch Secures Major Wind Power Deal with RWE for AI-Ready London Data Centre

Global Switch Inks Eight-Year Wind PPA with RWE to Power AI Expansion January 23, 2026 In a significant move to secure low-carbon power for growing artificial intelligence workloads, data centre operator Global Switch has entered into an eight-year power purchase agreement (PPA) with German energy giant RWE. The deal underscores the intensifying focus on sustainable energy sourcing within the digital infrastructure sector, as soaring electricity demand from AI and digitalization tests grid capacities and corporate climate commitments. The agreement, commencing in January 2026 and running through 2033, will supply approximately 70 gigawatt-hours of renewable electricity annually to Global Switch's London Docklands campus. The power will be sourced from RWE's Brechfa Forest West onshore wind farm in southwest Wales, a 57.4-megawatt facility featuring 28 turbines that has been operational since 2018. This long-term contract is a key component of Global Switch's strategy to procure 100% renewable energy for its operations by 2030. Ulf Kerstin, Chief Commercial Officer of RWE Supply & Trading, highlighted the sector-wide trend driving such agreements. "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," Kerstin stated. "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." The London Docklands facility, situated in the capital's core business district with 224 Mega Volt Ampere of secured power, is undergoing densification and expansion to meet rising compute demands. The site's relevance for high-performance AI workloads was recently underscored by its selection by cloud provider CoreWeave to host a large-scale deployment of Nvidia H100 and H200 GPUs. Global Switch has also showcased advanced liquid cooling technologies at the location, including systems new to the European market, to address the thermal challenges of next-generation hardware. Beyond this PPA, Global Switch is pursuing ambitious efficiency targets, including an annualized power usage effectiveness (PUE) of 1.2 across its European portfolio. The company's emissions reduction goals received validation from the Science Based Targets initiative in 2025, and its sites participate in the European Code of Conduct for Energy Efficiency in Data Centres. For RWE, the UK's largest power generator, this deal exemplifies its strategy to leverage its global renewables portfolio and trading expertise to serve large-scale commercial customers. The company is investing billions to expand its generation capacity across offshore wind, onshore wind, solar, and battery storage, positioning itself to meet electricity demand growth linked to AI and broader electrification.
