Record Notes
Digital Realty is significantly expanding its UK footprint with a $2 billion "Mega-Campus" project designed to meet the high-density power demands of AI and hyperscale workloads. The campus is projected to reach a total capacity exceeding 300 megawatts (MW) upon full buildout, with initial phases focusing on AI-ready infrastructure capable of supporting liquid cooling and massive power densities.
A key feature of the campus is its integration of hydrogen fuel cell technology, being piloted as a low-carbon alternative to traditional diesel backup generators. This onsite energy strategy, which also includes Battery Energy Storage Systems (BESS), aligns with Digital Realty's goal of achieving 100% renewable energy use in its European operations. The $2 billion commitment represents one of the largest data center investments in the UK this decade, anchoring the London/Slough region as a premier hub for "AI Factories" in the pan-European market.
