National Grid — National Grid Ventures (NGV), the commercial arm of National Grid, has agreed to invest $1.75 billion for a 35% stake in Joulent LLC, a technology-driven energy company focused on developing power solutions for large electricity users, particularly AI data centers. The investment will support Joulent's first project, Project Kilby, a 2.67 GW co-located power facility in West United States — Texas developed in a 50/50 partnership with Chevron Corporation. The facility will supply electricity to a Microsoft-operated data center under a 20-year power purchase agreement, with first power delivery targeted for 2028. The partnership leverages NGV's expertise in high-voltage networks and infrastructure development, and is separate from National Grid's existing £70 billion capital investment program.
