Disclosed scale$1.75B National Grid Ventures investment for a 35% stake in Joulent, forming a strategic partnership to develop contracted power and electrical infrastructure for U.S. large-load demand; proceeds are expected to enable Joulent's foundational Project Kilby, a 2.67 GW West Texas co-located power facility serving a Microsoft-operated data center under a 20-year PPA with Chevron

Why it matters

The strategic read

Turns Joulent from a project-specific AI power developer into a National Grid-backed platform. The scarce input is not only gas turbines or a single Microsoft PPA: it is financeable, utility-grade execution for large-load data-center power. National Grid is buying exposure to contracted critical infrastructure in the AI-driven large-load economy while adding high-voltage, grid-integration and project-execution capability around Joulent's Across-the-Meter model.
