National Grid backs Joulent’s dedicated power plant for Microsoft AI

National Grid backs Joulent’s dedicated power plant for Microsoft AI is a business and technology story about dedicated power plants for AI data centers.

What changed

The core facts are: National Grid Ventures will invest $1.75 billion for a 35% stake in Joulent, valuing it around $5 billion; the money supports Project Kilby, a 2.67 GW gas-fired plant in West Texas owned with Chevron; the full baseload output is tied to Microsoft under a 20-year power purchase agreement; the design sends power directly to server racks, bypassing public grid interconnection queues.

Why it matters

The signal is that AI power demand, grid queues and private gas-fired capacity. The story is less about a single announcement than about how AI is moving into budgets, infrastructure, regulation and operating workflows.

What to watch

The next check is whether direct gas generation becomes a common workaround for AI load growth and how the carbon cost is handled.
