Behind the Meter Microgrid Power Purchase Agreements & xAI

Deploying 100,000 liquid-cooled GPU clusters requires unprecedented quantities of dedicated firm electrical capacity. Contract modeling in the xAI Colossus power capex calculator outlines how developers use behind-the-meter (BTM) microgrid Power Purchase Agreements (PPAs) to bypass transmission interconnection queues.

In a behind-the-meter topology, generation assets are physically wired on the customer side of the utility meter, eliminating the need to wait for regional transmission operator (RTO) cluster studies. Energy developers finance, install, and operate on-site generation, selling electricity directly to the compute cluster under long-term structured contracts.

Key contractual clauses include availability guarantees, heat-rate pass-through mechanisms, and liquid fuel capacity reservation fees, ensuring the AI campus obtains uninterruptible power while hedging against wholesale merchant electricity price spikes.
