Behind the meter, explained

Behind-the-meter generation produces electricity on the customer's side of the utility meter, so power flows directly from generator to load without ever touching the transmission grid. Front-of-meter generation does the opposite: it sells into the grid and reaches customers through wires, tariffs, and an interconnection queue. For a large load like an AI data center, which side of the meter the electrons come from decides the timeline, the cost stack, and who controls reliability.

The meter is a boundary, not a device

Everything on the grid side of the meter is shared infrastructure: transmission lines, substations, tariffs, and the study processes that ration access to all of it. Everything on the customer's side is private. A behind-the-meter plant and its load are one electrical system with one owner-operator relationship — designed, permitted, and energized together, on one schedule.

That is why the same megawatt behaves so differently on each side of the line. In front of the meter it must be studied, queued, and socialized across every other user of the shared system. Behind it, the only parties in the room are the generator and the load.

What it means commercially

No transmission service, because the power never crosses the grid. No retail tariff, because there is no utility sale — the commercial relationship is a direct contract between generator and load, priced on fuel and steel rather than on a regulated rate stack. And no interconnection queue, because there is no interconnection; the timeline is set by equipment, permitting, and construction. The ERCOT queue, explained covers what is being skipped, and the cost math covers what is being saved.

Common configurations

The simplest is on-site prime power: dedicated generation sized for the full load, with redundancy engineered in, running as the permanent and primary source of supply. Variants include bridge power, where behind-the-meter generation carries the load until a grid connection eventually arrives, and grid-parallel designs that keep a utility tie for supplemental or backup service. Fully islanded prime power — no grid tie at all — is the configuration that removes grid dependency entirely, and it is the basis of the power foundry model described in what is a power foundry?.

Is it legal?

Yes. Serving your own load with your own generation is well established, and Texas in particular has a long-recognized framework of private-use networks under which large industrial sites have self-supplied for decades. AI data centers are a new load, not a new legal question. The practical constraints are air permitting, fuel supply, and engineering — not permission to exist. What matters in diligence is whether a specific provider has actually cleared those constraints on a specific site, which is the subject of how to evaluate a BTM power provider.

About Corley Energy

Corley Energy is a behind-the-meter independent power producer, founded in 2024 by Jake Corley, Tim Bozeman, and Mark Meyer. We convert stranded Permian Basin natural gas into firm, contracted electricity for AI data centers at Power Foundry, our ~1,000-acre development in Upton County, Texas.
