PJM Grid · Self-supply

A generator label is not a reliability credit.

Behind-the-meter, grid-connected, queued, and flexible-service arrangements create different system obligations.

“Self-generation” is not one grid outcome.

The reliability credit depends on electrical and contractual structure, not the technology label. This repaired study removes the behavioral death-spiral forecast and asks the bounded question: does the capability reduce the grid obligation when the system is short?

Firm additions receive 90% availability—not a nameplate pass.

The policy builder treats “new firm” as a modeled capability with a declared availability factor. It does not assert that gas, nuclear, storage, or any other technology automatically earns that value. PJM accreditation and performance rules decide the real UCAP contribution.
