Definition
The sequential production of electrical energy and useful thermal energy (steam, hot water, or process heat) from the same fuel source in a single facility. Cogeneration — also called combined heat and power (CHP) — achieves higher overall fuel efficiency than separate electric generation and on-site boilers, and is a common Qualifying Facility (QF) type under PURPA. Cogeneration plants often interconnect at industrial sites near load centers, which can reduce transmission flow requirements but may also create localized power flow and voltage impacts that must be evaluated in interconnection studies.
