The point of common coupling (PCC) is the physical location in the electricity network where the boundary between a utility's infrastructure and a customer's installation is defined, and where power exchange between them is measured.
===== Why this matters =====
===== Shared definitions =====
The IEEE defines the point of common coupling as the point in the power system at which the interface between the electric utility and the customer occurs.((Jones, K., McCurry, W., & Zitelman, K. (2023). //State microgrid policy, programmatic, and regulatory framework: NASEO-NARUC Microgrids State Working Group//. National Association of State Energy Officials and National Association of Regulatory Utility Commissioners, August 2023. https://pubs.naruc.org/pub/2649E6EB-D7CE-77DC-2BE3-89D48A713213)) In general, this is the customer side of the utility's meter. The PCC is a key reference point in grid connection standards, microgrid design, and distributed energy resource regulation, as it determines the boundary of measurement, responsibility, and control between network operator and customer.
