Point of common coupling
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.
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.”1) 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.
