boundary of ownership
boundary between the assets of the grid company and the customer's electrical equipment of distributed resources
3.2
metering point
point at which electricity is exchanged between a distributed resource and the distribution network
3.3
point of interconnection
For resources connected to the public grid through a transformer, it refers to transformer's bus at high-voltage side that is directly connected to the public grid. For resources not directly connected to the public power grid through transformers, it refers to the bus of resources output, also called access point.
