Generation Integration

Generators that are not directly connected to BPA's Transmission System but connect to a host utility within BPA's Balancing Authority Area are considered integrations. Generator integrations are subject to the Generation Integration Services Business Practice, which provides the procedures and requirements for generators interconnecting and operating in BPA’s Balancing Authority Area.
