of windmill in fieldThis page provides information on submitting a Small Generator Interconnection Request. A Small Generator can be a generator or an aggregation of generators, whose single or combined generating capacity is greater than 0.2 MW and equal to or less than 20 MW.

The interconnection of Small Generating Facilities to the Federal Columbia River Transmission System (FCRTS) is governed by Attachment N to BPA's Open Access Transmission Tariff (OATT). The Small Generator Interconnection Procedures (SGIP) provides the procedural framework for moving from a submitted Interconnection Request to a completed interconnection for generators of 20 MW or less (nameplate). BPA's Small Generator Interconnection Business Practice provides greater practical detail and should be consulted for specific questions. For any other questions, please contact the appropriate Transmission Account Executive, or the SGIP Administrator. Should a Small Generator wish to interconnect under Network Resource Interconnection Service, any such request will be studied under the Large Generator Interconnection Procedures.
