Qualifying Facilities (QFs) are power producers or co-generators who can sell their electricity to public utilities. QFs generate about 25 percent of PG&E's energy supply. Energy deregulation has allowed these generators to choose the markets in which they sell the electricity they generate.
If you are a QF generator and your current Power Purchase Agreement (PPA) is expiring, or you intend to sell power into additional or different markets, you will need to execute a new PPA as well as replace your current interconnection agreement with PG&E. The type of PPA you choose and whether you connect at the Transmission level (60 kV and above) or Distribution level (less than 60 kV) will determine the type of interconnection agreement you sign with PG&E. This page explains the different types of interconnection agreements and the resources available to help you renew your agreement with PG&E.
PG&E's Generation Interconnection Services (GIS) offers outreach and education about interconnection and helps customers manage the interconnection process. There are no costs associated with PG&E's services related to this process. The renewal process can be a lengthy one, so we recommend you begin taking the required steps at least six months before your current PPA expires.
There are three types of agreements that detail the terms of a facility's interconnection with PG&E—a California Independent Systems Operator (CAISO) Tariff agreement, a Rule 21 agreement and a Wholesale Distribution Tariff (WDT) agreement:
The type of agreement you may enter into is determined by the type of PPA you sign:
