Legal Document- Regulation: Cal. Pub. Util. Code, Rule 21 Generating Facility Interconnections

Abstract

California's "Rule 21" generally applies to systems connecting to an investor-owned utility’s distribution grid, non-export generating facilities connecting to an investor-owned utility’s transmission grid and all net metered facilities in an investor-owned utility’s service territory. Systems connecting to an investor-owned utility’s distribution grid for the purpose of participating in a wholesale transaction must apply under the investor-owned utility’s Wholesale Distribution Access Tariff. Systems connecting to the transmission grid must apply to the California Independent System Operator for interconnection. Systems connecting to the grid of a municipal or cooperative utility must follow the interconnection procedures adopted by that utility.


Rule 21 clearly defines a series of screens meant to filter applicants into the study path most suited for their project. It also establishes fixed timelines for the screens intended to speed the process of approval. Also defined in the tariff are a variety of fees and deposits required at various stages of the interconnection process. Net metered facilities are exempt from most of these fees. The California Public Utilities Commission (CPUC) approved a proposed settlement in September 2012, enacting the first fundamental redesign of Rule 21 since 2000. The complete revised Rule 21 Tariff, as described at a high level below, can be found beginning on page 136 of CPUC Decision 12-09-018.
