Calif. PUC Directs Retail Suppliers To File Plans To Achieve Carbon Reduction Targets
March 27,2020
The California PUC adopted an "optimal portfolio," known as the Reference System
Portfolio (RSP), to be used by all load-serving entities (LSEs), including retail suppliers, required to file
individual integrated resource plans (IRPs) in 2020
In their plans, all LSEs must demonstrate how they would meet their share of an adopted 2030 GHG target for the electric sector of 46 million metric tons (MMT), as well as a deeper target of 38 MMT by 2030.
"The optimal portfolios, like the previously adopted 2017-2018 RSP in D.18-02-018, include a large amount of new solar, wind, and battery storage resources, as well as long-duration storage and out-of-state wind on new transmission. The Commission will explore further in the procurement track of this or a successor proceeding how to go about ensuring that these additional resources, or others with equivalent attributes, are planned for and procured for the benefit of the sector as a whole," the PUC said
"In their individual IRPs, LSEs are required to show how their procurement to date, and planned procurement in the future, of electricity resources will help the state collectively meet this optimal portfolio and GHG target," the PUC said
