California Tariff Proposal Opens Wholesale Market to Small Distributed Energy Resources

New policy proposals at both regional and state levels could increase access to wholesale markets for aggregated distributed energy resources (DERs). The California Independent System Operator (CAISO) filed tariff revisions with the Federal Energy Regulatory Commission (FERC) on March 4, 2016, to enable aggregated DER to participate in the ISO’s wholesale markets. DER initiatives in New York, Hawaii, and Texas could also identify optimal solutions to balance renewable energy growth with grid safety and reliability. Access to these markets will be a critical advancement for rooftop solar and solar storage, particularly as DER adoption continues to expand with enhanced technology capabilities, environmental regulations, and fossil-fuel retirements.
