CSE teamed up with industry partners to test the ability of distributed energy resources to cost-effectively accomplish their main purpose of meeting on-site electricity needs while providing services to the grid.
Distributed energy resources (DERs), such as solar, wind and energy storage, present opportunities to optimize and balance California's electricity grid through demand response participation in wholesale energy markets.
The Center for Sustainable Energy (CSE) with subcontracted support from Olivine Inc., Tesla, Inc. (formerly Solar City, Inc.) Conectric Networks, LLC., and DNV-GL, led a multi-year technology demonstration pilot titled, “Meeting Customer and Supply-side Market Needs with Electrical and Thermal Storage, Solar, Energy Efficiency and Integrated Load Management Systems.” (EPC-15-074)
The project demonstrated how two behind-the-meter energy storage and DER technology portfolios could decrease customer utility bills through a combination of “active” and passive efficiency measures and onsite solar photovoltaic generation-to-storage while also earning revenue by direct participation in the California wholesale energy and ancillary services markets — as proxy demand resources.
Beyond providing day-ahead and real-time energy into the wholesale market, the project was among the first demonstrations of a resource behind-the-meter providing ancillary services via spinning reserves.
