White Paper — NEM Energy Storage

California DC-Coupled Solar-Plus-Storage Net Metering Ruling:  A Technology and Policy Review

By Josh Weiner, CEO of SepiSolar

On January 31, 2019, the California Public Utility Commission (CPUC) issued a final decision granting a petition to modify Decision 14-05-033, which governs net metering in California. The modification allows certain DC-coupled energy storage systems that adopt UL-verified firmware to benefit from net energy metering (NEM). This white paper describes the history of this decision and its potential financial benefits to builders of solar-coupled storage systems, including:

  • For the first time in California, solar-plus-storage asset owners can export battery power onto the grid and receive NEM credits on all solar and storage exports, including those with aggregate (NEM-A) and virtual (NEM-V) tariffs.
  • Developers will be able to increase the size of their projects in California beyond 1 MW.
  • Developers and tax equity investors will be able to invest in solar-plus-storage projects and receive a potentially higher return on investment.
  • Much more…
