Implementation of AB 693 - Solar on Multifamily Affordable Housing (SOMAH)

Multifamily Affordable Housing Solar Roofs Program (AB 693)

Assembly Bill (AB) 693 (Eggman, Chapter 582, 2015) provides financial incentives for the installation of solar energy photovoltaic (PV) systems on multifamily affordable housing properties throughout California.  The statute, among other things, prescribes criteria for participation in the incentive program; sets targets for installation of solar PV systems; identifies various required elements for the Program; and gives direction to the California Public Utilities Commission on the administration of the Program.

Key components of the legislation, and the forthcoming program, include:

  • Directing $100 Million, annually, from the electric IOU's Greenhouse Gas Auction Proceeds towards subsidized solar energy systems on Multifamily affordable housing.
  • Encourages development and installation of solar systems in California's disadvantaged communities across the state
  • Emphasizing the explicit goal that incented solar systems lower the energy bills of tenants of low-income multifamily housing
  • Develop, by December 31, 2030, at least 300 megawatts of installed solar generating capacity

In response to the legislation, the Commission, in proceeding R.14-07-002, issued a Ruling to stakeholders seeking input on the design, implementation, eligibility and other programmatic issues for the new program.  Nearly 25 parties provided over a thousand pages of comments in response to the ruling.

The Commission has recently issued D.17-12-022 which outlines the program design for the Solar on Multifamily Affordable Housing (SOMAH). The Decision builds on many of the program successes and lessons learned from the Multifamily Affordable Solar Housing (MASH) Program. For additional information on the SOMAH Program and Decision, please consult this press release.

Following the issuance of D.17-12-022, the Commission's Energy Division selected via a competitive bidding process, a single, statewide program administrator team.  The SOMAH Nonprofit Administrative Partnership (SNAP) team is comprised entirely of non-profit organizations: the Center for Sustainable Energy (CSE), GRID Alternatives, the Association for Energy Affordability (AEA), the California Housing Partnership Corporation (CHPC) and Rising Sun.
