Net Energy Metering
Multifamily Affordable Housing Solar Roofs Program 



In 2015, the California Legislature passed Assembly Bill 693 (AB 693) which requires the CPUC to allocate part of the funds that investor owned utilities set aside from their greenhouse gas allowance revenues for clean energy and energy efficiency projects for the Multifamily Affordable Housing Solar Roofs (MAHSR) Program. The bill authorizes for the Program an annual allocation of $100 million or 10% of available funds, whichever is less.    

In January 2016, the CPUC issued a Final Decision in Phase 1of the Energy Metering  (NEM) proceeding, creating a second phase which will address mandates in AB 693. AB 693 allows program achievements to count toward satisfying the CPUC’s mandate in the NEM proceeding to provide alternatives designed for growth of renewable distributed generation among residential customers in disadvantaged communities.     

On March 4, 2016, the CPUC issued a Ruling setting the Scope and Schedule for Phase 2 of the proceeding.


MAHSR Program Framework

On July 8, 2016, the CPUC issued a Ruling seeking comments and proposals from stakeholders on establishing the MAHSR program framework, including on issues of: 

  • Incentive structure
  • Program administration
  • How to allocate solar benefits “primarily” to low-income tenants
  • Whether storage devices can be included in the definition of a “solar energy system”


The CPUC anticipates a Proposed Decision on the Multifamily Affordable Housing Solar Roofs program framework in the fourth quarter of 2016.


Public Advocates Office Position

The Public Advocates Office (the Office) supports the goals of AB 693 to make solar energy systems more accessible to low-income and disadvantaged communities with the express purpose of lowering low-income tenants’ energy bills. 


 The Office finds that the best way to achieve the state’s goals is for the program to: 

  • Offer upfront, capacity-based incentives that are informed by a market research study on future Photovoltaic (PV) system costs.
  • Use a third-party as statewide administrator.
  • Include optional incentives for a paired storage device.
