NOTE: The MASH program waitlist will be closed to new applications at 5 PM on April 10th. Please see the section below titled Program Waitlist for more information.
The California Solar Initiative's Multifamily Affordable Solar Housing (MASH) Program has issued the January 2014 edition of the MASH Semi-Annual Progress Report, which provides detailed information on the MASH Program's progress in each of the three service territories in California. Recent highlights and milestones of the program include:
- 17.99 MW of solar capacity is now interconnected across 293 projects statewide that serve multi-family affordable housing.
- 93 MASH Track 1 projects are currently reserved, with capacity of more than 10.1 MW.
- More than $68 million has been paid to completed projects; an additional $25 million is reserved for pending projects.
- After being expanded by previous CPUC decisions, there are now over 8,600 tenant units participating in Virtual Net Metering thanks to the MASH program.
AB 217 Implementation
Assembly Bill 217 (Bradford, 2013) extended the MASH and SASH programs of the California Solar Initiative with $108 million in new funding, and set several new goals for the programs. To read the Energy Division’s July 2014 staff proposal regarding the implementation of AB 217 at the Commission, please visit this link. For this and all other documents released in the Commission’s R.12-11-005 rulemaking, please visit the R.12-11-005 Docket Card page.
The Energy Division has hired Navigant Consulting, Inc. to perform in-depth evaluations of CSI SASH and MASH program design, delivery, operations, and impact in 2014 and 2015. This new round of program evaluation will build upon the previous SASH and MASH studies completed in 2011, available through the links below. Energy Division staff anticipate the release of three reports by mid-2015: a program administrator and market assessment, a benefit-cost analysis, and a summary of program design recommendations encompassing both programs.
On August 4, 2011, Navigant Consulting, Inc issued the CSI SASH and MASH Impact and Cost Benefit Report.
On June 10, 2011, Navigant Consulting, Inc issued the CSI MASH Biennial Report
On April 5, 2011, Navigant Consulting, Inc issued the CSI SASH and MASH Program Administrator Performance Assessment Report, which provides an evaluation of the MASH Program."
On April 1, 2011, Navigant Consulting, Inc issued the SASH program. The CSI SASH and MASH Market Assessment Report, which provides an evaluation of the MASH program.
The Multifamily Affordable Housing (MASH) program across all three Program Administrator (PA) territories – Southern California Edison (SCE), Pacific Gas & Electric (PG&E) and California Center for Sustainable Energy (CCSE) will close its waitlist April 10, 2014 at 5pm PDT. At this time, there are plenty of waitlisted applications to backfill existing projects that may yet withdraw or cancel. As a result, the MASH Program Administrators along with the Energy Division have decided to close the waitlist statewide to new applications.
The program administrators expect that there will be questions related to the treatment of waitlist applications once Assembly Bill (AB) 217 is implemented in the MASH program. Unfortunately, this question cannot be answered at this time, as it is a matter that will need to be addressed publicly and transparently through the AB 217 implementation process in the CPUC’s R.12-11-005 regulatory proceeding. The MASH PAs will resume accepting applications once AB 217 has been fully implemented and the CPUC gives the approval to do so. Should you have any questions, please feel free to contact your local Program Administrator, whose contact information is below.
About the MASH Program
Established in 2008, the MASH Program provides solar incentives on qualifying affordable housing multifamily dwellings. The goals of the MASH program are to:
Stimulate the adoption of solar power in the affordable housing sector;
Improve energy utilization and overall quality of affordable housing through the application of solar and enrgy efficiency technologies;
Decrease electricity use and costs without increasing monthly household expenses for affordable housing building occupants; and
Increase awareness and appreciation of the benefits of solar among affordable housing occupants and developers.
The MASH program provides two types of incentives - Track 1 incentives and Track 2 incentives. Track 1 incentives provide fixed, upfront capacity-based incentives for solar PV systems that offset common area and tenant loads. The MASH Track 1 incentive reate structure is as follows:
MASH Track 1 Incentive Rates (shown in $ per watt)
PV System Offsetting
Common Area Load
PV System Offsetting
Track 2 offers higher incentives to applicants who provide quantifiable “direct tenant benefits” (i.e. any operating costs savings from solar that are shared with their tenants). Track 2 incentives will be accepted every six months through a competitive process. The MASH Program Administrators are currently developing a statewide application and review process for Track 2 incentives.
To qualify for MASH Track 1 or Track 2 incentives, a property must meet the definition of “low-income residential housing” per Public Utilities Code 2852 and have occupancy permit for at least two years prior to applying for incentives.
