LADWP - Solar Incentive Program

June 04, 2019


The Los Angeles Department of Water and Power's (LADWP) Solar Incentive Program began in 2000, with a funding level of $150 million. The California Solar Initiative, created in 2007 upon the enactment of SB 1, established new guidelines for municipal utilities to follow, and established new funding levels. The LADWP Board of Commissioners approved the Solar Incentive Program Guideline Revisions on September 4, 2007, to comply with SB1. The revised program was suspended in early 2011, but was revised and relaunched on September 1, 2011.

The Solar Incentive Program has 10 phases with declining incentive levels as certain installed megawatt (MW) targets are met. There are separate goals for residential and non-residential participants, and the incentive levels for each will decline irrespective of the other. All incentives are adjusted for expected performance. Systems may be eligible for bonus incentives if they utilize equipment manufactured in LA or if the systems is building-integrated PV.

LADWP’s 10-year, $313 million Revised Solar Photovoltaic Rebate Program began in 2007 and will remain in effect through December 31, 2017, or until the total installed MW goal has been reached.
