In 1998, our Utility Built Solar (UBS) program began installing solar on City-owned rooftops and parking lots to prepare Los Angeles for the growing impacts of climate change. With over 47 projects, there have been 25 megawatts (MW) of solar installed making LADWP’s energy greener. This is equivalent to the pollution reduction of powering 7,622 homes or taking 3,086 cars off the road annually.
