The Las Virgenes-Triunfo Joint Powers Authority (JPA)—comprised of Las Virgenes Municipal Water District and Triunfo Sanitation District—provides wastewater treatment, recycled water and biosolids composting to residents of Agoura Hills, Calabasas, Hidden Hills, Oak Park, Westlake Village and a portion of Thousand Oaks plus surrounding unincorporated areas of Los Angeles and Ventura Counties. The JPA has a long tradition of promoting recycled water use and sought a way to expand its sustainability efforts to electricity.
As a member of the Association of California Water Agencies, the JPA learned that many fellow members turned to solar energy for clean, renewable power and reduced energy costs. After careful research and planning, the JPA partnered with SolarCity to install a 1 MW solar power system that covers six acres of land and generates more than 2 million kilowatt hours of solar electricity every year.
The SolarCity Power Purchased Agreement let JPA switch to solar power with no upfront cost. They only pay for the solar energy the system generates at a rate that’s lower than they currently pay the local utility company. This is expected to help them save more than $2 million* over the next 20 years. The savings are not only economical. Over the lifetime of the ground-mounted system, the solar energy produced is estimated to offset more than 82 million pounds of carbon dioxide emissions, equivalent to planting more than 44,785 trees.
