California's Biggest Energy Consumer: Water Treatment

When we think of California's high energy consumption, most of us assume that residential and commercial buildings are the largest contributors. Surprisingly, a major portion of the state’s energy demand—over 19%—is dedicated to water treatment and pumping alone. With nearly 37 million residents, California’s water and wastewater facilities account for over $500 million in energy expenses annually, costs that continue to rise due to climbing utility rates.

Castaic Lake Water Agency's Solar Solution

To address both energy costs and environmental concerns, the Castaic Lake Water Agency (CLWA) in Santa Clarita has taken a significant step toward sustainability. Partnering with SunPower, a leading solar provider, CLWA plans to install a 1-megawatt solar energy system capable of offsetting more than 98% of the agency's annual energy consumption. SunPower’s experience with California water facilities is extensive, with over 20 megawatts of solar systems already installed across the state.

The new facility will use SunPower’s advanced T0 tracking technology, which adjusts solar panel angles to follow the sun's path throughout the day. This design maximizes energy production and efficiency, enabling CLWA to generate more power using fewer panels. By switching to solar, the agency is poised to reduce its carbon footprint significantly while safeguarding against fluctuating electricity costs.

A Strategic 20-Year Power Purchase Agreement

CLWA’s solar project is made possible by a 20-year Power Purchase Agreement (PPA) with SunPower. In this arrangement, PNC Energy Capital owns the solar system, and CLWA purchases the generated electricity at predictable rates. This structure not only secures CLWA against unpredictable rate hikes but also allows PNC Energy Capital to capitalize on tax incentives, making solar power more accessible for public utilities.

SunPower, known for its highly efficient solar panels and industry-leading 25-year warranty, will also manage the system’s operations and maintenance, ensuring a reliable energy supply for the next two decades.

Green Convergence: Bringing Solar to Santa Clarita

As the only Elite SunPower dealer in the Santa Clarita Valley, Green Convergence is proud to support this initiative, part of a larger movement toward solar energy in Santa Clarita and beyond. This project aligns with the William S. Hart School District’s recent commitment to solar, where over 7 megawatts of photovoltaic energy will soon power nine different locations across the district.

California leads the U.S. in solar adoption, with over 2,150 megawatts installed statewide by 2010 alone. Over the last few years, the demand for solar has surged, creating thousands of jobs, cutting costs for consumers, and reducing greenhouse gas emissions.

A Future Powered by Clean Energy

Santa Clarita’s commitment to solar energy marks a significant milestone in the community's journey toward sustainability. Every solar installation, whether at a water treatment facility, a school, or a home, helps create jobs, promotes energy independence, and contributes to a cleaner, greener future.
