Solar Facilities

In August, the Water Authority completed the installation of solar panels at three key facilities, which will help manage its energy costs and reduce the agency’s carbon footprint. The solar panels were installed at no cost to the Water Authority under a 20-year power purchase agreement with Borrego Solar Systems, Inc.

In all, more than 7,500 solar panels are now in operation at the Water Authority’s Kearny Mesa headquarters, Fred A. Heilbron Operations Center in Escondido, and at the Twin Oaks Valley Water Treatment Plant north of San Marcos. Borrego Solar estimates that the systems will generate enough renewable energy to meet approximately 60 percent of the needs for the Kearny Mesa facility, 55 percent for the Escondido facility, and 25 percent for the water treatment plant.

Based on anticipated future costs, the systems are projected to save the region’s ratepayers approximately $1.7 million in energy costs over the next 20 years.

Borrego Solar also estimates that these systems will produce enough renewable energy over the next 30 years to prevent more than 100 million pounds of carbon dioxide emissions. That’s the effect of planting more than 900 acres of trees or conserving nearly 145,000 barrels of oil.

The Water Authority secured two Blink® electric vehicle charging stations for its Kearny Mesa headquarters. These Blink charging stations are owned and operated by ECOtality, project manager of the EV Project. The EV Project is the largest deployment of electric vehicles and charge infrastructure in the United States. With additional funding from Borrego Solar, the Blink charging stations allow employees to charge their vehicles from solar power, at their own expense, creating no cost impact to the Water Authority.
