IEUA Completes 3.5-MW of Solar Projects

Inland Empire Utilities Agency (IEUA), a municipal water agency, and SunPower Corporation have completed 3.5-megawatts (MW) of solar power installations at four IEUA facilities in Chino, Ontario and Rancho Cucamonga, California. As a result of the installation, the agency expects to save a close to US $500,000 per year in electricity costs.

“With the completion of this new system, IEUA is now producing nearly half of its electricity from alternative energy sources,” said Patrick Shields, executive manager of operations at the IEUA. “SunPower provided high-efficiency technology to ensure we are maximizing the energy produced on site, and completed the installation in just five months. The solar system furthers our commitment to sustainable practices, and is a source of pride in the community.”

IEUA financed the project through Morgan Stanley under the SunPower Access power purchase agreement (PPA) program. Under the PPA, the agency is purchasing electricity generated from the system from the financier, which owns and operates the system. IEUA owns the renewable energy credits associated with the system.

The highlight of the system is a 1-MW SunPower T20 Tracker system located just behind the agency’s Chino headquarters. At the agency’s Regional Plant 1 in Ontario, a 700-kilowatt (kW) array of SunPower Trackers was installed alongside a 137-kW SunPower T10 Solar Tile system on top of a capped reservoir.

T10 Solar Tiles were also installed at two more locations. The first is a 624-kW array at the IEUA’s Carbon Canyon Treatment Plant in Chino. THe second is a 1-MW system atop the Inland Empire Regional Composting Authority (IERCA) located in Rancho Cucamonga.
