Project Profile

 
West County Waste Solar Project

Overview

SPP developed a 1.014 MW total dual-axis tracking solar energy system for the West County Wastewater District in Richmond, California. The system, which was developed using a solar Power Purchase Agreement, is the largest system of its size in the US.

Results

SPP's in-house construction management drew upon over thirty years of experience with a variety of construction methods to solve the technical obstacles. With EPC partner Premier Power, the solar structures were designed to be dimensionally stable without causing differential settlement. Geotechnical engineering firm Questa Engineering contributed a controlled-density fill (CDF) sub-foundation to control the spread of weight.

The iconic system is a visually stunning example of partnership between public and private entities. The system was built in just four months after engineering challenges were solved, and the result is an industry award-winning system that generates fixed-price solar power for twenty or more years.


Project News

The US EPA has profiled the West County Wastewater District on its website. The system is one of five projects highlighted under the EPA's Renewable Energy Electricity Generation Facilities and the only one completed with a private solar power developer in the category.

"I was pleased how quickly the units were assembled; having something assembled of this magnitude under a tight time constraint is pretty impressive. We were pleased with the product and design Solar Power Partners and Premier Power put forward on our site. Without the solar Power Purchase Agreement our cost to deploy would have been more challenging. Our ratepayers win, as we now have contractual stability over much of our energy costs for years to come. The working relationship between our staff, Solar Power Partners and Premier Power was extremely well tuned."
