Ameresco completes solar set up on Foothill Landfill in San Joaquin County, Calif.


Ameresco has completed construction of a 5.3 MW DC solar system for ground mounting in San Joaquin County, California’s Foothill Landfill. This is Ameresco’s second renewable energy project with the county and will help lower utility bills through California’s self-generated renewable energy bill transfer program.

“San Joaquin County and its local communities have long made the development of renewable energy sources a priority to both reduce emissions and complement existing power generation,” said Kathy Miller, chairman of the board of directors of San Joaquin County. “In addition to its environmental impact, our region’s solar power system will bring further savings in utility costs, which will benefit residents and local governments directly to better serve their constituents.”

Project details. San Joaquin County has partnered with Ameresco to develop, own and operate a floor-mounted solar photovoltaic system at the Foothill Landfill in Linden, California. Financed by a power purchase agreement, Ameresco installed 13,770 solar modules with a direct current of 385 W each and 29 solar inverters with an alternating current of 125 kilowatts each. Under a separate agreement with San Joaquin County, Ameresco built a 4.3 megawatt landfill gas power plant on the same landfill in 2014.

The solar system will generate around 10,473,000 kilowatt hours of electricity in the first year. This corresponds to a reduction in CO2 emissions of 7,405 tonnes or the energy consumption of 854 households for one year. In addition to the significant electricity savings, the county will receive an upfront payment of $ 500,000 to use the property, adding revenue to the county from day one.

“We knew there was a similar opportunity to do something productive with the site thanks to a previous project done in partnership with Ameresco on the site,” said Chuck Winn, director of San Joaquin County. “When Ameresco approached us about the potential use of the undeveloped land for solar systems, it was an opportunity we couldn’t pass up. This is a long-term partnership and the resulting project will be of great benefit to the county and our residents. “

“Our continued collaboration with San Joaquin County shows that there are always additional opportunities to make a community more sustainable and energy-safe,” said Bob Georgeoff, vice president of Ameresco. “We look forward to this project delivering environmental benefits while delivering significant financial savings for San Joaquin County.”

Construction on the San Joaquin County solar project was recently completed. Ameresco continues to work with several parties involved in its development including Sage Energy Consulting, PG&E, the San Joaquin Council, the Linden Fire Department, the California Department of Fish and Wildlife, the California State Water Resources Control Board, and the California Environmental Quality Act and the San Joaquin Valley Air Pollution Control District.
