Local officials were on hand March 29 for the dedication of the 22-MW landfill gas Bowerman Power Project in Orange County, California.
The landfill gas-to-electricity plant at the Frank R. Bowerman landfill east of Irvine will power thousands of local homes and businesses in Anaheim, generate millions of dollars in royalties for the county government system, and provide other environmental and economic benefits, project backers said in a news release.
The $60m 113,000-sq.-ft., state-of-the-art facility occupies 2.6 acres of the 725-acre Bowerman Landfill, one of the largest on the West Coast. Financed by Caterpillar Financial Services (Cat Financial), the project was developed and is owned and operated by Bowerman Power, a subsidiary of Pennsylvania-based Montauk Energy.
The project should provide generation of an estimated 160,000 megawatt-hours (MWh) of electricity, sufficient to serve the equivalent of 26,000 homes, sold to Anaheim Public Utilities to power residences, schools and businesses
It generates electric power by capturing landfill gas created by the millions of tons of waste buried at Bowerman. A natural byproduct of solid waste decomposition, the gas contains high amounts of methane, a prevalent greenhouse gas. The operation also will prevent approximately 53,000 tons of CO2 emissions annually.
Seven Caterpillar reciprocating engine-generators with gas clean-up and emissions reduction technologies that meet all local-state-federal air quality requirements are deployed at the site.
The green project won approval from the Orange County Board of Supervisors in October 2014 after a previous agreement for the facility was revised and updated. Ground was broken in January 2015.
The Bowerman Power Project is Orange County’s third landfill gas-to-energy facility. The other two are Olinda (Brea) and Prima Deshecha (San Juan Capistrano). Together, the three facilities produce approximately 380,000 megawatt-hours of electricity annually, enough to power some 56,000 homes in Southern California.
