On November 4, 2010, Frederick County, Virginia initiated operations for a unique landfill gas (LFG) energy project, developed by the County's Department of Public Works. Following initial concern within the community about the development of new power transmission lines, the County successfully designed the project to support the local power grid without the need to build additional lines. The County worked with SCS Engineers and SCS Field Services, who designed and constructed the facility. County officials made the extra effort to inform the community about the project and its environmental and financial benefits.

Because there were no suitable end users to directly use the LFG, this project instead utilizes two engines to generate electricity on site, which is then managed and distributed by PPL Energy Plus. The engines generate approximately 2 MW of electricity, enough to power 1,200 homes in Frederick County.

By developing the project themselves and retaining the gas rights, the County is responsible for maintenance and compliance issues but decided that maintaining the gas rights would be a successful strategy for securing the long-term generation of revenue. The payback period on the capital investment is estimated to be between 5 and 9 years.

It is a beneficial project on various aspects, mitigating greenhouse gases and also offsetting fossil fuels that would otherwise be burned. —Darrin Dillah, Vice President, SCS Engineers
