In December of 1990 LES was selected by the county of Fairfax to develop the I-95 Landfill in Lorton, Virginia. The development plan included the installation of two separate generating facilities producing a combined gross output of 6.4 megawatts. The first phase of the power plant construction was completed in November of 1991. Phase I houses four Caterpillar 3516 engines and has been exporting in excess of 3MW to Dominion Power, formerly Virginia Electric and Power Company since it’s commissioning date. The plant consumes approximately 1150 standard cubic feet per minute of landfill gas and is located on the County’s 300 acre landfill. LES was responsible for all design, engineering, construction and commissioning services. In addition, the plant is owned, operated and maintained by LES. The success of this facility was highlighted in a 1992 Environmental Protection Agency case study on landfill gas-to-energy facilities.
