Energy Systems Group (ESG) Recognized for Commitment to Renewable Energy

WASHINGTON, DC--(Marketwire - January 16, 2008) - The U.S. Environmental Protection Agency (EPA) presented Energy Systems Group (ESG) with a 2007 Project of the Year Award for its Iris Glen Landfill Gas to Energy Project. The award was presented at EPA's 11th Annual Landfill Methane Outreach Program (LMOP) Conference and Project Expo on January 9, 2008 in Washington, DC.

Natural gas quality landfill gas (LFG) energy projects are typically limited to landfills with significant amounts of gas, but not in Johnson City, Tennessee. There, Energy Systems Group has successfully transformed a relatively low landfill gas (LFG) flow into an award-winning pipeline quality LFG energy project. The Iris Glen Landfill Gas to Energy Project's innovation, extensive outreach, and success earned it recognition as a 2007 LMOP Project of the Year.

An innovative collaboration between the City of Johnson City, TN and Energy Systems Group, the landfill project employs inventive use of landfill gas that conserves natural resources, reduces greenhouse gases, and provides a long-term revenue source for the City of Johnson City.

ESG engineered and built the landfill gas processing system to convert raw low BTU gas to clean high BTU gas as a direct replacement for natural gas that is then supplied to the Mountain Home Energy Center (MHEC). The MHEC is a combined heat and power plant that supplies power and chilled water to a Veterans Administration hospital, the East Tennessee State University Medical School, and the city's civic center.

The Iris Glen Landfill Gas to Energy Facility eliminates the equivalent amount of emissions as would be saved by removing 34,000 cars from the road, or planting 49,000 acres of trees, or heating over 11,000 homes.

"We are extremely proud of this investment and pleased to deliver all the benefits of such an environmentally responsible project," commented Jim Adams, President of Energy Systems Group. "ESG continually develops innovative projects that promote energy conservation while providing significant financial benefits to the communities we serve."

Each year, EPA recognizes the latest accomplishments of landfill methane partners who have reduced emissions of methane and created renewable energy. The Landfill Methane Outreach Program (LMOP) acknowledges its Partners for excellence in innovation and creativity, success in promoting project development, and achieving environmental and economic benefits.
