ELK GROVE VILLAGE, Ill., May 20, 2008 (PRIME NEWSWIRE) -- Lime Energy (NasdaqCM:LIME - News) announced today that they have completed the Energy Analysis Project (EAP) study for a Fortune 500 Food Service company to analyze their consumption patterns and identify areas where they can further reduce energy consumption in their retail stores. Lime Energy has completed a statistical analysis of the electrical consumption at several thousand store locations, normalized the data, and selected 19 stores for a six-month monitoring phase. Every piece of equipment that consumes electricity in these select stores was monitored every 15 minutes for a six month period, and the data analyzed for potential energy savings. Feasible energy efficiency and conservation measures were then detailed and quantified in the second phase for implementation which meets the customer's financial and environmental sustainability goals.

``This project shows the depth and breadth of Lime Energy's capabilities,'' stated David Asplund, Chief Executive Officer of Lime Energy. ``Lime Energy was selected to provide this company with data, analysis and recommendations on exactly how to reduce their energy use so as to reduce their environmental footprint. We are honored they selected our firm to provide this engineering study and look forward to helping them implement the recommendations,'' concluded Mr. Asplund.
