PowerSecure’s EfficientLights Refrigerated Case Lighting Revenues Expected to Reach $20 Million for 2009

Major Retailers Installed Over 100,000 EfficientLights Fixtures to Reduce Energy Costs and Improve Lighting Quality Since January

Wake Forest, N.C. — October 14, 2009 — PowerSecure International, Inc. (Nasdaq: POWR) today announced its EfficientLights refrigerated case lighting is being installed at a rapid pace by major retailers, and because of this strong demand the Company now expects revenues for the product to reach $20 million for 2009. This represents growth of approximately 650% over 2008.

So far this year, over 100,000 EfficientLights fixtures have been installed in refrigerated cases of grocery, drug, and convenience store chains to: 1) improve the quality of light illuminating the products in their cases, 2) reduce lighting energy costs by approximately 70%, 3) reduce maintenance expense by extending light life five-fold over traditional lighting, 4) lower stores’ carbon footprint, and 5) eliminate mercury-containing fluorescent lights.

Sidney Hinton, PowerSecure’s CEO, said, “We are thrilled with the strong demand we are experiencing for our EfficientLights technology, and the terrific product our EfficientLights team, led by Bryan Beatenbough, is delivering our customers. The uptake we are seeing is a result of the superior quality of light EfficientLights projects onto our customers’ products in refrigerated cases. The combination of benefits provided by our lights produces a substantial financial and environmental payback for our customers.”

Bryan Beatenbough, President of EfficientLights, commented, “Our lights are built to deliver consistent, high quality light over the long-haul. An important element of our success, recognized by leading retailers adopting our technology, is that our EfficientLights lighting utilizes ‘high powered’ LED technology to deliver more efficient light output. This is in sharp contrast to substandard lighting which misuses ‘low powered’ LEDs — which are not designed for the demands of continuous, customer-facing lighting applications. We engineer our EfficientLights product to provide ten years of consistent, dependable quality light — and the unmatched combination of quality and efficiency we build into every fixture is why we are the leader in the marketplace.”
