PowerSecure Awarded Contract to Build Transmission Lines to

Support a Series of New Oil and Gas Production Sites

Wake Forest, N.C. – March 5, 2012 – PowerSecure International, Inc. (Nasdaq: POWR) today announced it has been awarded a new contract to build electrical transmission infrastructure to support a series of new oil and gas production sites. The boom in oil and gas drilling and production activity, driven by new low-cost technologies, is driving an immediate need for new electrical infrastructure in remote areas to support these operations.

PowerSecure’s work under this new contract will be performed on behalf of a major energy company, in partnership with a prominent electric utility. The award is for several million dollars of electrical transmission design and construction, the majority of which is expected to be completed by mid-2012. The Company will include the revenue associated with this new award in its revenue backlog published in conjunction with its fourth quarter 2011 earnings release on March 8, 2012.

Sidney Hinton, CEO of PowerSecure, said, “We are excited to announce this new award supporting a major energy company and electric utility to accelerate oil and gas production activities. The opportunities to serve this booming market are significant, and our capabilities line up perfectly to serve energy companies and utilities with their infrastructure requirements. In fact, addition to our utility infrastructure services, we see a growing opportunity to serve this market with our distributed generation systems. We are very excited about this new assignment, and future opportunities to grow our service to the oil and gas industry.”
