EnerNOC Signs 110 Megawatt Contract With Southern California Edison

EnerNOC, Inc. (NASDAQ: ENOC), a leading developer and provider of clean and intelligent energy solutions, today announced that it has entered into a new demand response agreement with Southern California Edison (SCE).

The agreement includes up to 110 megawatts of capacity over its term, which expires in 2012. The capacity under an initial 40 megawatt agreement, which expires at the end of this year, will be enrolled under the new agreement, resulting in a four-year extension and an additional 70 megawatts of contracted capacity between the parties. The new agreement is subject to final approval by the California Public Utilities Commission.

EnerNOC will continue to aggregate demand response capacity from commercial, institutional and industrial customers within SCE's approximately 50,000 square-mile service territory. During periods of peak demand, SCE will signal EnerNOC to provide demand response capacity. EnerNOC will do so by remotely initiating demand response measures at participating customers' sites and monitoring performance in near real-time from its Network Operations Center.

"We are excited to build upon the relationship that we have forged with EnerNOC. Demand response programs are an essential part of providing clean, cost-effective technology solutions to further enhance the reliability of the electric power grid," said Lisa Cagnolatti, SCE vice president, Business Customer Division.

"By effectively working together with SCE over the past year, we have laid the groundwork to continue to expand the role of demand response in Southern California," said Tim Healy, chairman and CEO of EnerNOC. "California's energy demand cannot be met by supply-side solutions alone, and we believe that technology-enabled demand response is an important and sustainable component of our energy future."
