EnerNOC Appoints Duke Energy Executive, James L. Turner, to Board of Directors

EnerNOC, Inc. (NASDAQ: ENOC), a leading developer and provider of clean and intelligent energy solutions, today announced that it has appointed James L. Turner to its Board of Directors. Mr. Turner is president and chief operating officer of U.S. Franchised Electric and Gas for Duke Energy Corporation and currently serves on the Board of Directors of the Electric Power Research Institute.

"Jim's broad industry knowledge and experience will be an excellent complement to our Board as it helps shape and guide our future growth," said Tim Healy, chairman and CEO of EnerNOC. "His leadership at Duke Energy, a utility that has demonstrated a strong commitment to energy efficiency as the 'fifth fuel' and to the modernization of the electric power grid, gives him unique insight into the challenges that utility executives face today and how technological innovations, like those provided by EnerNOC, can help address those challenges."

Duke Energy is one of the largest power companies in the United States, supplying and delivering electricity to approximately four million customers in the Carolinas and the Midwest.

EnerNOC has established a leadership position in energy management, and I look forward to lending my experience as we build a cleaner, smarter electric power industry," said Turner.
