EnerNOC, Inc. (ENOC), a leading developer and provider of clean and intelligent energy solutions, today announced that it has entered into a five-year contract with the State of Rhode Island. The contract will allow EnerNOC to enable and manage demand response capacity from city, town and government-related buildings into the Independent System Operator of New England, Inc. (“ISO-NE”) market, creating a valuable revenue stream for the State both today and in the future as part of ISO-NE’s Forward Capacity Market.

"As Rhode Island is facing skyrocketing energy costs and consumers are being asked to pay more for electricity, reducing non-essential consumption is an important component of our commitment to support reliable, cost-effective and environmentally sustainable energy solutions," said Governor Donald L. Carcieiri.

Under contract terms, individual government buildings can enroll in EnerNOC’s technology-enabled demand response network. Each site will be paid for agreeing to reduce non-essential electricity consumption during periods of peak demand. In addition, each participating site will gain basic access to EnerNOC’s PowerTrak energy management platform, which enables users to view and analyze their energy consumption data in near real time and measure efficiency gains.

“This is a positive development in Rhode Island’s broader mission to promote environmentally responsible energy policies, while generating revenue for the State that can be used to fund other government programs,” said Andrew Dzykewicz, commissioner of the Office of Energy Resources for the State of Rhode Island. “EnerNOC is a valued partner that is helping us to maximize our participation in today’s energy markets and to navigate the evolving demand response landscape.”

“EnerNOC’s continued success with state governments is encouraging, and we look forward to working with the State of Rhode Island to maximize the effectiveness of New England’s energy resources,” said Tim Healy, chairman and chief executive officer of EnerNOC.
