100 MW's of New Demand Response Capacity to Help Prevent New England Winter Blackouts.

BOSTON -- EnerNOC, Inc. announced today that it has made available 100 MW's of new demand response capacity from commercial, institutional, and industrial end-users in response to the Independent System Operator of New England's (ISO-NE) urgent request for up to 450 MW's of demand response capacity needed to help prevent blackouts this winter in New England. The new customers, located throughout the region in Maine, Massachusetts, New Hampshire, Vermont, and Connecticut, now have EnerNOC's award winning technology and services in place to immediately respond to notifications to help preempt blackouts through a combination of load curtailment and onsite generation.

In a filing submitted to the Federal Energy Regulatory Commission (FERC) on November 1, 2005 requesting approval for emergency actions, ISO-NE identified a potential for natural gas shortages and price spikes due to hurricanes Katrina and Rita that pose risks to electrical supply in New England during prolonged periods of cold weather when both gas and electricity usage are highest. ''We're pushing the infrastructure in New England to its limits, both the electric infrastructure and the gas-supply infrastructure," said Gordon van Welie, ISO-NE Chief Executive Officer, in a statement made to the Boston Globe on November 16, 2005.

Consequently, ISO-NE is taking precautions to preempt rolling blackouts and demand response is an invaluable resource for quickly addressing resource adequacy needs. This is not the first time ISO-NE has called upon demand response resources to help preempt blackouts. In a press release issued by ISO-NE, Senior Vice President and Chief Operating Officer Stephen Whitley commented on the state of the grid July 27, 2005, "Today's heat and humidity pushed electricity use to new levels in New England, affecting Southwest Connecticut in particular, where inadequacies in the electricity system make short-term emergency measures necessary. Fortunately, ISO-NE was able to call upon its emergency resources in Southwest Connecticut today to maintain power system reliability in that area."

The winter capacity situation in New England has been covered extensively in reports by The Boston Globe, The Connecticut Post, and New England Cable News, among others. "The call to action has been clear, quick, and emphatic and our customers responded enthusiastically, wanting to preempt possible business disruption and to help the grid. This is an unprecedented response for enabling new resource capacity in such a short period of time and illustrates that customers have a strong propensity to participate in demand response, especially when market rules are properly defined and customer incentives are clear." said Gregg Dixon, Vice President of Marketing and Sales for EnerNOC.

David Brewster, EnerNOC's President and Co-founder, commented, "FERC's expeditious approval of this program will give customers the confidence to continue to participate in demand response markets, spurring the continued rapid growth of an essential resource in balancing today's electrical supply and demand equation."

EnerNOC customers participating in the ISO-NE's Supplemental Winter Demand Response Program include telecommunications companies, data centers, universities, industrial facilities, hospitals, insurance companies, municipalities, state government facilities, amongst others. In total, these new customers are ready to contribute more than 100 MW's of electrical capacity that will be available for real-time response to operating capacity deficiencies in New England.
