ISO New England reacts to DOE’s order on emergency operation of the Cross Sound Cable

HOLYOKE, Mass., Aug. 16, 2002 — ISO New England Inc., operator of the region’s bulk electric power grid, recently issued the following statement by Stephen G. Whitley, Chief Operating Officer, responding to the Department of Energy’s (DOE) order calling for the use of the TransEnergieUS Cross Sound transmission cable from New England to New York for emergency purposes.

“ISO New England is pleased the DOE recognizes the importance of making the Cross Sound Cable available for power system emergencies through October 1, 2002. This summer’s unprecedented hot weather and sustained weather pattern, as well as the record level electricity usage across New England has compelled ISO New England to consider the use of the Cross Sound Cable during emergency conditions.

“The DOE’s decision to allow access to the Cross Sound Cable by both New England and New York system operators during power system emergencies will provide another resource to maintain the reliability of the two major power systems serving the Northeastern United States.

“During the present heat wave, the fourth of the summer, New England has been a net-importer of electricity from New York, and during our record-breaking hour on Wednesday, August 14, 2002, New England used 800 megawatts of New York-produced electricity to meet demand. And while it is widely believed that power will flow only in one direction on the Cross Sound Cable, it is designed for two-way use.

“ISO New England considers the ability to access the Cross Sound Cable for the purpose of emergency transfers between New York and New England during this period both prudent and appropriate because it will not only reduce the likelihood of service disruption, but it will also minimize the magnitude of any potential outage.

“ISO New England would expect to use the Cross Sound Cable only as a last resort to prevent blackouts in New England. The operation of the Cable may potentially assist New York in times of surplus capacity in New England, but we would not allow the Cable to be used to export electricity from New England if doing so would violate system operating criteria.”

ISO New England Inc. is the not-for-profit corporation responsible for the day-to-day reliable operation of New England’s bulk generation and transmission systems with an installed capacity of more than 27,500 megawatts. In addition to operating the bulk power grid, ISO New England is the administrator of the region’s wholesale electricity marketplace and the Open Access Transmission Tariff on behalf of the New England Power Pool.
