New England power system update

Holyoke, MA—October 31, 2012— The region’s utilities continue to make progress in restoring service to customers who lost power during Hurricane Sandy, with power outages in New England declining to fewer than 700,000 in the early afternoon of Wednesday, October 31, down from a peak of about 1.3 million customers on Monday night.

Power system reliability was maintained through the storm and its aftermath, even with the loss of several power plants and more than 50 high-voltage transmission lines. ISO New England Inc., the operator of the region’s high-voltage power system and wholesale electricity marketplace, is working closely with the transmission and generator owners and operators to maintain reliability as they bring the affected generation and transmission back into service.

The ISO also continues to coordinate with neighboring power systems in New York and Quebec, and New Brunswick, Canada.
