Teamwork Between Millstone and Connecticut Light & Power Helped Power the Region Throughout Blizzard

Teamwork among several New England Council members–Dominion, Connecticut Light & Power (a Northeast Utilities company), and ISO-New England–helped keep the power on in the region throughout this week’s historic Blizzard.  Dominion’s largest generation facility in New England, Millstone Power Station, generated electricity for Connecticut and the region throughout this week’s blizzard as a result of planning, communication, and teamwork with Connecticut Light & Power (CL&P), the local utility, and the regional grid operator, ISO-New England.

Millstone, located in Waterford, CT, experienced two feet of snow with more than 50 mph wind gusts.  Together, Millstone’s two reactors generate 2,100 megawatts of electricity, upwards of 50 percent of Connecticut’s power needs.  Throughout the storm, both reactors operated at 100 percent power.

In preparation for the blizzard, Millstone tested its safety systems, brought in back-up generation and secured the site for difficult weather conditions.  Additionally, approximately 200 Dominion personnel were sequestered on site at Millstone or in its emergency operations facilities.  Personnel were pre-staged at the emergency facilities in the event that they were required to activate the Station’s emergency response organization.

During the storm, Millstone’s operators were in frequent communication with CL&P, and ISO-New England, to ensure safe and reliable power.

“Weather conditions throughout the region were shared real-time, forecasts were reviewed, and both potential and actual challenges were discussed to ensure the electric grid conditions were understood from a reliability and generation capability perspective,” Mark Goolsbey, manager of Operations, Millstone Unit 2, said. “This was particularly helpful during the preparations, as the generating stations were able to share insights and CL&P and ISO New England were able to assess and share their readiness to respond to the needs of each station.”

“I commend our employees for their work during the blizzard to support the uninterrupted operation of the Millstone Power Station and electric reliability for all our customers,” said CL&P President Bill Herdegen.  “This is an example of the outstanding communication and superior customer service that are integral to our overall mission of improved storm response.”

The New England Council thanks these members for their service to the region during a challenging week for residents and businesses alike.
