Eversource Energy has canceled the Central Connecticut Reliability Project that was designed to enhance transmission reliability in New England, an Eversource spokesperson told TransmissionHub on Nov. 12.

The project was a 36-mile, 345-kV transmission line planned to extend from Frostbridge, Connecticut, to North Bloomfield, at a cost of about $350 million, according to TransmissionHub data. It was one of four projects to make up the New England East-West Solution, and it had been on hold for some time following studies by ISO New England.

In its 2014 study on the Greater Hartford and central Connecticut region, ISO New England concluded that various 115-kV upgrades to address local reliability concerns in Hartford and issues associated with imports into western Connecticut could replace the project.

The reliability needs previously identified for the project “are being more effectively addressed through smaller, more targeted projects in several areas throughout east/south/central” Connecticut, the Eversource spokesperson said. Those projects, which include the Frostbridge to Campville Project, are being proposed to help meet growing demand for electricity, he said.

Another project that is part of the NEEWS, the 345-kV Interstate Reliability Project, is nearing completion and is on schedule to begin service by the end of the year, the Eversource spokesperson added.

That 75-mile project is estimated to cost about $525, with Eversource responsible for a 38-mile portion from Killingly, Conn., to Card Street, Conn. National Grid is building the other part of the line, which originates in Millbury, Mass., and extends south and west to connect with the Eversource portion in Connecticut.

“We’re getting things tested and ready to go,” a National Grid spokesperson said when asked about the planned in-service date. The companies intend to energize the entire line at once in the middle of December, he said.

In early November, an Eversource official said that the company’s portion of the project would carry a final cost of $218 million. Work on the Eversource portion was 99.5 percent complete, Jim Judge, Eversource executive vice president and CFO said during a conference call on 3Q15 earnings.
