Eversource (NYSE:ES) on Nov. 13 said that construction of a new 3.7-mile, 115-kV electric transmission line is underway and scheduled to be complete by late 2019.
“The Greater Hartford Central Connecticut Reliability Project route passes through portions of Newington, West Hartford and Hartford, along existing Eversource and Amtrak rights of way, as well as under some town streets,” the company said.
The $61m improvement project includes enhancing two local substations and installing the new line, Eversource said.
Eversource Vice President of Project Management Steve Sullivan said in the statement, in part, “This new high-voltage line is crucial to improving power flow in the region and will enable us to reliably serve our customers even during times of high demand, such as a heat wave.”
According to the project’s webpage, the hybrid overhead and underground line is being built between the company’s Newington substation in Newington, Conn., and its Southwest Hartford substation in Hartford. To improve system reliability, cost-effectiveness, and the environment, the company is also upgrading those two substations with new equipment. The webpage added that the project will also allow power to be redirected – for example, north to south – during times of high customer demand.
According to the webpage, construction on the Newington substation modifications started on Oct. 10, and the start of construction on the overhead line – pending all necessary approvals – is scheduled for late 2018.
