Greater Hartford - Central Connecticut Reliability Project
Eversource is proposing to construct a new 115-kilovolt (kV) transmission line in the Greater Hartford and central Connecticut area. These improvements will strengthen our system and enhance our ability to reliably serve electrical demand, in keeping with national and regional reliability standards.
The 3.7-mile hybrid overhead and underground line would be constructed between our Newington substation in Newington, Connecticut, and our Southwest Hartford substation in Hartford, passing through portions of Newington, West Hartford and Hartford. The new line would be located within Eversource's existing transmission and distribution line rights of way, under town streets and along the existing Amtrak rights of way.
To improve system reliability, cost-effectiveness and the environment, we will also be upgrading our Newington and Southwest Hartford substations with new equipment. The project will also allow power to be redirected – for example, north to south – during times of high customer demand.

Regional Open House Events
A regional open house was held in West Hartford on January 20, 2016, and a second regional open house was held in Newington on April 27, 2017. The open houses gave local residents and business owners an opportunity to learn more about the project, ask questions, and provide comments on the proposed project with subject matter experts from Eversource.
Connecticut Siting Council
Involving the public and municipal leaders is an important part of the project’s planning process. For an electric transmission line project, such as the Greater Hartford - Central Connecticut Reliability Project, the Municipal Consultation and Application Filing phases are part of the regulatory review process, as defined by the Connecticut state statutes.
The statutes require that an applicant for a new electric transmission line provide certain information on the proposed project to municipal officials in communities affected by the proposed transmission route, and to seek input from each municipality before the filing of an application.
To learn more about the siting process, visit the CSC website.
CSC Public Hearing
A CSC-sponsored public hearing is being held to give local residents, business owners and other stakeholders an opportunity to ask questions, and provide comments on the proposed project.
Public Hearing Schedule:
Thursday, August 22, 2017
3 p.m. - Evidentiary Session
6:30 p.m. - Public Comment Session
(Please note: both sessions are open to the public)
Newington Town Hall Auditorium
131 Cedar Street

On June 7, 2017, Eversource applied to the CSC for a Certificate of Environmental Compatibility and Public Need (Application) for the construction of the Greater Hartford – Central Connecticut Reliability Project.
Municipal Consultation Filing
The Municipal Consultation Filing (MCF) was submitted to the towns of Berlin, Newington and West Hartford, and the city of Hartford, on December 18, 2015. The MCF provides project information, including the public need, site selection process, maps, analyses of alternate sites/routes, schedule and environmental effects of the proposed project.
In order to facilitate the MCF process, Eversource offers to meet with the chief elected and other officials of each affected municipality to explain the proposed project and provide information on the proposed project route, including the route selection process and the environmental effects, among others.
