Energy company investing more than $7.5 million over two years to improve reliability for southside city customers

BERLIN, Conn. – As part of its year-round commitment to provide reliable power to its customers, Eversource is investing more than $7.5 million in 2022 and 2023 for electric distribution system upgrades in the southside area of Waterbury. This year, the enhancement project includes installing nearly 150 stronger and thicker utility poles, approximately 100 new transformers and some 2.5 miles of overhead electric lines known as “tree wire” which can better withstand extreme weather. Also being added are more than a mile of underground lines and ten reclosers high-voltage circuit breakers that detect and mitigate power interruptions. The upgrades and reconfiguration of electric circuits will also allow Eversource to retire and eventually remove a 60-plus year old substation that will no longer be needed.

Crew working

“We work year-round to strengthen the electric system to ensure customers have dependable energy. This project will create several ‘automatic zones’- areas with equipment that can quickly reroute power if there is a problem - which will improve overall electric reliability,” said Eversource President of Electric Operations in Connecticut Steve Sullivan. “By continuing to make strategic investments in the system, like these in Waterbury, we’re building a more robust and resilient electric grid that will serve our customers well into the future.”

The project is underway with crews working Monday through Thursday from 8 a.m. to 3 p.m. – weather permitting. Roads currently affected include Bank, Meadow, Riverside, South Leonard, South Main and Wilson streets as well as Washington and Sunnyside avenues. Roads to be affected later this year include Baldwin, East Liberty and River streets. Eversource will continue to work closely with community leaders and customers where the project is being done to minimize potential impacts to traffic and coordinate with other roadwork happening in the city.  Customers may experience short power interruptions at times during the course of the project so crews can safely perform the work. Any customers affected will be notified in advance by the energy company. The first phase of this project is expected to be finished by the end of December, with all work completed by November 2023.
