Eversource Energy has participated in a number of projects to improve the reliability of the [[power grid]] in southwest Connecticut.  The first project was construction of the $350 million 345 kilovolt Bethel–Norwalk transmission line through the western part of the state, and was constructed entirely by the company when it was still known as Northeast Utilities.

With [[United Illuminating]], an upgrade to the 69-mile (112&nbsp;km), 345 kilovolt Middletown-Norwalk transmission line was energized in 2009 at a cost of $900 million.

In 2013, the Greater Springfield Reliability Project, a component of the ongoing New England East-West Solution, was energized at a cost of $795 million. The project addressed numerous reliability issues with the Springfield, MA area's 115 kV transmission system by constructing two new 345 kV lines to the Agawam substation; one line north to Ludlow and the other south to North Bloomfield, Connecticut.

The new 345 kV corridor added a new strong interface between Massachusetts and Connecticut. The project also involved rebuilding all of the 115 kV lines along the transmission corridor between South Agawam and Ludlow to increase their capacities, building a new 115 kV transmission substation in East Springfield (Cadwell), replacing the Fairmont 115 kV transmission substation in Chicopee with a new substation across the street, and configuring a new 115 kV line from South Agawam to Southwick using a combination of both new and old line segments of the former 115 kV path between Agawam and North Bloomfield. The new Cadwell and Fairmont switching stations allowed a number of three-terminal 115 kV lines to be broken up into two-terminal lines. Finally, the project allowed a problematic underground 115 kV transmission path through the city of Springfield that was vulnerable to thermal overloads to be removed from service by breaking it in half at the middle. The underground lines now function solely to supply the distribution load served out of the Breckwood substation in Springfield. A previously proposed costly project that would have replaced the underground cables is no longer necessary. On November 20, 2013, cutover of 115 kV lines to the new Fairmont Switching Station was complete, marking substantial completion of the GSRP.

Eversource has taken action to support the use of [[electric vehicle]]s. Starting in 2018, the company began spending $45 million over five years to install over 400 electric vehicle charging stations in Massachusetts. The project is part of the company's Grid Modernization plan. The company has switched much of its power source from coal to [[natural gas]], wind, [[hydroelectricity]] and solar power.<ref>{{Cite news|url=https://www.masslive.com/business-news/index.ssf/2018/08/eversource_rolls_out_electric_car_charge.html|title=Eversource begins rollout of 400 electric car chargers across Massachusetts; 'range anxiety' seen as enemy to emissions progress|work=masslive.com|access-date=2018-11-28|language=en-US|archive-date=2018-11-28|archive-url=https://web.archive.org/web/20181128122929/https://www.masslive.com/business-news/index.ssf/2018/08/eversource_rolls_out_electric_car_charge.html|url-status=live}}</ref>
