BOSTON, MA  – Eversource’s commitment to enhancing system reliability is significantly reducing the number of power interruptions that customers experience, with outages in the commonwealth down by nearly 17 percent in 2019 compared to 2018. This improvement stems from the energy company’s investments in strengthening and modernizing its electric system, including a program to install more than a thousand smart fuses to the system throughout the commonwealth. These smart fuses can automatically restore power to customers when a tree limb temporarily contacts wires and help to protect the electric system when a problem is detected, such as a current surge or overload.

“Our continued investments in developing a smarter, more resilient, and more flexible grid are delivering direct reliability benefits to our customers and allowing us to reliably and seamlessly connect more clean energy resources onto our system,” said Eversource President of Regional Electric Operations Craig Hallstrom. “Additionally, our commitment to enhancing the electric system throughout the state will help us to reach our goal of being carbon neutral by 2030 and support continued economic growth across the region.”

Eversource has invested more than $2.5 million to install more than 350 smart fuses on its electric system throughout Massachusetts since 2018. The energy company plans to expand the program in 2020 by installing more than 300 devices on the system throughout the state. In addition to its smart fuse program, Eversource will continue to install smart switches, devices that enable system operators to remotely reroute power to customers in minutes. The energy company has installed more than 1,100 smart switches over the last five years and continues to replace utility poles with more durable structures, install hundreds of miles of covered wire, and conduct robust tree-trimming programs to ensure the reliable delivery of energy to customers.

Eversource customers across New Hampshire, Massachusetts and Connecticut all experienced a significant improvement in reliability in 2019. January through December of this year represented the system’s strongest reliability performance across Eversource’s entire service territory since 2013 – the first full year following the merger in 2012 between Northeast Utilities and NSTAR Electric & Gas.
