(May 7, 2026) — As part of its commitment to transparency with customers and year-round efforts to deliver safe, reliable power through critical maintenance and investments that strengthen the resiliency of the electric system, Eversource is providing municipalities with their annual electric reliability scorecards – a town-by-town snapshot of the energy company’s performance in Connecticut. As the scorecards demonstrate, Eversource’s electric reliability has greatly improved and customers have experienced significant benefits due to continued investments in the distribution system and vegetation management over the past ten years, including:
Months Between Power Interruptions: System reliability continues to strengthen, with the average customer now experiencing one interruption every twenty months, representing a 15% improvement since 2017.
Electric System Automation: Continued investments in distribution system automation in outage monitoring systems and field technology – 42% of customers affected by an outage in 2025 were restored within five minutes, significantly reducing disruption and improving customer experience.
Avoided Outages: Eversource estimates that more than 1.5 million customer interruptions were avoided across the state in 2025 as a result of investments in distribution system automation.
“These scorecards help our customers understand how outages impact their area while highlighting some of the critical work we do every day to strengthen our electric system and make it more resilient,” said Eversource Vice President of Electric Field Operations Don Scacco. “Throughout the year, we use this comprehensive reliability data along with strategic cost-benefit analyses to identify where improvements to the system are needed and make targeted investments – like installing automated technology or conducting enhanced tree trimming – that help to reduce outages and restore power faster for customers. These scorecards are a clear demonstration of how our everyday efforts to bolster the grid make a tangible difference for customers while also providing real insight into the progress that still needs to be made so that we don’t leave any customer or community behind. That’s why it’s essential that we continue investing in the system and building on local successes so customers can continue experiencing the increased reliability they’ve benefitted from over the last decade, which is fundamental to the success of our communities, economy and state as a whole.”
Through insightful local data, the annual electric reliability scorecards break down the primary causes, duration and frequency of power outages in each of the 149 municipalities Eversource serves, allowing communities to see how they compare to the statewide average. The scorecard data also includes information on the energy company’s investments in system reliability and resiliency projects locally, showcasing how strategic grid upgrades result in direct benefits for customers – improving quality of life for residents and productivity for businesses.
Eversource works continuously to make critically needed investments in the electric system across the state – replacing aging utility poles, electric lines and other materials with stronger, more modern equipment that can better withstand severe weather, including the installation of automated technology like smart switches. These automatic switching devices can identify the location of a power outage when it happens, isolate the area on the system, and then re-route power to customers. By ensuring there is more than one path for electricity to reach homes and businesses, smart switches can significantly reduce the duration of outages and the overall number of customers affected. Last year, Eversource estimates that more than 1.5 million customer interruptions were avoided across the state thanks to automated technology. These improvements, in addition to the energy company’s comprehensive vegetation management work, have led to increased reliability for customers across Connecticut over the last decade:
