Eversource Utility Highlights
Eversource Energy is an electricity customer-focused Connecticut utility combining technology and experience to anticipate and address problems of all types before they become unmanageable crises. Since their merger, they have invested heavily in infrastructure, automation and people to make this electricity utility more reliable than ever, even during major storms.
Eversource has a plan to prevent and manage all sorts of electricity-related problems. Here are a few ways the Connecticut utility is trying to help before little issues become big electricity outages:
- Financial assistance programs. They recognize the importance of electricity for customers across Connecticut, even if they’re having trouble paying their past due or current bills. That’s why they offer customers a variety of financial assistance plans, as well as weatherization assistance to help reduce future bills.
- Real-time outage tracking. They provide real time outage tracking via an their online outage map as well as online account resources for customers to view their specific outage status.
- Equipment inspections. Besides doing hands-on inspections of equipment on the ground, they monitor equipment from the sky using infrared scanning equipment and helicopter fly-over inspections. This way, trained inspectors can quickly identify problematic equipment even in remote areas of Connecticut that might otherwise not be caught until the grid goes down.
- Improving infrastructure. Electrical hardening, involving replacing old copper wires with thick, rubber-coated wires that are more weather and tree-resistant, and structural hardening, which is the installation of stronger power poles and hardware that’s more durable, are just the beginning of infrastructure improvements they have in progress. Automation investments are also helping to monitor the grid for problems so a repair expert can be notified immediately. Along with these improvements, Eversource continues to manage vegetation, including overgrowth and downed trees, to ensure reliable service across its area.
- Sustainable improvements. In recent years, Eversource has committed to making its operations more sustainable. Among these changes, the company attempts to refurbish rather than entirely replace its transformers. With about 2,698 transformers updated to date, Eversource has either recycled or reused about 600 tons of metal and 86,224 gallons of oil. Additionally, their overall operational emissions have decreased by 30% since 2018.
- Renewable energy. Like other utility providers, Eversource is gradually encouraging the use of renewable energy and has started upgrading its infrastructure to accommodate less traditional sources. To date, their initiatives have included installing rapid poles, smart switches and mobile battery systems to enhance electric delivery and reduce outage times; lowering costs for solar energy; expanding its energy-efficient programs to continue decreasing greenhouse gas emissions; and installing EV chargers across its service area.
Customers living in areas of Connecticut served by Eversource can select an alternative energy supplier and get excellent CT energy rates. Eversource will continue to serve customers as the local utility and bill customers in the same manner without interruption in service.
