Utility Highlights

Efficiency and careful stewardship of electricity resources are central to the philosophy of UI. The electricity utility is making huge strides toward sustainability and social responsibility in all areas of their operation, and for all types of Connecticut residential and business customers.

At UI, sustainability at the heart of everything, from electricity generation to community projects and even choices made about upgrades and changes to the electric infrastructure. In addition, UI helps to administer the Energy Efficiency Fund, an Energize Connecticut partner. UI is improving its efficiency by investing in technology and learning better ways of using its existing equipment.

Here are a few ways this Connecticut utility is reaching out to the community to increase sustainability over a wider area and provide excellent customer service:

  • Increasing education about distributed generation. UI is encouraging local customers to connect their own forms of electricity generation to reduce their reliance on the grid. By educating customers on the ways that solar, wind, fuel cell and micro turbines can help reduce their power costs and support the power infrastructure at the same time, this utility is making it easier for people to decrease their dependency on the electric grid.
  • Electric vehicle infrastructure. Working with both state and local government, UI is streamlining the integration of electric cars into the state of Connecticut. It’s not enough to have electric cars, you also have to have somewhere to charge them—and that’s something UI is building.
  • Outage alerts. UI provides extensive outage alert services , including a real-time online outage map, messaging alerts, and online education resources to help customers prepare for storms and other emergencies.

Coastal areas of Connecticut served by UI can rest assured that they are receiving great service and reliability from a relatively small but experienced utility focused on sustainability.
