The Rate Board below allows residential and business customers to compare Eversource and UI Standard Service generation rates with those offered by licensed suppliers and registered aggregators.

Switching to a Licensed Generation Supplier

  • You are not required to switch – you can remain with Eversource or UI for your generation supply service.
  • Regardless of which supplier you choose, Eversource or UI will still deliver your electricity, bill you for service, and respond to power outages. Only Eversource or UI can terminate your service.
  • Protect account information like you would your Social Security or credit card numbers.
  • Showing your bill to anyone, like during a door-to-door sale, reveals your personal account information.
  • Switching your generation service can only occur on your meter read date.  Enroll at least ten business days before that date.

Working with an Electric Aggregator

  • Electric aggregators gather customers to negotiate a generation rate with suppliers on their behalf. 
  • Electric aggregators offer an alternative for customers who may wish to have the aggregator shop for you. 

Standard Service

  • Standard Service is the supply option provided by Eversource and UI.
  • Standard Service rates change on January and July 1st and are fixed for six months.
  • Contact Eversource or UI directly to be immediately returned to Standard Service.
