Wareham Community Electricity Aggregation

Wareham Community Electricity Aggregation Program

Wareham Community Electricity Aggregation is an electricity supply program offered by the Town of Wareham to provide residents and businesses with new, Town-vetted options for electricity supply. Eversource continues to deliver your electricity, repair power outages, and maintain the electricity grid; they also send you one bill for the electricity you used.

On the Wareham Community Electricity Aggregation website (WarehamCEA.com), residents, business owners, and other electricity customers can

  • Learn how the program works;
  • See different electricity products;
  • Easily enroll in any of the program options or leave (opt-out) the program;
  • Read the aggregation plan;
  • See the benefits of supporting renewable energy generation.

Notices about the program:

Please keep in mind that future savings cannot be guaranteed because Eversource Basic Service rates change every six months for residential and commercial customers and every three months for industrial customers.

Newly eligible customers will receive a Customer Notification Letter detailing the program and ways to leave the program (opt out); those who choose not to opt out will be automatically enrolled.

Customers who have chosen a third-party supplier will not receive a Customer Notification Letter and will not be automatically enrolled. They can voluntarily join the program, but they may be subject to penalties or early termination fees from the third-party supplier if they switch to the electricity program during the term of their contract with their chosen supplier.

Most participants in Wareham’s program use “Wareham Standard”, which offers the same renewable energy content as Eversource Basic Service. “Wareham Standard” participants will automatically receive the new program pricing on their December meter read. Due to requirements from the Department of Public Utilities, participants in the 50% and 100% renewable products must affirmatively re-enroll in a product of their choosing to remain in the program. To re-enroll or change your product selection, call Constellation at (833) 461-0813 or complete an enrollment form on the program site: WarehamCEA.com.
