Program Implementation Process


Implementing a municipal electricity aggregation like the Green Worcester ElectriCITY Municipal Aggregation Program is a regulated process that is overseen by the Massachusetts Department of Energy Resources (DOER) and the Massachusetts Department of Public Utilities (DPU). The implementation process took many months to complete because of the time required for the DOER and the DPU to review and approve Worcester’s implementation plan for the program. Key steps are outlined below.

Timeline illustrating the steps in the program implementation process. Process explained below.


City Council vote: Worcester had to vote publicly to pursue aggregation.

  • The City Council authorized the pursuit of aggregation on June 20, 2017.

Aggregation Plan development and public review: The City was required to develop an Aggregation Plan, a broad authorization document and program template that demonstrated how Worcester would meet regulatory requirements. The plan had to be presented at a public meeting and available for the public to comment on.

  • Worcester’s Aggregation Plan was presented at a public meeting on February 20, 2019.

Regulatory review: The City was required to submit an Aggregation Plan document to the Massachusetts DOER for review and then to the Massachusetts DPU for approval.

  • Worcester’s Aggregation Plan was reviewed by the DOER on March 12, 2019. The plan was submitted to the DPU on March 15, 2019, and approved on September 30, 2019.

Choosing an electricity supplier and signing an electricity supply contract: Once the State regulatory review process was completed and the Aggregation Plan received formal approval by the state, the City implemented a public procurement process to select and sign a contract with an electricity supplier. During this process, program details were finalized, including the amount of renewable energy, above the amount required by state law, the amount of renewable energy in any program options, and the price for each option.

  • Worcester signed a 34-month contract with Direct Energy on October 22, 2019. The contract term was from the February 2020 meter reads through the December 2022 meter reads.

Public engagement and education: In fall of 2019, once the electricity supply contract had been signed, the City conducted a public engagement effort to inform the community about program details and the ability to opt out. This effort included mailing a letter to each electricity account holder on National Grid’s Basic Service who would be automatically enrolled in the program if he/she did not opt out. The public engagement effort also included a press release, public information sessions, and outreach to community groups throughout the City.

Program launch: In February 2020, the program launched, and electricity accounts were enrolled as of the February 2020 meter reads. Worcester electricity customers first saw Worcester’s price on their March 2020 National Grid electric bills.

Program operation: Now that the program is up and running, new electricity accounts in Worcester will be eligible for automatic enrollment within a few months of being opened. (Automatic enrollment is state law.) Learn more about enrollment.
