Prices

The Green Worcester ElectriCITY Aggregation Program includes two options. The Commonwealth of Massachusetts requires that all electricity supply products include a minimum of 59.2% from renewable or clean energy resources in 2023. Both of the Green Worcester ElectriCITY Aggregation Program options exceed the minimum requirement by purchasing additional locally produced renewable electricity.

  • Worcester Standard Green (default / automatic enrollment): New participants will be automatically enrolled in Worcester Standard Green and receive an additional 30% of their electricity from premium renewable energy resources in the New England region, in addition to the minimum required by law.
  • Worcester 100% Green (option available by request): Worcester 100% Green lets you choose 100% renewable energy and also make a local impact. Not only do you receive 100% of your electricity from renewable sources, you also receive all of your electricity from within the New England region. Your choice helps to build demand for more renewable energy on our local power grid, which helps to green our grid.

If you participate in the Green Worcester ElectriCITY Aggregation Program, you will see Green Worcester ElectriCITY listed on your National Grid electric bill as your electricity supplier. See an example National Grid bill.
