Important program news:

Prices for the Green Worcester ElectriCITY Municipal Aggregation Program will change and move lower in December, when the current electricity supply contract with Direct Energy Services, LLC ends and a new, 24-month contract with Direct Energy takes effect. The new prices for each option are as follows:

  • Worcester Standard Green – 16.31 cents/kWh: This option includes an additional 40% renewable electricity from new renewable energy projects in our region (MA Class I RECs) above the state minimum requirement. This is a 10% increase in renewable energy resources from the current contract. Most participants are enrolled in Worcester Standard Green.
  • Worcester 100% Green – 17.73 cents/kWh: This option includes 100% renewable electricity from new renewable energy projects in our region (MA Class I RECs).

Both prices are below National Grid’s 9-month winter residential price of 18.213 cents/kWh, which takes effect November 1, 2023. Because National Grid’s price will change in August 2024, savings after this date cannot be guaranteed.

No action is required for current Green Worcester ElectriCITY participants. All active program participants will continue to be enrolled in the program, with the price change taking effect for their December 2023 meter read.

As a Worcester resident, you can opt to purchase your electricity supply through our Green Worcester ElectriCITY Municipal Aggregation Program. It’s like purchasing your electricity supply from a warehouse club—the City purchases New England-based renewable energy in bulk and passes on any potential savings to you.

The program offers price stability for the contract term. However, since National Grid’s prices will change and future prices are unknown, our aggregation program cannot guarantee savings. You may opt out of the program at any time, without penalty.

Worcester Standard Green – an additional 40% from new regional renewable resources (MA Class I RECs)

  • New price: 16.31¢/kWh (December 2023 – December 2025)
  • Current price: 16.912¢/kWh (August – December 2023)

Worcester 100% Green – 100% from new regional renewable resources (MA Class I RECs)

  • New price: 17.73¢/kWh. (December 2023 – December 2025)
  • Current price: 18.763¢/kWh (August – December 2023)

National Grid’s residential Basic Service supply price from November 2023 – July 2024 is 18.213 ¢/kWh. Pricing beyond July 2024 is not yet set and will vary with the market. In contrast, prices for the Green Worcester ElectriCITY Municipal Aggregation Program have been set through December 2025. See a detailed price comparison here.


Am I already in the program?

Check the Supply Services portion of your recent National Grid bill. If “Green Worc ElectriCITY Aggregation Prog” is listed as your electricity supplier, you’re all set. Once you’re in our program, there’s no need to do anything, unless you choose to opt out.


How green is the electricity supply?

Worcester Standard Green is the default option, but you may upgrade to Worcester 100% Green at any time. Whichever option you choose, more than half your electricity will come from new renewable energy projects in the New England region. Our contract with Direct Energy more than doubles the state required minimum of electricity you receive from new renewable resources in the New England region. And we’ve done a thorough vetting process to ensure that the supply meets our standards and comes from reliable sources. If you select the 100% Green option, all of your electricity will come from new renewable resources in the New England region.

What if I change my mind and want to go with another supplier?

No problem! You can opt out of the program at any time, with no penalty. You can also rejoin Green Worcester ElectriCITY’s power supply at any time. Please note, however, depending on market conditions, if you rejoin the program at a later date, the program price is no longer guaranteed, and you may be charged a different price than current Green Worcester ElectriCITY customers.


If I participate, what stays the same?

National Grid is still your electric utility. They will continue to deliver your electricity, be responsible for managing power outages, and bill you. Your National Grid invoice is the only electric bill you’ll receive, and it will include supply charges for Green Worcester ElectriCITY.


So, why should I participate in the Green Worcester ElectriCITY Municipal Aggregation Program?

  • More than half to 100 percent of your electricity comes from guaranteed, vetted, new renewable energy resources in the New England region.
  • No surprises in your electric bill. Rates remain fixed for the contract term.
  • Opt out at any time with no penalty.
