Change your program option

Please note: Nantucket PowerChoice will transition to a new electricity supplier and new pricing with May 2020 meter reads. Because of this transition, changes from one program option to another will be effective with May 2020 meter reads.

If you are already enrolled in the program, you may use the form below to:

  • Opt up to PowerChoice Green – 12.232 ¢/kWh
  • Change back to PowerChoice (this is the default program option) – 11.300 ¢/kWh

Please note that it may take up to two billing cycles for the change to appear on your bill, as changes can only be made at the start of a billing cycle.
