Electricity Cost Increase for CMP Customers Starting July 1, 2016

Starting July 1, 2016, Central Maine Power electricity customers will pay more for grid power.

CMP estimates that the total electricity bill will increase by 4% for small accounts, and 7.6% for medium-sized business accounts. For example, if your current monthly bill is $100, it will increase to $104. If your monthly bill is $1,000, it will increase to $1,076.

Small accounts (peak demand less than 20 kilowatts) will see the following increases:

  • delivery cost per kilowatt hour increases from $0.05404 to $0.059564 (10% increase)

Medium accounts (peak demand greater than 20 kilowatts but less than 400 kilowatts) will see these increases:

  • delivery cost per kilowatt hour increases from $0.002857 to $0.006912 (142% increase)
  • demand charge per peak kilowatt increases from $10.95 to $13.02 for July and August (19% increase), then back down to $12.32 September through June (12.5% increase)

This price increase affects just the delivery portion of electricity bills for customers in CMP’s territory. The cost of the supply portion of the electricity bill depends on whether customers take the standard offer or have a contract with a competitive electricity supplier.
