Central Maine Power Co. (CMP), a subsidiary of Avangrid Inc., is reminding its customers that the energy supply rates for residential customers who choose Standard Offer supply will rise 13.7% beginning in January.

Doug Herling, president and CEO of CMP, wants its customers to know that this “is not a CMP increase — this is the increase in the cost of the energy supplied largely by natural gas-fired generation companies. However, CMP collects this fee in bills and remits it to the Standard Offer suppliers, so customers often assume we have just raised their rates — which is not the case.”

Beginning in January, residential customers will receive a brief explanation in their bills about how the price of their supply of energy is different than the price of delivery, which is the portion CMP is responsible for. Says Herling, “We want to do everything we can to prevent the sticker-shock that some customers experienced a year ago when the supply rates rose by close to 18% and were first reflected in customer bills during an extreme cold spell in January.”

CMP charges customers for the delivery of electricity and all customers share in transmission and distribution costs – essentially the costs involved in maintaining the grid. The Maine Public Utilities Commission determines the rates for Standard Offer Service energy supply and announced the 2019 rate increases in December. Customers can choose to receive energy supply from other providers; a listing of licensed retail suppliers is available on the Maine Public Utilities Commission website.
