Central Maine Power customers could see a double-digit hike

June 29, 2021 GMT

PORTLAND, Maine (AP) — An increase in federally mandated regional transmission rates will affect nearly every electric utility in New England and will contribute to a projected double-digit increase for Central Maine Power customers starting August 1.

The annual adjustment will result in a 9% increase across the region, according to CMP. The adjustment is used to finance new high-voltage transmission lines and to maintain existing ones, the Portland Press Herald reported Monday.

The Maine Office of Public Advocate said that the increase will likely lead to the largest one-time hike in retail delivery rates for CMP.

CMP has asked the Maine Public Utilities Commission to consider deferring some storm charges and hold an overall residential rate hike to under 10%. For the average customer, that would add $8.65 a month to an $88 bill.

The Office of Public Advocate is seeking more immediate relief and has asked regulators to defer any storm recovery until next year.
