Central Maine Power (CMP) has requested a temporary rate hike for approximately 670,000 customers in southern and central Maine. The utility is seeking a $69.3 million increase to fund critical grid investments and reliability projects while the Maine Public Utilities Commission deliberates on a larger $189 million rate case.

If approved, the temporary increase could raise monthly distribution costs by an average of $7 per household as early as this fall. A final decision regarding a larger rate hike, which could increase monthly bills by $18, is expected next spring. The request follows a downgrade of CMP’s financial outlook to ‘negative’ by S&P Global Ratings, citing a $100 million cash flow deficit and stagnant revenue.
