Analyst note

Maine residential power was 11th highest of 51 in 2015 at 15.61 ¢ and is 8th in 2024 at 24.29 ¢, so the state moved up 3 places. The U.S. figure went 12.65 to 16.48 ¢ while Maine went +55.6%. The biggest annual move was 2022 at +31.8%; the latest year, 2024, came in at -11.4% against +3.0% for the U.S. Business customers paid 12.47 ¢ in 2015 and 18.22 ¢ in 2024, a gap to homes of -3.14 ¢ then and -6.07 ¢ now; industry went from 9.05 to 12.46 ¢ (+37.7%). Reliability worsened at the 3 Maine utilities that report in both years: their median SAIDI went from 280 minutes in 2015 to 478 in 2024, +71%, against a U.S. median reporter of 99. Central Maine Power Co is the largest by accounts with 657,328, 76.8% of the 855,558 accounts in Maine, and the top three hold 97.7%.

Maine ranks 8th of 51 on residential price (24.29 ¢), among the costliest, and 47.4% over the national average. Since 2015 the residential price moved +55.6% against +30.3% nationally, so Maine has pulled away from the national trend by 25.3 points.
