More than 115,000 Central Maine Power Company customers were without power this afternoon and that number is expected to climb even higher as Tropical Storm Irene rampages through the state.

John Carroll, CMP spokesman, it could be several days before electrical service can be restored to those customers.

“Customers should be prepared for some extended outages. This is obviously a significant storm,” Carroll said.

York and Cumberland counties were hardest hit, with 32,500 and 27,250 customers outages reported in those counties. Kennebec County had 6,100 outages.

By comparison, a snowstorm in February of 2010 knocked out power to 220,000 CMP customers.

Carroll said crews will work through the night tending to downed wires, with a full blown restoration effort set to begin at 5 a.m. Monday.
