Central Maine Power is bringing back its CEO from the 1990s with a stated mission to “restore public trust” in the embattled company. Maine’s largest utility announced Wednesday morning that it had appointed David Flanagan to serve as the executive chairman of its board of directors. Flanagan led the utility as its CEO from 1994 to 2000, a period that included prolonged power outages following the ice storm of 1998. The new hire comes as CMP has taken numerous hits to its reputation in the past few years and recently received the lowest score on a national ranking of customer satisfaction with electric utilities.
