The freak October snow storm resulted in power outages throughout Connecticut.
Northeast Utilities says Jeffrey Butler has resigned as president and chief operating officer of Connecticut Light & Power, which has come under fire for its handling of power outages after last month's snowstorm.
NU officials say Butler resigned Thursday because remaining on the job would be a distraction.
Butler and others at CL&P were criticized by customers, state officials and members of Connecticut's congressional delegation for perceived delays in restoring power after last month's storm, which resulted in massive power outages to as many as 830,000 customers.
Outages persisted for as long as 11 days.
Butler joined Berlin-based CL&P in 2009 after 27 years Pacific Gas and Electric Company (PG&E) in San Francisco.
