HARTFORD — Ten months after Connecticut Light & Power president and CEO Jeffrey Butler resigned amid mounting criticism over the company’s response to severe storms in 2011, a new CL&P head has been named. William Herdegen III was selected to fill the post, the company announced last month. Herdegen’s commitment to accountability, as well as other characteristics, were stressed in a press release. In addition to structural and infrastructural damage, CL&P’s president/CEO became a casualty of the aftereffects of last year’s Tropical Storm Irene and October 29 snowstorm. The natural occurrences resulted in downed trees and massive power outages that left large portions of Connecticut residents in the dark, and unable to communicate from home, for several days. Many flocked to local libraries and other community gathering places where power was available. Gov. Dannel P. Malloy and state legislators were among those who severely criticized Butler and CL&P for their apparent inability to adequately handle the emergency situation. Herdegen, who has worked in the utility industry for more than three decades, has held a variety of executive positions. He is a former vice president of Kansas City Light & Power. In the CL&P release, Tom May, president and CEO of parent company Northeast Utilities, lauded Herdegen for “a focus on operational excellence, customer service, emergency response and employee safety.”
