Mary Powell, CEO of Green Mountain Power since 2008, has transformed the company from traditional utility to clean energy pioneer. One of the nation’s few women to lead an electric utility, she was recently named Woman of the Year by an industry trade group. Powell recently confronted a new challenge: cancer. She discusses how undergoing genetic testing and having a double mastectomy earlier this year has changed her outlook on life and work. She also describes Vermont’s energy future beyond “twigs and twine” (electric poles and wires) toward communities powered by small micro-grids, how GMP will be the first utility to offer home batteries made by Tesla Motors, as well as her views on nuclear power, resistance to renewable energy, and her advice to young women entering the work world.
