In 2007 and 2008 the construction of the Middletown-Norwalk transmission line disrupted traffic along the Boston Post Road, but the completion of the line is hoped to help provide additional power to lower Fairfield County. In addition a high-voltage undersea line runs from Manressa Island to Long Island to help provide electric power to Long Island Power Authority customers. In 2008 the city government of Norwalk started initial investigations of whether the city might resume generating power for sale to electricity customers in the city.
