And the town was still growing. In 1957 the increasing tempo of business prompted the town to approve a $5 million bond issue to build a new generating plant. Completed in December 1959, the new plant was named after Norton P. Potter, an outstanding citizen who served as an Electric Light Commissioner from 1909 to 1955. In the late 1960s, the increasing demand for electric power made it impractical for BELD to continue generating all of the town's power needs 365 days a year. In late 1967, BELD established an intertie with Boston Edison. This allowed the town to purchase power when needed, and to sell excess power when possible.
