Electric transmission lines provide the transport highways to move electricity from generation sources to electric utilities that service individual homes and businesses. Maintaining a reliable transmission system involves careful long-range planning. Every three years, VELCO, the operator of Vermont's transmission system, must publish a three-year update of its 20-year Vermont Long-Range Transmission Plan. The plan identifies reliability concerns and the transmission alternatives to address those concerns. The Plan also serves as the basis for considering whether alternatives, including new generation and energy efficiency, can meet Vermont's reliability needs. It provides information about transmission projects that may be needed to maintain grid reliability.
