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.
The current plan: 2015 Vermont Long-Range Transmission Plan
On June 25, 2015, following a public input process that began in January, VELCO filed the 2015 Vermont Long-Range Transmission Plan. The plan contains the most current forecast of electric load and extensive discussion of major trends influencing Vermont's grid, and identifies projected needs for infrastructure projects on the transmission and subtransmission systems.
