VELCO manages the safe, reliable, cost-effective transmission of electric power throughout Vermont and as a part of the integrated New England regional network. This requires us to maintain our existing system including our facilities and more than 13,000 acres of rights-of-way; to plan for the future needs of Vermont and New England electric customers; and to construct upgrades when needed for system reliability or growth. In addition, we constantly seek ways that innovative solutions and technology can make us more affordable, effective, and more efficient at being a trusted partner in grid solutions.

Northeast blackout
The 2003 Northeast blackout was a widespread power outage that affected parts of the northeastern United States and Canada on August 14, 2003. The blackout, one of the largest in history, left approximately 50 million people without electricity for several hours. It was triggered by a series of cascading failures in the electricity grid, highlighting vulnerabilities in the system and prompting efforts to improve its reliability and resilience.

VELCO Projects
The Franklin County Line Upgrade is a VELCO proposed project to rebuild the power line from VELCO's Georgia Substation.
This upgrade is needed because a recent conditions assessment revealed deficiencies within the substation.
VELCO proposes to construct a replacement substation to the north and adjacent to the existing substation.
