Vermont Electric Power Company (VELCO) is a transmission-only utility operating the high-voltage electric grid in Vermont. Founded in the mid-20th century, it coordinates bulk transmission, interconnections with neighboring transmission operators, and system planning. VELCO plays a central role in regional reliability, wholesale power access, and integration of renewable energy resources within the ISO New England footprint.
VELCO was incorporated in 1956 amid post-World War II expansion of the North American power grid and the rise of regional transmission planning associated with entities such as the New England Electric System and the Northeast Utilities. Early projects included construction of 115 kV and 345 kV corridors connecting substations near Vermont Yankee, Burlington, and Brattleboro. In the 1970s and 1980s VELCO participated in regional reliability initiatives linked to the Federal Energy Regulatory Commission policies and coordinated operations with Hydro-Québec, New York Independent System Operator, and ISO New England. The company expanded transmission capacity to support natural gas-fired generation, hydropower imports via Canadian energy interties, and later the integration of wind power and solar power resources that emerged during the early 21st-century renewable energy transition.
VELCO is organized as a transmission-only entity owned by a consortium of Vermont distribution utilities, resembling joint-action agencies like the Electric Reliability Council of Texas in structure but distinct in scope. Its board and executive leadership liaise with state institutions such as the Vermont Public Utility Commission and interacts with federal bodies including the Federal Energy Regulatory Commission and the North American Electric Reliability Corporation. Governance emphasizes coordination among owners such as Green Mountain Power, municipal utilities, and rural electric cooperatives, aligning transmission planning with regional planning bodies like ISO New England and policy directives from the Vermont Agency of Natural Resources and the Vermont Agency of Commerce and Community Development.
VELCO operates a statewide high-voltage network of 345 kV, 230 kV, and 115 kV transmission lines, substations, and switchyards linking major nodes such as Highgate, Burlington Electric Department, and Windsor. The system includes interconnections to New Hampshire and New York transmission systems, as well as international ties to Canada via Hydro-Québec TransÉnergie. Infrastructure elements include steel lattice towers, monopoles, series compensation, and synchronous condensers similar to upgrades undertaken in other regions like PJM Interconnection and California ISO. Protection systems, SCADA control centers, and supervisory communications employ technology standards promoted by North American Electric Reliability Corporation and IEEE technical committees.
VELCO provides open access transmission service consistent with Federal Energy Regulatory Commission Order 888 and engages in planning under ISO New England market rules. Operational responsibilities include system dispatch coordination, outage scheduling, voltage support, reactive power management, and emergency response compatible with NERC reliability standards. The company conducts power flow studies, contingency analysis, and real-time situational awareness using energy management systems comparable to utilities such as Con Edison and Entergy. VELCO also offers transmission planning, interconnection studies for independent power producers, and coordination for demand response programs run by distribution owners like Green Mountain Power.
Projects have required environmental review under Vermont statutes and federal statutes analogous to National Environmental Policy Act processes, involving assessments of impacts on Vermont's Green Mountains, wetlands, and wildlife habitat. Regulatory proceedings before the Vermont Public Utility Commission and federal agencies have addressed siting, routing, and mitigation measures, often involving stakeholders including the Audubon Society of Vermont, landowners, and municipal governments. VELCO has worked to mitigate impacts through design modifications, vegetation management plans, and permitting tied to Endangered Species Act considerations and state environmental regulations administered by the Vermont Department of Environmental Conservation.
Significant initiatives include statewide transmission reinforcements, reliability upgrades to accommodate the Chittenden County load growth, and rebuilds of critical corridors to reduce congestion similar to upgrades pursued by NYPA and Bonneville Power Administration. Notable projects have tied into regional initiatives such as the Seabrook Station import capability, cross-border energy transfers with Hydro-Québec, and upgrades enabling integration of utility-scale wind farm projects like those developed in Franklin County and Rutland County. VELCO has implemented advanced conductor technology, substation automation, and grid-modernization pilots comparable to programs by U.S. Department of Energy demonstration projects.
The company manages storm response and restoration for events such as major ice storms and windstorms historically affecting New England, coordinating mutual assistance with entities like American Public Power Association crews and regional mutual aid under NERC guidelines. Outages caused by vegetation contact, equipment failure, and extreme weather have prompted system hardening projects and increased vegetation management in collaboration with local utilities such as Burlington Electric Department. Reliability performance is reported in coordination with ISO New England metrics and subject to standards from North American Electric Reliability Corporation and Federal Energy Regulatory Commission oversight.
VELCO engages municipalities, landowners, conservation organizations, and economic development agencies including the Vermont Economic Development Authority to address siting concerns and convey economic benefits of transmission investment. The company supports workforce development initiatives linked to trade organizations like the International Brotherhood of Electrical Workers and partners with educational institutions such as the Community College of Vermont on training. Transmission investments facilitate access to wholesale markets that affect rates for distribution owners like Green Mountain Power and municipal utilities, and contribute to statewide goals for renewable energy and resilience overseen by the Vermont Department of Public Service.
