Power Supply

The VEC Board of Directors committed to a 100 percent carbon-free power supply starting in 2023. 

VEC can buy power through contracts with counter parties or purchase power through the ISO-NE energy market. Our long-term power supply needs are projected based on forecasts conducted every three years, and, going into each year, our goal is to have contracts in place for at least 90 percent of our projected needs. The remaining power needed is purchased from the spot market. 

Starting in 2017, Vermont’s Renewable Energy Standard (RES) required all Vermont electric utilities to have 55 percent of their power supply come from renewable sources. The renewable requirement increases over time until it reaches 75 percent in 2032.  As the charts below show VEC is exceeding the Vermont RES and is approximately 84 percent renewable and 100 percent carbon free.
