Vermont doesn’t get a lot of attention outside of Bernie Sanders, but the state’s power system is worth taking a look at as it has undergone a notable shift toward renewable energy. About 80% of Vermont’s power comes from renewable energy. Almost no fossil-fueled plants operate in the state, other than a handful of peaker units, many of which are on the short-list for closure.
Vermont is part of the ISO-New England market. Vermont doesn’t have a huge load. Interestingly, both the summer and winter peaks are about 1,000 MW. In the summer, the peak typically hits after dark.
