Katie Dykes, commissioner of Gov. Ned Lamont’s energy and environmental agency, told a Trinity College summit that a “lack of leadership” at ISO-New England on the issue of cutting use of fossil fuels has Connecticut evaluating whether the state should leave the regional power grid. Dykes said ISO-New England’s policies are driving larger investments in natural gas pipelines and power plants that this state “doesn’t want and doesn’t need.” She also said recent Trump administration energy rulings threaten “to punish states for moving away from fossil fuels.”
