In a written statement Thursday morning, Gov. Ned Lamont said the current structure “has actively hindered” states’ efforts to phase out polluting power plants in favor of renewable sources like wind turbines and solar panels, while increasing costs “to fix market design failures” in his words. Lamont’s energy policy chief Katie Dykes has emerged as a vocal critic of ISO New England’s structure and priorities, in her role as commissioner of the Connecticut Department of Energy and Environmental Protection. Lamont and his counterparts in Massachusetts, Rhode Island, Vermont and Maine plan to release a “vision document” in their words on Friday through the New England States Committee on Electricity. Connecticut and the four other states outlined a few broad goals that they will hone over the coming months. Those include creating a better market structure and planning process supporting the conversion to renewables; improving grid reliability; and increasing the accountability of ISO New England to the states and by extension their ratepayer households and businesses.
