State environmental regulators are moving toward a deal that would let Maine’s largest oil-fired power plant skirt the latest pollution controls, igniting a debate over whether the aging facility is a vital energy safety net or an expensive smog-producing relic. The Department of Environmental Protection has issued a draft order for a clean air exemption for Wyman Station on Yarmouth’s Cousins Island. Owned by NextEra Energy, the peaking plant runs mainly when there is high demand for electricity or when other plants go offline. The decision carries consequences for both the region’s energy security and its climate mandates as New England struggles to prevent blackouts during extreme weather while transitioning away from fossil fuels.
