FirstLight Power gathered company and local officials at its power generation station along the Quinebaug River Wednesday to announce it is retiring the last remaining fossil-fueled plant in its system in May 2023 to be replaced with renewable battery facility. The new system still needs state permits and a connection agreement with ISO-New England, which manages the electric grid in all six New England states, Barton said. Construction will take about two years, and the battery facility is expected to become operational in 2024 or 2025. The new battery plant also will be a peak-period only power generating facility and will be co-located at the Tunnel Dam 3-megawatt hydropower plant in Preston. Operation Fuel also runs a job training program to train people for the growing clean energy industry.
