NRG Energy, a New Jersey-based energy company, announced on Monday that it was selling 4.8 gigawatts worth of “non-core fossil assets” to a subsidiary of Boston-based ArcLight Capital Partners for $760 million. Schrader said NRG needs to have more discussions with ArcLight about their plans for the Middletown plant, where NRG has been working to gain regulatory approval and funding to replace two half-century-old turbines with one new turbine. The state’s Department of Energy and Environmental Protection will hold an informational hearing over Zoom at 3 p.m. Wednesday on NRG’s applications for permits to operate the proposed new turbine. The planned turbine was not meant to run all year, but to fire up quickly in order to meet peak energy demands in the winter and summer, NRG has said. Battery storage would serve the same need without burning natural gas or other fossil fuels, opponents of the new turbine reasoned.
