Shuttering fossil fuel power plants may cost less than expected – study

WNM | Dec 7, 2020 at 10:52 AM

Decarbonizing US electricity production will require both construction of renewable energy sources and retirement of power plants now operated by fossil fuels. A model suggests that most fossil fuel power plants could complete normal lifespans and still close by 2035 because so many facilities are nearing the end of their operational lives.
