The US built coal plants in the 1990s and even in the 2010s. These last ones started construction in roughly the years 2003-2008, when US natural gas prices were elevated and (many thought) due to go up even more:
Coal's brief renaissance was halted by a triple-whammy of lower gas costs (from shale), lower wind costs, and lower solar costs. It's soon to face another whammy: falling grid scale battery costs. I don't think that the continental US will ever build another coal generating station. But that happened more recently than 1980.
