How would a coal plant be converted to electricity?

Conversion would repurpose most of a coal plant’s assets. Instead of burning coal for the heat, tanks of molten salts would be heated electrically by surplus PV and wind on the grid to “charge” the storage, which could then be “discharged” back to the grid on demand using the former coal plant’s existing power generation and transmission assets.
