If downgrading from power generation to power storage is an acceptable outcome, it would be more efficient to decommission the turbines along with the coal boiler, and just plug a large battery into the remaining transmission infrastructure.

This would be much more economically effective for longer term (like, ~1 week) storage than batteries. The round trip efficiency could be increased by adding a gas turbine topping cycle.
