Sherco coal-fired power plant (largest in Minnesota) will be replaced by solar arrays being constructed on site.
*New* They're adding an iron-air battery to the solar installation to provide power when there's no sun.
PV arrays will produce up to 710 MW, whereas the first Fe-air batteries will be 10 MW. Not the scale needed, but Form Energy just started manufacturing, so this is a pilot of sorts.
