Europe’s deepest mine to become giant gravity battery

  • They were actually planning pumped storage there earlier, with a claimed capacity of 530MWh https://yle.fi/a/3-12593341

  • Interesting. Earlier they were planning pumped storage there, with a claimed capacity of 530MWh https://yle.fi/a/3-12593341 Seems like that fell through https://www.epv.fi/en/project/a-pump-storage-station-for-pyhasalmi-mine/

    Every source I can find says "2MW" of capacity. I assume they meant 2MWh, though that doesn't sound like that much.
