The silver lining here is that it make energy storage economical without any subsidies. Looking at local Finnish spot prices - one could charge for 30e/MWh and discharge at 500e/MWh. Companies like GridScale tout 60% round-trip efficiency at a price of 60e/kWh. With such uneven prices, the installation pays for itself within a single year, which is crazy high ROI
