And yet it's still far cheaper than any other form of seasonal storage.
Seasonal storage is crazy expensive. You need a lot of power, and a lot of energy, but you can only amortize the cost over one or two usages per year.
Norway already have seasonal storage with a storage capacity equivalent to 6-8 months of total electricity use in the form of its existing hydroelectric plants, with no need to pump things back up again.
