investment logic of pumped storage

Can Norway be the battery of Europe?

Norway''s extensive hydro system lacks the flexibility needed to balance European electricity markets. Norway''s electricity system is primarily driven by its extensive hydro-electric resources – over 93% of Norway''s electricity generation is from hydro. At the beginning of 2021, there were 1,681 hydropower plants in Norway, with a ...
