I'm pretty sure this is done at a large scale in both Norway, Sweden and Switzerland. While storing energy have always been a huge problem, I'm surprised this is not more popular.
- gnaffle 14y agoThis is correct. Norway exports power in wet seasons, and imports it in dry seasons. But if there is less rain and dam fill-up than expected, they will throttle down on production to save the water in order to sell it at a higher price later on.
- riffraff 14y agoAFAIR it's done in italy too (~1/5 of the national power is hydroelectric) and I am reasonably sure all the big plants work with dams/reservoirs, e.g. http://en.wikipedia.org/wiki/Entracque_Power_Plant http://en.wikipedia.org/wiki/Entracque_Power_Plant
- mpyne 14y agoWell it needs a lot of water (which can be problematic for the areas which solar is most competitive in) and a lot of unused area. It's a very reasonable solution when you meet those constraints though.
