hydro-generated electricity is great, and if they are pumped using renewable energy when supply is high then in theory they could be used to supply that energy when supply is low.
But thanks for that link. Tâmega energy storage complex is actually looking like it will be a real renewable storage, using two attached wind farms. Just like with solar, when renewable is combined with storage it makes more sense when the renewable plants is located next to the storage and operated by the same company.
It would be really interesting to hear some numbers from that plant, like how much money they gain by storing the wind power and selling it at a later point in time. It would also be very interesting to see the cost per kw/h, even through at this point in time with energy prices being what they are, I will likely not matter too much.
