Now we come to hydropower.

Here it is interesting to distinguish between two types.

The river runoff type uses the water at the time it runs down the river and normally has no or just very little storage capacity.

The storage type sometimes can store the water which runs into its reservoir for many months (see following table). So this kind of power plant decouples runoff and electricity production and thus gives the degrees of freedom necessary to be used as back up to balance the variation of other production facilities and of the demand.
