Short-term storage that lasts just a few minutes will ensure a solar plant operates smoothly during output fluctuations due to passing clouds, while longer-term storage can help provide supply over days or weeks when solar energy production is low or during a major weather event, for example.
The storage system cost and size improves when designed accordingly. For instance, use a high efficiency system (e.g. battery) for that first 'day' of storage (48 billion kWh) which might see a charge/discharge cycle every day to handle backing up solar at night.
Coupling solar energy and storage technologies is one such case. The reason: Solar energy is not always produced at the time energy is needed most. Peak power usage often occurs on summer afternoons and evenings, when solar energy generation is falling.
The amount of energy a PSH project can store depends on the size and height difference of the two reservoirs it is made up of, while the amount of electricity it can produce at once depends on the size of the turbines.
That''s where pumped-hydro storage is so important, because it can store energy at the grid scale. For pumped-hydro storage, you need two reservoirs with a significant height difference;
