The CSIRO and ENA says the amount of storage needed beyond that 30 to 50 per cent continues to be minimal until much greater levels of renewable energy are introduced, and then the extent of that back-up is largely dependent on local weather and climate, and their natural renewable energy sources.
With more renewables, there are more chances of excess generation and thus more opportunity to use storage profitably. And likewise, with more storage in place, more renewable capacity makes sense as excess generation is not lost but can be stored and used later.
As of 2016, the installed storage power capacities 4 in Europe, the U.S., and Germany are 52 GW, 24 GW, and 7 GW ( U. S. Department of Energy, 2018). About 95% of this capacity is provided by PHS (50 GW, 23 GW, 6.5 GW U. S. Department of Energy, 2018 ).
The results of five German and European studies are summarized in the appendix (table A2 ). The reported optimal storage energy capacities are large enough to supply 12–32 d of the average load within the considered region, which is about 2–3 times longer than what time series analyses found as the duration of low-wind events.
The analysis indicates that up until 80 per cent wind and solar share, less than five hours of battery storage at average state load is required to support energy balancing working together with the existing dispatchable technologies such as hydro and gas.
Supports the integration of more wind and solar generation: Wind and solar are the cheapest sources of electricity. Energy storage supports the integration of higher and higher shares of renewables, enabling the expansion and incorporation of the most cost-effective sources of electricity generation.
