Storage is a key component of the National Grid's approach to dealing with the intermittency of wind.
Although all major forms of storage are expected to increase in capacity towards 2050, the one with the greatest increase during the timescale of the current Five Year Forecast is battery storage.
The National Grid greatly reduced its figures for battery storage from FES 2019 to FES 2020, but the implementation of battery storage continues to lag behind the revised figures.
As you can see from the chart, the storage capacity of battery storage is currently well below the National Grid's figures.
For information about the capacity of battery storage to the end of 2020 see this article.
At present pumped hydro is the most signficant form of storage in Great Britain, and this will continue to be the case for some years. However, its capacity is not expected to increase over the next few years.
Note that storage here excludes Vehicle-to-Grid storage and Hydrogen storage. These will not make a signficiant contribution during the next 5 years according to National Grid figuress.
