Mr. Bobby Smith:

The short duration storage operational today comprises roughly 750 MW. It is assumed that will still be in place by 2030, providing those short-term system instability services. On top of that, 2 GW will be built. I referred to 2 GW of varying durations of storage. A scenario was considered involving 2 GW of four-hour storage, 2 GW of 16- to 20-hour storage and 2 GW of 100-hour storage. They were compared and all had net consumer benefits, but the 100-hour storage delivered the most consumer benefit.
