Nope, I talked about incentivizing consumers to shift their demand based on a volatile price. I pointed out that much of this can be accomplished without need of batteries.
For example, have the hot water tank heat up water higher than normal when electricity is cheaper, and lower when electricity is more expensive. Hot water tanks lose heat very slowly, this could result in never needing to heat water during the expensive times.
It's a heluva lot cheaper than having a battery do it.
Second, it's not a single location. Wind may be lower in one location, but strong in another location 50 miles away. The idea that wind goes completely dead all at once across statewide areas is not how wind actually works.
The idea that wind currents are uncorrelated across geographical areas, even on the scale of states, is not how wind actually works.
