Batteries would help. It will take a lot of them. At least 300,000 Tesla Powerwall battery packs would be required to load balance that variation in wind. That's about a billion dollars, which is not unreasonable. The price would of course go down for quantity, and putting the individual cells into larger units. Let's wave our hands and say 900M -> 500M.

So half "a billion dollars" every 13.5 years, ~100K/day.
