These batteries will work great to capture the renewable energy 24/7 to be utilized at peak times of the day. Renewables don't always produce at the optimum time and this resolves that issue.

Very cost effective compared to a full-on new coal fired plant just to run four hours a day during peak demand.

IMO as these systems are implemented and expanded they will eventually take over the bulk of the grid supply at a lower cost.
