Tree-huggers have something new to talk about today. The genius has struck again.
(BTW "Elon" means "tree" in Hebrew) http://www.forbes.com/sites/uciliawang/2014/05/07/teslas-elon-musk-on-creati ng-a-cool-battery-system-with-a-beautiful-cover-for-home-energy-storage/ No one could figure out exactly why Tesla needed a billion dollar battery plant which was 10 times too large for projected production. Answer: they will sell the excess to home owners (or Utilities or Solar installers) for load leveling and for solar storage... not to mention: use the leverage of plant location to get some silly laws off the books in places like Texas. Think about it - extremely large differential electrical rates (highly favorable) exist between late night and midday - in many states, which will pay back such a basic storage system in a much shorter time than would solar, but the two together make sense as well. Even without solar, you charge the batteries at late night for the next day's use. The grid supplier is better off since he can keep the generators turning 24/7. In fact, the big electricity consumer can probably get a load leveling system installed for free - eventually, once the power companies realize how this can save them money. It may eve become a requirement in some states.
