More From Elon Musk on Solar Batteries and Utilities

We're always happy to hear from Elon Musk.  Here's what he recently said to the AFR about solar batteries and utilities.  Here's an excerpt:

Elon Musk, chief executive officer of Tesla Motors, has told electric utility owners they shouldn't fear that his battery systems will put them out of business - instead, they should buy them.
Most customers in the US will use the Powerwall home system as a backup in the event of a failure, not as a primary source of electricity replacing utility sales, Musk said Monday at a gathering of utility executives in New Orleans. Plus, electric cars like the Tesla Model S will help triple demand for power, and less than a third of that will be served by distributed generation like the battery storage system and solar panels Musk has backed.
Musk unveiled a suite of batteries in April that he said would "fundamentally change the way the world uses energy." The equipment allows businesses and homeowners to store power, reducing the need to rely on utility grids for electricity. Musk said the media has been confused about the role of the home battery pack, which wouldn't be economic as a main supply source. He sees 80 to 90 per cent of sales being in the larger Powerpack system, which could help utilities store power to reduce the need for expensive facilities that only run during times of peak demand.
