About a month ago, we were telling you about a new battery for houses Tesla was working on, that might revolutionize home energy and bring forth massive change in renewable energy – now, the official announcement is out. Homeowners will be able to get the Powerwall battery, in 7 or 10 kilowatt modules, which will cost $3000 and $3500 respectively.

When dealing with electric cars and even renewable energy, storing energy is one of the major problems – you get a lot of wind and solar energy during some periods, and not that much during other periods. If you could somehow store that energy efficiently, then suddenly renewables become much more viable. Enter the stage Tesla.

“It’s really great. I’m really excited about it,” Musk said in February. Mass production could be only six months away, he added. He also stated that the battery will feature a chique design which will blend into any home design.
Tesla addressed homeowners directly, who can start integrating renewables much more effectively, but the new battery also comes with an industrial option – the Powerpack, sold in 100 kilowatt-hour modules at $25,000 each is remarkable too. But perhaps even more importantly, the biggest impact on energy storage might come at the electricity grid as a whole. A late 2014 study by the Brattle Group, prepared for mega-Texas utility Oncor, found that energy storage “appears to be on the verge of becoming quite economically attractive” and that the benefits of deploying storage across Texas would “significantly exceed costs” thanks to improved energy grid reliability. Storage is a game changer.
