According to CEO Elon Musk, a new Tesla battery could  be the primary source of power for your home and will also offer large-scale utilities a way of storing energy more efficiently.

And in true Musk fashion we’re not going to have to wait years to see the tech. Apparently, the designs for a home and business battery are already finished and are expected to be showcased to the public “in the next month or two.” If you know anything about Elon Musk, you’d know he’s a man of his word too.

“It’s really great. I’m really excited about it,” he said. We bet you are Mr Musk and we are too!

No details have been released about pricing yet but it’s likely that it will save you a lot of money over your electric bills from the grid. Given the global boom in solar energy, a lot more of your devices could be kept charged up for free in the near future. One of the biggest problems with generating your own energy from renewable sources has been storing it. Solar energy for example is only generated during the day and any excess energy goes back to the grid.

The new Tesla battery will offer a way to store the excess power generated so that you can use it at another time. There has never really been many options to power your home other than to rely on your local utilities provider (or invest in some form of generator). Unless you’re living a frugal life in a small wooden hut or something, solar power hasn’t been able to quite take on the job itself yet. Generating your own power would also mean that you don’t have to deal with frequent outages and the poor customer service o fyour utility provider.

“There may be a ‘tipping point’ that causes customers to seek an off-grid approach,” Morgan Stanley wrote last March. “The more customers move to solar, the remaining utility customer bill will rise, creating even further “headroom” for Tesla’s off-grid approach.”

Tesla is already laying the groundwork to ensure its stationary batteries get as widely distributed as possible.

“A lot of utilities are working in this space, and we’re talking to almost all of them,” said Tesla’s chief technical officer, JB Straubel. “It’s early stage stuff and a lot of these projects are very far out since the procurement cycle for utilities is so long. But this is a business that certainly is gaining an increasing amount of our attention.”
