In the Future, Your Home May Be Powered by a Tesla Battery
THE BATTERY-POWERED FUTURE
Battery technology has essentially been the same over the past years, albeit with a bunch of improvements that increase battery capacity and prolong battery life. Lithium ion batteries remain the popular choice, and they’re found in all of today’s battery-powered mobile devices and in many electric cars. Soon, these batteries might also be powering your houses, thanks to the likes of Tesla and other startups that now sell these home batteries to utility providers.
According to a report by The Wall Street Journal, homes located in New York, California, Massachusetts, Hawaii, Vermont, Arizona, and in other states are working on new ways to make their electric grids battery-powered, an infrastructural switch which Ravi Manghani of GTM Research says is a “powerful need.” Without home batteries, the ability of utility companies to deliver power is in danger.
Utilities often have difficulty allocating excess power, particularly those on interstate markets where at certain times the price of electricity tends to dip into the negative. Usually, utilities resort to dumping excess electricity or paying others to take it. With the rise of solar power, the same issue happens. Energy generated by solar panels depend on certain conditions and, more often, generation doesn’t match the needs of homes.
In California and Arizona, the Journal reports, there’s lost of solar electricity during the day at cool times of the year and too little at night, when usage spikes. “This is not a long-term theoretical issue that might happen—this is now,” Marc Romito, Arizona Public Service director of customer technology, told the Journal. Home batteries are sorely needed.
IN A TIME OF NEED
There’s wisdom in keeping spare batteries at home, or in this case, keeping your home plugged into one. Particularly during times of disasters, home batteries can be really useful. When the grid is down, home batteries coupled with solar panels can provide much needed electricity, as was the case in the aftermath of Hurricane Irma, where customers of Tesla and German battery-maker Sonen were able to keep their houses powered. Tesla has also, in fact, started shipping batteries to Puerto Rico, which has been largely without power since Hurricane Maria.
IN BRIEF
A shift in how electricity is generated and when it’s used is creating a massive need for home batteries. These home energy storage devices, like Tesla’s Powerwall, are particularly useful during natural disasters.

It’s this self-sustaining energy ecosystem that Tesla’s been working on thanks to their Powerwall and Powerpack batteries. Both work as electricity storage units, with the former designed for homes, while the latter is meant for utilities. Instead of relying on the grid, the home batteries like the Powerwall allow households to source out electricity, so to speak, following what some have called a “grid defection.” It’s enough to even power a small island.
