Cool Stuff – Tesla’s Powerwall Revolutionizes Energy Storage

I was lucky enough to be at Tesla Motors' announcement reception at the Tesla Design Center in Hawthorne, CA a couple of weeks ago, at which the car (and now energy) company announced its Powerwall, a home battery product that folks can use to store energy from their solar panels or to protect their homes against blackouts.

One of my favorite parts of the day was Tesla’s CEO, Elon Musk, who didn’t beat around the bush when discussing his competition: “The issue with existing batteries is that they suck.” And…“They’re expensive, they’re unreliable…stinky.” The Verge says Elon gave the best keynote by a CEO - ever! I thought it was pretty good, too, and it was really fun to be present with so many Tesla enthusiasts.

In a nutshell, Tesla’s Powerwall allows you to store solar power for use over night or when it is cloudy, providing a capacity of seven kilowatt hours for $3,000 or 10 kilowatt hours for $3,500 (not including the cost of installation and a power inverter), and nine of them can be used together for an expanded scope of energy savings. This battery wall is designed to allow you to keep mission critical servers and phone systems on while we wait for the power to come back.

In the long term, this technology will allow public utilities to stop building power plants, because the efficient batteries will let them produce power for the large battery installations at off peak usage times. That will be a huge deal to the utilities, since they will no longer need to size power plants for peak usage.

To cut down on energy waste, California plans to have public utilities store energy by 2024. The Powerwall gives people the opportunity to get that stored energy and prepare for power outages while saving money.

The fact that Tesla was already the biggest provider of battery storage under California’s subsidy program for storage projects is the reason you can trust that this technology will work. Musk is simply streamlining already successful products.

The Verge’s coverage of this new energy source said it best: “Jobs was selling a better smartphone. Musk is selling a better future.”
