## Power Hour

When Tesla debuted its Powerpack 2 energy storage system in 2016, *Business Insider* [heralded it](<https://www.businessinsider.com/tesla-powerpack-2-commercial-battery-facts-features-2016-11>) as "massive." The idea was to standardize a power storage unit that could be deployed en masse to store extra energy from the grid and then dole it out when it was needed.

Now the blog *Electrek* has [obtained a Tesla proposal](<https://electrek.co/2018/12/15/tesla-megapack-debut-giant-energy-storage/>) for a huge Californian energy facility — and details show that the company's upcoming Megapack energy storage system will be twelve times as powerful at the Powerpack 2, a colossal step up for Tesla's energy ambitions.

## Megapack

According to *Electrek*, a Tesla proposal for an energy storage installation the company is providing for utility company PG&E reveals that each Megapack will consist of a 23-foot (7-meter) battery system. The PG&E substation will call for 449 Megapacks, for a total of 1,200 MWh. According to *Eletrek*'s math, that means each Megapack will pack a punch of about 2,673 kWh. The system is scheduled to go online by the end of 2020.

"It’s hard to overstate the size of this project," wrote *Electrek*'s Fred Lambert. "It could be a game changer for California."

*An earlier version of this post misstated the apparent kWh of a Megapack and MWh of the PG&E project. It has been updated.*

I'm responsible for editing, assigning, and scouting at Futurism, as well as occasionally writing for the site. That work involves keeping an eye on a wide range of narratives and issues, but over the past few years I've become increasingly interested in how AI is shaping the future of media, the web, and information itself. My day-to-day often involves collaborating on reporting and commentary projects bylined by my colleagues, but I try to find time to do my own reporting as well; stories I've broken for Futurism have been cited by publications including the New York Times, the Washington Post, the New Yorker, Wired, Ars Technica, New York Magazine, the Columbia Journalism Review, Bloomberg, and more. I grew up in Southern Vermont and attended Vanderbilt University. Prior to Futurism, I contributed to outlets including the Boston Globe, Vice, Wired, Slate, the Atlantic, the Outline, Ars Technica and more, and did stints in farming and food service. I currently live in Brooklyn, New York, and in my free time I enjoy pinball, word games, cycling, running, and music production.
