Base Power raises another $1B to save the grid using backyard batteries
Energy startup Base Power has raised $1 billion in Series D funding to expand its network of residential battery storage systems. The company aims to stabilize the grid by installing home batteries that can be tapped during peak demand periods.
Why it matters
As AI data centers and electrification strain the power grid, decentralized storage solutions offer a scalable alternative to traditional infrastructure upgrades.
Where most energy storage companies look for big tracts of land near large connections to the grid, Base Power is betting that it can beat them all by putting batteries in people’s backyards instead.
It appears to be paying off, with Base Power installing more than 500 megawatt-hours of storage over the past few years. The startup announced today that it has raised another $1 billion less than a year after its last billion-dollar round.
The Series D values the company at a $13 billion post-money valuation. Base Power is installing about 100 batteries per day, according to The Wall Street Journal report, and it hopes to double that by the end of the year. That works out to about 8 megawatt-hours of storage installed per day.
