Base Power raises $1 billion Series D at $13 billion valuation for home batteries

Base Power said it raised $1 billion in a Series D funding round at a $13B valuation to mass-produce Base Core, a home battery the company positions for outage backup and selling capacity back to utilities. VentureBurn reported Base has 500+ MWh deployed and 200+ MW in utility deals, framing residential batteries as a fast way to add power as AI data centers and EVs raise electricity demand. The funding is tied to a product launch of Base Core as Base seeks to put batteries in U.S. homes. The write-up notes that new gas plants take years while utilities face rising load.
