Where most energy storage companies look for vast plots near power grids, Base Power is betting on a more personal approach—backyard batteries. The startup has just raised another $1 billion, valuing it at $13 billion post-money, and plans to install about 8 megawatt-hours of storage per day by doubling its current rate. Its new Base Core device can store 39.2 kilowatt-hours of electricity, significantly more than competitors, making it a standout in the market.

With soaring electricity demand due to widespread electrification and AI data center construction, Base Power’s strategy is particularly timely. By offering batteries on a subscription basis rather than upfront costs, they’re making energy storage accessible. In regulated markets, their approach helps ease grid strain, while in deregulated areas, homeowners benefit from backup power during blackouts.

Base Power operates primarily in Texas and Illinois, where parts of PJM’s territory experience significant strain on the grid, creating a ripe environment for their innovative solution. The round was led by notable investors including Ribbit, Addition, and JPMorganChase, signaling investor confidence in Base Power's vision.

The company was founded by Zach Dell, CEO, with his father Michael Dell, former CEO of Dell Technologies, notably not participating this time around. As Base Power continues to expand its footprint, it’s clear that the future of energy storage might just be right outside your window.
