Base Power
Subscription home batteries that stabilize the grid and back up homes
About Base Power
Base Power Company is an Austin energy-storage startup that deploys subscription home batteries in customers’ backyards to provide backup power and grid services, rather than building large standalone storage sites. Co-founded by CEO Zach Dell, Base installs batteries it owns, charges a modest install fee plus monthly and per-kWh rates, and sells stored electricity back to the grid at peak demand while giving homeowners outage backup; it operates in Texas and Illinois and has installed more than 500 MWh of storage, with about 100 batteries per day. In August 2026 Base launched Base Core, a U.S.-made home battery built at its Austin factory that stores 39.2 kWh. The same month it raised a $1 billion Series D at a $13 billion post-money valuation co-led by Ribbit Capital, Addition, Valor Equity Partners and JPMorganChase’s Strategic Investment Group, with Altimeter, D1, Sands, Coatue, a16z, Lightspeed, CapitalG and others, less than a year after a prior billion-dollar round.
