Home energy battery startup Base<\/a> has raised $1 billion in a Series D funding round, propelling its valuation to $13 billion less than a year after being valued at $4 billion.<\/p>\n

The financing was co-led by Ribbit Capital, Addition, Valor Equity Partners, and JPMorgan Chase\u2019s Strategic Investment Group. Existing investors including Thrive Capital, a16z, Lightspeed, Trust Ventures, and CapitalG also participated in the round, reinvesting in the Austin, Texas<\/a>-based enterprise founded in 2023 by Zach Dell.<\/p>\n

Instead of relying on hardware retail markups standard in residential battery sales, Base operates as an infrastructure utility. The company generates revenue by taking equity in retail power markets and trading energy on wholesale grids\u2014charging installed battery units during low-cost off-peak hours and supplying stored energy back into regional grids when wholesale electricity prices peak.<\/p>\n

\u201cOur business model, which is very unique, is that we\u2019re really an infrastructure company,\u201d Dell said. \u201cWe own and operate the assets in the wholesale power markets. That\u2019s really where we make our money, not by trying to sell the consumer something at a really high-margin upfront cost.\u201d<\/p>\n

To support its scaling velocity, Base opened Base Factory 1 in Austin earlier this year to manufacture proprietary 39.2 kilowatt-hour battery storage units designed for high-capacity grid integration, replacing third-party systems. Construction is underway on a significantly larger second facility scheduled for completion in 2027.<\/p>\n

\u201cThis battery is designed to be a grid resource,\u201d Dell said. \u201cIt\u2019s bigger, it installs faster, it switches over cleaner, it\u2019s more powerful, it has more duration.\u201d<\/p>\n

Base has expanded its deployment pace from single daily installations to over 100 systems per day, building a customer base exceeding 30,000 homes. Consumers access the power storage systems via an installation fee capped at $695 alongside a $19 monthly membership fee, avoiding traditional upfront equipment purchases that often exceed $15,000 for home generators or alternative storage solutions. Customers retain backup power during localized outages lasting up to two to three days.<\/p>\n

\u201cWe\u2019re charging the batteries when prices on the grid are low, and we\u2019re discharging the batteries with demand when prices on the grid or high,\u201d Dell said.<\/p>\n

Having initially targeted the Texas electricity market, Base recently expanded into Illinois<\/a>, offering promotional installation rates of $95 to accelerate adoption in new service areas. \u201cWe\u2019ll likely experiment with pricing based on market signals as we enter different markets,\u201d Dell said.<\/p>\n

The enterprise is positioning itself to capture market share within the $200 billion U.S. residential retail electricity industry, planning further expansion into additional states through deregulated markets and monopoly utility partnerships.<\/p>\n

\u201cWe want to bring Base to every neighborhood in America over time,\u201d Dell said. \u201cThe scale of the opportunity is just massive and, of course, we do have global ambitions. We think markets like the U.K., Germany, Australia, and potentially others are attractive as well.\u201d<\/p>\n

The capital injection arrives as rapidly increasing power demand driven by data center development and artificial intelligence infrastructure puts sustained pressure on electrical grid capacity nationwide.<\/p>\n

\u201cAll the investors are really long-term oriented thinkers, given the size of the opportunity and the time it will take to kind of execute into it,\u201d Dell said. \u201cWe\u2019ve made a lot of progress but, in the grand scheme of things, we\u2019re really just getting started.\u201d<\/p>\n

Base offers residential setups in single or dual-battery configurations. \u201cMost people actually want two, but not everyone has room on the side of their house for two,\u201d Dell said.<\/p>\n

Dell, who turns 30 later this month, operates Base independently of his father, Dell Technologies founder Michael Dell, who serves as a mentor to the enterprise.<\/p>\n
