Zach Dell

In 2018 a summer analyst at Blackstone was handed the utility-scale battery file and reached a conclusion the industry was not yet willing to underwrite. "One thing became really clear to me," Zach Dell said later. "The marginal cost of solar plus storage was going to fall below the marginal cost of coal and natural gas."¹ He waited five years, and then built a company whose entire structure depends on owning as little of the scarce thing as possible.

Dell is the co-founder and chief executive of Base Power, an Austin company that installs oversized batteries on people's houses and sells them electricity. The Wall Street Journal profiled him at 29 as the Dell scion trying to shore up the Texas grid one home at a time.² He is the son of Michael Dell, whose own file sits one plate over in this archive.

The tension

Base's advantage is that it does not own the bottleneck. It owns no land, no power plant, no grid interconnection, and no transmission. Every scarce input is supplied, without charge, by the homeowner who already has them. That is a genuinely elegant structure and also a fragile one, because the whole thing rests on a regulatory accident: the customer has to be allowed to choose a power provider at all, and in most of the United States they are not.

Getting started

After Blackstone, Dell worked at Thrive Capital. Thrive had invested in the defense manufacturer Anduril, and on a factory tour there he met Justin Lopas, who ran Anduril's manufacturing and had built rockets at SpaceX before that. The two became friends, kept talking, and settled on electricity. Dell's framing of the opportunity has not changed since: "What SpaceX did to aerospace; what Anduril did to defense; no one has done to the energy grid."¹

They started from a deliberately naive question, in Lopas's words, of why energy is not cheaper. The answer they arrived at was not a technology gap. Batteries were already falling in price on a durable learning curve. The obstacles were procedural and institutional: the interconnection queue, where roughly 2,600 gigawatts of generation and storage sat waiting against a grid with 1,279 gigawatts installed, and where a project that took under two years to connect in 2008 now takes nearly five; and transmission congestion, which lands the power in the wrong place even after the wait is over.¹

Their answer was to chop the battery farm into thousands of pieces and put them on houses. Houses are already interconnected, so there is no queue. There is no land to buy and no construction to manage. And a house can draw from its own battery without touching the grid at all, so congested wires stop mattering.

What he built

Base does not sell hardware, and Dell is precise about the distinction. "We don't sell batteries," he said. "We sell affordable, reliable power."¹ A homeowner pays a setup fee in the hundreds plus, in some areas, roughly $19 a month, for a battery that would cost well over ten thousand dollars outright. In markets where customers may choose their provider, they get a fixed rate for three years, typically 10 to 20 percent below their bill. In exchange, Base trades the battery against the grid: charge overnight, discharge into the evening peak. Most of the unit revenue is that spread, which is why both parties want a bigger battery, exactly inverting the incentive of a company selling batteries at a sticker price.

The scale arrived fast. Installs went from one a day in June 2024 to a hundred a day in June 2026.³ Utility partnerships went from under five percent of volume to more than half in a year, including 40 megawatts contracted by Austin Energy and 100 by the cooperative CoServ.¹ In August 2026 Dell announced the Base Core, a 39.2 kilowatt-hour battery giving an average home about 36 hours of backup, alongside a $1 billion Series D at a $13 billion valuation.³

How he operates

The operating thesis is a single sentence he repeats without variation, and which the company has taken to calling Base Pace: technology, plus vertical integration, plus relentless execution, leads to a compounding cost advantage.³ The evidence he offers for it is not a margin chart but a product comparison. Base's first battery was 25 kilowatt-hours. Three years later the 39.2 kilowatt-hour Core shipped at the same price, installed in under an hour, built at a converted newspaper factory in downtown Austin that was standing and producing in eight months.¹

Underneath sits a commodity view of the product that he states more bluntly than his investors do. "There are no sexy electrons."¹ The best electron is the cheapest one, so the company is designed around cost rather than around differentiation, which is the discipline that makes Wright's Law a business plan instead of a chart.

His diagnosis of the incumbent is the sharpest thing he says. Lopas supplied the analogy from his Anduril years, that regulated utilities squint into something like the defense primes. Dell supplied the compression: "What you have is an incentive to build but not innovate."¹ Under rate-basing, a utility earns a guaranteed return on what it spends, so a technology that does more with less is a threat to earnings rather than an opportunity. It is a claim about incentives, not competence, and it predicts precisely where the incumbent will decline to follow.

Where things stand

Base operates across Texas and has expanded into Illinois, with a fleet over 500 megawatt-hours deploying roughly 40 megawatts a month.¹ Dell's stated ambition is larger than storage: "Electricity is the largest and most essential industry in the world, and it does not have a defining technology company."³ Base intends to be it, with solar named as the next product to run through the same flywheel.

The archive files him under examination rather than on a plate. The pattern is legible enough from outside, and the second-generation question is obvious enough to ask, but this catalog classifies only what a founder or a close observer has articulated about that founder, and on the record so far Dell describes a thesis and a cost structure rather than himself. The reader who wants the family pattern stated should read the two files side by side and draw their own line.

Key facts

• Concluded at Blackstone in 2018 that solar plus storage would fall below the marginal cost of coal and gas, then spent five years before acting on it.
• Met co-founder Justin Lopas, formerly of SpaceX and head of manufacturing at Anduril, on an Anduril factory tour while working at Thrive Capital.
• Founded Base Power in 2023 in Austin; the company sells electricity, not batteries, and earns most of its unit revenue arbitraging home batteries against the grid.
• Scaled installs from one a day in June 2024 to a hundred a day in June 2026, and utility partnerships from under 5 percent of volume to more than half in a single year.
• Raised a $1 billion Series C in October 2025 and a $1 billion Series D in August 2026 at a $13 billion valuation, having passed $1.3 billion raised by February 2026.
• Manufactures at Base Factory 1, a converted newspaper factory in downtown Austin brought online in eight months.
