Base Power owns the home battery and sells you electricity

Recorded 6 September 2026 · 76 min

Base Power's edge is a business model rivals cannot copy without wrecking their own: it does not sell home batteries, it owns them and sells the electricity. A $20,000 battery bought outright sits idle for the 99% of the time the grid is up. Owned by Base, the same box trades in the wholesale market, and the profit funds a lower bill.

Zach Dell, who founded Base Power after finance roles that included Blackstone and Thrive, talks with David Senra of Founders. They cover why a grid that grew at the rate of inflation for 50 years now faces roughly 10% annual demand growth, and why regulated utilities paid on capex have no reason to innovate.

The tension is ambition against discipline. The mission is a 50-year, never-finished push for energy abundance across making, moving, storing and selling power. The daily practice is narrow: one constraint, three north stars, and a physical turtle on the desk of whoever is blocking the critical path.

  1. Too small, not broken — ▶ 1:31

    The grid is not broken; it is "too small." Utilities are rate regulated and paid on capex rather than R&D, so their R&D spend as a share of revenue is "as low as any industry you'll ever find." They behave as project-management and capex organizations, not engineering ones. Their only question is how fast they can build and earn a return on it. Base Power positions itself as the opposite: an R&D-driven, engineering-led energy technology company building technology to scale how much electricity the system can consume and deliver.

  2. Demand finally inflects — ▶ 2:57

    Over 50 years, US electricity demand grew at roughly the rate of inflation. EVs, heat pumps and heavy-industry electrification were meant to change that but have played out more slowly than expected. Demand compounded at about 2% a year over the last 20 years, and Dell expects something on the order of 10%, a 5x acceleration on a base "as large as energy is." AI infrastructure is the accelerant. He admits he does not know the exact size of the AI load, only the direction.

  3. Mission, vision, strategy — ▶ 4:05

    The mission is human prosperity through energy abundance, anchored in the correlation between energy consumption per capita and GDP per capita. The vision: the last five decades were defined by coal and then natural gas as the marginal megawatt, and the next five will be defined by solar, batteries and software. The strategy is a compounding cost advantage through vertical integration and technology. Electricity is a commodity, and the best commodity is the cheapest and most reliable one, so the whole business is oriented around cost.

  4. Batteries move energy through time — ▶ 6:23

    The grid is built for peak, so it is oversized and runs at low utilization, which makes delivered power expensive. Batteries charge when demand is low and discharge when it is high, flattening the demand curve and raising the capacity factor. In Texas, midday solar drives wholesale prices very low and some solar is curtailed. After sunset, AC load spikes prices and Base discharges. "We didn't create new electricity, but we timeshifted it." Today's product makes no new electricity; it makes the existing system cheaper.

  5. Why distributed beats utility-scale — ▶ 14:26

    At Blackstone, Dell saw that utility-scale batteries, the shipping containers in a farm field, were a good asset class. Apollo, KKR, Oak Tree, Ares and Brookfield all own such platforms. But they are constrained by interconnection capacity and transmission congestion. Load pockets like downtown Austin, Dallas and Houston are not where a container can go. Putting batteries on homes puts them where the interconnection already exists and where the load is, sidestepping both limits. The host admits he had not understood this before.

  6. Counterposition, not a better product — ▶ 15:38

    Every residential storage company Dell studied sells a $20,000 battery or generator outright at high gross margin. His view: if you take on an incumbent, do not sell a better battery 10% cheaper, because "Your margin is my opportunity." Rivals copy the product and cut price. Instead, Base says "I don't sell batteries. I sell electricity," and the homeowner pays 1/20th or even 1/40th of the outright price. To compete, an incumbent must change its model, which Wall Street, used to a decade of the old margins, "doesn't like very much."

  7. Ownership delivers the outcome — ▶ 21:00

    Customers want a lower bill and no outages. A homeowner who owns a battery is not a wholesale market participant, has no scheduling entity or hedging team, and so cannot use it for the 99% of the time the grid is up. Base owns it, runs it as a wholesale power asset, and shares the value as a lower price: "a box on your house that is going to generate money." Ownership is the way to deliver the best product, not greed. The host compares it to Howard Hughes Sr. leasing drill bits for recurring revenue.

  8. Texas 80/20 and co-ops — ▶ 22:34

    Electricity is one of the few US industries never fully deregulated. Enron's manipulation stalled California, and Texas carried the torch. Texas is now 80% deregulated and 20% regulated: municipal utilities like Austin Energy, CPS and Georgetown, plus co-ops like Co-Serve. In deregulated territory Base competes with retailers like Vistra, Constellation and NRG. In regulated territory it is a vendor. Co-Serve is building a 100 MW, soon larger, fleet of home batteries it charges cheaply, discharges at high prices and shares the spread with members.

  9. Outsourced R&D, megawatts as a service — ▶ 26:19

    Regulated utilities earn a return of typically 9% unlevered on approved capex, so their only incentive is a bigger rate base. Base pitches itself as their "outsourced R&D engine," scaling infrastructure without raising rates. The deal is 10-year contracts for fleets of 100, 500 or 1,000 MW, "megawatts as a service," and the long term gives Base cash-flow certainty to finance the build. Dell will not say the whole grid should be regulated or deregulated; he says the poles and wires make sense as regulated and the answer is geographic.

  10. SpaceX playbook, one location — ▶ 34:08

    Justin, Jared, Cole Jones and Antonio Gracias come from SpaceX, and Dell credits Elon Musk with training a cohort of hardware engineers. Engineering and Factory 1 are a 2-minute walk apart, so an engineer can design a part, watch it assembled, find the failure mode and fix it, "a massive accelerant." Elon's company took a building Base nearly leased, so Base is building a campus near the airport with manufacturing and engineering together. No private offices: "Private offices are lame." Some practices are SpaceX-derived, others grew organically.

  11. Write to think — ▶ 39:52

    Base began with a 10-page memo on why it exists and how it wins. Dell has written a monthly update for 3.5 years without missing one, and uses it for recruiting and fundraising. He keeps a red notebook for working in the business and a black one for working on it. Each night, after his wife goes to bed, he spends 30-60 minutes with phone and computer in another room, staring at a page until ideas arrive. Moving to a computer made "all the good ideas go away."

  12. North stars, turtles, TVs — ▶ 44:57

    Three north stars sit on a poster in the office and the factory: the fastest-growing distributed battery fleet, the lowest landed cost per kWh (hardware, installation, customer acquisition, overhead, operations), and financial sustainability. A physical turtle sits on the desk of whoever is on critical path until it is resolved, with a daily "hot potato" squad and a weekly company email. Green-and-red metric TVs hang over every team. Dell also gives a quarterly "engine of success" lecture to the 500-person company on how it wins.

  13. What's your constraint? — ▶ 56:32

    Board member Antonio Gracias asked Dell the same question for the first year or two of conversations: "What's the constraint?" It is uncomfortable because the natural pull is to discuss every opportunity, which Dell calls "a cope." He and co-founder Justin hold Sunday one-on-ones and never discuss what is going well, even though the last three years have gone "unreasonably well." The metrics, dashboards, hot potatoes and turtles all exist to expose and resolve what constrains the path to the mission.

  14. Base Core and the supplier wall — ▶ 1:06:46

    The Base Core is a custom battery that comes out of three years of operating tens of thousands of home batteries. It is designed in-house, built across the street, with lower bill of materials, faster install, cleaner switchover and more power and duration. Base is sold out through November in August because its supplier is tapped out. Three years ago no supplier would invest hundreds of millions in capex on a startup's promise: "Get out of here, kid." Building it itself lets Base keep the OEM margin and control its own execution.

  15. Year three versus year 30 — ▶ 1:09:48

    Dell could mine lithium and make cells, but returns to integration diminish, and today Base does final assembly, test and pack while suppliers handle fabrication. Deeper integration is a "year 30" question. Energy is make, move, store and sell. Base started with store and sell for scale and return on capital, and wants to work across all four. The stack is also pointed at AI, bringing power to compute and compute to power. This is his last company, the mission never ends, and it is not for sale.

The open question. The arbitrage rests on the Texas price shape Dell describes: cheap midday solar, expensive evenings. The conversation never tests what happens to that spread as Base's fleet grows from tens of thousands of batteries toward hundreds of thousands and itself flattens the curve it feeds on. No unit economics are given either, though financial sustainability is one of the three north stars still to be hit this year. The AI plan, bringing power to compute and compute to power, gets a single vague paragraph. Watch for margin per battery and for what the first AI-facing deployment actually looks like.
