Zach Dell - Powering the Future - [Invest Like the Best, EP.434]

In plain words

Zach Dell says the US grid is old and electricity demand will surge from 2% annual growth to 10% due to EVs, AI data centers, and factories. But building new power plants takes 5-10 years to get approved. His company Base Power installs home batteries that work as a distributed network, avoiding the approval queue. He is optimistic about this model. Key names: Sunrun (a benchmark for home solar and battery securitization), Tesla (argued battery minerals are abundant).

Zach Dell - Powering the Future - [Invest Like the Best, EP.434]

Quick Overview

Zach Dell is the co-founder and CEO of Base Power Company. This episode explores the structural challenges of the century-old U.S. power grid as it faces surging demand from AI, electric vehicles, and industrial electrification, as well as how Base bypasses the approval bottlenecks of traditional large-scale projects through a distributed network of home batteries. Zach Dell argues: "The growth rate of electricity demand will jump from 2% CAGR over the past 50 years to 10% — this may be consensus, but the absolute magnitude means we must redesign the entire grid access approach."


Theme 1: The Structural Dilemma of the Power Grid — A Century-Old Machine, Demand Growth Rate Quintuples

Zach Dell argues that the U.S. power grid is "the most complex machine ever built by humans," but it is completely unable to meet modern demand.

  • Physical Structure: The U.S. grid consists of three major regions (Eastern Interconnection, Western Interconnection, and ERCOT/Texas), with three layers: generation, transmission, and distribution. Transmission lines span hundreds of thousands of miles, distribution lines millions of miles — "All the wires connected together could go to the moon and back several times."
  • Historical Context: In 1900, less than 5% of households had electricity. The New Deal drove the construction of TVA, Hoover Dam, etc. Massive expansion occurred from the 1950s to 1990s, but 40% of grid infrastructure was built before the 1970s and is severely aged.
  • Demand Growth Rate Fracture: Over the past 50 years, electricity demand CAGR has been about 2%. Zach predicts: "In the next 5-10 years, this figure will jump from 2% to 10%." Key drivers: electric vehicles (only 7% of new car sales in the U.S. are electric, 25-30% in Europe, higher in China), AI computing infrastructure, and industrial electrification.
  • Supply Bottlenecks: The generation capacity in the interconnection queue is twice the existing grid capacity, but approval cycles take 5-10 years. Reasons: supply chain bottlenecks (transformer shortages), regulatory political wrangling, and developers "land banking" — submitting multiple applications and waiting for the one that gets approved fastest. Ultimately, only about 20-25% of projects are actually built.

Zach Dell points out: "What we need is not more approvals, but a deployment method that can bypass this system."


Theme 2: Base's Distributed Battery Architecture – Cutting Large Battery Farms into Pieces and Installing Them at Every Household

Zach Dell's core judgment: 99% of grid energy storage is large centralized battery farms, but this model is constrained by two fundamental bottlenecks – grid connection waiting and transmission congestion. Base's distributed architecture precisely bypasses them.

  • Business Model: Users in Texas's deregulated area choose Base as their electricity provider, pay a $500 down payment + $16/month, and Base installs a battery at the user's home. When the grid is normal, the battery is used as a grid resource (charging/discharging arbitrage); when the grid is down, the battery provides backup power for the household. Users save 10-20% on monthly electricity bills.
  • Mechanism Breakdown: Base is essentially a 'distributed battery farm cut into thousands of pieces and deployed behind household meters'. Charging timing: 00:00-04:00 (low electricity prices); discharging timing: summer afternoons 5-8 PM, winter morning peaks (high electricity prices). Additionally, it participates in ERCOT's ancillary services market (voltage and frequency regulation).
  • Comparison with Centralized Storage:
Dimension Centralized Battery Farm Base Distributed Architecture
Grid connection period 5-10 years Bypasses grid connection queue (connected at the end of existing grid)
Transmission congestion Severe (requires site selection at distribution grid nodes) None (co-located with load, directly connected to distribution grid)
Unit cost ($/kWh) Higher Lower (continuously compressed through vertical integration)
Revenue sources Only energy arbitrage + ancillary services Energy arbitrage + retail electricity margin + monthly service fee
Return rate Depends on arbitrage returns Triple revenue stacking, target IRR significantly higher
  • Competitive Landscape: In the energy arbitrage market, Base is a 'price taker' – ERCOT's day-ahead and real-time markets are liquid 'electricity exchanges'. On the retail side, Base does not pursue high margins (traditional retailers 20-30% gross margin, Base is satisfied with 10-15%), core profit comes from battery asset operations.

Theme 3: Unit Economics – Ten-Year Asset, Four-Year Payback, Vertical Integration as the Core Variable

Zach Dell detailed the unit economics of Base's battery, with the core judgment: "In a commoditized industry, your North Star must be cost advantage. Vertical integration is Base's weapon to build a compound cost advantage."

  • Current Generation (Gen 1):
  • Battery landed cost (including hardware, installation, customer acquisition): approximately $10,000
  • Customer down payment: $500
  • Federal ITC tax credit (IRA Act, 30%, 40% in some regions): approximately $3,000
  • Net cost (unlevered): approximately $6,500
  • Revenue sources:
  • Retail electricity margin: ~$200/year (customer average monthly electricity bill $150, gross margin 10-15%)
  • Monthly service fee: ~$200/year ($16/month)
  • Energy arbitrage income: ~$1,200/year (assuming 30kWh battery × $40/kWh arbitrage gain)
  • Annualized total gross margin: ~$1,600
  • Unlevered payback period: approximately 4 years
  • Asset life: 10-15 years
  • Next Generation (Gen 2 → Gen 3) Cost Reduction Path:
  • Gen 2 (more in-house design + manufacturing): landed cost reduced to $8,000, payback period approximately 3 years
  • Gen 3 (self-built factory, fully in-house production): landed cost reduced to $6,000, payback period approximately 2-2.5 years
  • After introducing leverage (LTV 50%), levered IRR can reach 20-30%
  • Risk – Volatility in Arbitrage Income:
  • 2023: Extreme weather, arbitrage gains as high as $100/kWh
  • 2024: Mild weather, arbitrage gains only $20/kWh (down 80%)
  • Zach Dell acknowledged: "Commodity markets inherently have boom-bust cycles. But the 'intrinsic value' of a battery goes beyond arbitrage – it is essentially a 'wire' for shifting energy across time and space. In the future, more revenue will come from utility payments for voltage control, frequency response, capex deferral, etc. These are more stable revenue streams."

Theme 4: The Dual-Track Strategy of Capital Markets — From "Project Development" to "Cash Flow Securitization"

Zach Dell believes that Base's success requires not only physical innovation but also capital structure innovation. "On one side this business is about batteries, and on the other side it's about the yield curve."

  • Current stage: Primarily equity financing, supplemented by venture debt — lenders focus on cash reserves and the ability to raise further capital.
  • Future path: Transitioning to the securitization market — a market with large scale, strong liquidity, and low cost of capital. Sunrun is the benchmark for residential solar securitization.
  • Tax credit handling: Base itself has no substantial taxable income and cannot directly use the ITC. It needs to sell the credits to large institutions with tax burdens through tax credit transfers or tax equity partnership flip structures.
  • Cash flow structure: In the annualized $1,600 gross profit —
  • $1,200 (energy arbitrage) = entirely "commercial" risk (no contract)
  • $200 (retail margin) + $200 (service fee) = closer to "contractual" cash flow (customers sign long-term agreements)
  • If part of the arbitrage gains can be converted into long-term contracts, LTV could rise from 30-50% to 70-80%, significantly reducing the cost of capital.

Judgments Worth Remembering

1. Zach Dell judges that "electricity demand growth will jump from 2% to 10% CAGR" — supported by three simultaneous drivers: electric vehicles (only 7% penetration in the US, 25-30% in Europe), AI computing data centers, and industrial electrification, with absolute incremental demand far exceeding any historical period.

2. Zach Dell argues that "the fundamental bottleneck for centralized storage is not the battery itself, but grid interconnection" — supported by a 5-10 year waiting period in the interconnection queue and only 20-25% of projects actually being built; distributed architecture naturally bypasses these two constraints.

3. Zach Dell's analogy of "battery as a time-space wire" — supported by: "Wires move energy across space; batteries move energy across time." This positioning means the value of batteries is not limited to arbitrage but is an organic component of grid infrastructure.

4. Zach Dell's framework of "cost advantage achieved through vertical integration" — supported by: full control from battery design, manufacturing, installation, ownership, operation, trading, to retail, with the goal of reducing installed cost from $10,000 to $6,000 (Gen 3) and payback period from 4 years to 2-2.5 years.

5. Zach Dell judges that "mineral constraints are not a barrier to battery capacity" — supported by citing Tesla's Master Plan 3, arguing that lithium, iron, manganese, and cobalt are abundant in the earth's crust; the issue lies in mining economics and permitting, not resource scarcity.

6. Zach Dell proposes that "the boom-bust cycle of batteries is normal in commodity markets, but distributed batteries have more stable new revenue sources" — supported by: arbitrage fell from $100/kWh in 2023 to $20/kWh in 2024 (an 80% decline), but future utility partnerships (voltage control, frequency response, capex deferral) can provide more stable cash flows.

7. Zach Dell's methodology of "speed is a strategic weapon" — supported by: "From installing 10 batteries to 100 to 1,000, every time you cross an order of magnitude, you expose yourself to new problems, and it is those new problems that are truly worth solving." Current deployment speed is 20 batteries/day, target is 50/day.

8. Zach Dell's framework on "the capital market is another yield curve" — supported by: the business is essentially a cash flow matching project—tax credits, securitization, and project finance are combined by stage, with the ultimate goal of entering the large-scale securitization market like Sunrun to minimize the cost of capital.
