Power Is the New Bottleneck: The Commoditization of Spacecraft Subsystems

Every era of the space economy has had one binding constraint that gated everything else. For fifty years it was launch: access to orbit was so scarce and expensive that missions were designed around scarcity. Reusable rockets broke that constraint, and the backlog of ambition it released — megaconstellations, commercial stations, orbital data centers — is now colliding with the next one: electrical power. When Beyond Reach Labs CEO Mitchell Fogelson says customers just want an outlet to plug into, he is describing a market in the middle of a phase change.

Why Power Is the Emerging Constraint

The new generation of orbital projects is power-hungry in a way legacy satellites never were. A traditional communications satellite sips a few kilowatts. A commercial space station must power life support, laboratories, and manufacturing for years. An orbital data center converts watts directly into revenue — its business case is literally denominated in power. Electric propulsion trades power for propellant. Across every category, spacecraft power budgets are inflating by an order of magnitude, and the arrays, deployment structures, and power management hardware to feed them have become the pacing item.

The Commoditization Arc

Spacecraft subsystems follow a predictable maturation arc. Stage one: every mission engineers the component in-house, bespoke, at enormous cost — because no alternative exists. Stage two: specialist startups productize the component for early adopters willing to trade heritage for price and lead time. Stage three: the product becomes a catalog item with standard interfaces, published pricing, and volume manufacturing — a commodity in the industrial sense: not low-value, but standardized, interchangeable, and bought rather than built. Satellite buses walked this arc. So did green propulsion, reaction wheels, star trackers, and flat-panel user terminals.

Fogelson's valves-and-motors framing places deployable solar arrays at the transition from stage two to stage three. No spacecraft company machines its own valves or winds its own motors; those categories commoditized decades ago in adjacent industries. His bet is that power deployment hardware is next — that within a few years, designers will spec a deployable array from a catalog the way they spec a battery today, and the winners will be whoever is already producing at rate when the demand wave crests. Hence a Brooklyn factory targeting ten-plus units a day by the end of 2027, planned before the first flight qualification is even complete.

The Merchant Supplier Playbook

1. Pick a subsystem where physics is hard but the interface is simple — power, torque, heat, and data are clean boundaries that let customers integrate without co-engineering.
2. Win the reference design early — the first flight-qualified product with real heritage becomes the default spec that everyone writes requirements around.
3. Invest in manufacturing ahead of demand — in components, capacity is credibility; customers commit to suppliers who can deliver at their ramp rate.
4. Standardize ruthlessly — every custom variant erodes margin and slows the line; the catalog is the product.
5. Expand along the interface — a trusted power supplier can sell radiators and structures to the same customer, compounding share of the spacecraft.

What It Signals About the Industry

A maturing supply chain is the quiet infrastructure of every space boom. When founders can buy power, propulsion, structures, and avionics off the shelf, the capital and time needed to attempt a mission collapse — which multiplies the number of credible missions, which deepens demand for components, which justifies more supplier scale. This flywheel, not any single launch or raise, is what industrialization actually looks like. The $342.6 million in LOIs Beyond Reach reports is one data point; the more telling one is that customers increasingly describe power the way Fogelson does — as something they should not have to think about.

The BlacKnight Take

The unglamorous middle of the value chain is where the next cohort of great space companies is being built. Missions get the headlines, but merchant suppliers get the recurring revenue, the diversified customer base, and the pricing power of a bottleneck asset. For founders, the filter is simple: find the subsystem where demand is inflecting, physics forms a moat, and the interface is clean enough to productize — then out-manufacture everyone. Power is passing through exactly that window now. The valves-and-motors future is coming for most of the spacecraft; the only question is which suppliers own the catalog when it arrives.
