Electrify Everything: Span’s Big Bet on the Dumbest Box in the House

Consumers want the upgrades. The climate does too. But the electrical panel in the garage stands in the way.

EVs, heat pumps, induction stoves—electrification is becoming more attractive. The products are faster, cleaner, cheaper to run. But nearly 48 million U.S. homes still rely on outdated 100-amp service. That means expensive utility upgrades, long delays, and a halt to progress.

Arch Rao, former Tesla Energy product lead, built Span to fix the bottleneck. The Span Panel replaces the old breaker box with a connected, intelligent device that lets homeowners add electric appliances without triggering a full service upgrade. It works with solar, batteries, and EVs—and gives people visibility and control over their energy use for the first time.

Span is the upgrade that makes all the other upgrades possible. And with Span Edge, utilities can manage demand house by house, neighborhood by neighborhood—without building more poles and wires.

Span turns a forgotten piece of hardware into a platform for electrification—at home, and across the grid.
