## Summary

Arch Rao, Founder and CEO of Span, explains how his company’s smart electrical panel enables homeowners to monitor, control, and optimize energy use down to the circuit level, avoiding costly $15,000–$25,000 service upgrades. Drawing on his experience at Tesla Energy, Rao details how Span’s intelligent load management allows homes to adopt EV chargers, solar, and batteries without upgrading the grid. He discusses the evolution from a consumer-led product to a utility-scale infrastructure asset, highlighting partnerships with utilities like PG&E and the importance of interoperable, aesthetically designed hardware. Rao emphasizes the need for deep system-level engineering to navigate supply chain issues and scale production across 50 states.
