Episode notes
Founder's Renewable Energy Origins
- Arch Rao recounts his background at Tesla Energy and in renewables which shaped Span's mission.
- That experience led him to pursue digital power controls as an alternative to massive grid upgrades.
Avoiding Costly Service Upgrades
- Most homes rarely hit their service capacity, so real-time load management can avoid costly utility upgrades.
- Span throttles or pauses appliances for short windows to prevent service upgrades with minimal user impact.
Panel As The Natural Power Router
- The electrical panel is the natural leverage point for power optimization because everything connects there.
- Span uses that position to manage instantaneous demand better than batteries alone can.
