Episode notes
Grid and Home Spare Capacity
- The average utilization rate of the U.S. distribution system is only around 42%.
- Homes and grids have significant spare capacity since they are built for rare peak loads, not constant use.
Invisible Load Throttling
- Span panels throttle loads briefly when demand peaks, usually about eight minutes per event.
- Most customers do not notice these brief throttling events, as no loads are fully turned off.
Utility-Controlled Deployment
- Utilities gain better control by deploying Span Edge panels at the meter rather than waiting for consumer-led installs.
- This allows targeted deployment in critical grid areas to avoid costly infrastructure upgrades.
