| Prerequisite | Type | Confidence | Evidence level | Note | Sources |
|---|---|---|---|---|---|
| Alternating-Current Power Systems (alternating_current_power) | enabling | 68% | expert_inference | Alternating-Current Power Systems provides a capability that enables this technology without being the only possible path. |
|
| Electric Power Meters (electric_power_meters) | enabling | 68% | expert_inference | Electric Power Meters provides a capability that enables this technology without being the only possible path. | No sources recorded. |
| Electrical Grid (Early Distribution) (electrical_grid_early_distribution) | historical_predecessor | 75% | expert_inference | Electrical Grid (Early Distribution) is an earlier historical predecessor or foundation, not a one-to-one engineering dependency. |
