Energy & Materials / Power
Design the power system for the service promise
The technology mix follows the load, outage cases, power quality, autonomy, restoration time, climate, maintenance, fuel, interconnection, and expansion curve. Solar plus batteries is not assumed to meet mission uptime.
Site-specific engineering required
Evidence matrix
Power stack
| Tier | Function | Evidence before claim |
|---|---|---|
| Utility or primary generation | Serve normal load economically | Capacity letter, interconnection study, tariff, and service agreement |
| On-site generation | Diversify supply and reduce cost or emissions | Resource study, production model, permits, and operating plan |
| UPS and battery storage | Bridge outages, stabilize quality, and shift energy | Load profile, dispatch model, safety study, degradation model, and acceptance test |
| Backup supply | Support extended loss events | Autonomy, logistics, emissions, maintenance, and replenishment plan |
| Energy controls | Coordinate sources, loads, and graceful degradation | Control narrative, simulations, cyber assessment, and drills |
Operating sequence
Reliability standard
- 01
Separate loads
Keep critical control load distinct from flexible compute load.
- 02
Model redundancy
Use N+1 or 2N only when customer service level and economics justify it.
- 03
Schedule with energy
React before battery state or thermal headroom reaches critical thresholds.
- 04
Test transitions
Exercise black start, islanding, synchronization, and recovery where designed.
- 05
Measure service
Report availability at the service boundary, not equipment uptime alone.
