Critical Care Can't Afford Downtime
Pretoria North Medical Centre operates diagnostic equipment, pharmacy cold storage, patient monitoring systems, and general building services — all of which depend on reliable electricity. Load shedding presented a direct risk to patient care and operational continuity.
Specific pain points:
- Load shedding disrupting appointment schedules and diagnostic equipment
- Generator costs escalating with increased outage frequency
- Pharmacy cold chain integrity at risk during extended outages
- Rising Eskom tariffs increasing operating costs in an already margin-pressured healthcare environment
- Need for a phased approach to manage cash flow while delivering immediate results
Solar + Battery — Designed for Healthcare
Gentricity designed a phased system that addressed the medical centre's most critical needs first, with the ability to expand:
System specifications:
- 93kWp solar panel array covering available roof space
- 200kWh lithium battery storage for load shedding protection
- Intelligent energy management system prioritising critical medical loads
- Real-time monitoring with automated alerts
- Seamless integration with existing electrical infrastructure
Why this configuration:
- Solar panels generate power during clinic operating hours, directly offsetting grid consumption
- Battery storage covers critical loads during load shedding periods (estimated 4-6 hours backup for essential systems)
- The system was designed in phases to match the centre's budget cycle while delivering immediate benefits
Results (Estimated based on system specifications and industry benchmarks)
| Metric | Estimated Value |
|---|---|
| Electricity cost reduction | 50-60% of previous bill |
| Load shedding coverage | 4-6 hours for critical loads |
| Generator use reduction | 70-80% decrease in generator runtime |
| Estimated annual savings | R180,000 - R250,000 |
| Payback period | 4-5 years (before Section 12B benefit) |
| System monitoring | Real-time, 24/7 |
Note: Figures are estimates based on system size and SA commercial solar benchmarks. Actual results may vary.
