Cost Avoidance
Annual savings vs Eskom
UtCS has been appointed as the strategic implementation partner to assist the participating municipalities in achieving NERSA-defined Sustainable Electricity Trading Status. This status requires municipalities to achieve an Electricity Price Margin (EPM) of minimum 60% after settling Bulk Supply Costs.
Strategic Objective
Deploy innovatively and strategically placed Nano-Grids to impose maximum cost avoidance, enabling municipalities to achieve the 60% EPM benchmark.
Financial Impact
Through TOU arbitrage and maximum demand reduction, achieve >40% total cost avoidance, directly improving each municipality's financial sustainability.
| Performance Indicator | Benchmark | Acceptable Range |
|---|---|---|
| Electricity Price Margin (%) | 60% | 58% - 62% |
| Bulk Purchase Cost / Total Expenditure (%) | 75% | 58% - 78% |
| Energy Losses (%) | 10% | 5% - 12% |
| Revenue Collection Rate (%) | 95% | 95% |
| Repairs & Maintenance (% of revenue) | 6% | 6% - 15% |
| Net Surplus Margin (%) | 15% | 10% - 20% |
