Unsustainable Municipal
Electricity Margins
South African municipalities face a critical challenge: the traditional electricity trading model leaves almost no margin for sustainable operations and infrastructure investment.
Razor-Thin Margins
With Eskom bulk purchase at R2.39/kWh and municipal selling at R2.65/kWh, municipalities earn only R0.26 per unit - a margin of just 9.8%.
Rising Eskom Tariffs
Annual tariff increases of 12-13% from Eskom squeeze margins further, while NERSA limits municipal price increases to only 5-7% per year.
Infrastructure Pressure
Low margins mean municipalities cannot invest in grid maintenance, renewable integration, or service delivery improvements.

The Bottom Line
For every 12,614 kWh of electricity traded, the municipality earns only R3,313.20 under the traditional model - barely enough to cover administrative costs.
