The approximate operating cost for a natural gas generator using Egoli Gas is
around R2.00 to R2.16 per kilowatt-hour (kWh).
This cost is a general estimate and the actual amount you pay depends on several variables, including:
- Generator Efficiency: The actual efficiency of your specific generator model affects the final cost. Conventional generators tend to be more efficient when running closer to full capacity.
- Current Gas Price: Egoli Gas's maximum price for piped natural gas is regulated by the National Energy Regulator of South Africa (NERSA) and is adjusted quarterly based on factors like the cost of gas acquisition.
- Connection Charges: Egoli Gas charges a monthly connection fee, which should be factored into your overall energy expenses.
Cost Comparison
Using natural gas for power generation is generally considered more cost-effective than using petrol or diesel generators, both in terms of operating costs and the convenience of a continuous, piped supply (no refuelling needed).
- Natural Gas: ~R2.00 - R2.16/kWh
- LPG: ~R3.80/kWh
- Diesel: ~R5.00 - R7.00/kWh
- Petrol: ~R10.13/kWh (as of March 2024)
