Gas undercuts diesel generation by more than half — and emits less carbon

Eskom generation cost by fuel type, R/MWh; LNG shown at midpoint of estimated R2 200–R2 800/MWh range

~50%

cheaper fuel delivered cost for LNG vs diesel (R/GJ)

26%

lower carbon intensity for gas vs diesel generation

Diesel open-cycle gas turbines are Eskom's most expensive backup source by a wide margin. Regasified LNG delivers the same megawatt-hour at a fraction of the cost — making gas a decisive improvement on both cost and emissions grounds, not a marginal one.
