Table 6 Cost estimates for emission-neutral power plants ($/MWh)

From: The role of natural gas as a primary fuel in the near future, including comparisons of acquisition, transmission and waste handling costs of as with competitive alternatives

Plant type Levelised capital costs: over 20 yrs ($/MWh) O&M costs (variable and fixed) ($/MWh) Total fuel price ($/MWh)* Total cost† ($/MWh) (CO2 = $5) Rank 1 (CO2 = $0) Rank 2 (CO2 = $5) Rank 3‡ (CO2 = $10)
Wind (50MW) 19 10 - 29 2 1 1
Coal (400 MW) 9 7 11 34 1 2 2

  1. *Coal price = $1.21/million BTU (about $25/short ton), gas price = $4/million BTU; † includes CO2, SO2, NOx costs (see Table 2); ‡The costs for opertaing a coal unit and a CC are approximately equal at $10/ton CO2
