New Zealand Electricity Dept. is following up on a study that shows a combined cycle plant would cost some $75 million less than a 1400-MW gas-fired steam plant under consideration and would save enough fuel to supply another 200-MW plant for 25 years. Combined cycle efficiency is likely to range between 44 and 47 percent, compared with 38 percent at best for conventional steam plants of modern design. Competitive bid prices for oil-fired and gas-fired combined cycle plants suggest that the cost is 15 to 20 percent lower, with typical values on the order of $280 per kW installed versus $330 per kW for a steam station. Evaluations of economic tradeoffs show that combined cycle power is 6.5 to 10 percent cheaper than proposed steam plant power at fuel cost increases from $0.50 to $1.50 per million Btu.
