The cost for construction of a desulfurization system for flue gas from boilers at a 600 MW power plant was estimated to be $250 million. If a similar system for a smaller plant had a cost of $55 million and the exponent in the cost-capacity equation is 0.67, what is the size of the smaller plant that served as the basis for the cost projection?
