Acid rain legislation: its impact on electric utilities
The costs of impending legislation controlling power plant emissions to TVA utilities and their ratepayers are presented. Two approaches have been proposed for achieving SO/sub 2/ emission reductions. One would require the utilities to rely heavily on scrubbers; the second would give the utilities the flexibility to select the least cost method for reducing emissions. Using scrubbers, the average cost of SO/sub 2/ reduction would be $640 per ton removed. Using least-cost method, the cost would be $200.00 to $400.00 per ton removed. Scrubbers are the lower cost option at newer, more efficient plants which operate at base load and are located in areas where low-sulfur coal is not readily available. Low-sulfur coal is more economical for older plants which operate in an intermediate or peaking mode. If emission reductions of 8 million tons of SO/sub 2/ or less from coal-fired power plants are required, savings up to about $800 million per year would be achieved using a least-cost strategy. For emission reductions greater than 8 million tons, the saving decreases. At about 11 million tons, the costs are the same. 16 figures. (DMC)
