Evaluation of Coal Combustion Residuals and Effluent Limitation Guideline Costs in West Virginia and Kentucky

Sierra Club
Project Complete

Synapse evaluated the installation of coal combustion residuals and effluent limitation guideline costs at existing coal plants in dockets before the Public Utilities Commissions in three power plants: the Amos and Mountaineer plants in West Virginia, owned by Appalachian Power Company (APC); and the Mitchell plant in West Virginia, co-owned by Kentucky Power (KPC) and Wheeling Power (WPC). Synapse updated the companies' renewable pricing and found that a scenario in which effluent limitation guideline investments were foregone and the plants were retired in 2028 was more economic than a scenario in which the plants continued operating until 2040.
