Cayuga Station

Cayuga Satation
Capacity: 1,040 megawatts (Winter Peak Capacity)
Location: Vermillion County, Indiana
Commercial Date: 1970
Status: Operating

Cayuga Station is a three-unit generating facility built between 1970 and 1993. Units 1 and 2 have been equipped with scrubbers to reduce the station’s sulfur dioxide emissions by approximately 95%. Duke Energy is currently investing $400 million at Cayuga to install selective catalytic reduction units that effectively reduce nitrogen oxides, as well as other equipment to enhance mercury removal.

Steam and power is supplied to the plant’s neighbor, a packaging product manufacturer whose raw material is 100% recycled pulp products. The plant also features a 35-acre wetland area that was created in partnership with the U.S. Fish and Wildlife Agency.

Learn more about our emergency action plans for coal ash facilities. Ash basins continue to operate safely and are highly regulated. Removing water and permanently closing basins, work that is already planned or underway, adds an additional margin of safety. Inundation maps are planning tools that illustrate a worst-case scenario and depict the areas that could be impacted in the unlikely event of a complete dam failure.

2017 - 2018 

Work is underway to prepare for safely closing ash basins. This includes designing and constructing new retention basins for water management; installing state-of-the-art wastewater treatment systems; and installing new equipment to manage all coal ash dry rather than sending it to ash basins. While the work itself will occur on plant property, neighbors may notice periodic equipment deliveries and an increase in construction activities.
