The coal-fired East Bend power plant of Duke Energy Kentucky ran at a capacity factor of nearly 87% in the November 2015-April 2016 period, with 745,316 tons of coal burn during the period, said this Duke Energy (NYSE: DUK) subsidiary in a fuel report filed Aug. 26 at the Kenbtucky Public Service Commission.
Suppliers during the period included Alliance Coal LLC, Alpha Coal Sales LLC and Armstrong Coal Co. Details are given on term contracts that were in place during the November 2015-April 2016 fuel review period. For example:
- there is a contract with Alliance Tunnel Ridge for coal out of the Tunnel Ridge mine in northern West Virginia that was executed on Jan. 8 of this year, runs from January 2016 through December 2017, and calls for 100,000 tons in 2016 and 400,000 tons in 2017; and
- there is a contract with Alpha Coal Sales for coal out of the Cumberland operation in Pennsylvania, that was executed on Jan. 8 of this year, that runs from January 2016 through December 2017, and calls for 250,000 tons in 2016 and 350,000 tons in 2017.
As of April 30, total station coal inventory at East Bend was 287,348 tons, or 44 days. The number of days of supply is computed by dividing an ending coal inventory figure stated in tons by the Full Load Burn figure of 6,500 tons per day. The inventory target is an annual average of 40 days compared to the 44 days of inventory on April 30.
Noted the filing about PJM Interconnection standards: “Duke Energy Kentucky has seven generating units, East Bend 2 and Woodsdale 1-6, that will be subject to the PJM Capacity Performance standards starting June 1, 2019. Capacity Performance focuses on two primary parameters, fuel availability, and mechanical reliability. From a fuel availability perspective, East Bend 2, by nature of being a coal fired unit with onsite fuel, is compliant with Capacity Performance requirements. Woodsdale Station, with no firm fuel supply agreement and limited alternate fuel supply, does not currently meet the Capacity Performance fuel availability criteria. Duke Kentucky is currently evaluating fuel alternatives for Woodsdale Station, including; firm natural gas transportation agreements, redundant pipeline connections, and additional onsite dual fuel capabilities. Duke Kentucky is also evaluating investments in both stations that will enhance mechanical reliability.”
