During the latest fuel review period for Louisville Gas and Electric, the utility shut out the last coal-fired capacity at its Cane Run power plant and relied heavily on the replacement, gas-fired Unit 7 at Cane Run.
Louisville Gas and Electric filed on Feb. 19 with the Kentucky Public Service Commission the data needed for its latest fuel cost review case.
For the May-October 2015 fuel review period, the plants ran this way. Trimble County values reflect 100% of the unit. Trimble County 2 is owned by sister utility Kentucky Utilities (60.75%), LG&E (14.25%) and two other parties. Capacity factor calculations for Cane Run Units 4 and 5 include operating hours from May 1, 2015, through June 30, 2015, when those units were shut.
- Cane Run, 63,703 tons coal burned, 13,133 tons coal received, 116,705 net MWH generation, 24.7% capacity factor;
- Mill Creek, 1,715,453 tons burned, 1,812,459 tons received, 3,900,893 net MWH, 60.3% capacity factor;
- Trimble County High Sulfur (HS), N/A, 1,853,673 tons coal received, N/A, N/A;
- Trimble County Powder River Basin (PRB), N/A, 312,204 tons received, N/A, N/A;
- Trimble County Unit 1, 734,238 tons burned, N/A, 1,566,369 net MWH, 69.5% capacity factor; and
- Trimble County Unit 2, 1,239,538 tons burned, N/A, 2,890,778 net MWH, 89.4% capacity factor.
During the review period, Cane Run Unit 4 and Cane Run Unit 5 ceased operation as of the end of June 2015. Prior to the review period, Cane Run Unit 6 also ceased operation. All coal generation at Cane Run has now ceased. The addition of the new-gas-fired Cane Run Unit 7, its position as first in dispatch, resulting from high efficiency and the current price of natural gas, has lessened the operations of coal units within the fleet, the filing noted.
As of Oct. 31, 2015, the coal inventories were:
- Mill Creek, 793,645 tons, which is 54 days of supply against a target of 20-43 days; and
- Trimble County, 264,122 tons, which is 49 days against a target of 21-44 days. Trimble County coal inventory includes both high sulfur coal, which is used in Units 1 and 2, and PRB coal, which is used only in Unit 2.
