Final Order Entered: 1. Duke Kentucky’s request for authorization to establish a regulatory asset for the expenses incurred related to engineering and design for its withdrawn CPCN Applications is granted. 2. In the event that Duke Kentucky is still required to perform the MATS project as a result of the final decision regarding the U.S. EPA’s proposal to repeal the 2024 MATS standard, then Duke Kentucky shall record only the approved portion of the actual Application costs associated only with the Limestone Conversion Project, not associated with the work needed to comply with MATS, to the regulatory asset. 3. The regulatory asset accounts established in this case are for accounting purposes only. 4. Duke Kentucky shall, within 14 days of service of this Order, file with the Commission the accounting entries made on its books to effectuate the creation of the regulatory assets. 5. Any documents filed in the future pursuant to ordering paragraph 4 herein shall reference this case number and shall be retained in the post-case correspondence file. 6. The amount, if any, of the regulatory assets authorized herein that is to be amortized and included in rates shall be determined in Duke Kentucky’s next base rate case. 7.
