Segment Reporting [Abstract] |
Segment and Related Information | (PPL) PPL is organized into two segments: Kentucky Regulated and Pennsylvania Regulated. PPL's segments are segmented by geographic location. The Kentucky Regulated segment consists primarily of LG&E's and KU's regulated electricity generation, transmission and distribution operations, as well as LG&E's regulated distribution and sale of natural gas. The Pennsylvania Regulated segment includes the regulated electricity transmission and distribution operations of PPL Electric. "Corporate and Other" primarily includes financing costs incurred at the corporate level that have not been allocated or assigned to the segments, certain other unallocated costs, as well as the financial results of Safari Energy, which is presented to reconcile segment information to PPL's consolidated results. For the periods ended December 31, 2020 and 2019, these amounts have been adjusted for certain costs that were previously included in the U.K. Regulated segment. On March 17, 2021, PPL WPD Limited entered into a share purchase agreement to sell PPL's U.K. utility business, which substantially represented PPL's U.K. Regulated segment. As a result, PPL determined segment information for the U.K. Regulated segment would no longer be provided beginning with the March 31, 2021 Form 10-Q. The sale of the U.K. utility business was completed on June 14, 2021. See Note 9 for additional information. Income Statement data for the segments and reconciliation to PPL's consolidated results for the years ended December 31 are as follows:
