Property, Plant and Equipment [Abstract]

Presque Isle Power Plant

Pursuant to MISO's April 2018 approval of the retirement of the PIPP, these units were retired on March 31, 2019. The carrying value of the PIPP units was $167.2 million at June 30, 2019. This amount included the net book value of $178.5 million, which was classified as a regulatory asset on our balance sheets as a result of the retirement of the plant. In addition, an $11.3 million cost of removal reserve related to the PIPP units remained classified as a regulatory liability at June 30, 2019. After the retirement of the PIPP, a portion of the regulatory asset and related cost of removal reserve was transferred to UMERC for recovery from their retail customers. WE has FERC approval to continue to collect the carrying value of the PIPP units using the approved composite depreciation rates, in addition to a return on the remaining carrying value. However, this approval is subject to refund pending the outcome of settlement procedures. WE and UMERC will amortize the regulatory assets on a straight-line basis using the composite depreciation rates approved by the PSCW before the units were retired.

Severance Liability for Plant Retirements

We have evaluated future plans for our older and less efficient fossil fuel generating units and have retired several plants within the Wisconsin segment. In addition, a severance liability was recorded in other current liabilities on our balance sheets related to these plant retirements.
