Regulated Operations [Abstract]
Regulatory Assets and Liabilities [Policy Text Block]	Our regulated utility operations are subject to accounting standards for the effects of certain types of regulation. Regulatory assets represent incurred costs that have been deferred as they are probable for recovery in customer rates. Regulatory liabilities represent obligations to make refunds to customers and amounts collected in rates for which the related costs have not yet been incurred. The Company assesses quarterly whether regulatory assets and liabilities meet the criteria for probability of future recovery or deferral. With the exception of the regulatory asset for Boswell Units 1 and 2 net plant and equipment, no other regulatory assets are currently earning a return. The recovery, refund or credit to rates for these regulatory assets and liabilities will occur over the periods either specified by the applicable regulatory authority or over the corresponding period related to the asset or liability.
Recognition of Regulatory Outcomes Policy	Impacts of regulatory outcomes that are determined subsequent to the balance sheet date, and prior to issuance of the financial statements, are recognized in the financial statements as of the balance sheet date.
