Fair Value Disclosures [Abstract]
Derivatives, Policy [Policy Text Block]	Accounting guidance requires derivative instruments and hedging activities to be recognized at fair value on the balance sheet. Cleco may elect the normal purchase and normal sale scope exception to the application of fair value accounting for these instruments and activities if they meet certain accounting criteria. Cleco’s Energy Market Risk Management Policy authorizes hedging against commodity price risk with physical or financially settled derivative instruments. For Cleco Power, due to regulatory treatment, associated mark-to-market adjustments for changes in fair value of recognized derivatives are generally recognized in Accumulated deferred fuel on the balance sheet. For Cleco Cajun, the changes in the fair value of recognized derivatives are recorded in current earnings.Cleco Power’s natural gas derivative contracts are marked-to-market with the resulting unrealized gain or loss recorded as a component of Accumulated deferred fuel on the balance sheet. At settlement, realized gains or losses are included in Cleco Power’s FAC and reflected on customer’s bills as a component of the fuel charge. Cleco Cajun’s unrealized gains or losses as well as realized gains or losses at settlement are recorded on the income statement as a component of fuel expense.
