Derivative Instruments and Hedging Activities Disclosure [Abstract]  
Derivatives, Policy XPLR uses derivative instruments (primarily interest rate swaps) to manage the interest rate cash flow risk associated with outstanding and expected future debt issuances and borrowings and to manage the physical and financial risks inherent in the sale of electricity. XPLR records all derivative instruments that are required to be marked to market as either assets or liabilities on its condensed consolidated balance sheets and measures them at fair value each reporting period. XPLR does not utilize hedge accounting for its derivative instruments. All changes in the interest rate contract derivatives' fair value are recognized in interest expense and the equity method investees' related activity is recognized in equity in earnings of equity method investees in XPLR's condensed consolidated statements of income (loss).
Fair Value Measurement of Derivative Instruments – The fair value of assets and liabilities are determined using either unadjusted quoted prices in active markets (Level 1) or other observable inputs (Level 2) whenever that information is available and using unobservable inputs (Level 3) to estimate fair value only when relevant observable inputs are not available. XPLR uses different valuation techniques to measure the fair value of assets and liabilities, relying primarily on the market approach of using prices and other market information for identical and/or similar assets and liabilities for those assets and liabilities that are measured at fair value on a recurring basis. Certain financial instruments may be valued using multiple inputs including discount rates, counterparty credit ratings and credit enhancements. XPLR’s assessment of the significance of any particular input to the fair value measurement requires judgment and may affect the placement of those assets and liabilities within the fair value hierarchy levels. Non-performance risk, including the consideration of a credit valuation adjustment, is also considered in the determination of fair value for all assets and liabilities measured at fair value. Transfers between fair value hierarchy levels occur at the beginning of the period in which the transfer occurred.

XPLR estimates the fair value of its derivative instruments using an income approach based on a discounted cash flows valuation technique utilizing the net amount of estimated future cash inflows and outflows related to the agreements. The primary inputs used in the fair value measurements include the contractual terms of the derivative agreements, current interest rates and credit profiles. The significant inputs for the resulting fair value measurement of interest rate contracts are market-observable inputs and the measurements are reported as Level 2 in the fair value hierarchy.
