Debt Disclosure [Abstract] |
Short-term Borrowings and Long-term Debt | Short-term Borrowings and Long-term Debt Inventory Financing. CenterPoint Energy’s and CERC’s Natural Gas businesses have third-party AMAs associated with their utility distribution service in Indiana, Louisiana, Minnesota, Mississippi and Texas. The AMAs have varying terms, the longest of which expires in 2027. Pursuant to the provisions of the agreements, CenterPoint Energy’s and CERC’s Natural Gas either sells natural gas to the asset manager and agrees to repurchase an equivalent amount of natural gas throughout the year at the same cost, or simply purchases its full natural gas requirements at each delivery point from the asset manager. Certain of these transactions are accounted for as an inventory financing. CenterPoint Energy and CERC had $-0- and $11 million outstanding obligations related to the AMAs as of March 31, 2023 and December 31, 2022, respectively, recorded in Short-term borrowings on CenterPoint Energy’s and CERC’s Condensed Consolidated Balance Sheets.
