Short-term Debt [Abstract]  
Short-Term Debt and Credit Facilities Short-Term Debt and Credit Facilities
 
The Company holds short-term debt through revolving credit facilities and term credit agreements maturing in one year or less. As of September 30, 2020, the Company had no short-term debt as compared to $112.0 million of short-term debt at December 31, 2019.

The Company borrows on a short-term basis, as necessary, by the issuance of commercial paper and borrowings under its revolving credit agreements and term credit agreement. In April 2020, the Company entered into a $75.0 million floating rate unsecured one-year term credit agreement and borrowed the full $75.0 million, in order to preserve financial flexibility in response to COVID-19. Advances under this agreement were used to refinance existing indebtedness and for working capital and general corporate purposes of the Company. The term credit agreement contained substantially the same covenants as the Company's existing $450.0 million revolving credit agreement. In September 2020, the Company repaid the $75.0 million borrowed under the term credit agreement.

The following table provides information regarding the Company's revolving credit agreements at September 30, 2020.

The Company's ability to access the commercial paper market could be adversely impacted by a credit ratings downgrade or major market disruptions. Pricing grids associated with the Company's credit facilities could cause annual fees and borrowing rates to increase if an adverse rating impact occurs. The impact of any future downgrade could include an increase in the costs of the Company's short-term borrowings, but a reduction in the Company's credit ratings would not result in any defaults or accelerations. Any future downgrade could also lead to higher long-term borrowing costs and, if below investment grade, would require the Company to post collateral or letters of credit.
 
OG&E must obtain regulatory approval from the FERC in order to borrow on a short-term basis. OG&E has the necessary regulatory approvals to incur up to $800.0 million in short-term borrowings at any one time for a two-year period beginning January 1, 2019 and ending December 31, 2020. OG&E has requested renewal of this authority for an additional two-year period and expects to receive approval prior to the expiration of its current authority.
