OG&E has an intercompany borrowing agreement with OGE Energy whereby OG&E has access to up to $400 million of OGE Energy's revolving credit amount.  Effective July 29, 2013, OG&E extended the termination date of this agreement to December 13, 2017.  At June 30, 2013, there were no intercompany borrowings under this agreement. OG&E has a $400 million revolving credit facility which is available to back up OG&E's commercial paper borrowings and to provide revolving credit borrowings.  This bank facility can also be used as a letter of credit facility. At June 30, 2013, there was $2.1 million supporting letters of credit at a weighted-average interest rate of 0.53 percent. At June 30, 2013, OG&E had less than $0.1 million in cash and cash equivalents. </div><div style="line-height:120%;text-indent:48px;font-size:8pt;"> </div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;">In December 2011, OG&E entered into an unsecured five-year revolving credit agreement for $400 million. This credit facility contains an option, which may be exercised up to two times, to extend the term for an additional year, subject to consent of a specified percentage of the lenders. Effective July 29, 2013, OG&E utilized one of these one-year extensions, and received consent from all of the lenders, to extend the maturity of its credit agreement to December 13, 2017. </div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"> </div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;">OGE Energy's and OG&E'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 OGE Energy's and OG&E's credit facilities could cause annual fees and borrowing rates to increase if an adverse ratings impact occurs. The impact of any future downgrade could include an increase in the costs of OGE Energy's and OG&E's short-term borrowings, but a reduction in OGE Energy's and OG&E's credit ratings would not result in any defaults or accelerations.  Any future downgrade OG&E could also lead to higher long-term borrowing costs and, if below investment grade, would require OG&E to post cash collateral or letters of credit. </div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:8pt;"> </div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;">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 million in short-term borrowings at any one time for a two-year period beginning January 1, 2013 and ending December 31, 2014. </div></div>falsefalsefalsenonnum:textBlockItemTypenaThe entire disclosure for short-term debt.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Regulation S-X (SX) -Number 210 -Section 02 -Paragraph 19 -Article 5 Reference 2: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Regulation S-X (SX) -Number 210 -Section 03 -Paragraph 16 -Article 7 Reference 3: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 944 -SubTopic 210 -Section S99 -Paragraph 1 -Subparagraph (SX 210.7-03.16) -URI http://asc.fasb.org/extlink&oid=6879938&loc=d3e572229-122910 Reference 4: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 942 -SubTopic 210 -Section S99 -Paragraph 1 -Subparagraph (SX 210.9-03.13) -URI http://asc.fasb.org/extlink&oid=6876686&loc=d3e534808-122878 Reference 5: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Regulation S-X (SX) -Number 210 -Section 03 -Paragraph 13 -Article 9 Reference 6: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 210 -SubTopic 10 -Section S99 -Paragraph 1 -Subparagraph (SX 210.5-02.19) -URI http://asc.fasb.org/extlink&oid=6877327&loc=d3e13212-122682 false0Short-Term Debt and Credit FacilityfalseShort-Term Debt and Credit FacilityUnKnownUnKnownUnKnownUnKnowntruefalsefalseSheethttp://www.oge.com/role/ShortTermDebtAndCreditFacility12
