Segment Reporting [Line Items]  
Business Segments BUSINESS SEGMENTS
Operating segments are components of an enterprise that engage in business activities from which it may earn revenue and incur expenses, for which separate financial information is available, and is evaluated regularly by the chief operating decision maker in assessing performance and deciding how to allocate resources. All of AES Ohio’s current business consists of the transmission, distribution and sale of electric energy, and therefore AES Ohio had only one reportable segment, led by our Chief Executive Officer and Chief Financial Officer, who, collectively, are the Chief Operating Decision Maker. The primary segment performance measures are income / (loss) before income tax and net income / (loss) as management has concluded that these measures best reflect the underlying business performance of AES Ohio and are the most relevant measures considered in AES Ohio's internal evaluation of the financial performance of its segment. See Note 1, "Overview and Summary of Significant Accounting Policies" for further information on AES Ohio.

The following tables present financial information for AES Ohio’s reportable business segment:
