CY2012Q3	us-gaap	Factors Used To Identify Entitys Reportable Segments FactorsUsedToIdentifyEntitysReportableSegments	During the first quarter of 2012, the Company completed its operational management and reporting restructuring. The management reporting structure is organized along two lines of business – Generation and Utilities, each led by a Chief Operating Officer. The segment reporting structure primarily uses the Company’s management reporting structure as its foundation to reflect how the Company manages the business internally with further aggregation by geographic regions to provide better socio-political-economic understanding of our business. For the three and nine months ended September 30, 2012, the Company applied the segment reporting accounting guidance, which provides certain quantitative thresholds and aggregation criteria. The Company concluded that Tietê, our 2,663 MW hydro generation business in Brazil, met the quantitative thresholds to require separate presentation. As such, an additional reportable segment which consists solely of the results of Tietê is now reported as Generation – Tietê. Tietê was formerly reported within the Latin America – Generation segment. The previously disclosed Latin America – Generation segment is now reported as Generation – Latin America – Other and, with the exception of Tietê, includes the results of all remaining businesses as previously reported. All prior period results have been retrospectively revised to reflect the new segment reporting structure. The Company has increased from six to the following seven reportable segments: •        Generation – Latin America – Other; •        Generation – Tietê; •        Generation – North America; •        Generation – Europe; •        Generation – Asia; •        Utilities – Latin America; •        Utilities – North America. Corporate and Other—The Company’s Europe Utilities, Africa Utilities, Africa Generation, Wind Generation operating segments and other climate solutions and renewables projects are reported within “Corporate and Other” because they do not meet the criteria to allow for aggregation with another operating segment or the quantitative thresholds that would require separate disclosure under segment reporting accounting guidance. None of these operating segments are currently material to our presentation of reportable segments, individually or in the aggregate. AES Solar and certain other unconsolidated businesses are accounted for using the equity method of accounting; therefore, their operating results are included in “Net Equity in Earnings of Affiliates” on the face of the Condensed Consolidated Statements of Operations, not in revenue or gross margin. “Corporate and Other” also includes corporate overhead costs which are not directly associated with the operations of our seven reportable segments and other intercompany charges such as self-insurance premiums which are fully eliminated in consolidation. The Company uses adjusted gross margin, a non-GAAP measure, to evaluate the performance of its segments. Adjusted gross margin is defined by the Company as gross margin plus depreciation and amortization less general and administrative expenses. Total revenue includes intersegment sales related to the transfer of electricity from generation plants to utilities within Latin America. No material intersegment revenue relationships exist between other segments. Corporate allocations include certain self-insurance activities which are reflected within segment adjusted gross margin. All intra-segment activity has been eliminated with respect to revenue and adjusted gross margin within the segment. Intersegment activity has been eliminated within the total consolidated results. Asset information for businesses that were discontinued or classified as held for sale as of September 30, 2012 is segregated and is shown in the line “Discontinued Businesses” in the accompanying segment tables.
