Segment Reporting [Abstract]

Financial Data of Business Segments

Inter-segment billing for goods and services exchanged between segments is based upon tariffed or market-based prices of the provider. Such billing primarily consists of power sales, sale and transportation of natural gas, and renewable natural gas sales in the segments below, as well as charges from Electric to other segments for use of the shared capital assets of DTE Electric. For the prior periods, inter-segment billing also included the sale of reduced emissions fuel at DTE Vantage.
