Segment Reporting |
Segment Reporting As part of perfecting the integrated model, in which the majority of the Company’s generation serves its retail customers, the Company began managing its operations based on the combined results of the retail and wholesale generation businesses with a geographical focus in 2020. As a result, the Company changed its business segments from Retail and Generation to Texas, East and West/Other beginning in the first quarter of 2020, as further described in Note 1, Nature of Business. The Company's updated segment structure reflects how management currently makes financial decisions and allocates resources The financial information for the three and nine months ended September 30, 2019 was recast to reflect the current segment structure. In February 2019, as described in Note 4, Acquisitions, Discontinued Operations and Dispositions, the Company completed the sales of the South Central Portfolio and Carlsbad. The financial information for the three and nine months ended September 30, 2019 presented below reflects the presentation of these entities as discontinued operations within the corporate segment. NRG’s chief operating decision maker, its chief executive officer, evaluates the performance of its segments based on operational measures including adjusted earnings before interest, taxes, depreciation and amortization, or Adjusted EBITDA, free cash flow and allocation of capital, as well as net income/(loss). | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Three months ended September 30, 2020 | (In millions) | | Texas | | East | | West/Other | | Corporate | | Eliminations | | Total | Operating revenues | | $ | 1,992 | | | $ | 693 | | | $ | 122 | | | $ | — | | | $ | 2 | | | $ | 2,809 | | Depreciation and amortization | | 49 | | | 34 | | | 9 | | | 7 | | | — | | | 99 | | Impairment losses | | — | | | — | | | 29 | | | — | | | — | | | 29 | | | | | | | | | | | | | | | | | | | | | | | | | | | | Equity in earnings of unconsolidated affiliates | | — | | | — | | | 36 | | | — | | | — | | | 36 | | | | | | | | | | | | | | | Income/(loss) from continuing operations before income taxes | | 288 | | | 149 | | | 17 | | | (113) | | | — | | | 341 | | Income/(loss) from continuing operations | | 288 | | | 149 | | | 17 | | | (205) | | | — | | | 249 | | | | | | | | | | | | | | | | | | | | | | | | | | | | Net income/(loss) attributable to NRG Energy, Inc | | $ | 288 | | | $ | 149 | | | $ | 17 | | | $ | (205) | | | $ | — | | | $ | 249 | |
