Organization, Consolidation and Presentation of Financial Statements [Abstract] |
GENERAL INFORMATION | GENERAL INFORMATION WEC Energy Group serves approximately 1.6 million electric customers and 2.9 million natural gas customers, and owns approximately 60% of ATC. As used in these notes, the term "financial statements" refers to the condensed consolidated financial statements. This includes the income statements, statements of comprehensive income, balance sheets, statements of cash flows, and statements of equity, unless otherwise noted. In this report, when we refer to "the Company," "us," "we," "our," or "ours," we are referring to WEC Energy Group and all of its subsidiaries. We consolidate on our balance sheets our majority-owned subsidiaries and reflect a noncontrolling interest for the portion of an entity that we do not own as a component of consolidated equity separate from the equity attributable to our shareholders. We acquired an 80% membership interest in Bishop Hill Energy III Holdings LLC on August 31, 2018, which owns 100% of Bishop Hill III. The noncontrolling interest that we reported as equity on our balance sheets as of September 30, 2018, relates to a minority interest held by a third party. See Note 2, Acquisitions, for more information. We have prepared the unaudited interim financial statements presented in this Form 10-Q pursuant to the rules and regulations of the SEC and GAAP. Accordingly, these financial statements do not include all of the information and footnotes required by GAAP for annual financial statements. These financial statements should be read in conjunction with the consolidated financial statements and footnotes in our Annual Report on Form 10-K for the year ended December 31, 2017. Financial results for an interim period may not give a true indication of results for the year. In particular, the results of operations for the three and nine months ended September 30, 2018, are not necessarily indicative of expected results for 2018 due to seasonal variations and other factors. In management's opinion, we have included all adjustments, normal and recurring in nature, necessary for a fair presentation of our financial results.
