Restructuring and Related Activities [Abstract]  
Restructuring Expense
During 2015 and 2016, we initiated and implemented certain organizational changes to simplify our corporate structure, improve our operational efficiencies and implement a strategy for sustainable, long-term stockholder value creation through financially disciplined development, construction, operation and investment.  As a result of these efforts, we recorded $6 million and $7 million of restructuring charges and other costs associated with restructuring and operational efficiency initiatives during the three months ended March 31, 2017 and 2016, respectively, for which the majority of these charges required, or will require, cash expenditure. Included in these amounts are $3 million and $6 million for share-based compensation during the three months ended March 31, 2017 and 2016, respectively.  All charges were recorded within the line item entitled “restructuring expense” on our Consolidated Statements of Operations and substantially all related to severance and other employee-related costs. As of both March 31, 2017 and December 31, 2016, we had $6 million of accrued restructuring charges and other costs that were recorded as part of accrued liabilities on our Consolidated Balance Sheets.  Organizational initiatives have been completed as of March 31, 2017.
