It also includes other kinds of accounts that have the general characteristics of demand deposits in that the Entity may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that de finition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Compensating balance arrangements that do not legally restrict the withdrawal or usage of cash amounts may be reported as Cash and Cash Equivalents, while legally restricted deposits held as compensating balances against borrowing arrangements, contracts entered into with others, or company statements of intention with regard to particular deposits should not be reported as cash and cash equivalents.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Statement of Financial Accounting Standard (FAS) -Number 95 -Paragraph 7, 26 Reference 2: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Statement of Financial Accounting Standard (FAS) -Number 95 -Paragraph 8, 9 Reference 3: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Statement of Financial Accounting Standard (FAS) -Number 95 -Paragraph 7 -Footnote 1 Reference 4: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Regulation S-X (SX) -Number 210 -Section 02 -Paragraph 1 -Article 5 falsefalse11false0us-gaap_AccountsReceivableNetCurrentus-gaaptruedebitinstantNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalselabel1truefalsefalse15090000001509falsefalsefalsefalsefalse2truefalsefalse14310000001431falsefalsefalsefalsefalseMoneta ryxbrli:monetaryItemTypemonetaryAmount due from customers or clients, within one year of the balance sheet date (or the normal operating cycle, whichever is longer), for goods or services (including trade receivables) that have been delivered or sold in the normal course of business, reduced to the estimated net realizable fair value by an allowance established by the entity of the amount it deems uncertain of collection.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Regulation S-X (SX) -Number 210 -Section 02 -Paragraph 3 -Subparagraph a(1) -Article 5 Reference 2: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Regulation S-X (SX) -Number 210 -Section 02 -Paragraph 4 -Article 5 falsefalse12false0nee_OtherReceivablesNetneefalsedebitinstantNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalseterselabel1truefalsefalse10730000001073falsefalsefalsefalsefalse2truefalsefalse816000000816falsefalsefalsefalsefalseMonetaryxbrli:monetaryItemTypemonetaryNo definition available.No authoritative reference available.falsefalse13false0nee_MaterialsSuppliesAndFossilFuelInventoryneefalsedebitinstantNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalseterselabel1truefalsefalse857000000857falsefalsefalsefalsefalse2truefalsefalse877000000877falsefalsefalsefalsefalseMonetaryxbrli:monetaryItemTypemonetaryNo definition available.No authoritative reference available.falsefalse14true0nee_RegulatoryAssetsCurrentAbstractneefalsenadurationNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalseterselabel1falsefalsefalse00falsefalsefalsefalsefalse2falsefalsefalse00falsefalsefalsefalsefalseOtherxbrli:stringItemTypestringNo definition available.falsefalse15false0nee_CurrentRegulatoryAssetsDeferredClauseAndFranchiseExpensesneefalsedebitinstantNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalseterselabel1truefalsefalse368000000368falsefalsefalsefalsefalse2truefalsefalse6900000069falsefalsefalsefalsefalseMonetaryxbrli:monetaryItemTypemonetaryNo definition available.No authoritative reference available.falsefalse16false0nee_CurrentRegulatoryAssetsDerivativesneefalsedebitinstantCarrying amount as of the balance sheet date of deferred derivatives of regulated entities that are expected to be recovered...falsefalsefalsefalsefalsefalsefalsefalsefalsefalseterselabel1truefalsefalse236000000236falsefalsefalsefalsefalse2truefalsefalse6800000068falsefalsefalsefalsefalseMonetaryxbrli:monetaryItemTypemonetaryCarrying amount as of the balance sheet date of deferred derivatives of regulated entities that are expected to be recovered through revenue sources within one year or the normal operating cycle, if longer. Such costs are capitalized if they meet both of the following criteria: a. It is probable that future revenue in an amount at least equal to the capitalized cost will result from inclusion of that cost in allowable costs for rate-making purposes. b. Based on available evidence, the future revenue will be provided to permit recovery of the previously incurred cost rather than to provide for expected levels of similar future costs. If the revenue will be provided through an automatic rate-adjustment clause, this criterion requires that the regulator's intent clearly be to permit recovery of the previously incurred cost.No authoritative reference avai lable.falsefalse17false0nee_CurrentRegulatoryAssetsOtherneefalsenainstantNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalseterselabel1truefalsefalse8200000082falsefalsefalsefalsefalse2truefalsefalse7200000072falsefalsefalsefalsefalseMonetaryxbrli:monetaryItemTypemonetaryNo definition available.No authoritative reference available.falsefalse18false0nee_CurrentAssetsDerviativesneefalsenainstantFair values as of the balance sheet date for all assets resulting from contracts that meet the criteria of being accounted...falsefalsefalsefalsefalsefalsefalsefalsefalsefalseterselabel1truefalsefalse506000000506[1]falsefalsefalsefalsefalse2truefalsefalse357000000357[1]falsefalsefalsefalsefalseMonetaryxbrli:monetaryItemTypemonetaryFair values as of the balance sheet date for all assets resulting from contracts that meet the criteria of being accounted for as derivative instruments and which are expected to be converted into cash or otherwise disposed of within a year or the normal operating cycle, if longer, net of the effects of master netting arrangements and net of obligations to return margin cash collateral in accordance with FASB Staff Position (FSP) FIN 39-1, "Amendment of FASB Interpretation No. 39."No authoritative reference available.falsefalse19false0us-gaap_OtherAssetsCurrentus-gaaptruedebitinstantNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalseterselabel1truefalsefalse325000000325falsefalsefalsefalsefalse2truefalsefalse409000000409falsefalsefalsefalsefalseMonetaryxbrli:monetaryItemTyp emonetaryAggregate carrying amount, as of the balance sheet date, of current assets not separately presented elsewhere in the balance sheet.
