BASIS OF PRESENTATION [Abstract]
BASIS OF PRESENTATION	1. BASIS OF PRESENTATION
	We are a limited partner of Enbridge Energy Partners, L.P., which we refer to as the Partnership, through our ownership of i-units, a special class of the Partnership's limited partner interests. Under a delegation of control agreement among us, the Partnership and its general partner, Enbridge Energy Company, Inc., referred to as the General Partner, we manage the Partnership's business and affairs. The General Partner is an indirect, wholly-owned subsidiary of Enbridge Inc., an energy company based in Calgary, Alberta, Canada that we refer to herein as Enbridge. We have prepared the accompanying unaudited interim financial statements in accordance with accounting principles generally accepted in the United States of America for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements. In the opinion of management, they contain all adjustments, consisting only of normal recurring adjustments, which management considers necessary to present fairly our financial position at March 31, 2015, our results of operations for the three-month periods ended March 31, 2015 and 2014 and our cash flows for the three-month periods ended March 31, 2015 and 2014. We derived our statements of financial position as of December 31, 2014 from the audited financial statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2014. Our results of operations for the three-month periods ended March 31, 2015 should not be taken as indicative of the results to be expected for the full year. The unaudited interim financial statements should be read in conjunction with our financial statements and notes thereto presented in our Annual Report on Form 10-K for the fiscal year ended December 31, 2014. Our results of operations, financial position and cash flows are dependent on the results of operations, financial position and cash flows of the Partnership. As a result, you should also read these unaudited interim financial statements in conjunction with the Partnership's audited consolidated financial statements and notes thereto presented in its Annual Report on Form 10-K for the fiscal year ended December 31, 2014, as well as the Partnership's unaudited interim consolidated financial statements presented in its Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2015.
	Partnership Incentive and Other Distributions
	The General Partner receives distributions through a wholly-owned subsidiary's ownership of Incentive Distribution Units, or IDUs, on the portion of cash distributions that exceed certain target thresholds on a per unit basis under the Partnership's partnership agreement, or the Partnership Agreement. The IDUs entitle the holder thereof to receive 23% of the incremental cash distributions paid by the Partnership in excess of $0.5435 per unit per quarter on its Class A and Class B common units, collectively, the common units, the i-units we own, the Class D Units, and the Class E Units.
	In addition, the General Partner receives distributions from the Partnership through its ownership of Preferred Units, Class D units, and Class E units. The Preferred Units are entitled to annual distributions of 7.50% of the issue price, payable quarterly. Class D and Class E units entitle the holders thereof to receive quarterly distributions equity to the amount derived by multiplying the number of Class D and Class E units outstanding by the distribution rate on the Partnership's common units and i-units.
	The effect of distributions to holders of the IDUs, Preferred Units, Class D units, and Class E units are divided among the Partnership's remaining limited partners: (1) Class A common units, (2) Class B common units, and (3) i-units based on our ownership interest in the Partnership. Thus, our “Equity income (loss) from the investment in Enbridge Energy Partners, L.P.” on our statements of income includes our pro-rata share of these costs every quarter.
	The Partnership Agreement does not permit capital deficits to accumulate in the capital account of any limited partner and thus requires that such capital account deficits brought to zero, or “cured,” by additional allocations from the positive capital accounts of the common units, i-units, and General Partner, generally on a pro-rata basis. Our equity income from the Partnership is adjusted for our pro-rata share of such reallocations. For the three-month period ended March 31, 2015, our equity earnings were reduced by $0.5 million, for our pro-rata share of the allocation needed to cure the capital account deficit of the Class B common units.

SHAREHOLDERS' EQUITY [Abstract]
SHAREHOLDERS' EQUITY	2. SHAREHOLDERS' EQUITY
	The Partnership records an adjustment to the carrying value of its book capital accounts for certain changes to its equity structure. We refer to these adjustments as capital account adjustments. We recognize any capital account adjustments recorded by the Partnership to the book capital account it maintains for our i-units by increasing or decreasing our investment in the Partnership and recording a corresponding capital account adjustment directly to “Shareholders' equity” on our statements of financial position.
	The following table presents significant changes in Shareholders' equity during the three-month period ended March 31, 2015 and 2014.
				For the three months ended March 31,

	The following table sets forth the details regarding our share distributions, as approved by our board of directors, for the three-month period ended March 31, 2015:
							Distribution				Average				Listed		Shares

	Distribution			Distribution			of the				Price of the		i-units		Distributed		to General

	We had non-cash operating activities in the form of i-units distributed to us by the Partnership and corresponding non-cash financing activities in the form of share distributions to our shareholders in the amounts of $38.9 million and $34.7 million during the three-month periods ended March 31, 2015 and 2014, respectively.
	Alberta Clipper Drop Down to the Partnership
	On January 2, 2015, the Partnership completed a transaction, or the Drop Down, pursuant to which it acquired the remaining 66.7% interest in the U.S. segment of the Alberta Clipper Pipeline from its General Partner. The consideration consisted of approximately 18,114,975 units of a new class of limited partner interests designated as Class E units issued to the General Partner, plus a cash repayment of approximately $306.0 million of indebtedness. The Class E units were issued at a notional value of $38.31 per unit, which was determined based on the trailing five-day volume-weighted average of the Partnership's Class A common units as of December 31, 2014, which was the date on which the Partnership and the General Partner entered into a contribution agreement setting for the terms of the Drop Down.
	The Partnership recorded the issuance of the Class E units at a fair value of $767.7 million, which was $364.0 million higher than the $403.7 million carrying value of the Partnership's related noncontrolling interest in Alberta Clipper. As a result, the Partnership reduced the carrying values of the Class A and Class B common units, the i-units, and the General Partner interest by $364.0 million on a pro-rata basis. The recording of this noncash transaction reduced the book basis of our investment in the Partnership, based on our proportionate ownership interest in the Partnership at the time of the transaction, by $46.2 million, net of a $27.3 million tax benefit. A corresponding reduction to our Shareholders' equity was recorded and is reflected under “Capital account adjustments” in the significant changes in Shareholders' equity table above. The recording of this transaction also reduced the carrying values of both classes of the common units below zero.
	As discussed above, the Partnership Agreement requires that such capital account deficits are cured by additional allocations from the capital accounts of the i-units and General Partner on a pro-rata basis. Our pro-rata share of this curing was $29.4 million, net of a $17.3 million tax benefit, which is reflected as an additional reduction to the book basis of our investment in the Partnership. A corresponding reduction to our Shareholders' equity was recorded and is reflected under “Capital account adjustments” in the significant changes in Shareholders' equity table above.

INCOME TAXES [Abstract]
INCOME TAXES	3. INCOME TAXES
	Our long-term deferred income tax asset of $123.6 million and $73.7 million at March 31, 2015 and December 31, 2014, respectively, results from the deferred income tax expense associated with recording our equity in earnings of the Partnership, our share of the other comprehensive income of the Partnership and the impact of any equity restructuring of the Partnership. The terms of the i-units provide that the units owned by us will not be allocated income, gain, loss or deductions of the Partnership for tax purposes until such time that we dispose of our investment in the Partnership, thus resulting in the realization of the long-term deferred income tax asset or liability, respectively.
	We computed our income tax expense for the three-month period ended March 31, 2015 by applying a 38.3% effective income tax rate to our pre-tax income, which represents the federal statutory rate of 35.0% and the effective state income tax rate of 3.3%.  For the three-month period ended March 31, 2014, our income tax expense was computed by applying a 37.1% effective income tax rate to our pre-tax income, which represents the federal statutory rate of 35.0% and the effective state income tax rate of 2.1%.
	As a result of the Partnership's Drop Down and the issuance of Class E units, we recorded a $44.6 million deferred tax benefit. We believe that our net deferred tax asset will be realized through deferred tax expense on future equity earnings we receive from the Partnership.

	Share Distribution
	On April 30, 2015, our board of directors declared a share distribution payable on May 15, 2015, to shareholders of record as of May 8, 2015, based on the $0.57 per limited partner unit distribution declared by the Partnership. The Partnership's distribution increases the number of i-units we own. The amount of this increase is calculated by dividing the cash amount distributed by the Partnership per common unit by the average closing price of one of our Listed Shares on the New York Stock Exchange for the 10-day trading period immediately preceding the ex-dividend date for our shares, multiplied by the number of shares outstanding on the record date. We distribute additional Listed Shares to our shareholders and additional voting shares to the General Partner in respect of these additional i-units.
