Enbridge Energy Partners Declares Distribution and Reports Earnings for Second Quarter 2013

HOUSTON, TX—July 29, 2013 - Enbridge Energy Partners, L.P. (NYSE:EEP) (“Enbridge Partners” or “the Partnership”) today declared a cash distribution of $0.5435 per unit payable August 14, 2013 to unitholders of record on August 7, 2013.

The Partnership’s key financial results for the second quarter of 2013, compared to the same period in 2012, were as follows:

Adjusted net income for the three and six month periods ended June 30, 2013, as reported above, eliminates the impact of: (a) additional environmental costs, net of insurance recoveries, associated with the Line 6B incident; and (b) non-cash, mark-to-market net gains and losses; among other adjustments. Refer to the Non-GAAP Reconciliations section below for additional details.

Adjusted net income of $74.7 million for the second quarter of 2013 was $22.1 million lower than the same period from the prior year primarily due to the impact of lower natural gas liquids (“NGL”) prices in our natural gas business and the inclusion of the deferred distribution from the recently issued $1.2 billion of preferred units as a decrease in net income available to the general and limited partners.

“Lower than forecasted deliveries on our liquids pipelines systems due to significant unplanned downstream refinery maintenance, in addition to weak NGL prices and associated Midcontinent ethane rejection impacted our performance in the second quarter. Our results are not reflective of our expectations and we expect our performance to strengthen during the second half of the year. Deliveries on our liquids pipelines systems are expected to increase as we begin realizing the benefits of major capital projects which enter service and begin delivering earnings and cash flows,” said Mark Maki, president of the Partnership.

“The management team is very focused on delivering our investment proposition elements: stability, growth, income and low risk business model. The long-term outlook for the Partnership remains strong as our multi-billion organic growth program will deliver long-term, low risk growth to our unitholders. Project construction is proceeding on schedule and we expect our distribution coverage

to improve as projects enter service and the Partnership’s distributable cash flow growth accelerates. During the quarter, we made solid strides executing on our financing initiatives. Collectively, the preferred unit private placement, exercising the option to put a portion of our Lakehead expansion projects and associated funding to our parent, in addition to the accounts receivable securitization bolsters our financing flexibility to smooth our funding activities over a longer period of time. These actions demonstrate the strong support by our sponsor, Enbridge Inc., which is a key distinguishing element of our investment proposition,” added Maki.

COMPARATIVE EARNINGS STATEMENT

COMPARISON OF QUARTERLY RESULTS

Following are explanations for significant changes in the Partnership’s financial results, comparing the three month period ended June 30, 2013 with the same period of 2012. The comparison refers to adjusted operating income, which excludes the effect of non-cash and nonrecurring items (see Non-GAAP Reconciliations section below).

Liquids –Second quarter adjusted operating income for the Liquids segment increased $12.4 million to $167.9 million from $155.5 million for the comparable period in 2012. Higher revenues from an increase in indexed transportation rates, in addition to higher tariff recoveries for integrity initiatives were partially offset by lower deliveries and remediation costs associated with a terminal leak at our Cushing storage facilities. Collectively, unplanned downstream refinery maintenance and outages on connecting pipelines impacted deliveries on our Lakehead and Midcontinent systems. In addition, competition from rail transportation as an alternative method of shipping crude oil to market due to transportation and market access constraints reduced deliveries on our North Dakota system.

Natural Gas – Second quarter adjusted operating income for the Natural Gas segment was $27.6 million lower than the same period of 2012. The decrease in adjusted operating income was primarily due to lower NGL prices, in addition to ethane rejection being experienced predominantly at our plants situated in the Midcontinent.

Marketing – Second quarter adjusted operating income for the Marketing segment was $2.5 million higher than the same period of 2012. Improved adjusted operating income resulted from the expiration of certain firm natural gas transportation demand fees on third party pipelines. Additionally, the improvement of natural gas prices led to additional opportunities to benefit from favorable price differentials between market centers.

Partnership Financing – In May 2013, Enbridge Partners issued 48,000,000 of its Series 1 Preferred Units to its General Partner in a private placement. The Series 1 Preferred Units represent limited partner interests in the Partnership, are convertible into the Partnership’s Class A common units and have a preferential 7.5 percent distribution right. The Partnership sold the Series 1 Preferred for aggregate proceeds of approximately $1.2 billion, which were used to repay commercial paper, to finance a portion of the Partnership’s capital expansion program relating to its core liquids and natural gas systems and for general partnership purposes.

During the second quarter the Partnership attributed approximately $13.1 million of earnings to the preferred unitholders. This amount is deducted from net income to arrive at the amount of net income attributable to the general and limited partners. Preferred distributions are accrued at an annual rate of 7.5 percent even though the payment of the distribution will be deferred until August 2015.

NON-GAAP RECONCILIATIONS

Adjusted net income and adjusted operating income for the principal business segments are provided to illustrate trends in income excluding derivative fair value losses and gains and other nonrecurring items that affect earnings. The derivative non-cash losses and gains result from marking to market certain financial derivatives used by the Partnership for hedging purposes that do not qualify for hedge accounting treatment in accordance with the authoritative accounting guidance as prescribed under generally accepted accounting principles in the United States.

Adjusted EBITDA (earnings before interest, taxes, depreciation and amortization) is used as a supplemental financial measurement to assess liquidity and the ability to generate cash sufficient to pay interest costs and make cash distributions to unitholders. The following reconciliation of net cash provided by operating activities to adjusted EBITDA is provided because EBITDA is not a financial measure recognized under generally accepted accounting principles.
