Enbridge Energy Partners Reports 2012 Earnings and Announces 2013 Financial Guidance

HOUSTON, TX—February 13, 2013—Enbridge Energy Partners, L.P.’s (NYSE:EEP) (“Enbridge Partners” or “the Partnership”) key financial results for the fourth quarter of 2012, compared to the same period in 2011, were as follows:

Adjusted net income for the three and twelve month periods ended December 31, 2012, reported above, eliminates the impact of: (a) additional environmental costs, net of insurance recoveries, associated with the incidents on Lines 14 and 6B; and (b) non-cash, mark-to-market net gains and losses; among other adjustments. Refer to the Non-GAAP Reconciliations table below for additional details.

Adjusted net income of $87.2 million for the fourth quarter of 2012 was $29.2 million lower than the same period from the prior year primarily due to lower natural gas liquids (“NGL”) prices and increased operating and administrative expenses.

“Adjusted earnings for 2012 are not reflective of our expectations primarily as a result of weak natural gas and NGL prices that impacted our performance. While we believe natural gas and NGL fundamentals will gradually improve, we remain focused on our objective of delivering sustainable and prudent growth to our unitholders,” said Mark Maki, President of the Partnership. “Above all else, Enbridge and the Partnership are committed to achieving industry leadership in the areas of safety and integrity and we continue to make the operating and capital investments necessary to achieve this objective,” added Maki.

“The long-term outlook for the Partnership remains strong. Our $8.5 billion secured growth program is proceeding on schedule and will progressively transform the Partnership towards an even lower risk business model as the cash flows are secured predominantly by long-term, low-risk commercial frameworks such as cost-of-service or demand-based contract structures. The Partnership’s distributable cash flow growth will begin to accelerate once these accretive growth projects enter service, which will solidify our long-term distribution growth outlook of 2 to 5 percent annually. We expect business fundamentals will continue to improve later in 2013. As a result, we estimate the Partnership’s EBITDA for 2013 will increase in excess of 10% and will be between $1,250 million and $1,350 million,” noted 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 December 31, 2012 with the same period of 2011. The comparison refers to adjusted operating income, which excludes the effect of non-cash and nonrecurring items (see Non-GAAP Reconciliations section below).

Liquids – For the three month period ended December 31, 2012, adjusted operating income for the Liquids segment decreased $28.5 million from $161.5 million for December 31, 2011 to $133.0 million. Higher revenues from an increase in index transportation rates, in addition to higher storage revenues from the Partnership’s Cushing storage facilities, were more than offset by lower volumes on our liquids pipeline systems and higher operating and administrative expenses. The increase in operating and administrative expenses was attributable to higher pipeline integrity costs, higher depreciation expense related to assets placed into service and an increase in workforce related costs. Additionally, fourth quarter 2012 results reflected approximately $9 million of costs to complete remediation of crude oil releases, primarily around our terminals.

2

Natural Gas – Adjusted operating income for the Natural Gas segment was $42.9 million for the three month period ended December 31, 2012, which was $8.5 million lower than the same period in 2011. Fourth quarter 2012 adjusted operating income was impacted by lower revenues due to lower natural gas and natural gas liquids prices, lower volumes on our East Texas system and higher operating and administrative expenses.

Marketing – The Marketing segment reported an adjusted operating loss of $1.4 million for the three month period ended December 31, 2012, an increase of $0.2 million from the $1.2 million of adjusted operating loss for the same period of 2011. The gas marketing business continues to be impacted by a weak natural gas pricing environment and narrow locational basis differentials.

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.

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 in the United States.
