EXHIBIT 99.1 [NORTHERN BORDER PARTNERS, L.P. LETTERHEAD] NORTHERN BORDER PARTNERS REPORTS SECOND QUARTER RESULTS FOR IMMEDIATE RELEASE: Thursday, July 24, 2003 OMAHA - Northern Border Partners, L.P. (NYSE - NBP) reports second quarter 2003 net income of $32.1 million or $0.66 per unit compared to $30.1 million or $0.67 per unit in the second quarter 2002. Year-to-date net income for 2003 was $64.7 million or $1.35 per unit as compared to the first six months of 2002 net income of $58.1 million or $1.28 per unit. Earnings before interest, taxes, depreciation and amortization (EBITDA) increased from $83.1 million in the second quarter of 2002 to $85.3 million in the second quarter 2003. Year-to-date 2003 EBITDA was $172.1 million compared to $162.1 million for the same period one year ago. Year-to-date 2003 net income reflects a charge of approximately $600,000 or $0.01 per unit for the cumulative effect of the Partnership's required implementation of Statement of Financial Accounting Standards (SFAS) No. 143 "Accounting for Asset Retirement Obligations". SFAS No. 143 requires entities to record on a present value basis a liability for asset retirement obligations, if the liability can be reasonably estimated. Results for the quarter include an after-tax gain of $4.9 million, or $0.10 per unit, reported in Discontinued Operations. The gain relates to the June sale of the Gladys and Mazeppa processing plants located in Alberta, Canada for $40.0 million. The average units outstanding for the quarter increased by 3.3 million units compared to the same period in 2002. Since the beginning of the year, Northern Border Partners has issued approximately $102 million of new equity to fund recent acquisitions and position the company for future growth. Delivered volumes for the Partnership's interstate natural gas pipelines segment increased during second quarter 2003 to 276 billion cubic feet (Bcf) from 231 Bcf for the second quarter of 2002 primarily due to the acquisition of Viking Gas Transmission early this year. Total gathering volumes increased to 1,111 million cubic feet per day (MMcf/d) during the second quarter 2003 compared to 1,047 MMcf/d for the second quarter 2002. However, volumes on the Partnership's wholly-owned gathering systems in the Powder River Basin decreased from 244 MMcf/d in second quarter 2002 to 212 MMcf/d in the second quarter 2003. Processing volumes from the Partnership's continuing operations were 52 MMcf/d for the second quarter of 2003 compared to 56 MMcf/d for the second quarter 2002. "Entering 2003, Northern Border Partners focused on two challenges. The first, the recontracting effort on Northern Border Pipeline, has been successfully completed. The second is the drilling activity in the Powder River Basin, which has not escalated as we had anticipated. Though the Environmental Impact Statement has been issued drilling permits continue to lag," said Bill Cordes, chairman and chief executive officer of Northern Border Partners. "We continue to believe that the Powder River Basin is a critical supply source and that its further development will be necessary to meet the energy needs of the United States." The Partnership indicated that for the full year 2003, with the inclusion of the second quarter gain, it expects earnings per unit toward the high end of the previously announced range of $2.55 to $2.65 per unit. On July 21, 2003, the Partnership Policy Committee declared the Partnership's quarterly cash distribution of $0.80 per unit for the second quarter of 2003. The indicated annual rate is $3.20. The distribution is payable August 14, 2003 to unitholders of record July 31, 2003. Northern Border Partners will host a conference call to review second quarter 2003 results on Friday, July 25, at 11:00 a.m. Eastern time. Interested parties may listen via the Internet live or on a replay basis through the Partnership's website at http://www.northernborderpartners.com. A replay of the call will be available through August 1, 2003 by dialing, toll free in the United States and Canada, 800-405-2236 and entering passcode 544419. The call will also be archived through October 15, 2003 on Northern Border Partners' website. The Partnership has disclosed EBITDA amounts in this press release. These amounts are non-GAAP financial measures. Management believes EBITDA provides useful information to investors as a measure of comparability to peer companies. However, EBITDA calculations may vary slightly from company to company, so the Partnership's computation of EBITDA may not be comparable to other companies. Management further uses EBITDA to compare the financial performance of its segments and to internally manage those business segments. A reconciliation of EBITDA to our net income and cash flows from operating activities is included in the financial information included in this release. For segment information of this press release, EBITDA is reconciled to net income rather than to cash flows from operating activities, since the Partnership does not determine segment cash flows from operating activities due to its inter-company cash management activity. Northern Border Partners, L.P. owns a 70 percent general partner interest in Northern Border Pipeline Company. Additionally, the Partnership owns Midwestern Gas Transmission Company; Viking Gas Transmission Company; a one-third interest in Guardian Pipeline, L.L.C.; has gathering systems and processing plants in the Powder River, Wind River and Williston Basins in the United States; has an interest in a gathering system in central Alberta, Canada; and transports coal-water slurry via a pipeline in the southwestern U.S. Northern Border Partners, L.P. information may be found at http://www.northernborderpartners.com. This press release includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Although Northern Border Partners, L.P. believes that its expectations are based on reasonable assumptions, it can give no assurance that such expectations will be achieved. Important factors that could cause actual results to differ materially from those in the forward-looking statements include natural gas development in the Powder River, Wind River, Williston and Western Canadian Sedimentary Basins; regulatory actions and receipt of expected regulatory clearances; competitive conditions in the overall natural gas and electricity markets; our ability to market pipeline capacity on favorable terms; performance of contractual obligations by the shippers; prices of natural gas and natural gas liquids; developments in the voluntary petition for bankruptcy including Enron's announced intention to form CrossCountry Energy, of which Northern Plains and Pan Border would be a part; potential regulation under Public Utilities Holding Company Act; and conditions in the capital markets and our ability to access the capital markets. #### NORTHERN BORDER PARTNERS, L.P.
