Exhibit 99
MDU Resources announces sale of domestic IPP companies
BISMARCK, N.D. - April 26, 2007 - MDU Resources Group, Inc. (NYSE:MDU) today announced that its subsidiary, Centennial Energy Resources LLC, has entered into a definitive purchase and sale agreement with Montana Acquisition Company LLC. (“Montana”), a new company formed by energy industry executive Paul Prager and Natural Gas Partners VIII, LP (“NGP”). Under the agreement, MDU will sell its domestic independent power production business unit consisting of Centennial Power, Inc. (“Centennial Power”) and Colorado Energy Management, LLC (“Colorado Energy Management”) to Montana.
The transaction is valued at $636 million, which includes the assumption of approximately $36 million of project-related debt. The closing of the sale is expected to occur in June and is subject to the receipt of regulatory approvals and fulfillment of other conditions established in the agreement. Proceeds from the sale will be used to fund MDU Resources’ acquisition of Cascade Natural Gas Corporation and will provide additional cash to deploy into growth opportunities that exist in its core lines of business.
Centennial Power’s generating assets include 603 MW of electric generating capacity located in Montana, Colorado, California and Georgia. The assets are fully contracted under mid- to long-term power purchase and sale agreements, and include coal-fired, natural gas-fired and wind-powered generation. Colorado Energy Management provides design, construction, operation and maintenance services to energy providers.
“We are very pleased with the agreement we have with Montana Acquisition Co.,” said Terry Hildestad, president and chief executive officer of MDU Resources. “Monetizing the value of these assets positions us to continue to create shareholder value while maintaining a strong balance sheet.”
“The success and substantial value created at Centennial Power and Colorado Energy Management is a tribute to those people that made it happen” said Paul Gatzemeier, president and chief executive officer of Centennial Energy Resources LLC.
Goldman, Sachs & Co. acted as financial advisor to MDU Resources in connection with the sale. Thelen Reid Brown Raysman & Steiner LLP was MDU’s legal counsel.
The information in this release includes forward-looking statements, including the expected closing of the sale and use of proceeds, as well as statements by the president and chief executive officer of MDU Resources and the president and chief executive officer of Centennial Energy Resources, within the meaning of Section 21E of the Securities Exchange Act of 1934. Although the company believes that its expectations are based on reasonable assumptions, actual results may differ materially.
