AQUILA AND BLACK HILLS CORPORATION FILE

FOR ANTITRUST CLEARANCE ON PROPOSED TRANSACTION

KANSAS CITY, MO, Aug. 3, 2007 – Aquila, Inc. (NYSE: ILA) and Black Hills Corporation (NYSE: BHC) today announced that they have filed notifications for antitrust clearance under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended. These filings relate to the previously announced agreement for Black Hills to acquire Aquila electric generating and distribution properties in Colorado and its natural gas distribution properties in Colorado, Iowa, Kansas and Nebraska.

The companies anticipate that the 30-day initial waiting period applicable to the proposed transaction under Hart-Scott-Rodino will expire at 11:59 p.m. on September 4, 2007, unless this period is terminated earlier or extended. The filing of Hart-Scott-Rodino notifications and the expiration of the applicable waiting period is required for each party to close the proposed transaction.

In April 2007, Aquila and Black Hills filed the requisite state regulatory applications regarding the proposed transaction, including regulatory applications in Colorado, Iowa, Kansas and Nebraska. With today’s filing of the Hart-Scott-Rodino notifications, the companies have now filed applications for all state and federal regulatory approvals and reviews required for the proposed acquisition.
