ScottishPower announces that on 4 August 2004 its subsidiary, PacifiCorp, filed a general rate case request with the Utah Public Service Commission for approximately $111 million related to capital investments and increases in operating costs, including fuel, purchased power, and other business costs.

The filing requests recovery of capital investments in generation, transmission and distribution networks, which support Utah's fast-growing electricity demand. The company is asking for use of a future test year and an allowed rate of return on equity of 11.125%, in line with recent requests in other states.

The rate case is expected to be resolved in April 2005.
