Alaska Commission Establishes Rate Review Procedures for SEMCO'S ENSTAR Unit

PORT HURON, Mich., Nov. 29 /PRNewswire/ -- SEMCO ENERGY (NYSE: SEN) reported today that The Regulatory Commission of Alaska has issued an order finding that the studies filed in April of this year by SEMCO's ENSTAR Natural Gas Division and its Alaska Pipeline Company affiliate generally complied with applicable statutory and legal requirements. SEMCO acquired ENSTAR in November 1999, and had been required to file revenue requirement and cost of service studies by the Commission in its order approving the acquisition.

Noting that ENSTAR's rates had not been reviewed since 1986, the Commission also determined that further examination of ENSTAR's revenue requirements and cost of service studies is required to ensure that ENSTAR's rates are just and reasonable. In its order the Commission stated that, if changes in ENSTAR's existing rates are determined to be appropriate, such changes would be applied on a prospective basis.

William L. Johnson, Chairman, President and Chief Executive Officer of SEMCO ENERGY, Inc., stated, "We welcome the opportunity to work with the Commission, respond to its questions and demonstrate that ENSTAR's rates are fair to its customers and the Company's shareholders. In fact, ENSTAR's rates currently are among the lowest in the country."

A pre-hearing conference to establish a procedural schedule and to address disposition of the issues has been set for February 8, 2001.
