SEMCO acquired ENSTAR in 1999. The Order indicates an annual revenue reduction of $2.1 million, which would be 1.96 percent of ENSTAR's revenue in the normalized 2000 test year. The RCA has required ENSTAR to file an updated cost of service study and rate design by September 9, 2002, to reflect the results of the Order. In its Order, the RCA established a revenue requirement of $107.6 million and a 12.55 percent return on equity. The RCA said, "We established the 12.55 percent return on equity, which is at the upper end of the range proposed in the record, to reflect confidence in ENSTAR's management practices and to assure an incentive of capital investment in the company." SEMCO ENERGY Chief Financial Officer John E. Schneider said, "Although the Order issued by the RCA indicates an annual reduction in revenue, the outcome does not change our earnings guidance for 2002, which remains at $.80 to .85 per share."
