The Empire District Electric Company Announces New Missouri Electric Rates

The Empire District Electric Company (NYSE:EDE) today announced that the Missouri Public Service Commission (MPSC) has issued an Order in the rate case filed by the Company on October 1, 2007. The Company had asked for an annual increase in revenues of approximately $34.7 million or 10.11 percent.

The Order results in a net increase in revenue of approximately $22.0 million, or 6.7 percent, and is based on a 10.8 percent return on equity. We anticipate the rates will go into effect by September 1, 2008.

With this case, the MPSC authorized a fuel adjustment for Empire's Missouri customers. The MPSC established a base rate for the recovery of fuel and purchased power expenses used to supply energy. Going forward, the fuel adjustment will be modified twice a year with Commission approval. If the fuel expense is less than the base, customers will see a credit. If the fuel expense is higher, customers will see an additional charge. This will be listed as a separate item and allows customers a more immediate view of what impact fuel expenses are having on their bill.

The Order contains two components. The first component provides an addition to base rates, which the Commission has reported is approximately $27.7 million. The second component is an amortization that provides Empire additional cash through rates during the current construction cycle. This construction, which is a part of the Company's long-range plan to ensure reliability, includes the facilities at the Riverton Power Plant and Iatan 2 Power Plant, as well as environmental improvements at the Asbury Power Plant and at Iatan 1. The second component related to regulatory amortization has been adjusted downward by $5.7 million. The regulatory amortization is now approximately $4.5 million.

The Commission also approved the Stipulation and Agreements providing for the recovery of deferred expenses for the 2007 ice storms and continuation of the pension and other post-retirement employee benefits trackers. The Commission also approved incorporation of the Staff's base fuel and purchased power figure of approximately $32.50 per megawatt hour, and established a two-way tracker for the cost of compliance with the vegetation and infrastructure reliability rules. The new rates will allow recovery of the capital additions for the 150-megawatt generating unit at the Riverton Power Plant, the selective catalytic reduction system at the Asbury Power Plant, and the 2007 ice storms.

For a residential customer using 1,000 kilowatt-hours monthly, the impact of the new base rates will be about $6.13 per month.
