Mississippi Power files alternative rate option, seeks interim rate relief
Action does not affect customer refunds

Gulfport, Miss. – Mississippi Power today filed a fourth Kemper-related rate option with the Mississippi Public Service Commission that would allow for cost recovery of portions of the Kemper project already operating and providing reliable electric service to customers.

In the wake of the PSC’s July 7 action to stop the collection of the Kemper-related rates, the company is asking the Commission to take immediate action to implement interim rates that reflect the new “In-Service Asset” option. The company is asking for a replacement of the 18-percent rate increase the Commission repealed based on the recent ruling by the Mississippi Supreme Court.

“As we have throughout this process, Mississippi Power remains committed to delivering the lowest-cost solution for the customers we are so privileged to serve,” said Mississippi Power President and CEO Ed Holland. “This filing will not affect the Kemper-related refunds customers are expected to receive per Commission requirement, and will not increase customer rates from their current level.”

The interim rates would be subject to refund, until the PSC can review the option, hold hearings and make a final decision on the rate plan. The new option outlines cost recovery of currently operating assets including the Kemper project’s combined cycle unit, electric transmission lines, water lines and storage pond, natural gas pipeline and regulatory assets. If approved, the interim rates would be effective with the first billing cycle of August which begins July 20, 2015.

The decision to make the new filing was based on several factors including the recent decisions by the PSC, the Mississippi Supreme Court, the decision by SMEPA to withdraw from the project, and lack of PSC approval of a permanent Kemper rate plan.

“Unfortunately, recent legal and regulatory decisions involving Kemper have greatly impacted and weakened the credit quality of Mississippi Power,” Holland said. “The longer we are without permanent rate recovery for the project, the more it jeopardizes the company’s ability to access the funds needed for continued business operations and for completion of Kemper. This new option will provide us with the minimum financial support we need to begin the process to improve the company’s financial strength.”
