Mississippi Power action encourages final settlement on Kemper

December 1, 2017

Gulfport, Miss. – Mississippi Power today announced it has reached a settlement agreement with the Mississippi Public Utilities Staff, Chevron, Chemours and Federal Executive Agencies on the remaining costs associated with the Kemper County energy facility. With the key parties in the Kemper settlement docket in agreement, today’s announcement represents final terms subject to the approval of the Public Service Commission.

“This agreement represents significant compromise from all parties involved, but is an important step to settle all costs remaining on the Kemper project,” said Mississippi Power President and CEO Anthony Wilson. “Putting the gasifier portion of Kemper that did not meet our expectations behind us is in the best interest of our customers, company and the state. We are pleased to continue operating an efficient natural gas facility at Kemper which has been serving our customers for more than three years.”

This agreement meets the directives issued by the Public Service Commission, including:

• The removal of risk to our customers for the gasifier and related assets.
• No customer rate increase related to Kemper.
• Operation of Kemper as a natural gas facility.

“If this stipulation is approved, we expect significant changes to our business,” said Wilson. “As we adjust to this considerable loss of revenue, our top priority will be to maintain safe and reliable service to our customers.”

The company currently expects a final order on Kemper from the Public Service Commission in January.
