Mississippi Public Service Commission Seeks Settlement Agreement for Southern's Kemper County IGCC Project
LCG, June 23, 2017--The Mississippi Public Service Commission (PSC) unanimously passed a motion on Wednesday instructing counsel to prepare an order pursuing potential solutions regarding the Kemper County Power Generation Facility. The order will be presented to the Commission at its July 6, 2017 meeting.
As part of the order, a new docket number will be opened encouraging a settlement to resolve some or all matters in question. The Commission would like a number of issues to be resolved by Southern Company subsidiary Mississippi Power, the Mississippi Public Utilities Staff and intervening parties. Specifically, the Commission would like the settlement to (i) remove risk from ratepayers for the lignite coal gasifier and related assets, (ii) avoid a rate increase to Mississippi Power Company customers, and (iii) modify the certificate issued to allow only for operation of a natural gas facility at the Kemper Project location.
The announcement issued by the PSC set tight schedule for the settlement process, which "shall be filed with the Commission no later than forty-five days from the effective date of the order." If a settlement is filed, a hearing will be set forty-five days from the date of the filing and a scheduling order entered.
A statement issued by Mississippi Power stated, "The PSC provided several guidelines to consider for the negotiations, including the possibility of the project only operating as a natural gas-fueled combined cycle plant. We expect the process for any negotiations and this new docket will be formally addressed as part of a proposed order the Commission will consider at their July 6 meeting."
The initial certificate was approved by the PSC on June 3, 2010. The 582-MW Kemper County project was designed, in a time of higher natural gas prices and anticipated greenhouse gas emission regulations, as an integrated gasification combined-cycle (IGCC) facility intended to showcase new technologies for gasifying coal, together with carbon capture capabilities to capture at least 65 percent of emissions. Like a traditional combined-cycle facility, the plant combines two combustion turbines with one steam turbine - three engines that turn generators to produce electric power. The project includes an adjacent lignite (a low-rank coal) mine.
The Kemper County project began operating in August 2014 fueled by natural gas, as the coal gasifiers were not ready to be placed into service. The project schedule has included a number of delays, including issues experienced with the ash removal system in one of the gasifiers and recent repairs of tube leaks and associated corrective actions in one of the project's syngas coolers. Project costs have also increased beyond initial expectations. The project costs through April were approximately $5.94 billion.
