Frequently Asked Questions
The main development is the Mississippi Public Service Commission's (PSC) issuance of an order that adopts a stipulation for the rate recovery of costs associated with the in-service assets of Mississippi Power's Kemper Integrated Gasification Combined Cycle (IGCC) facility. This order establishes permanent annual retail rate recovery of approximately $126 million.
The 'prudence finding' means that the Mississippi PSC has determined that the costs included in the stipulated revenue requirement for the in-service Kemper IGCC assets were incurred prudently. This is a significant positive for investors as it validates a portion of the project's costs for recovery through customer rates.
The new permanent rates will result in an annual revenue of approximately $126 million for Mississippi Power. Upon implementation of these permanent rates, the interim rates that were previously collected will be terminated. Mississippi Power will then issue credits to customer bills within 90 days for the difference between the interim rates collected and the newly established permanent rates.
No, not all costs are definitively approved for rate recovery through this order. The order primarily addresses the in-service assets and provides for a specific annual revenue requirement. Any costs excluded, reduced, or compromised in this revenue requirement calculation will be deferred as regulatory assets and will be addressed in a future prudency hearing or a rate case expected after the entire Kemper IGCC project is commercially operational.
