Summary
Ameren Corporation (AEE) and its subsidiary Ameren Missouri have reached a stipulation and agreement with the Missouri Public Service Commission (MoPSC) staff and other intervenors regarding Ameren Missouri's electric service rate review. This agreement, filed on November 24, 2021, proposes a $220 million annual increase in Ameren Missouri's revenue requirement for electric service, a significant step towards resolving the rate case initiated in March 2021. The proposed settlement is based on a $10.2 billion rate base and a common equity ratio of 51.97%. Key terms of the agreement include the continuation of mechanisms for fuel adjustment, pension and postretirement benefits, uncertain income tax positions, excess deferred income taxes, and renewable energy standard costs. Importantly, the agreement also provides for the recovery of $61 million in remaining non-labor operating costs and related returns associated with the Meramec Energy Center, which is slated for retirement in 2022, to be recovered over five years. The proposed effective date for the new rates is February 28, 2022, though the MoPSC's final approval is pending, and the outcome of any potential rehearing or appeal remains uncertain.
