Missouri Public Service Commission v. Union Electric Co.

The Supreme Court vacated the decision of the Missouri Public Service Commission determining that the term “methodology” as used in Rule 20.093(1)(F) means not only the formula used to compute a sum (i.e., the variables to be used) but also the values of those variables.Staff of the Commission filed a complaint alleging that Union Electric Co. (Ameren) violated a rule of the Commission when it failed to use certain 2014 data to calculate Ameren’s net shared benefits under an energy-efficiency plan approved by the Commission in 2012. The Commission granted Staff’s motion for summary determination. Ameren appealed. The Supreme Court vacated the decision of the Commission, holding because the Commission’s erroneous determination of the meaning of term “methodology” played a central role in its decision, the matter must be remanded to the Commission for further proceedings.
