Papers unsealed in Ameren rate complaint

JEFFERSON CITY, Mo. -- State regulators have released a confidential report detailing how much money was earned by Ameren Missouri.

The Missouri Public Service Commission on Tuesday unsealed a November report that has been at the heart of a complaint alleging the utility was earning more than allowed.

The documents also include testimony from utility regulation consultants hired by Noranda Aluminum in New Madrid, Mo., which is challenging Ameren's electricity rates.

The consultants said Ameren's allowable earnings rate should be adjusted downward. If that adjustment were made, the consultants estimated Ameren earned $67 million more than what was reasonable.
