The Illinois Commerce Commission has ordered Ameren to cut its electric delivery rate by nearly $50 million.
That decision was approved by commission by a vote of 3 to 2 on Wednesday.
Ameren had initially proposed a reduction of $19.3 million from its current revenue from delivery service rates. The ICC is ordering the utility company to cut the rate by $48.1 million.
Ameren spokesman Leigh Morris said the utility company is disappointed by the decision and that the commission is not following the law.
The delivery rate decrease from the commission's decision applies to rates from October through December of this year. Morris said another decision by the commission, which is expected in December, will determine the new delivery rates beginning in January.
