Maryville has joined a growing number of communities, among them Glen Carbon, in making the switch to the non-regulated arm of Ameren Corporation’s energy operations, represented by Ameren Energy Marketing.
The change was approved by trustees at Wednesday’s board meeting and will go into effect this March.
AEM markets power through annual contracts on a non-regulated, fixed-rate basis in contrast to the regulated, variable market rates used by Ameren Electric. It sells power on a wholesale-like basis directly to municipalities, other utilities, financial institutions and business customers which it produced through 11 generating facilities in Illinois and Missouri.
At the time Glen Carbon switched to AEM last September, it was estimated that it would save the village approximately $22,000 per year in electricity costs.
Maryville officials, who agreed to a three-year contract, have estimated savings of up to $50,000 over that three-year period. The change will not pertain to Maryville customers of Southwestern Electric Cooperative.
