The Public Service Commission is using new legislation to possibly alter your electric bills. Under a bill passed by the General Assembly, the PSC has 90 days in which they can order certain electrical corporations to make adjustments to their rates. It’s a reactionary measure to the recent changes in the federal tax code. The PSC has filed notice that they are opening a case to adjust Ameren Missouri’s rates. Applications to intervene in the case must be received no later than June 13th.
