State utility regulators plan on Thursday to release their solution to concerns about American Electric Power rates, while statewide groups representing farmers, school boards and churches have become the latest to file complaints. Since the beginning of the year, the Public Utilities Commission of Ohio has received 1,018 complaints about the AEP rates; 410 of the them are about business rates. This includes letters sent in the last few days from the Ohio Farm Bureau Federation, the Ohio School Boards Association and the Catholic Conference of Ohio.
