OKLAHOMA CITY (AP) - A hearing is underway on a proposed rate increase by the state's largest electric utility that could result in a more than $6 per month increase in the average household customer's utility bill.

The multi-day hearing began Tuesday before an administrative law judge with the Oklahoma Corporation Commission.

Oklahoma Gas and Electric is asking to raise its rates by about $73 million - which would increase the average home electric bill by $6.60 per month.

The Corporation Commission's Public Utility Division is recommending a rate decrease of about $4 million.

Attorneys for both sides and other interested parties will provide testimony, submit evidence and question witnesses before the judge.

The judge will issue a report and recommendations. The three-member Commission is expected to vote on the proposal early next year.
