TALLAHASSEE, Fla.- The Florida Supreme Court is upholding a rate increase by the state's largest utility.
    
The court ruled Tuesday that the Public Service Commission didn't err when it reached a settlement with Florida Power & Light on a rate increase that could see bills increase by $9 a month for the average costumer.
    
The Office of Public Counsel contested the increase because the state-created consumer advocate didn't participate in the settlement discussions.
    
The rate increase was approved two years ago. FPL has roughly 4.6 million customers.
