FPL's billing and deposit practices are governed by the Florida Public Service Commission. To ensure fairness to all customers, some customers are required to secure their accounts with a deposit. FPL uses a credit scoring system to determine whether a deposit is required in order to open an account. This credit scoring system considers items on your credit report and/or prior credit history and produces a score.

Customers who are asked to pay a deposit are required to provide a deposit equal to two month's expected electric use when the home is occupied. For example, if you occupy your home year-round and use an average of $100 of electricity per month, the deposit amount would be $200. Your new residence's anticipated electric use is determined by the property's prior energy usage history, which is standard utility practice.
