Yes! You can switch to a PrePay account even if you already have service with PUD 3.* Your existing deposit will be applied to your current account balance, with any remaining amount being applied as a credit to your PrePay account. If your account has a balance due when enrolling into PrePay, you can set up on a PrePay arrangement plan that will allow that balance to be paid off over time. When an account is in arrears when converting to PrePay, all future payments made are split 75/25 with 75% applied as payment toward future usage and 25% covering any owed balance.
*Some restrictions may apply.
