One year from the date your deposit is paid in full, it may be refunded with interest, if all of the following conditions are met:
- The service was not disconnected for nonpayment
- No more than two late payments
- The account is not past due at the time of review
- No returned checks for non-sufficient funds
If your account does not meet these conditions, it is reviewed annually and the deposit is retained until the above criteria are met. The current interest rate is 0.12% for the year 2022, according to the Maryland Public Service Commission.
