(1) A regulated electric distribution utility may not disconnect or deny electric distribution service to a customer due to the customer's failure to pay for unregulated service or service provided by another entity. A regulated natural gas distribution utility may not shut off or deny regulated natural gas distribution service to a customer due to the customer's failure to pay for unregulated service or service provided by another entity. When the same regulated utility is both a customer's natural gas distribution utility and electric distribution utility, it may not deny, disconnect or shut off natural gas service or electric service due to the customer's failure to pay for the other utility service.

(2) Regulated distribution utilities may offer agreements to landlord small customers to allow them to authorize the utility to switch a rental unit's electricity and/or natural gas service to the default supplier or to a specified competitive supplier in the event of a tenant customer's service termination.
