(a) Any customer receiving service from any electric supplier, which is not subject to the Public Utilities Act, who contends that he is not receiving adequate service from that supplier, or who contends that he is being discriminated against by that supplier, may complain to the Commission. If the Commission on hearing finds that the service is inadequate and that there is another supplier whose service would be adequate and who is willing to serve that customer, the customer shall be released to such other supplier unless the supplier against whom complaint is made makes its service to that customer adequate within a reasonable time to be fixed by the Commission. If there is no such other supplier the Commission may direct that service be made adequate. If the Commission finds on hearing that such customer is being discriminated against as compared with other customers of the electric supplier so supplying such customer, the Commission shall order such supplier to cease and desist from such discrimination.(b) If any electric supplier, which is not subject to the Public Utilities Act, refuses to serve a customer whom it is obligated to serve and who has applied for service to the supplier in accordance with the supplier's standard rules as to service, the Commission, on receiving a complaint from the customer and after a hearing thereon, may direct the supplier to serve that customer.
