(a) In case of failure to agree upon the joint use or interconnection of facilities or the conditions or compensation for joint use or interconnections, the public utility, including any municipality, or an interested person may apply to the commission for an order requiring the interconnection. If, after investigation and opportunity for hearing, the commission finds that public convenience and necessity require the joint use or connection, and that the use or connection will not result in substantial injury to the owner utility or its customers, or in substantial detriment to the services furnished by the owner utility, or in the creation of safety hazards, it shall

1. (1) order that the use be permitted;
2. (2) prescribe reasonable conditions and compensation for the joint use;
3. (3) order the interconnection to be made;
4. (4) determine the time and manner of the interconnection;
5. (5) determine the apportionment of costs and responsibility for operation and maintenance of the interconnection.
