If a public utility, as defined in N.J.S.A. 48:2-13, is aggrieved by the action of a municipal board through said agency's exercise of its powers under this act, with respect to any action in which the public utility has an interest, an appeal to the Board of Public Utility Commissioners of the State of New Jersey may be taken within 35 days after such action without appeal to the municipal governing body pursuant to N.J.S.A. 40:55D-17 unless such public utility so chooses. In such case appeal to the Public Utility Commissioners may be taken within 35 days after action by the governing body. A hearing on the appeal of a public utility to the Public Utility Commissioners shall be had on notice to the agency from which the appeal is taken and to all parties primarily concerned, all of whom shall be afforded an opportunity to be heard. If, after such hearing, the Board of Public Utility Commissioners shall find that the present or proposed use by the public utility of the land described in the petition is necessary for the service, convenience or welfare of the public, the public utility may proceed in accordance with such decision of the Board of Public Utility Commissioners, any ordinance or regulation made under the authority of this act notwithstanding.
