They shall have the power to control, regulate and order such changes, improvements, extensions, additional facilities, appliances or equipment in or upon the plant and property of any person or corporation operating public utilities within the City as may be deemed necessary to promote the public interest, convenience or safety, and to protect its employees in the construction, maintenance or operation of any such public utilities.
Every charge, rate, fare or compensation made, charged or demanded by any person or corporation engaged in the operation of a public utility within the City of Portland for any service rendered or to be rendered shall be just, fair and reasonable.
