and justice of rates and charges for the service rendered by public utilities or railroads,

or for any other purpose authorized by law, may investigate and ascertain the value

public utility is situated in such municipal corporation. (B) To assist the commission in preparing such a valuation, every public utility or railroad

shall: (1) Furnish to the commission, or to its agents, as the commission requires, maps, profiles,

schedules of rates and tariffs, contracts, reports of engineers, and other documents,

records, and papers, or copies of any of them, in aid of any investigation and ascertainment

of the value of its property; (2) Grant to the commission or its agents free access to all of its premises and property

and its accounts, records, and memoranda whenever and wherever requested by any such

authorized agent; (3) Cooperate with and aid the commission and its agents in the work of the valuation

of its property in such further particulars and to such extent as the commission requires

and directs. (C) The commission may make all rules which seem necessary to ascertain the value of

the property and plant of each public utility or railroad.
