The utility shall keep copies of its schedules open to public inspection under such rules as the commission prescribes.

(2) No utility shall charge, demand, collect, or receive from any person a greater or less compensation for any service rendered or to be rendered than that prescribed in its filed schedules, and no person shall receive any service from any utility for a compensation greater or less than that prescribed in such schedules.

(3) The provisions of this section do not require disclosure or publication of a provision of a special contract that contains rates and conditions of service not filed in a utility's general schedule if such provision would otherwise be entitled to be excluded from the application of KRS 61.870 to 61.884 under the provisions of KRS 61.878(1)(c)1.
