Idaho Underground Water Users Association

Idaho Power Company (the Company) in January, 1962, instituted these proceedings by filing with Idaho Public Utilities Commission (the Commission), its request for 13.6% increase in its rates charged its general users. Various protests, including that of Idaho Underground Water Users Association (the appellant), were filed against the granting of any rate increase. Hearings were conducted and, after the introduction of voluminous testimony and admission of many exhibits, the Commission entered Order No. 6647, denying the Company's proposed tariff and schedule of charges which would have constituted a 13.6% increase in the rates, but directed the Company to submit a revised tariff for an increase of rates of 7.5%. The new tariff was filed and approved by the Commissioner's Order 6659, and on the same day appellant filed its motion for rehearing, directed towards Order No. 6647, asserting it to be erroneous and contrary to the evidence. This petition for rehearing was denied by Order No. 6680. Appellant appealed from these various orders of the Commission, the effect of which was to grant to the Company a 7.5% increase in the rates charged various of its customers. Appellant is an unincorporated association, the membership of which is comprised of approximately 5100 users of the electrical power supplied by the Company. The members use the electrical power for the purpose of irrigation and soil drainage pumping, as well as general service and residential usages.
