DR 98-058 WILTON TELEPHONE COMPANY Overearnings Investigation Order Approving Temporary Rates O R D E R N O. 22,968 June 30, 1998 APPEARANCES: Devine, Millimet & Branch by Frederick J. Coolbroth, Esq. for Wilton Telephone Company; the Office of the Consumer Advocate by William P. Homeyer for residential ratepayers, and E. Barclay Jackson, Esq. for the Staff of the New Hampshire Public Utilities Commission. I. PROCEDURAL HISTORY Pursuant to New Hampshire Public Utilities Commission (Commission) Order No. 22,823 in DR 97-187, the Staff of the Commission (Staff) conducted and prepared for the Commission a review of the earnings of Wilton Telephone Company (Wilton) and the relationship of those earnings to Wilton's toll rates. On April 20, 1998, the Commission issued an Order of Notice opening this docket. The Order of Notice scheduled a prehearing conference for May 27, 1998, to consider motions to intervene, establish a procedural schedule and to address the issue of temporary rates. The Order of Notice required Wilton, Staff, and all parties to prefile testimony on the issue of temporary rates by May 20, 1998. By motion filed April 29, 1998, the Office of the Consumer Advocate (OCA) requested that the Commission amend the schedule for filing testimony on temporary rates or, in the alternative, permit the OCA to file rebuttal testimony on that issue after the May 27 prehearing conference. Wilton objected to the OCA's motion on procedural grounds. By letter dated May 18, 1998, the Commission granted the OCA's request to file rebuttal testimony and rescheduled the date for hearing evidence on the issue of temporary rates to June 19, 1998. Staff and Wilton filed testimony on temporary rates on May 22, 1998. After discussions, Staff and Wilton reached agreement regarding the level of temporary rates. The OCA concurred in the agreement. After the duly noticed prehearing conference on May 27, 1998, the Commission issued an order approving a procedural schedule for the permanent rate case, Order No. 22,960. At the hearing on temporary rates on June 19, 1998, the parties and Staff presented a Stipulation solely with regard to the issue of temporary rates in this docket. II. POSITIONS OF THE PARTIES AND STAFF Staff and the parties agreed that Wilton's existing retail rates should go into effect as temporary rates as of the date of issuance of this order. The effect of temporary rates is to permit reconciliation of any overearnings or underearnings by the company, pursuant to RSA 378:27, retroactive to the date of this order. III. COMMISSION ANALYSIS Our authority to set temporary rates is explicitly authorized by RSA 328:27, conditioned on a finding that such rates are in the public interest. Temporary rates are established without the extensive investigation as is required for the determination of permanent rates. Re New England Telephone & Telegraph Company v. State, 95 N.H. 515 (1949); Pennichuck Water Works, Inc., 78 NH PUC 197 (1993). The standard for determining temporary and permanent rates requires that rates must be sufficient to yield not less than a reasonable return on the cost of utility property that is used and useful in the public service less accrued depreciation. RSA 378:38, Pennichuck, 78 NHPUC 197, 200. In the instant case the parties and Staff propose temporary rates at current levels. We approved Wilton's rates in Docket DF 94-021 (June 6, 1994 ). We find that the proposed temporary rates are consistent with the public interest and sufficient to yield a reasonable return on the cost of Wilton's property. Staff will be conducting an audit of Wilton, which will provide the information needed to determine the company's permanent rate level. Based upon the foregoing, it is hereby ORDERED, that temporary rates for Wilton shall be set at current levels. By order of the Public Utilities Commission of New Hampshire this thirtieth day of June, 1998. Douglas L. Patch Bruce B. Ellsworth Susan S.
