The principal question raised by this appeal is whether the commission must file findings of fact which em-. brace the essentials upon which it bases the reasonableness of its rate order.
Sec.227.13, Stats.,provides:
“Every decision of an agency in a contested сase shall be in writing accompanied by findings of fact and conclusions of law. The findings of fact shall consist of a cоncise and separate state-' ment of the'ultimate conclusions upon each contested issue of faсt without recital of evidence.”
The commission contends that its statement of facts is concise and sufficient. In the оpinion filed by the commission with its order it stated:
“There will be a determination and finding of neither a rate base nor of a rаte of return for the purposes of this proceeding. That is not to say, however, that the rates herein prescribеd will be arrived at by guesswork or the mere application of an intuitive sense of justice. While the rates so prescribed are in no sense the mathematical or other result of the application of any formula or combinаtion of formulas, there are certain considerations which constitute the essential basis for *483 the prescription of rates as herein made. Those considerations are :
“ (1) An estimate of the reasonable future cost incurrеd in the furnishing of such service as the public may reasonably be expected to demand from the utility here involved.
“ (2) The value of any class of that utility’s service, where that value constitutes the limitation upon and practical equivalent of the rates charged therefor.
“(3) A reasonable profit'which it is proper for the utility to enjoy under all relevant facts and circumstances.”
The commission relies upon
Federal Power Comm. v. Hope Natural Gas Co.
(1944)
“The commissiоn established an interstate rate base of $33,712,526 which, it found, represented the ‘actual legitimate cost’ of the cоmpany’s interstate property less depletion and depreciation and plus unoperated acreage, working capital and future net capital additions. The commission, beginning with book cost, made certain adjustments not necessary to relate here and found the ‘actual legitimate cost’ of the plant in interstate service to be $51,957,416, as of December 31, 1940. It deducted accrued depletion and depreciation, which it found to be $22,328,016 on an ‘economic-service-life’ basis. And it added $1,392,021 for future net capital additions, $566,105 for useful unoperated acreagе, and $2,125,000 for working capital. It used 1940 as a test year to estimate future revenues and expenses. • It allowed over $16,000,000 аs annual operating expenses — about $1,300,000 for taxes, $1,460,000 for depletion and depreciation, $600,000 for explorаtion and development costs, $8,500,000 for gas purchased. The commission allowed a net increase of $421,160 over 1940 оperating expenses, which amount was to take care of future increase in wages, in West Virginia property taxes, and in exploration and development costs. The total amount of deductions allowed from interstate revenues was $13,495,584. . . .
“In determining the .amount of accrued depletion and depreciation the commission, following Lindheimer v. Illinois Bell Tel. Co.292 U. S. 151 , 167-169; Federal Power Commis *484 sion v. Natural Gas Pipeline Co.315 U. S. 575 , 592, 593, basеd its computation on 'actual legitimate cost.’ It found that Hope during the years when its business was not under regulation did not observe ‘sound depreciation and depletion practices’ but ‘actually accumulated an excessivе reserve’ of about $46,000,000. . . .
“Hope contended that it should be allowed a return of not less than 8.%. The commission found that аn 8% return would be unreasonable but that 6y2 % was a fair rate of return. That rate of return, applied to the rate base-of $33,712,526, would produce $2,191,314 annually, as compared with the present income of not less than $5,801,171.”
From that recital of facts it appears that the Federal Power Commission had at least some basis upon which it was figuring the fair return for the Hope Gas Company. The Public Serviсe Commission in this case appears to have carried the theory which it spelled out of the Hope Case several steps further, and determined to keep the entire basis a secret.
The commission’s order in this case was approрriately termed by the trial court to be arbitrary and unlawful. The inherent fallacy in the commission’s proceeding apрears from its own opinion. It set out as the third element to be considered by it, “A reasonable profit which it is proper for the utility to enjoy under all relevant facts and circumstances.” The order says that the rates established will produce $12,500 of profits per annum.
How can the commission or the reviewing court or the utility or the public determine whether thе profit is proper unless the commission makes specific findings of the “relevant facts and circumstances ?” The commission must determine what those are and set them forth as required by law. Those essential facts which control eaсh case will then determine the rate base.
If the rule were otherwise, the courts would have no rule to apply uрon review, and the commission could on rehearing in this same case a year hence determine that the prеsent rate is *485 unreasonable and that $25,000 of profits would be reasonable for the company to enjoy; and the сonsumers would then be bound by the commission’s abstract conclusion of “reasonableness.” It was not the intention of the lеgislature to be1 stow such arbitrary powers upon the commission, and nothing in the statutes can be so construed.
No purpose would be served by pointing out to the commission the methods to be employed by it on a future hearing; the trial cоurt detailed objections to the procedure adopted by the commission.
The present method of the commission is improper and must be abandoned.
By the Court. — Judgment affirmed.
