The following opinion was filed February 3, 1914:
For many years prior to 1907 the plaintiff was a public utility. It did not elect to surrender its franchises and to take in lieu thereof the indeterminate permit provided for by the Public Utilities Law of 1907 (ch. 499), sec. 1797m — 1, Stats., and succeeding sections.
Ch. 596, Laws of 1911, was published and became effective on July 8, 1911. This act in effect provided that any franchises theretofore granted to a public utility by the state or through any of its agencies wras so altered and amended as to *6constitute and be an indeterminate permit within the terms and meaning of secs. 1797m — 1 to 1797m — 108, inclusive, of the Statutes of 1898, and subject to all the terms, provisions, conditions, and limitations of said sections. The amended franchise is given the same force and effect as a license, permit, or franchise granted after July 11, 1907, to any public utility subject to the provisions of the Public Utilities Law of 1907.
Sub. 3, sec. 1797m — 74, Stats., being part of the Public Utilities Act, provides:
“No municipality shall hereafter construct any such plant or equipment where there is in operation under an indeterminate permit as provided in this act, in such municipality a public utility engaged in similar service, without first securing from the commission a declaration, after a public hearing of all parties interested, that public convenience and necessity require such municipal public utility.”
The appellant contends that by force of said eh. 596, Laws of 1911, it received an indeterminate permit in lieu of the existing franchises under which it operated, and became subject to the Public Utilities Law to the same extent that it. would have become subject thereto had it surrendered its franchises under the 1907 law and elected to receive in lieu thereof an indeterminate permit as provided by ch. 499, Laws of 1907 (sec. 1797m — 77). The plaintiff being subject to the Public Utilities Act after July 8, 1911, it insists that it was unlawful for the defendant city to engage in the business of commercial lighting after that date without a certificate of convenience and necessity from the railroad commission, and it is conceded that no such certificate was procured and it appears by inference that none was asked for.
The defendant insists that it had the right to proceed without any certificate from the railroad commission, for the following reasons:
(1) The clause in the franchise granted the plaintiff in 1904 by which the defendant expressly reserved to itself the right to engage in the business of commercial lighting is still *7in force, and in any event, the plaintiff having accepted such franchise with the provision referred to, it should not now be heard to object to the right of the city to exercise the privilege so reserved.
(2) By a resolution passed February 21, 1911, the city, as it had the right to do at that time, evinced an intention to enlarge its plant so as to engage in the business of commercial lighting, and it should be held that thereafter the city became a public utility in the business of commercial lighting.
(3) The city was in fact a public utility engaged in the commercial lighting business since the summer of 1906, and therefore it was not affected by ch. 596, Laws of 1911.
The circuit judge held in substance that there was a contract between the parties by which it was agreed that the city might at any time engage in the commercial lighting business; that the obligation of this contract could not be impaired, although the legislature might prohibit the city from building a lighting plant; that the contract was not affected by ch. 596, Laws of 1911, and that under the provisions of the ordinance of 1904 referred to the plaintiff was estopped from claiming that the city did not have the right to engage in the commercial lighting business. The trial judge also said he was inclined to thint the position was well taken that the city was a public utility engaged in the business of commercial lighting long prior to the passage of the act of 1911.
The Public Utilities Law was undoubtedly framed on the theory that certain kinds of business were of such a character that the duplication of plants for the purpose of carrying them on was undesirable because it resulted in an economic waste, the loss from which in the end usually fell upon the consumer. As to some kinds of business, such as that of operating telephone lines, duplication is not only an added expense to the user, but is apt to be a positive nuisance. Competition in the public utility business in our cities in the end generally resulted in consolidation or an agreement between competing companies as to the rates to be charged. In either *8event the rates were usually adjusted so as to cover fixed charges and to yield a return on the cost of constructing the competing plants. These are matters of common knowledge. One of the main purposes of the law was to avoid duplication, and it was thought that by efficiently controlling the rates to be charged by a single utility the consumer would derive the benefit resulting from economy in production. In construing the Public Utilities Law the apparent purpose of the legislature should be kept in mind.
When ch. 596, Laws of 1911, was passed, it took from the plaintiff some rights and privileges which it had and conferred some privileges on it which it did not have. It also conferred some rights on municipalities in regard to acquiring existing plants which they did not before have. After the passage of this act, sub. 3, sec. 1197m — 74, above quoted became part and parcel of the plaintiff’s franchise.
The main propositions upon which this case was decided by the lower court would seem to be untenable under our decisions. In brief it was held in La Crosse v. La Crosse G. & E. Co. 145 Wis. 408, 130 N. W. 530, that when a public utility comes under the 1907 law it surrenders its existing franchise and that its rights and liabilities are then fixed and determined by the provisions of the Public Utilities Act. The writer of this opinion did not agree with the decision in the La Grosse Case, but has no doubt that where there is an express provision in the Public Utilities Law which is inconsistent with a provision .contained in the franchise surrendered, the latter is abrogated. The quoted section of the Public Utilities Act is inconsistent with the provision of the 1904 ordinance granted to the plaintiff upon which the defendant relies; so the case here made by the plaintiff is stronger than that made by the defendant in the La Grosse Gase. It is also decided in this latter case and in other cases that the provision of the 1904 ordinance relied on might be abrogated by the legislature. An agreement by which a city reserved the right to do a commercial lighting business has no *9more of the essence of a contract protected by the constitution than one whereby the city was entitled to receive a license fee for the use of its streets, which was the question involved in the La Crosse Oase, or one by which an interurban railway company agreed not to exact to exceed a certain rate of fare, which it was held did not deprive the legislature of the right to regulate rates in Manitowoc v. Manitowoc & N. T. Co. 145 Wis. 13, 129 N. W. 925. What was said in the La Crosse Case in reference to the effect of taking an indeterminate permit was approved in Calumet S. Co. v. Chilton, 148 Wis. 334, 356, 135 N. W. 131. The language of sub. 3, sec. 1797m — 74, positively inhibits a municipality from constructing any plant or equipment where' there is in operation under an indeterminate permit a public utility engaged in a similar service, without first procuring a certificate of convenience and necessity from the railroad commission. The plaintiff, after July 8, 1911, fully answered the calls of the statute, and the defendant had no right to proceed without the certificate unless prior to that date it had constructed a plant or equipment to engage in the business of commercial lighting within the meaning of the statute.
The argument is made that because the plaintiff accepted a franchise reserving to the city the right to engage in the commercial lighting business, it is now estopped from asserting that the city has no such right. The argument is not convincing. The plaintiff was apparently satisfied with its franchise. It might have voluntarily surrendered it and taken an indeterminate permit, but it did not see fit to do so. So long as it retained its original franchise the city had a perfect right to engage in the commercial lighting business. The legislature, however, intervened and took away the existing franchise of the.plaintiff and substituted another for it. Plaintiff could no longer claim the benefits of its former franchise, and it would hardly seem fair to impose on it the burdens imposed by the old franchise, which were expressly taken away by the new. The state substituted a franchise of its *10own making for one npon which, the parties had agreed between themselves. Conceding that the power to do this existed, it is difficult to see how the plaintiff shonld be held es-topped from claiming the benefits of any rights given by the substituted franchise.
The main contention of the respondent, as stated by its counsel, is that on July 8, 1911, and for a long time prior thereto the defendant was a public utility doing a commercial lighting business and therefore was not affected by ch. 596, Laws of 1911. The facts upon which this claim is based have been fully set out in the statement of facts.
A city in lighting its streets and public buildings is performing a governmental function. It is not liable for the negligence of its servants in .performing that duty. On the other hand, when a city engages in the business of supplying light to private consumers, it is performing a proprietary or private function, and it is liable for the negligence of its servants. Piper v. Madison, 140 Wis. 311, 122 N. W. 730; Evans v. Sheboygan, 153 Wis. 287, 141 N. W. 265, and cases cited. The two kinds of business are separate and distinct. 1 Dillon, Mun. Corp. (5th ed.) § 109; Ashland v. Wheeler, 88 Wis. 607, 60 N. W. 818; Kaulcauna E. L. Co. v. Kaukauna, 114 Wis. 327, 89 N. W. 542.
There can be no doubt that when the city built its original plant it was built for the purpose of lighting the streets, and possibly the public buildings owned by the city. It was built in the exercise of a governmental function. The resolution adopted was broad enough to cover both kinds of lighting, but the plant constructed was wholly inadequate for the dual purpose. It appears from the evidence of one witness that the building in which the equipment was placed was large enough to accommodate another light engine. Other evidence indicates that the equipment was placed in the waterworks building. After the plant had been running a few months it was thought that some private lighting could be done, so wires were run some six or seven hundred feet to *11the store building of the mayor, and that was lighted on the first and second floors, as well as the dwelling honse of the mayor’s partner, located about twenty feet from the store. These lights were discontinued about the middle of the year 1908, because the city was unable to generate the necessary current to run them. Thereafter for a period of more than three years before the passage of ch. 596, Laws of 1911, no private lighting was done by the city. In addition to the private lighting done as above stated, the city furnished current for two days in 1906 or 1907 to one other consumer, but was obliged to quit because it could not generate the necessary current. The original proposed expenditure for a lighting plant was only $10,000. No doubt the poles used for public lighting might also be used in connection with the business of private lighting, and possibly some of the other equipment. The only equipment which the city appears to have had which was not an essential part of the public lighting plant consisted of two or three transformers, two or three poles, and six or seven hundred feet of double wire. These were procured or constructed in connection with the lighting of the mayor’s store building and the residence of his partner.
Under the facts stated we do not think the city was a public utility engaged in the business of commercial lighting at any time prior to July, 1911. According to the census of 1905 the city of Menasha had a population of 5,960. The furnishing of a few lights to one store and one residence for a short time, wTe do not think made the city a public utility under the doctrine of Cawker v. Meyer, 147 Wis. 320, 133 N. W. 157. However this might be, the city had ceased, to perform any function as a public utility for more than three years before the passage of the 1911 act.
It is true that the action of the city in 1911 contemplated the enlargement of the existing plant, but the purpose of making the enlargement was to enable the city to embark in a new and independent business, to wit, that of furnishing commercial light in its private or proprietary capacity. To *12this end bonds to the amount of $40,000 were sold. Nothing, however, was done toward extending the plant or voting the bonds therefor nntil after July 8, 1911, except that on Eebruary 21, 1911, the council passed a resolution which amounted to a declaration of intention to enlarge the existing plant so as to engage in the business of commercial lighting.
After July 8, 1911, the plaintiff was a public utility operating under an indeterminate permit and furnished light to the inhabitants of the city of Menasha. The city was not and had not been engaged in this business for at least three years, and we think never had been engaged in such business. Under the statute quoted the city was prohibited' from “constructing any plant or equipment” for the purpose of engaging in the field occupied by the plaintiff, without the consent of the railroad commission. When the original plant was constructed, it may have intended and probably did intend to embark in the commercial lighting business at some future time, but it did not do so or take any steps in that direction until after July 8, 1911.
Respondent’s counsel argue that under the decision in Neacy v. Milwaukee, 151 Wis. 504, 139 N. W. 409, the city became a public utility for the purpose of engaging in the lighting business prior to July 8, ÍL911. The cases are very dissimilar in their facts. Eive years before the Public Utilities Law was passed, the city of Milwaukee determined to erect a municipal lighting plant and voted bonds for that purpose in 1904. It was tied up by various proceedings in the courts, but in 1906 it issued bonds for this purpose to the amount of $150,000 and purchased a site for $60,000. Before the Public Utilities Law was passed the city expended other large sums of money for and in connection with the construction of an electric light plant. Under these circumstances it was perhaps inferentially held in the Neacy Case that a certificate from the railroad commission was not necessary, because the city had reached a definite conclusion to build, had provided the necessary funds therefor, had pro*13cured its site, and was building as rapidly as it could before the Public Utilities Law was passed and when it had a perfect right to proceed without any certificate of convenience and necessity. About all that can be said in the instant case is that the city from 1905 on and prior to July 8, 1911, evinced an intention to embark in the commercial lighting business at some indefinite time in the future, and that it had made some trifling expenditures in connection with the lighting of the store building and residence referred to. No definite steps were taken to enter the private lighting field and no funds were provided for that purpose until after July 8, 1911. It is reasonable enough to say that sub. 3, sec. 17 Olm — 74, was not intended to prevent the completion of a plant where the construction of one was well under way when the law was passed. We think it would not be a reasonable construction of it to hold that mere intention to build a-plant would be sufficient to render the law inapplicable.
State ex rel. Kenosha G. & E. Co. v. Kenosha E. R. Co. 145 Wis. 337, 129 N. W. 600, has some bearing on the question. There the city entered into a contract with the street railway company to do its lighting, and the latter expended a considerable sum of money to provide the necessary equipment to carry out its contract. Before the city succeeded in passing an ordinance granting the street railway company the right to place its poles and wires in the streets, the Kenosha Gas & Electric Company surrendered its franchise and took the indeterminate permit provided for by the Public Utilities Law, and it was held that the ordinance passed after such surrender was void and that the street railway company acquired no rights thereunder. The fact that a preliminary contract was entered into and considerable expenditures were made thereunder before the competing Titility took an indeterminate permit was not considered sufficient to deprive it of the benefits conferred by sub. 1, sec. 1797m — 74.
The respondent no doubt constructed its plant in the best of faith. We realize that this decision leaves it in an unfor-*14tímate predicament. We think the law is reasonably plain, and, thinking so, it is not for us to undertake to amend it or to defeat the legislative will by indulging in a strained construction of it. Our duty is to declare the law as it is written. If it deals harshly with the defendant, it has its remedy before the railroad commission or the legislature. "Where a city builds a plant adequate only for the purpose of doing its own lighting, hut intends to enter another field of operation in the indefinite future, we do not think it can reasonably be said that because of such intention and because a small portion of the equipment in use may also be useful in the new operation, it is in fact engaged in such new operation. We cannot escape the conclusion that prior to July 8, 1911, the city had built an,d was operating a plant to do its own lighting, and that thereafter it provided the necessary funds and proceeded in its proprietary capacity to provide a plant to furnish commercial lighting, and that in doing so without a certificate of convenience and necessity from the railroad commission it was constructing and equipping a commercial lighting plant in violation of sub. 3, sec. 1797m — 74, because there was already a public utility operating such a plant in the city under an indeterminate permit.
By the Court. — Judgment reversed, with directions to enter judgment in accordance with this opinion.
