The statutes relating to municipal light plants prescribe that the excess of the estimated annual expense (including the gross expense of operation, maintenance and repair, interest on the debt created to pay for the plant, depreciation, sinking fund or debt requirements, and loss if any, in the operation of the plant during the preceding year) over the estimated income from sales to private consumers shall be included in the annual appropriations for maintenance and in the tax levy. For this excess, which it must thus raise by taxation, the city or town receives its street and public building lighting. In some instances electricity furnished to public buildings is metered, charged at the same rates as to private consumers, and paid out of other appropriations in the same manner as though the plants were privately owned. In some instances also specific appropriations are made for street lighting, presumably with the number and type of lamps to be supplied in view. For these reasons, while it is desirable to know from the standpoint of the city or town as a municipal corporation what it is getting for the money raised for the plant by taxation, and on a basis comparable with the cost to it of lighting its buildings and streets if served by a privately owned plant, such results can only be obtained by estimates of the electricity used in public buildings where not measured, and computations of the cost per street lamp based on the average number of lights used per day and an apportionment between different types of lamps according to the energy theoretically necessary to supply them. In the three pages following, the data used in arriving at these results and the results themselves will be found tabulated. The second table is devised upon the theory that for all its expenditure the municipality receives only its street lighting and the income from its commercial business, and that the cost of the former to the city or town is the difference between such income and the entire cost of carrying on the business. |
