ESTIMATES BY H. W. BUCK, ELECTRICAL ENGINEER FOR THE Completion of the Electric Lighting Installation for the Reservation and for an Electric Power Plant Report of the Electrical Engineer. NIAGARA FALLS, N. Y., November, 14, 1903. Commissioners New York State Reservation, Niagara Falls, N. Y: Gentlemen. I beg to submit herewith an estimate of the amount required to complete the installation of apparatus and appliances for the illumination of the grounds of the New York State Reservation at Niagara Falls. In the lighting scheme upon which this estimate is based it is intended to take power from the Niagara Falls Power Company's mains at the upper end of the Reservation grounds, the incoming wires to be led overhead to a small fireproof building located as shown in the plan. In this structure will be installed the necessary switchboards for controlling the underground cable system, lightning arresters, and transformer for supplying the lights at the upper end of the reservation. The 2200-volt underground mains will be laid in the conduit already completed from this terminal house to the shelter building. This 2200-volt main will be tapped at its middle point by a transformer for operating lights in the central portion of the reservation grounds. This main will also supply power to a third transformer located in the basement of the shelter building, which will supply the lights in the Prospect Park district. The secondaries of these three transformers will feed into a 220-volt system of mains, also laid in the conduit now constructed. These low voltage mains will be tapped at suitable points with lateral connections leading to the individual lampposts. By this method an excellent voltage regulation can be obtained which will give an uniform brilliancy to all lamps throughout the reservation grounds. It is proposed to install short lampposts, each holding a cluster of about four 16-candle power incandescent lamps. The lampposts will be located approximately as shown in the blueprint plan. Estimated Cost of Complete Installation. 5,000 feet duplex 2200-volt cable @ 20 cents per foot 1,000 00 10,000 feet of cable for 220-volt mains @ 10 cents per 18,000 feet cable for lateral connections @ 10 cents. 1,800 00 $11,800 00 Very truly yours, H.
