INSULATES WITH SUPEREX-85% MAGNESIA TO LOWER POWER PRODUCTION COSTS Hydro Power American Development of Power on the Niagara River. By Harold I How ell, Niagara Mohawk Power Corp. After outlining the history of -power developments at Niagara Falls and the treaty of 1950 to permit Increased water diversion for power generation, the au thor describes the engineering plans for the development on' the U. S, side of the Falls proposed by five public utility companies. Based on construction costa in the early part of 19S3, the complete project is estimated to cost $390,000,* 000. To carry out this plan the follow ing construction sequence it recnm* mended to give the final development shown in drawing, left, above. 1. Construct one 47*ft diameter con crete-lined tunnel about 5 miles long from Conners Island intoke to the Lewis ton power house. This development will use about 30,000 cfs under o head of 314 ft and will operate in parallel with the existing Schoellkopl and Adams stations. Added power capacity will amount In 675,000 kw. 2/Construcl the second 47-ft diameter tunnel, .which will add about 675,000 kw more capacity. Schoellkopl station will continue to operate as will Adams when water is available within treaty limits. 3. Construct the pumped-atorage do* velopment to provide greater peakload output at the Lewiston power house. This will include a single 47-ft diameter tunnel 1 mile long, a pumping generat ing station to add 130,000 kw of gen erating capacity and' a pump-storage reservoir of about 22,000 acre-feet. 4. Construct (he lower-river project tunnel about 3 miles long by 42 ft in dia. This development will add 120,000 kw and use 94-ft head In the lower river between the Schoeltkopf and Lew iston power houses. This plan will add about 1,600,000 kw of generating capacity to the two existing plants which have o total of 444,000' kw installed. The Increase in annual energy generation will be about 8-billion kwhr, bringing the total on the U. S/slde to about 12*billion kwhr. The proposed Niagara development can 'Pacific Gas and Electric Com* [invested $80,000,000 in Its new be completed in six years and power* from the first step can be made available^ jttO-horiepowcr electric generating a it Moss Landing, California...the ihrco year. .he. connic.i.o j"- "k* ^ " APCPow.noaumb',. & $&l,,!jokn,.M.nvill.Sup,,.,- Falcon Dam and Power Plants.

J-M 85% Mogncsla is the leading in sulation for temperatures to 600F. It will not distort regardless, of its length of service. Jt fits snug, stays tight. Heat savings, therefore, remain constant for the life of the equipment on which it is applied. Whatever the insulation--it must be properly engineered and installed to pay maximum dividends. That's why Jobns-ManWIie offers industry the serv ices of experienced J-M Insulation Engi neers and J-M Insulation Contractors. These men stand ready to combine their talents and give you an insulation job that wifi more than pay off your initial investment with maximum fuel savings.
