Show THE PLANT ESTIMATED Capacity 100,000 Kva; ( 100,000 KW. maximum} Four generators. First Cost $ 9,000,000.00 Unit Cost --------- 90.00 per Kva. Thermal efficiency 16,500 BTU. per Kwhr. Free condensing water, no portion of diking expense. Fixed charges @ 14- 1/ 4$. Local labor at nominal wages. Plant to operate on a maximum base lead, which load can be adjusted to fit plant conditions. ESTIMATED ENERGY COSTS For 75> 000 Kw. average load, ( 75$ average plant use). 100$ power factor. Total Cost of energy with coal @ $ 2.00 $ 2,60 Cents per Kwhr. 0.421 0.452 Dollars per KW. year 36.80 40.50 Dollars per H. P. year 27.25 .30.00 Other load conditions would change these energy costs about as follows: $ 2.00 # 2.60 $ 2.00 | 2.60 Cost per kilowatt- Cost per H. P. Year Load Factor hour I [ Cents) Dollars 75$ 0.421 0.460 $ 27.25 $ 30.00 70 0.441 0.480 28.80 31.40 60 0.493 0.530 32.20 34.70 50 0.563 0.602 36.80 39.40 40 0.671 0.700 43.70 45.65 30 0.849 0.887 55.40 58.00 20 1.205 1.245 78.70 81.40 10 2.28 2.320 149.00 150.00 The costs of energy would be greatly increased for low power factors, and low load factors, such as are encountered in ordinary commercial service, where the loads do not hold a constant value, year in and year out. - 15 - |
