Small-scale hydroelectric power demonstration project: South Consolidated Hydroelectric Project. Final technical and construction cost report
The Salt River Project Agricultural Improvement and Power District (Salt River Project) constructed a 1400 kW low-head hydroelectric power demonstration facility at a site on the Project's South Consolidated Canal located just northeast of Mesa, Arizona. The site is characterized by a mean irrigation season flow of approximately 540 cfs (April to October) and a net head of 35 ft. The feasibility assessment determined that 86% of the annual energy available in the water (after deductions for losses by friction and conversion equipment) could be recovered by installation of one standardized, horizontal axis adjustable blade propeller turbine and a suitably matched generator rated at 1400 kW. This equipment was installed in a conventional arrangement of intake, penstock, powerhouse and tailrace situated between two adjacent canals. Analysis of monthly flow duration data indicated an annual power generation potential of approximately 5,900,000 kW-h. The energy thus generated will displace the highest cost energy on the Salt River Project system, thus providing a direct benefit to Salt River Project customers. The total present worth of energy and capacity benefits over the 50-y life of the project is $8,662,000 compared to a present worth of annual operating costs of $2,001,000 and capital investment costs of $2,600,000, thus yielding a benefit/cost ratio of $8,662,000/$4,601,000 = 1.88.
