The High Line Canal Hydroelectric Project is rated at 530 kilowatts (kW), and features benefits that accrue due to relatively low costs of $2,100 per installed kW, average annual energy production of 1.4 million kilowatt-hours (kWh), low operating and maintenance costs, and close proximity to two operating, City-owned hydroelectric powerhouses. This unique hydroelectric project involved the use of a single regulated semi-Kaplan submersible turbine/generator installed at a seventy-five year old U.S. Bureau of Reclamation canal drop. Innovative design techniques were employed which permitted the submersible turbine/generator unit to be installed after the site construction was completed without any disruptions of water deliveries in the canals. The design/build contract was awarded in March, 1987, and the project was completed in August, 1988, at a total cost of about $1,100,000.
