Title: Development of a project on North Unit Irrigation District’s Main Canal at the Monroe Drop, using a novel low-head hydropower technology called the SLH100

Abstract

Natel Energy is a low­-head, distributed hydropower company based out of Alameda, CA. Natel manufactures and sells proprietary hydroelectric turbines called hydroEngines® that are suitable for low-­head, high-­flow settings, and range from 30kW to 1 MW of capacity per unit. Natel’s hydroEngine is a state­-of­the-­art two stage impulse turbine, using blades mounted symmetrically on two belts perpendicular to the axis of travel, and using linearly­-moving foils, rather than a rotor, to enable efficient conversion of kinetic energy of large volumes of water at low head with no risk of cavitation. In addition, the hydroEngine can be installed at or above tailwater level, reducing the excavation necessary to build the powerhouse and thus reducing total installed cost and project footprint. Thus, the hydroEngine technology enables a new generation of small hydro installations with low cost of project development, fish-­friendly operations, and small project footprint. In September of 2015, Natel Energy formally commissioned its first project installation in Madras, Oregon, installing 1 SLH100 turbine at an existing drop structure on the North Unit Irrigation District (NUID) Main Canal. The water falls between 13.5 feet to 16.5 feet at this structure, depending on flow. The plant has an installed capacity of 250 kWmore » and an expected annual generation of approximately 873 MWh. The plant operates at an annual capacity factor of 40%, and a capacity factor over the irrigation season, or period of available flow, of 80%. Annual capacity factor is calculated as a percentage of plant operating hours relative to a total of 8,760 hours in a year; because the irrigation canal in which the Project is located only runs water from April to October, the available flow capacity factor is higher. Net greenhouse gas reductions from the Monroe Project are estimated to be 602 tCO2/year. The purpose of this report is to provide an overview of the specifications for Natel’s first commissioned project, the project development process, the plant’s performance, project costs, and the construction, installation, and commissioning process. We hope that this report will provide useful context for assessment of the hydroEngine as a viable technology choice for future distributed, low-­head hydropower projects, as well as assessment of the bankability, performance, reliability, and cost of the hydroEngine.« less
