In December 2019, Natel Energy installed their latest turbine, the Restoration Hydro Turbine (RHT D55 - patent pending). This new turbine is a Francis type, as opposed to the linear Pelton machine that was installed in 2017.
With Natel’s help, we modified the civil works - penstock shape, concrete layout, generator location, etc. We also chose to install an electronic system for closing the knife gate out at the dam for better operational control. Once these modifications were complete, the installation of the turbine went very smoothly. Natel had us up and running in a matter of weeks. By the time (mid-June 2020) the water levels got too low to operate, we had generated as much power as we anticipated for a full calendar year. This turbine is significantly more efficient than the earlier design, and we were operating at above 32-kWh when the flows were sufficient, a significantly higher rate than before.
