PROJECT PROFILE: DUNCAN DAM
World’s First VAHT Discharge Channel Pilot
The Duncan Dam located near Kaslo, British Columbia is a reservoir with no hydroelectric production and a current velocity of approximately 2 m/s.
Collaborating with one of Canada’s largest electric utilities, BC Hydro, and their clean energy subsidiary, Powertech Labs, Instream deployed a prototype array of four 25kW turbines proving VAHT technology was an effective way to capture clean energy in a dam discharge channel or “tailrace.”
Pilot Objectives:
-
Demonstrate VAHT technology as a viable technology in a dam tailrace setting
-
Collect and analyze turbine performance and waterway impact in single and multi-unit arrays
-
Test decommissioning strategies and plans to ensure no adverse impact to the environment
Pilot results:
-
Successfully demonstrated VAHT technology
-
Successfully collected a large dataset used in the creation of a new BAE Systems rotor and array designs
-
Produced a third-party report providing insight into real-world operations of the technology; including decommissioning
