Site was used to test turbine under extreme conditions
Upstream (Ebb direction):
• Perfect orientation of turbine
• Low turbulence – no large scale eddies
Downstream (Flood direction)
• Very large turbulence – large scale eddy super-imposed
Very good test environment: If turbine can be controlled in both very extreme directions, understanding of technology is maximum
Due to site limitations theoretical capacity factor cannot exceed 17%
26
first test results are very promising
