OPT PowerBuoys float on the surface and generate electricity in the water so they are susceptible to storms and issues with in-water electricity generation, at least that's my take on it. If CNM is chosen for that final 5 MW then they are buying local plus they are buying simplicity and elegance, in my view. I didn't realise there was 5 MW up for grabs for unproven technology. I think CNM has a great chance now. Does the 5 MW site have to be at Binningup? I guess it makes sense, but it could be anywhere along the WA coast in theory.

OPT PowerBuoy details:

"OPT's PowerBuoy® wave generation system uses a "smart," ocean-going buoy to capture and convert wave energy into low-cost, clean electricity.

The rising and falling of the waves off shore causes the buoy to move freely up and down. The resultant mechanical stroking is converted via a sophisticated power take-off to drive an electrical generator. The generated power is transmitted ashore via an underwater power cable.

A 10-Megawatt OPT power station would occupy only approximately 30 acres
(0.125 square kilometers) of ocean space.

Sensors on the PowerBuoy® continuously monitor the performance of the various subsystems and surrounding ocean environment. Data is transmitted to shore in real time. In the event of very large oncoming waves, the system automatically locks-up and ceases power production. When the wave heights return to normal, the system unlocks and recommences energy conversion and transmission of the electrical power ashore.

• Buoys are spaced to maximize energy capture.

• Rugged, simple steel construction.

• Utilizes conventional mooring systems.

• Simple installation using existing marine vessels and infrastructure.

• Scalable to large power stations (100+ MW)"
