Copenhagen Energy plans new 3GW offshore wind farm off Western Australia

Copenhagen Energy has unveiled plans for a third 3GW offshore wind farm off the coast of Western Australia.

The Danish developer plans to use up to 200 turbines with power ratings of 15-25MW, tip heights of 268-385 metres, and rotor diameters of approximately 240-320 metres for its 3000MW Samphire project.

It aims to build the wind farm in a 700km2 site 10-44km offshore between Lancelin and Two Rocks to the south of Western Australia's long coastline.

The company hopes to start construction in 2029 and produce first power in 2031, pending permitting approvals.

Copenhagen Energy believes the project would create around 43,500 jobs during construction and 600 jobs during operation.

The wind farm is named after a salt-tolerant, edible plant – also known as ‘sea asparagus’ – that grows in coastal regions in Australia.

Copenhagen Energy is planning four offshore wind projects off Western Australia – each with a capacity of 3GW. Earlier this year, it unveiled details of its Leeuwin and Midwest projects.

Last month, the government identified an area off the coast of Perth and Bunbury in Western Australia with potential for offshore wind development. It is unknown whether any of Copenhagen Energy’s Western Australia projects are planned in this area.

Copenhagen Energy founder Jasmin Bejdic was formerly head of offshore wind at European Energy. While in the role, European Energy received final approvals for its 240MW Jammerland Bugt and 320MW Omø South wind farms off Denmark.

Copenhagen Energy is also working to develop 3GW of offshore wind capacity off the Philippines and 8GW off Ireland.
