Western Australia Secures Over 1 GW of Wind Power to Replace Coal

Western Australia has announced the signing of several long-term Power Purchase Agreements (PPAs) to supply electricity from new onshore wind farms in regional areas. These agreements, concluded by the Cook Government, bring contracted wind capacity to over 1 gigawatt, exceeding the state's official target of 810 MW set to replace coal-fired power stations. The rise of onshore wind development is also visible across the Asia-Pacific region, where Hai Long installs its first wind turbine using a locally assembled nacelle in Taiwan and where Vestas and Japan's METI agree on local wind turbine nacelle assembly.

Synergy and Water Corporation Sign New PPAs

Among the retained projects is the Parron Maam Marang Wind Farm, with a capacity of 470 MW, developed by Zephyr Energy, a joint venture between Parron Developments and Atmos Renewables. Under the signed agreement, state-owned utility Synergy is designated as the energy buyer for this project. The facility is targeted to begin supplying electricity by late 2028. These long-term PPAs commit Synergy to procure energy from multiple projects upon their completion.

In a separate deal, the Water Corporation will source 330 MW from the Marri Wind Farm, which has a total capacity of 550 MW. The project is scheduled to come online in 2029. Together, the two agreements contract a capacity exceeding 1 GW, surpassing the government's 810 MW wind target set to offset output from the state's remaining coal-fired power stations.
