Australia has launched a new tender under its Capacity Investment Scheme (CIS) to support 1.8 GW of new renewable power generation capacity in Western Australia (WA), within the Western Energy Market (WEM), according to a statement from Australia’s Minister for Climate Change and Energy (25/08/2026).
The Minister said the new tender, known as Tender 11, will also be the first to require participation in the government’s newly introduced Developer Rating Scheme (DRS). The scheme is intended to give landholders and local communities greater transparency regarding the track record, capabilities and conduct of renewable energy developers and transmission companies.
“CIS tenders in Western Australia announced this year have already backed 10 projects delivering 1.9 GW of renewable generation and 482 MW of storage, delivering enough renewable electricity for more than 1 million WA households and enough storage to support more than 400,000 households during peak demand”, according to the government’s statement.
The new tender comes only a few months after the results of the previous generation tender in WA were announced. The winning projects comprised six wind parks and one solar-plus-battery hybrid project, with a combined capacity of 1.886 GW.
Bidding for Tender 11 will open on 27 August 2026 and close on 22 October 2026.
Western Australia is now seeking to accelerate the deployment of new generation capacity to replace the remaining state-owned coal-fired generators, which are scheduled to shut down by the end of 2029. The state has also recently announced PPAs with four major wind projects with a combined capacity of more than 1 GW (Renew Economy, 25/08/2026).
