The federal government has launched the latest tender under its flagship Capacity Investment Scheme, seeking another 1.8 GW of new solar and wind capacity in Western Australia.

The latest round of the Australian government’s Capacity Investment Scheme (CIS) is officially open, providing renewable energy project developers with the opportunity to register and bid for underwriting contracts for generation projects in Western Australia’s Wholesale Electricity Market (WEM).

CIS Tender 11 is seeking about 1.8 GW of renewable energy generation capacity with projects supported through the tender expected to be operating by 2030. Registrations for the tender are already open with bids opening on 27 August alongside the release of the tender guidelines.

Australian Energy Minister Chris Bowen said the tender will be the first to require participation in the government’s new Developer Rating Scheme (DRS), that is designed to give landholders and local communities greater transparency about the track record, capability and conduct of renewable energy developers and transmission companies

“Western Australia needs more power as its economy and population grow, and this tender will bring forward another 1.8 GW of new generation to help deliver it,” Bowen said.
