Synergy and Water Corporation have inked long-term power purchase agreements (PPAs) with WA wind farms as the state looks to exit coal-fired generation in 2030.
The 470-megawatt (MW) Parron Maam Marang wind farm and the 130MW Kondinin wind farm, both expected to supply electricity by late-2028, have signed long-term PPAs with Synergy.
Alinta Energy’s Marri wind farm, set to come online in 2029, has done the same with Water Corporation, with the state-owned entity to procure 330MW of the project’s 550MW wind capacity.
The agreements amount to more than one gigawatt of electricity – above WA’s commitment to deliver 810MW of wind generation – with generation from the three wind farms topping the capacity of WA’s remaining coal-fired power plants, which includes the Muja, Collie and Bluewaters power stations.
Alinta Energy executive director – merchant energy Ken Woolley said the Water Corporation PPA provides a robust foundation for the Marri wind farm.
“Participating in the largest long-term renewable energy offtake in WA’s history, with an essential service provider like Water Corporation, is a boost for the project’s commercial foundations and pathway to a final investment decision (FID),” he said.
The Marri project is still subject to approvals before its progresses to an FID, with Alinta Energy working with stakeholders to progress its social licence obligations.
Elsewhere, Synergy has also contributed $28.8 million to the stage two expansion of the Warradarge wind farm, which will see an additional 30 turbines (on top of stage one’s 21 wind farms) constructed to take the asset’s capacity to 283MW.
Warradarge stage two commenced construction in July last year.
