Tilt Renewables has reached a final investment decision (FID) on its second wind farm in a matter of weeks, with South Australia following up the momentum generated in WA late in 2025
The 288MW Palmer wind farm in South Australia.will enable construction to commence on the project this year, with it capable of powering 142,000 homes once operational.
In December, Tilt Renewables also announced a FID for its Waddi Waddi wind farm, the first by the company in WA.
Tilt chief executive officer Anthony Fowler said the approval of Palmer was a significant milestone for the company and South Australia.
“It is a win for South Australia, which is leading Australia in the renewable energy transition,” he said. “It is also a win for our neighbours, local communities, and First Nations people who stand to receive more than $13 million in community benefits.
“The Palmer wind farm has been on the drawing board for over a decade and has undergone several changes to reduce its environmental and community impacts.”
It has been a good start to the year for TIlt with Fowler celebrating in December with the FID of the 108 MW Waddi Wind Farm, 150km north of Perth.
“( Waddi Waddi )will be the first wind farm to reach a Final Investment Decision in 2025 and shows that the investment drought for new projects in Australia is finally breaking”.
“We now have everything in place to start construction, strong financial backing from our investors, a 15-year supply contract with AGL, an offer to connect to the SWIS, and planning approvals from local Shire of Dandaragan, State and Federal authorities”.
Reframed in SA
In SA, the Palmer project has undergone technology improvements to support a reduction from 103 turbines to 40, which Fowler said will reduce the impacted area “while still generating a similar level of clean energy”.
“We see Palmer as a great location because the wind resource is strong and consistent, it’s close to existing electricity transmission and is on cleared farmland so grazing can co-exist with a wind farm,” he said.
In late September, Tilt also signed a 15- year power purchase agreement power purchase agreement with AGL to support the Palmer wind farm, with 45 per cent of Palmer’s output to be sold to the gentailer at a fixed price.
Palmer will facilitate more than 200 new jobs during construction and five permanent jobs. Turbine manufacturer Vestas, principal contractor BMD and ElectraNet have been engaged for the build.
Vestas as partner
Vestas will also supply and install the turbines and provide 30 years of service for Tilt Renewables Waddi Wind Farm.
The WA project will feature 18 V162-6.0 MW EnVentus™ wind turbines at a 125-metre hub height, optimised to boost energy output while supporting positive environmental and federal environmental EPBC compliance.
Vestas said the WA project was another win for the company and the state, positioned between the Yandin and Warradarge wind farms—two of Western Australia’s most successful renewable projects
Vestas Senior Vice President & Country Head, Australia & New Zealand Danny Nielsen said the Waddi Waddi project reinforces Vestas’ proven track record in delivering wind turbines, installation, construction, and long-term service across the stateadded:
“This project reinforces Vestas’ presence and long-term commitment in Western Australia. We’ve delivered some of the state’s most successful renewable energy projects, and Waddi Wind Farm represents the next chapter—expanding the SWIS with high-performing wind power that delivers sustainable energy and strengthens energy security for decades. We value our long-term partnership with Tilt Renewables and look forward to Waddi providing clean, and secure energy for years to come.”
