470 MW Parron Maam Marang wind farm reaches financial close, the largest in Australia in two years

# What happened Parron Maam Marang, a 470 MW wind project in Western Australia developed by Atmos Renewables, has reached financial close (FiD) and will move into construction. The announcement was made by WA energy minister Amber-Jade Sanderson. Atmos will retain an ownership stake and operate the wind farm once complete, the company said.

# Why it matters now This FiD is the ninth Australian wind project to secure finance in the past 12 months and the largest to do so in more than two years. The cluster of recent financial closes signals a break in the investment drought that stalled new-build wind projects. Government-backed arrangements — notably power purchase agreements with Synergy and underwriting via the federal Capacity Investment Scheme (CIS) — are enabling deals that face otherwise challenging market conditions.

# Project and commercial details

• Size and location: 470 MW in the wheatbelt, about 200 km north of Perth.

• Ownership and operations: Atmos will retain an ownership interest and operate the wind farm after completion.

# Related activity around Australia Western Australia is driving most of the current activity. Other WA projects under construction or fast-tracked include Waddi, Narrogin, Kondinin, King Rocks, and an extension at Warradarge. Fortescue is building the 130 MW Nullagine project in the Pilbara to power mining operations. Across the country, recent FiDs and starts include Palmer and Carmody's Hill in South Australia, the state-owned Delburn project in Victoria, and the 408 MW Gawara Baya wind-and-battery project in Queensland.

# Battery projects and Atmos' wider wins Atmos announced it also reached financial close on the Teebar battery energy storage system in Queensland: 400 MW and 1,600 MWh, to be built with Valo technology and delivered by Enerven. Atmos' CEO Nigel Baker said the company has brought nearly 1 GW of new capacity to market through CIS awards, while noting that CIS awards are a step in a longer process requiring financing, grid access, and delivery plans.

# Bigger picture and constraints

# What to watch next

• Construction progress and timelines for Parron Maam Marang.
• Delivery of the Teebar BESS and the Merredin battery referenced by Atmos.
• Whether more large-scale FiDs follow in NSW and Queensland to close the gap to the 2030 target.

# Bottom line Australia, enabled in part by state PPAs and federal underwriting. The scale of current projects and number of FiDs is meaningful, but substantially bigger and faster deployments are still needed to meet national renewables targets by 2030.
