Game-Changing: SA's Largest Wind Project Delivers Electricity at Half Market Price
While Aussie families brace for another year of rising electricity bills in 2025, South Australia just flipped the switch on a massive money-saver. The 412MW Goyder South Wind Farm—now fully operational as the state's renewable powerhouse—is generating clean electricity at rates that make traditional power look obsolete.

The Numbers That'll Make Your Power Company Nervous
Here's the kicker: Neoen's Goyder South locked in Australia's lowest-ever electricity price at just 44.97/MWh∗∗.With current wholesale rate shitting∗∗44.97/MWh∗∗.With current wholesale rates hitting∗∗115-125/MWh in early 2025, this wind giant near Burra is producing power for less than half the market price. It's like Netflix offering subscriptions for $5 while others charge $15.
What This Monster Delivers:
75 towering turbines (each 230m tall—higher than Sydney Tower)
Powers 225,000+ South Australian homes annually
Boosted SA's wind capacity by 20% overnight
Part of the massive Goyder Renewables Zone masterplan
BHP's Bold Move: Ditching Coal for "Baseload Renewables"
In a deal that's reshaping Australian industry, mining giant BHP signed two revolutionary agreements with Neoen:
200MW from Goyder South (backed by Blyth Battery) for Olympic Dam operations
300MW from upcoming Goyder North (with 200MW/800MWh battery storage)
This proves what critics said was impossible: renewables can power 24/7 heavy industry. When complete, the entire Goyder complex will feature over 1GW of wind and up to 3.6GWh of battery storage—making it Australia's renewable energy colossus.
SA Racing Ahead: 100% Net Renewables by 2027
Energy Minister Tom Koutsantonis isn't mincing words: "South Australia is the global renewable energy leader, and projects like Goyder South prove why international investors are flocking here."
2025 Renewable Rankings:
South Australia: 73% renewable generation (targeting 85% by year-end)
Tasmania: 98% (mostly hydro)
Victoria: 40% renewables
NSW: 36% renewables
Queensland: 28% renewables
Breaking: January 2025 Energy Market Update
AEMO's latest forecast shows SA wholesale prices could drop 18-22% by mid-2025 as Goyder South hits stride. Meanwhile, the Albanese Government's Renewable Energy Superpower plan includes $2 billion for SA grid upgrades, fast-tracking more projects like Goyder North.
Coal's Death Spiral Accelerates:
Eraring (NSW): Closure moved to August 2025
Yallourn (VIC): Shutting 2028
Callide B (QLD): Offline after explosions, unlikely to return
The ACT's Genius Play Paying Off Big Time
The ACT Government's 2020 deal for 100MW at $44.97/MWh is printing money. With spot prices above 100/MWh,ACTresidentspocketed∗∗100/MWh,ACTresidentspocketed∗∗2.9 million in just one quarter**. Over 14 years, this could return $150+ million to territory coffers—proof that betting on renewables pays dividends.
Community & Environmental Wins Beyond Watts
400 construction jobs created (35 permanent positions)
$250,000 yearly for local community funds
Funded creation of Worlds End Gorge National Park—a first for Australian renewables
Zero water consumption (coal plants use 2.2 billion litres annually)
Prevents 1.8 million tonnes of CO2 yearly
Brookfield's $11 Billion Bet on Australian Wind
After acquiring Neoen, Canadian giant Brookfield announced plans to quadruple Australian renewable investments by 2030. CEO Xavier Barbaro calls Goyder South "the template for global energy transition," with similar projects planned for Western NSW and North Queensland.
What's Next: The Goyder North Expansion
Coming 2026-2027, Goyder North will add:
1,000+MW wind generation
600MW solar farm
900MW/3,600MWh battery storage
Potential green hydrogen facility
Combined, the Goyder Renewables Zone could power 40% of South Australia during peak periods.
Real Talk: What This Means for Your 2025 Power Bills
The Good News: Increased renewable supply should stabilise or reduce wholesale costs.The Reality Check: Retail prices depend on network charges and retailer margins.The Opportunity: Households with solar+battery can already bypass the grid entirely.
Price Comparison Reality (January 2025):
Wind farm generation cost: $45-55/MWh
New gas plants: $90-110/MWh
Coal power (including maintenance): $100-140/MWh
Nuclear (proposed): $160-230/MWh
Your current retail rate: $290-380/MWh
Smart Money is Moving to Renewables Now
With the Federal Solar Rebate reducing in January 2025 and state incentives changing, smart Aussies are locking in savings before it's too late.
