Western Australia is famous for quite a few things. It is the biggest state of Australia, home to quokkas (the world’s happiest animal), and the longest coastline. They also have abundant mineral wealth and recently unveiled the ‘Mother of all energy plants’. This energy plant will be bigger than 47 countries, and you can see it from space – crickey! It is not surprising that this ‘Mother of all energy plants’ aims to be a global green hydrogen leader.
Western Australia is planning the ‘Mother of all energy plants’
When we say the biggest state in Australia will have the biggest of all energy plants, we mean it! A corporate trust consisting of CWP Global, InterContinental Energy, and Mirning Green Energy submitted an application to Western Australia’s Environmental Protection Authority (EPA) for a diverging energy plant. The plant, known as Western Green Energy Hub (WGEH), is on the verge of transforming the region’s energy landscape and Australia’s position in global green hydrogen production. The project will cost an estimated cost of AUD 100 billion (US$ 65 billion).
WGEH will be built on pastoral leases and crown lands in Mirning Country. It will boast up to 3,000 wind turbines with a power output of up to 20 MW each and 35 solar PV plants with 6 million solar panels. The wide range of renewable energy sources will supply power to the centrally located electrolyzer, producing nearly 3.5 million tonnes of green hydrogen annually and 330 kt of green hydrogen in the initial phase.
As soon as the plant is in full swing, it will produce approximately 200 TWh of renewable energy annually, which could match Australia’s current total energy production. The plant’s green hydrogen will be used domestically and internationally. It will supply power production, shipping fuel, minerals processing, and manufacturing industries. Most of the output will be exported as green ammonia.
This is why the ‘Mother of all energy plants’ will be beneficial
WGEH’s project developers improved their key position after signing a collaboration agreement with Korea Electric Power Corporation (KEPCO). The collaboration highlights WGEH’s international appeal and global interest in enhancing sustainable energy solutions. Together, they are conducting a comprehensive feasibility study to refine the development plans for the initial stages of the project.
The plant will technologically advance renewable energy and promote the region’s major economic development. WGEH aims to significantly reduce global carbon emissions by harnessing Western Australia’s vast renewable energy sources, aligning with international goals of a sustainable future.
The project promises a more sustainable future and will enhance major job creation. WGEH will create fundamental reserve facilities, such as data centers, workshops, and a workers’ village that will accommodate up to 8,000 residents. Coastal and offshore facilities will sport a marine offloading facility, a desalination plant, and pipelines for ammonia or other export vectors.
The massive energy plant’s predicted timeline
This promising project, with all its potential benefits, was under review by the Australian government’s Environment Protection and Biodiversity Conservation (EPBC) Act, which contains regulations to protect endangered species and ecological communities. Per official documents, the Australian Government started accepting public feedback on February 7, 2025.
We could be waiting longer than expected, though, as the project will be developed in seven stages and construction is said to take place over 30 years. The project aims to initiate construction by 2029, with the first production phase expected in 2032. The initial phase will generate a whopping 50 GW of renewable energy.
The massive 70 GW renewable energy and green hydrogen production facility in Western Australia marks an essential step toward large-scale renewable energy production, progressing the global transition to renewable energy solutions. The land down under has certainly made its mark on the future of sustainability, and we cannot wait to see the finished project in all its glory.
