Built to last: How smart asset management extends renewable lifespans
15 June 2025
Powered by the sun
At Stanwell, we’re expanding our energy mix to include firmed renewable energy solutions, and solar plays a vital role. As part of our commitment to delivering affordable, reliable and sustainable energy, we’re investing in large-scale solar projects and long-term power purchase agreements that support Queensland’s future electricity needs. Queensland is one of the sunniest places on Earth, making it ideally suited to solar power. By harnessing the energy of the sun, we’re building a cleaner, more diverse portfolio, while creating jobs and investment in the regions we operate in.
Queensland is a world leader in rooftop solar adoption with the highest household take-up rate in the world.
In 2024, solar power represented 19.6% of Australia’s energy supply, 12.4% was generated by rooftop solar, and a further 7.2% from medium and large scale solar farms according to the Clean Energy Council.
HOW SOLAR POWER WORKS
Solar panels generate electricity using energy from sunlight, a process known as the photovoltaic (PV) effect. Each panel is made up of solar cells, typically composed of silicon, which absorb sunlight and release electrons. These electrons flow through an electrical circuit, creating direct current (DC) electricity. Because most homes and the electricity grid run on alternating current (AC), a device called an inverter is used to convert the DC electricity into AC electricity that can be used immediately or exported to the grid. Of course the sun isn’t always shining making solar a variable energy source. To help maintain a stable and secure energy supply, it must be complemented by firming solutions such as battery storage.
Did you know?
‘Photovoltaic’ comes from the Greek phos, meaning ‘light’, and the volt, the unit of electromotive force named after Italian physicist Alessandro Volta.
Our flagship projects
Solar PPAs
Stanwell has secured a number of long-term power purchase agreements with operational solar farms across Queensland, helping to support the sustainable energy journeys of our commercial and industrial customers. These include:
Blue Grass Solar Farm (49 MW)
Longreach Solar Farm (17.4 MW)
Oakey Solar Farm (25 MW)
Whitsunday Solar Farm (57.5 MW)
Kidston Solar Farm (50 MW)
Scroll for new solar projects being added to the Stanwell portfolio.
Aldoga Solar Farm
The Aldoga Solar Farm is a 380 MW project located near Gladstone in Central Queensland, developed by Acciona Energía.
Under a long-term agreement, Stanwell will purchase 100% of the electricity generated by the solar farm, using it to supply our commercial and industrial customers and support our commitment to affordable, reliable and sustainable energy.

Bulli Creek Solar Farm
Bulli Creek Stage 1 Solar Farm is a 775 MW / 2,234 GWh solar project currently being co-developed by Genex and J-Power. Once operational, it is expected to be the largest grid-connected solar farm in Australia.
Through a 15-year Power Purchase Agreement (PPA), Stanwell will purchase up to 550 MW from the project. Stage 1 forms part of the broader Bulli Creek Clean Energy Park, a multi-stage development planned to deliver up to 2 GW of solar generation and large-scale battery storage.
