Australia’s Ambitious Solar Project to Power Singapore: The Innovations and Challenges


Australia’s ambitious solar power plant project, known as the Australia Asian PowerLink, is poised to become the world’s most powerful solar power plant. The innovative project is designed to cover an area equal to 17,000 football fields with photovoltaic panels for a total capacity of 10 gigawatts. The power produced by the plant will be transferred through Singapore, which is the main consumer of electricity but situated over 3,000 kilometers away from Australia. However, the implementation of this project presents significant challenges, including technical complexity, high costs, and long transmission distances.

Singapore’s Energy Security

Singapore’s government takes energy security seriously by closely monitoring and ensuring adequate energy supplies for businesses and the population. In the early 1990s, Singapore’s energy security was entirely dependent on oil refining from petroleum products, which worsened the environment and caused significant health hazards. As a result, Singapore’s government moved towards an alternative energy source, specifically natural gas. Today, over 96% of Singapore’s electricity is generated from gas, predominantly sourced from pipelines from Malaysia and Indonesia, along with the transportation of liquefied natural gas (LNG) from around the world.

Solar Energy as an Alternative

Singapore has been exploring solar power, given its location in the southern hemisphere, which boasts high levels of solar insulation per square meter. The government’s Solar Nova initiative aimed to increase Singapore’s total solar energy capacity to 350 MW by 2020. Further, the Singapore Energy Market Authority has accelerated the procedure for connecting new solar panels to the grid from 27 to seven days.

However, even with the growth rate of solar energy capacity and increased government support, it still accounts for only 1% of Singapore’s overall electricity needs. Demand for electricity continues to grow in Singapore, with the International Energy Agency indicating that Singapore consumed over 53 billion kilowatt hours last year – a new record in the country’s energy consumption. As such, Singapore needed a solution to the growing crisis.

The Australia-Asian PowerLink

Sun Cable, a technology company in Australia, presented a creative solution to provide Singapore with electricity – one of the world’s largest and most powerful solar power plants. The project comprises three primary components: a solar power plant, a battery complex, and a submarine power cable. The solar power plant will be located near the town of Elliot in North Australia, where photovoltaic panels will cover an area of 12,000 hectares or 17,000 football fields. These panels will be manufactured locally in Darwin to reduce costs and provide job opportunities. The battery complex will have a total capacity of 20 to 30 gigawatts across three sites located in Elliot, Darwin, and Singapore.

Lastly, there will be a two-part transmission line, with the first being a 750-kilometer land line linking the power plant to Darwin, capable of carrying up to 3 GW of electricity. The second part will be a submarine cable extending over 3,700 kilometers to Singapore, where it is expected to supply 2.2 GW of energy and cover nearly 20% of the nation’s electricity needs.

Technical Challenges

The innovative project presents various challenges since it is considered the world’s first prototype. The photovoltaic panels must withstand harsh Australian weather conditions and exchange faulty photovoltaic cells promptly. The battery complex’s storage capacity, sufficient to maintain peak hour demand for electricity, must be affordable, reliable, and feasible. Lastly, the transmission line’s construction presents a significant challenge due to the long distance covered by the submarine cable.

Cost Implications

The entire project costs an estimated $16 billion, potentially making it one of the most expensive energy projects in history. However, Australian billionaires Mike Cannon-Brookes and Andrew Forrest have already offered to invest in the project. The project’s cost is justified given that the energy obtained from it will be one of the cheapest in the world, which will enable Singapore to purchase energy for its needs sustainably.


The Australia Asian PowerLink project is an innovative and ambitious endeavor that aims to solve Singapore’s growing electricity crisis with one of the cheapest sources of energy in the world. The complex project presents unique challenges in its implementation, requiring new technical innovations to make it feasible. Despite its daunting scale, this project represents a change in energy production, reinforcing the idea that renewable energy sources can provide a sustainable future.
