Revolutionizing Solar Projects with Autonomous Machines
Neoen is not the only renewables developer exploring the use of robots; the contractor at Engie’s Goorambat East solar farm is also testing autonomous machines, this time for pile driving.
The Build Robotics device commenced operations in February and completed the installation of 1700 piles by mid-April. It received $1.3 million in funding from the Australian Renewable Energy Agency (ARENA) in November to refine the system.
Autonomous Pile-Driving Process
The prototype, developed by Bouygues Construction Australia, is currently slower than human labour but offers a much quieter alternative to the traditional method of pile installation, according to project director Bastien Sauvet. The autonomous machines utilise AI, GPS, and sensor technology to accurately drive piles with minimal human intervention. They can automatically shut off if a human enters a designated area to prevent accidents.
One notable feature is the use of vibrating piles into the ground instead of hammering, resulting in a 20 per cent reduction in noise levels. This innovation not only benefits the environment but also ensures the safety and well-being of nearby workers.
Future Applications and Challenges
Renewables developers are considering the use of autonomous machines for larger projects in remote and harsh environments where human labour may be impractical. Projects like the Gurambat East solar farm in Victoria, though significant at 250 megawatts, are dwarfed by proposed wind farms and larger solar installations.
Companies like Neoen and Engie are aiming to construct projects on a much grander scale, reaching up to 800MW. However, the reliance on human labour for certain tasks, such as lifting modules and installing piles, poses challenges in meeting labour regulations and project timelines.
As the industry contemplates the use of robots in desert regions like the Pilbara and Saudi Arabia, concerns arise regarding the safety and feasibility of extended human work periods in such environments. The shift towards automation raises questions about job displacement and the need for upskilling the existing workforce to operate robotic equipment.
Impact on Jobs and Efficiency
While the introduction of autonomous machines may lead to concerns about job losses, proponents argue that these technologies can enhance productivity, reduce project costs, and ultimately benefit consumers by lowering energy prices. Engie’s Leigh Newbery emphasises that skilled technicians are required to operate these robots, leading to upskilling within the renewable energy sector.
Build Robotics, the recipient of the ARENA grant, envisions a future where humans work alongside robots, necessitating a workforce with advanced skill sets to manage and maintain the technology. The company aims to train individuals to operate robotic equipment efficiently, ensuring a smooth transition towards automation.
As the renewable energy sector embraces technological advancements, the role of humans in project development and maintenance evolves, paving the way for a more efficient and sustainable future.
