Equans Solar & Storage Secures USD 25 Million ARENA Grant to Deploy Robotics and Automation Across Australian Solar Pipeline

ARENA's three-year Lightspeed initiative places Equans Solar & Storage at the centre of a push to drive down the cost of constructing and running large-scale solar farms in Australia, with USD 25 million in federal funding backing trials of up to 10 technologies spanning the full project lifecycle.

Why a Portfolio Model Rather Than Single-Technology Testing

Rather than directing funding toward one technology at a time, ARENA has structured the Lightspeed project around what it describes as a portfolio-style approach, trialling multiple innovations simultaneously across Equans' solar and storage pipeline. The five areas targeted are civil works, mechanical works, electrical works, operations and maintenance, and digital coordination, with the combined aim of reducing the levelised cost of energy for solar photovoltaic projects across Australia. ARENA CEO Darren Miller said bundling multiple trials under a single funding vehicle speeds up the journey from concept to real-world deployment.

"By supporting the trial of multiple innovation projects under a single funding portfolio, we can test technologies more quickly in real-world environments and at a greater scale," he said. "As Australia builds the renewable energy systems needed to support net zero, innovation will play a critical role in reducing costs and improving productivity across the sector." Benoit Froidurot, Innovation and Development Director at Equans Solar & Storage, described the project as a chance to pioneer technologies relevant to both construction and ongoing operations.

"Robotics supported by digital and AI will contribute to ensuring the volume of renewable assets needed can be met. It can help achieve cost reduction and assist with overcoming some of the grid integration restrictions of solar energy," Froidurot said. He also cited the potential to scale up the use of automated machines and systems across the sector more broadly.

Autonomous Inspection Robot to Make Its Australian Debut

The first technology scheduled for deployment under Lightspeed is the Nextpower Ranger, an autonomous inspection robot. ARENA confirmed this will represent the Ranger's first trial at an Australian solar farm, with the exercise designed to demonstrate its practical benefits and build market confidence in the technology. Construction robotics and automated piling systems are also within the project's scope. These technologies are aimed at reducing labour-intensive activities on site, improving construction efficiency, increasing productivity, and enhancing project delivery timelines across solar developments.

Fortescue's Pilbara Hub Provides the Blueprint

The Lightspeed project draws directly from a model already in operation through Fortescue's Pilbara Solar Innovation Hub, which is trialling solar innovations across Fortescue's Pilbara sites. That hub has produced its first milestone report alongside a dedicated Built Robotics trial report, documenting insights from the trial of autonomous piling technology at the Cloudbreak Solar Farm under remote Pilbara conditions.

ARENA said the Equans initiative builds on that model, with the intention of making learnings from the Lightspeed project available to the wider industry. The agency's aim is to accelerate the adoption of technologies that prove effective in real operating environments, rather than limiting the benefits to the individual project in which they are first tested.

Commercially Relevant Data Over Laboratory Results

The three-year timeframe has been set to allow rigorous testing across real operating conditions, covering the full project lifecycle from construction through to operations and maintenance. By embedding the trials within Equans' existing pipeline of solar and storage projects, ARENA intends the initiative to generate commercially relevant data rather than findings from controlled or laboratory settings. The funding sits within ARENA's broader focus on ultra-low-cost solar, which the agency has identified as a priority area as Australia works to scale renewable energy deployment.

Miller said finding new ways to lower the cost of building and operating renewable energy projects will be essential as the sector expands. "This approach allows promising innovations to move from concept to real-world deployment faster, while ensuring lessons learned can be shared across the industry," he said. The announcement points to a widening focus within Australia's renewable energy sector on the economics underpinning deployment, not just the pace of it.

With targets aligned to net zero driving demand for utility-scale solar infrastructure, the cost of constructing and maintaining that infrastructure remains a central variable. ARENA's direction of funding toward automation and digitisation reflects an agency view that structural shifts in those cost curves are achievable through the kind of technology trials the Lightspeed project is designed to produce.
