Redeployable Hybrid Power


  • Solar panels at completed 1MW solar-diesel hybrid plant

  • Completed 1MW solar-diesel hybrid plant at Laing O’Rourke accommodation village near Roma

  • Easy, rapid and safe on-site assembly of the solar modules. Excavators may be used for driving in screw-piles and placing the solar modules.

  • A semi-trailer compactly transports 72 solar modules from storage depot to site for deployment. Each module integrates wiring, framing, structure and PV panels.

  • One of the four prototype solar modules fabricated by Redispan, showing two PV panels inclined and one PV panel stowed. L-R: Michael Read and John Mackenzie.

  • Inverter installation

  • Solar module deployment

  • Installation complete

This project involves a pilot-scale deployment of a fully redeployable hybrid solar/diesel power plant. Laing O’Rourke will construct, set up and pack down a demonstration solar plant. The technology has the potential to change the  renewable energy landscape in regional and remote Australia.

Many remote Australian communities rely on diesel generators that are expensive to run and are subject to energy uncertainty due to the volatility of fuel prices. Having to transport the fuels long distances is also costly, dangerous and subject to variable weather conditions.

Mobilising solar photovoltaics in these remote environments is currently complex and expensive. This is because solar farms are traditionally constructed on-site from thousands of components. There is a need for a different approach to solar farm construction, that realises the benefits of modularisation and off-site manufacture.

Project innovation

Laing O’Rourke is an engineering enterprise engaged in Design for Manufacture and Assembly (DfMA), digital engineering and innovation. The company has developed a redeployable hybrid power plant (patent pending) to address the market’s need for cheaper off-grid electricity. Each plant consists of a DfMA solar photovoltaic farm, a containerised integration module and traditional diesel generators.

Laing O’Rourke has applied its expertise to the design of solar farms. Modules that integrate multiple solar panels, framing, associated wiring and inverters are manufactured off-site, transported, and safely assembled on-site. At the end of the project, the solar farm can be easily packed up and taken to the next deployment.

This project involves advancing the redeployable hybrid plant through detailed design and prototyping to provide a technical solution ready for deployment in the Austraian market.


Renewable energy can reduce the reliance of regional communities and industries on expensive, trucked-in diesel.

Off-site construction and rapid pack-up and pack-down have the potential to lower costs and reduce risks associated with undertaking projects in regional and remote Australia. The permanent and long term nature of solar installations is a key barrier to their use off-grid, particularly in mining operations.

Each redeployable hybrid plant will power multiple successive off-grid users, allowing users to benefit from the advantages of solar without committing to a permanent installation.
