Australia’s biggest power supplier, AGL, is proposing to build a solar-and-hydro energy facility at the site of its Liddell coal-fired power station in NSW once the plant closes down in 2023.
AGL has been collaborating with Melbourne-based developer RayGen on an Australian-first “concentrated solar thermal” project, which uses a field of rotational mirrors to capture sunlight and stores the energy in water reservoirs. As more coal power exits the market in coming years, advocates of the technology say it could be an alternative to gas and big batteries in supporting renewable energy uptake.
