Malaysian engineering and infrastructure giant Gamuda has partnered with landowners for a 1.2GW renewable energy and energy storage portfolio in Tasmania, Australia, which includes up to 600MW of energy storage capacity.

This portfolio will include around 600MW of solar PV and wind generation and up to 600MW of battery energy storage systems (BESS).

Through its Australian subsidiary, Gamuda Holdings, the company has partnered with the Downie Family and its development partner Alternate Path, an energy consultancy based in Victoria, to help develop the 250MW Weasel solar-plus-storage site and the 350MW Cellars Hill wind-plus-storage site in Tasmania.

Weasel solar-plus-storage project in Tasmania

The Weasel solar PV power plant is being developed 9km north of Bothwell in the centre of Tasmania, near the River Clyde.

It will connect to the National Electricity Market (NEM) and be located within the T3 Tasmania Midlands proposed Renewable Energy Zone (REZ).

The Australian government recently approved the project after it was submitted to the Environment Protection and Biodiversity Conservation (EPBC) Act in April 2025. Notably, the approval process was completed in just 20 days.

The solar PV power plant will feature up to 4,000 single-axis tracking PV modules installed over 270 hectares of land. The layout will allow for the continuation of agricultural practices, primarily sheep grazing, in a site use combination known as ‘agrivoltaics.’

Additionally, the solar-plus-storage site will include a co-located BESS with a capacity of 144MW/576MWh, occupying a 3-hectare area.

Cellars Hill wind-plus-storage project

The 350MW Cellars Hill wind-plus-storage site is an AU$1.5 billion (US$940 million) proposal that was granted ‘Major Project’ status by the Tasmanian government in February 2025.

The wind project includes plans for a 600MW/2,400MWh BESS to be co-located on the project site.

Gamuda has confirmed its support for the development of 600MW of BESS in Tasmania. However, with the combined total of the two projects amounting to 744MW, it remains unclear which projects will see their respective BESS downsized or scrapped.

PV Tech has contacted Gamuda about the new BESS sizes but has not received a response at the time of publishing.

Subject to further planning and development processes, construction of the Weasel solar PV plant is estimated to commence in 2027, with the Cellars Hill project following in 2028.

Earlier this year, Gamuda and infrastructure developer Ferrovial signed an early contractor involvement (ECI) to develop the 750MW/12GWh Capricornia pumped hydro project in Queensland.

The project is being explored approximately 80km west of Mackay, central Queensland, on two large rural landholdings near the existing Eungella Dam.
