Publicly anti-renewables except for herself and Gina
Gina Rinehart's company, Hancock Prospecting, has installed solar and battery systems at its Pilbara mines for dewatering operations, saving diesel and achieving 55% RENEWABLE energy penetration at those sites.
..
The company has also planned a 30 MW solar farm for its Mulga Downs mine, and Rinehart has a significant investment in the Kathleen Valley lithium mine, which runs on 81% RENEWABLES (wind, solar, and battery).
.
These projects highlight a strategic move towards renewable energy for economic savings at remote mine sites, despite Rinehart's public opposition to net zero policies.
.
Hancock Prospecting mining operations
Pilbara mines: Three solar and battery hybrid systems have been installed for dewatering, combining 750 kW of solar PV and 1.68 MWh of battery storage.
.
Renewable penetration: These systems are designed to achieve 55% renewable energy penetration at the remote, off-grid sites, resulting in ANNUAL SAVINGS of up to 250,000 liters of diesel.
.
Future plans: Hancock Prospecting has applied to build a 40 MW solar facility at its Mulga Downs mine.
Kathleen Valley lithium mine
Rinehart's role: Rinehart is a major shareholder in the project, which is operated by Liontown Resources.
.
Renewable power: The mine has a hybrid power station with 30 MW of wind, 17 MW of solar, and a 17 MW/19 MWh battery, which achieved an 81% average penetration of renewables in the 2025 fiscal year.
