The company aims to develop this system as a replicable and commercially scalable model that can be deployed in different regions.
Fortescue is particularly focused on eliminating the use of imported diesel fuel, which is highly exposed to price volatility. Through this transition, the company plans to both reduce cost pressures and strengthen energy supply security.
Unlike traditional grid systems, Fortescue’s model is designed as an off-grid, fully integrated structure capable of delivering 24/7 renewable energy to large-scale industrial operations.
The company targets commissioning 290 MW of renewable energy capacity in early next year at its Pilbara operations to meet the fixed energy demand of its ore processing facilities. This capacity will enable “green processing” during daytime hours, with full round-the-clock fossil-free operations planned later in the year.
Fortescue had previously set its “Real Zero” target for December 2030. However, the company now expects the Pilbara green grid to be fully completed by the end of 2028, effectively bringing the target forward. The plan includes 1.2 GW of solar capacity, over 600 MW of wind power, and 4–5 GWh of battery storage.
Highlighting volatility in global energy supply chains and the risks of fossil fuel dependency, Fortescue emphasized that large-scale industry can become energy self-sufficient through renewables, while also achieving more predictable energy costs.
