Fortescue–PLS Pilbara PPA: power security and expansion lens for mine planners
Reviewed by Tom Sullivan

First reported on Australian Mining
30 Second Briefing
PLS has signed a 20‑year power purchase agreement with Fortescue subsidiary FMG Clean Energy to supply at least 325GWh per year of electricity to the Pilgangoora lithium operation in Western Australia, matching the site’s forecast demand under its P2000 operating model. The deal is described as the first large‑scale renewable PPA between two major Pilbara miners and is expected to draw on Fortescue’s planned solar, wind and battery assets. For mine planners, the long‑tenure, fixed‑volume arrangement materially de‑risks power availability for future plant expansions and electrified fleets.
Technical Brief
- PPA tenure of 20 years enables long-horizon mine planning and power integration into life-of-mine studies.
- Agreement is executed via PLS subsidiary Pilgangoora Operation with Fortescue’s FMG Clean Energy unit.
- Firm power commitment supports PLS’ P2000 operating model, underpinning higher-throughput processing and associated load growth.
