Monadelphous Wins $120M in Four New Contracts With Rio Tinto and Fortescue
Monadelphous lands ~$120 million in new contracts with Rio Tinto, Fortescue and Port Waratah
Monadelphous Group Limited (ASX: MND) has announced new construction and maintenance contracts valued at approximately $120 million in aggregate, spanning the resources and renewable energy sectors. The update covers four separate awards across three blue-chip clients: two contracts with Rio Tinto, one battery energy storage system (BESS) construction contract with Fortescue at its Cloudbreak mine site, and a panel appointment with Port Waratah Coal Services at the Port of Newcastle in New South Wales.
The breadth of the announcement reinforces Monadelphous’ position as a preferred contractor across both its traditional resources base and the growing renewable energy transition workstream.

Breaking down the four contract wins
The four contracts span a range of service types, durations and geographies, with individual values not disclosed beyond the aggregate figure.
Rio Tinto — five-year panel contract: mobile crane and lifting services
Monadelphous has secured a new five-year panel contract to provide mobile crane and lifting services across Rio Tinto’s Pilbara port and mine facilities. As a panel arrangement, the contract provides a framework for ongoing work orders to be issued over the term rather than committing to a single defined project scope.
Rio Tinto — three-year contract: multidisciplinary sustaining capital services
The company has also secured a three-year contract to continue providing Rio Tinto with multidisciplinary sustaining capital services. The use of “continue” in the announcement indicates this represents a renewal or extension of an existing relationship with the client.
Fortescue Cloudbreak — BESS construction at Cloudbreak mine site, Pilbara
Monadelphous has been awarded a contract for the construction of a battery energy storage system (BESS) at Fortescue’s Cloudbreak mine site in the Pilbara, Western Australia. This marks the company’s third BESS project supporting Fortescue’s decarbonisation programme. Work is expected to be completed in the second half of 2026.
Port Waratah Coal Services — three-year panel appointment at Port of Newcastle
Monadelphous has been appointed to a panel for a term of three years to provide structural and mechanical maintenance services for Port Waratah Coal Services at the Port of Newcastle, New South Wales.
| Client | Contract Type | Duration | Location | Sector |
|---|---|---|---|---|
| Rio Tinto | Panel contract — mobile crane and lifting services | 5 years | Pilbara, WA | Resources |
| Rio Tinto | Multidisciplinary sustaining capital services | 3 years | Pilbara, WA | Resources |
| Fortescue | BESS construction | Project-based (completion H2 2026) | Cloudbreak, Pilbara, WA | Renewable Energy |
| Port Waratah Coal Services | Panel appointment — structural and mechanical maintenance services | 3 years | Port of Newcastle, NSW | Resources / Infrastructure |
What is a BESS, and why does Monadelphous’ third project for Fortescue matter?
A battery energy storage system (BESS) is a large-scale installation that stores electrical energy in batteries for later use. In a mining context, BESS units are typically deployed alongside solar or wind generation to reduce reliance on diesel-powered generation, lowering both fuel costs and carbon emissions across remote mine sites.
For operations like Fortescue’s Cloudbreak mine in the Pilbara, which operates far from the electricity grid, diesel has historically been the primary power source. Integrating BESS technology allows the site to shift toward cleaner and potentially lower-cost energy, supporting Fortescue’s stated commitment to decarbonising its operations.
For investors assessing Monadelphous, the significance of this contract extends beyond its individual value. Being awarded a third BESS project for the same client suggests the company has demonstrated a repeatable, proven capability in this space. Repeat appointments of this nature are generally indicative of preferred-contractor status, where a client returns to the same provider rather than retendering broadly.
Renewable energy construction remains a smaller component of Monadelphous’ overall revenue mix compared to its resources work, but the accumulation of BESS projects represents a measured expansion into a sector with a longer-term structural growth profile.

Reinforcing the investment case — long-duration panels and repeat clients
Two of the four contracts awarded are panel arrangements, spanning five years and three years respectively. Panel contracts differ from one-off project awards in that they establish a standing relationship through which work orders are issued progressively over the term. This structure provides greater revenue visibility and reduces the need to re-compete for each individual task.
The geographic spread across the Pilbara in Western Australia and the Port of Newcastle in New South Wales also reflects the diversity of Monadelphous’ operational footprint. The client roster, comprising Rio Tinto, Fortescue, and Port Waratah Coal Services, represents some of the largest operators in Australian resources and port infrastructure.
Key highlights from the announcement at a glance:
- Aggregate contract value of approximately $120 million
- 4 contracts across 3 clients
- 2 panel contracts (five-year and three-year terms)
- 3rd BESS project awarded by Fortescue to Monadelphous
- BESS construction expected to be completed in H2 2026
- Geographic reach: Pilbara, WA and Port of Newcastle, NSW
