Frontier Energy Locks in All Major Contracts for $310M Waroona Solar-BESS Build
Key Takeaways
- Frontier Energy has executed all major fixed-price equipment and construction contracts for Waroona Stage One, covering the majority of the $310 million project budget with a $22 million contingency fully funded.
- Two EPC contractors anchor the build: Monford Group for solar-BESS construction and commissioning, and Global Power Services for substation works, with site works commencing September 2026.
- Tier-one global suppliers are contracted across every critical system — LONGi (world's largest PV manufacturer), Trina Storage (top-10 BESS, 20-year warranty), SMA Australia (top-three inverter manufacturer), and Nextpower LLC for solar tracking.
- The Western Power grid connection is unconditional, with the ETAC and IWC executed, enabling export of up to 99MW and import of up to 95MW to charge the BESS — a critical de-risking milestone for any utility-scale renewable project.
- Only 300 of 830 hectares of grid-adjacent freehold land are committed to Stage One, with Stage Two already being advanced, signalling a materially larger long-term asset platform.
Frontier Energy locks in all major contracts for Waroona Stage One
Frontier Energy (ASX: FHE) has executed all major equipment and construction contracts for Stage One of its Waroona Renewable Energy Project, marking a significant de-risking milestone for the 132MW solar facility paired with an 81.5MW / 6.9-hour battery energy storage system (BESS). Fixed-price contracts now form the majority of the $310 million project budget, which, together with a $22 million contingency, is fully funded. Site works are scheduled to commence September 2026, with first generation targeted for 2028.

Q1 FY27 milestone: what’s been locked in
Fixed-price contracts matter because they remove the two biggest risks in any large infrastructure project: cost blowout and execution uncertainty. With all major contracts now executed in line with the company’s guidance, Frontier has substantially reduced both.
Two EPC contractors anchor the construction programme. Monford Group will handle construction and commissioning of the solar-BESS facility, while Global Power Services will deliver the substation works. Alongside these, Frontier has secured a suite of tier-one global equipment suppliers:
- LONGi (world’s largest PV panel manufacturer) — over 200,000 panels at 650W/655W capacity, first delivery scheduled January 2027
- Trina Storage (top-10 global BESS supplier) — includes a 20-year warranty and long-term services agreement
- Nextpower LLC (international leader in solar tracking systems) — first delivery scheduled November 2026
- SMA Australia (top-three global inverter manufacturer) — converting DC solar output to AC for grid export
The Western Power connection is now unconditional. Frontier’s Electricity Transfer Access Contract (ETAC) and Interconnection Works Contract (IWC) enable export of up to 99MW into the network at the nearby Landwehr Terminal and import of up to 95MW to charge the BESS when solar generation is low. Long-lead interconnection items have been procured, the tender process for construction is well advanced, and factory testing of the connecting cable has been successfully completed.
| Supplier / Contractor | Role | Global Ranking | Key Detail | Timeline |
|---|---|---|---|---|
| Monford Group | EPC — solar-BESS construction & commissioning | — | Free-issue model; takes delivery at Fremantle Port | Site works from Sep 2026 |
| Global Power Services | EPC — substation works | — | Fixed-price contract executed | Site works from Sep 2026 |
| LONGi | PV panels | World’s largest PV manufacturer | 200,000+ panels, 650W/655W capacity | First delivery Jan 2027 |
| Trina Storage | BESS supply | Top-10 global BESS supplier | 20-year warranty + long-term services agreement | — |
| Nextpower LLC | Solar tracking systems | International industry leader | North-south axis tracking to follow sun’s path | First delivery Nov 2026 |
| SMA Australia | Inverters | Top-three global inverter manufacturer | DC to AC conversion for grid export | — |
Why the free-issue contracting model matters for investors
Under a “free-issue” model, Frontier purchases equipment directly from manufacturers and then hands it to Monford for installation, rather than having Monford procure everything and clip the margin along the way. The company has stated four specific advantages of this approach:
- Direct control over equipment selection
- Long-term relationships with tier-one suppliers across the 30-year project life
- Lower EPC contract value and reduced contractor margins
- Immediate ownership of equipment from the outset
What this means in practice is a lower overall cost structure and stronger relationships with the suppliers whose technology will be generating revenue for three decades. Monford takes delivery at Fremantle Port and manages all logistics through to installation and commissioning, which keeps the handoff clean and accountability clear.
For investors assessing execution risk, the free-issue model is a meaningful distinction. It puts Frontier in the driver’s seat on the project’s largest cost inputs rather than outsourcing that control to a contractor with different commercial incentives.

Fully funded, fully contracted — what comes next
The headline investor takeaway from this announcement is straightforward: Frontier is fully funded and fully contracted for Waroona Stage One.
Executive Chairman Jamie Cullen
“This is a defining milestone for Frontier. We have now secured the full suite of contracts required to deliver Stage One at our Waroona Project and position the Company as Western Australia’s largest solar-BESS hybrid power producer.”
Site works are scheduled to commence this month, September 2026, supported by the recently completed capital raising and credit-approved commitments for debt finance. First generation is targeted for 2028.
Beyond Stage One, the scale of Frontier’s land position signals meaningful expansion potential. Only 300 of 830 hectares of grid-adjacent freehold land are committed to Stage One, and the company has stated the team is already advancing Stage Two.
The broader WA energy context reinforces why this project carries strategic weight. The state needs new generation capacity to support the targeted retirement of ageing fossil fuel plants while meeting rising demand from data centres and continued population growth. A 132MW solar facility paired with 81.5MW of dispatchable battery storage is the kind of asset that fits directly into that gap.
As Cullen noted in his statement: “Stage One is our first step in delivering exactly that. We look forward to the commencement of site works this month.”
With contracts executed, funding in place, and site works beginning, Frontier moves from development to construction. The de-risking work is done. The build begins now.
