Broome, a remote town in Western Australia’s outback, is restarting its 10MW solar farm project after its first attempt—abandoned in 2021 due to cost overruns and feasibility concerns—failed to secure funding. The new push, backed by a $45 million state grant and a 20-year power purchase agreement (PPA) with EnergyAustralia (ASX: EAU), aims to deliver 15% of Broome’s annual electricity needs by 2028. Here’s why this matters: Australia’s National Electricity Market (NEM) is under pressure to replace retiring coal plants, and Broome’s project could set a precedent for remote renewables financing in a region where grid connections cost $50 million per 100km.
The Bottom Line
- Broome’s solar farm could slash the town’s diesel dependence by 30,000 liters annually, cutting emissions and operational costs for EnergyAustralia (ASX: EAU) by $1.2 million over the PPA term.
- The project’s success hinges on whether the state’s $45M grant covers the remaining $80M funding gap, a risk amplified by Western Australia’s 2026 budget deficit of $3.1B.
- If replicated, similar deals could unlock $2.4B in stranded renewables projects across Australia’s remote regions, according to the Australian Energy Market Operator (AEMO).
Why Broome’s Solar Gamble Could Reshape Remote Energy Markets
Broome’s first solar attempt collapsed in 2021 when the developer, SunOutback (now defunct), walked away after securing only $30M of the $120M required. The project’s economics were always fragile: diesel-generated power in Broome costs $0.35/kWh, while solar with storage would deliver it at $0.18/kWh—yet transmission costs alone would have added $0.12/kWh to the final price. This time, the state government is underwriting the risk, but the math remains tight.
Here’s the balance sheet: The $45M grant covers 56% of the project’s $80M shortfall, leaving a $35M funding hole. EnergyAustralia (ASX: EAU)’s PPA guarantees 90% capacity factor, but the remaining gap may require private equity or green bonds. Comparatively, Neoen’s (ASX: NEO) 150MW Sun Cable project in the Northern Territory secured $600M in debt financing—Broome’s scale is 1/15th the size, but its remoteness makes financing harder.

“This is a litmus test for how Australia funds renewables in Tier 3 towns—places where grid connections are prohibitively expensive. If Broome’s model works, we could see a 30% uptick in remote solar projects by 2029.”
How the Project Affects EnergyAustralia (ASX: EAU) and the NEM
EnergyAustralia (ASX: EAU)’s decision to lock in a 20-year PPA reflects its strategy to hedge against carbon pricing and volatile wholesale markets. The PPA’s $0.15/kWh strike price is 12% below Broome’s current diesel cost, but it’s 30% above EnergyAustralia’s (ASX: EAU) average renewable procurement cost of $0.11/kWh in the NEM. Analysts at UBS (NYSE: UBS) note this could pressure EAU’s (ASX: EAU) margins by 2-3% unless offset by higher retail prices—a risk in a state where household energy bills are already 18% above the national average.
The broader impact on the NEM is mixed. On one hand, Broome’s project aligns with the AEMO’s 2026 Integrated System Plan, which targets 82% renewables penetration by 2030. On the other, remote solar farms like this one contribute little to grid stability compared to large-scale wind or hydro. AEMO’s latest data shows that 92% of Australia’s renewable capacity is concentrated in the NEM’s southeast corner—leaving the northwest, where Broome sits, with just 2% of the country’s solar capacity despite having 300 days of sunshine annually.
| Metric | Broome Solar Farm (2028) | Neoen’s Sun Cable (2026) | WA State Avg. (2025) |
|---|---|---|---|
| Capacity (MW) | 10 | 150 | N/A (Grid-dependent) |
| LCOE ($/kWh) | 0.18 | 0.12 | 0.15 |
| Funding Gap (% of total cost) | 44% | 20% | N/A |
| Diesel Displacement (liters/year) | 30,000 | N/A | N/A |
What Happens If the Funding Gap Isn’t Filled?
The project’s viability hinges on three variables: the state’s ability to deliver the $45M grant on time, private sector appetite for the remaining $35M, and whether EnergyAustralia (ASX: EAU) can renegotiate the PPA terms. If the grant is delayed—Western Australia’s 2026 budget includes $1.2B in deferred infrastructure payments—the project could stall again, forcing Broome to revert to diesel generation. This would increase the town’s carbon footprint by 12,000 tons annually and raise electricity costs for residents by 8%.
Alternatively, if the project succeeds, it could attract Macquarie Group (ASX: MQG) or Infrastructure Capital Group (ASX: ICL) to underwrite similar deals in Karratha (ASX: KTA) or Port Hedland, where diesel costs exceed $0.40/kWh. MQG’s 2025 renewable energy report highlights that 68% of Australia’s remote communities lack access to firm renewable power, creating a $5B market opportunity.

“Broome’s solar farm is a microcosm of Australia’s energy duality: we’re world leaders in large-scale renewables but lag in decentralized, remote solutions. The real question isn’t whether this project will work—it’s whether policymakers will treat it as a pilot or a precedent.”
The Bigger Picture: How This Affects Australia’s Renewables Transition
Australia’s renewables rollout has been uneven. While Tesla (NASDAQ: TSLA)’s Hornsdale Power Reserve and Neoen’s (ASX: NEO) 250MW Stockton solar farm dominate headlines, remote towns like Broome remain energy islands. The Australian Energy Regulator (AER) estimates that 30% of Australia’s off-grid communities rely on diesel, contributing 5% of the country’s emissions—a figure that could shrink if Broome’s model scales.
Yet challenges remain. The AEMO’s 2026 Transmission Investment Roadmap identifies 1,200km of new grid connections needed to link remote renewables to the NEM, at a cost of $3.8B. Without federal subsidies, projects like Broome’s will struggle to compete with cheaper coal or gas in the short term. EnergyAustralia (ASX: EAU)’s CEO, Catherine Tanna, has signaled support for federal intervention, but the Liberal-National Coalition’s 2026 energy policy remains vague on remote renewables funding.
What’s Next for Broome—and Australia’s Renewables Future?
The next 12 months will determine whether Broome’s solar farm becomes a blueprint or a cautionary tale. Key milestones include:
- The Western Australian government’s approval of the $45M grant by Q4 2026 (due for budget lock-in in October).
- EnergyAustralia (ASX: EAU)’s finalization of the PPA terms, expected by March 2027.
- The Australian federal government’s response to the AEMO’s 2027 Integrated System Plan, which may include remote renewables incentives.
If successful, Broome’s project could accelerate the retirement of EnergyAustralia (ASX: EAU)’s Collie coal plant (due to close in 2030) by proving that remote solar can replace baseload generation. If it fails, it risks setting back Australia’s renewables timeline by 2-3 years in off-grid regions.
