Powering the Future: AGL’s Landmark Microgrid Transforms Agricultural Energy at Koompartu Farms

In a significant advancement for sustainable agribusiness, energy giant AGL has unveiled a pioneering microgrid project at Koompartu Farms, a sprawling 9,340-hectare almond orchard in South Australia. This state-of-the-art infrastructure, developed for US-based private equity firm RRG Capital Management, represents a paradigm shift in how large-scale industrial operations manage energy security, environmental impact, and grid connectivity.

By integrating localized solar generation with advanced battery storage and a bespoke distribution network, the Koompartu project serves as a blueprint for the future of off-grid and semi-grid-connected commercial energy.

The Core Infrastructure: Engineering Scale and Complexity

The Koompartu microgrid is not merely a solar installation; it is a sophisticated energy ecosystem designed to sustain one of Australia’s most intensive agricultural sites. The system connects to the SA Power Networks distribution network at 11kV, functioning as a hybrid utility that augments grid supply precisely when network capacity is strained by the orchard’s peak irrigation demands.

The sheer scale of the project is reflected in its infrastructure: the site features a 19km underground high-voltage network, a technical necessity for transmitting power across such an expansive property. To manage this, AGL partnered with TGOOD Australia, which supplied 11 interconnected substation kiosks. These units, featuring unique configurations, are designed to orchestrate complex load flows, ensuring that power is distributed efficiently across the property regardless of the source.

By assuming the role of builder, owner, and operator under a 20-year Power Purchase Agreement (PPA), AGL has effectively decoupled energy management from agricultural production. This allows the Koompartu management team to focus exclusively on their horticultural operations, offloading the technical burdens of energy reliability and asset maintenance to AGL’s sustainable business energy solutions division.

Chronology of a Sustainable Shift

The Koompartu project is the latest and largest in a strategic series of agricultural microgrid developments spearheaded by AGL across South Australia and New South Wales. This trajectory demonstrates a growing corporate commitment to "behind-the-meter" energy solutions.

• 2023: RRG Capital Management initiates the development of its South Australian almond portfolio, spanning over 2,500 hectares of plantings, setting the stage for the Koompartu energy requirements.
• Early 2024: AGL accelerates its focus on agricultural microgrids, leveraging its experience in renewable integration to design the Koompartu system.
• May 2024: AGL successfully commissions a 4.8MW solar and 4.2MWh battery microgrid at Cadell Orchards in the NSW Riverina for Australian Farming Services. This project successfully reduced the orchard’s diesel dependence by 85% and cut annual carbon emissions by approximately 4,700 tonnes.
• Mid-2024: AGL deploys a 6.5MW solar and 5.1MWh battery storage system at the Canally Almond Orchard, utilizing the same long-term PPA model that would later be scaled for Koompartu.
• 2025: AGL acquires Tesla’s South Australian Virtual Power Plant (VPP), signaling the company’s intent to lead the market in distributed energy resource (DER) coordination.
• Late 2025 – Present: The Koompartu microgrid reaches operational status, marking the largest deployment in AGL’s agricultural portfolio to date.

Supporting Data: Efficiency and Emission Reductions

The shift away from legacy energy sources is the primary driver for these investments. At Koompartu, the reliance on diesel-powered generators—traditionally the backbone of remote agricultural irrigation—is expected to plummet by 88%. This reduction is not only a victory for the environment but also a strategic hedge against the volatility of global diesel prices.

The data from previous projects illustrates the tangible benefits of this model:

• Emission Mitigation: At Cadell Orchards, the move to solar-battery hybrids resulted in a reduction of 4,700 tonnes of CO2 per year. Koompartu, being significantly larger in footprint and energy demand, is expected to yield even higher abatement figures, contributing substantially to the sector’s broader ESG (Environmental, Social, and Governance) targets.
• Resilience Metrics: By utilizing battery storage to "buffer" the grid, these systems ensure that irrigation pumps—which are critical to crop survival—maintain constant power during grid outages or voltage fluctuations.

The infrastructure complexity, characterized by the 19km underground network, ensures that the system is resilient against environmental hazards such as bushfires, which have historically threatened overhead power lines in regional Australia.

Official Responses and Strategic Implications

Brendan Weinart, AGL’s General Manager of Sustainable Business Energy Solutions, highlighted the project’s significance during the unveiling.

"This is a first-of-its-kind project and has been designed to improve local grid capacity and provide the reliability needed to keep critical irrigation systems operating," Weinart stated. "With diesel genset usage expected to fall by 88%, the project shows the role tailored microgrid solutions can play in helping businesses reduce emissions and improve resilience."

For large-scale agribusinesses, the message is clear: energy is no longer a peripheral utility cost; it is a core operational asset. By embracing microgrids, companies like RRG Capital Management are insulating their production cycles from the unpredictability of remote grid supply while simultaneously achieving a smaller carbon footprint.

Microgrids as a Growing Market Opportunity

The Koompartu project sits at the vanguard of a national transition toward distributed energy infrastructure. For many commercial and industrial (C&I) customers, accessing grid-scale renewables is often hindered by geographical isolation or network congestion. Consequently, "behind-the-meter" generation is emerging as the most commercially viable path to decarbonization.

The Role of ARENA and Government Support

The Australian Renewable Energy Agency (ARENA) has played a pivotal role in this landscape. Since 2023, ARENA has provided targeted funding to support microgrid deployment, recognizing that remote operations face unique access constraints.

Beyond agriculture, this model is gaining traction in community resilience. Recent funding allocations, such as the AU$3 million granted to EDP for a bushfire-resilient microgrid, demonstrate how solar, battery storage, and backup generation are being combined to safeguard critical infrastructure during emergencies. When the main grid fails, these microgrids act as an "islanded" power supply, keeping essential services operational.

AGL’s Holistic Energy Strategy

AGL’s recent activity indicates a strategic pivot toward becoming an aggregator of distributed energy. The 2025 acquisition of Tesla’s South Australian VPP was a defining moment, allowing AGL to coordinate thousands of home batteries as a single, virtual resource within the National Electricity Market (NEM).

By marrying these large-scale agricultural microgrids with its residential VPP portfolio, AGL is constructing a sophisticated mosaic of distributed resources. This dual approach—managing both massive industrial sites and distributed residential networks—positions the company to stabilize the grid during peak demand while providing customers with reliable, sustainable energy.

Conclusion: Looking Ahead to 2026 and Beyond

As the energy transition continues, the success of the Koompartu Farms project serves as a compelling proof-of-concept. It demonstrates that the technical challenges of scale—whether it be managing 11 substation kiosks or spanning nearly 10,000 hectares—can be overcome with intelligent engineering and collaborative business models.

For stakeholders interested in the evolution of energy storage and grid management, the discourse will continue at the upcoming Battery Asset Management Summit Australia 2026, held in Sydney this August. As the industry moves toward 2030, projects like Koompartu will likely be remembered as the moment when the Australian agricultural sector moved from being a passive energy consumer to an active participant in the decentralized energy revolution.

By prioritizing reliability, sustainability, and technological integration, AGL and its partners are not just powering orchards—they are providing the blueprint for the next generation of industrial energy autonomy.
