Agile Advantage Ed. 16 - Cutting Diesel Dependency: Solar battery PPAs for remote farming operations

Remote farming operations in Australia face high operational costs, supply chain vulnerabilities, and significant carbon emissions due to reliance on diesel generators. Agile Energy provides solar-battery Power Purchase Agreements (PPAs) as a transformative solution, enabling farms to transition to reliable renewable energy without upfront capital investment.

By leveraging PPAs, farms gain predictable energy costs, operational resilience, and measurable sustainability outcomes. This approach helps farmers reduce diesel dependency while maintaining productivity and profitability, alining with broader environmental goals.

The Problem: Diesel Dependency in Remote Farms

Diesel generators are the backbone of off-grid farm operations, but they come with significant drawbacks:

• High Costs: Diesel fuel, transportation, and generator maintenance contribute to operational expenses, averaging AUD 0.50-1.00 per kWh depending on location

• Environmental Impact: Diesel generators emit ~2.7kg CO2 per litre of fuel burned, contributing to Australia's agricultural sector emissions, which account for 14% of national greenhouse gas output

• Supply Risks: Extreme weather events, remote locations, and logistical disruptions can delay fuel deliveries, threatening critical farm operations such as irrigation, refrigeration, and livestock management

These factors highlight the urgent need for a sustainable, reliable alternative to diesel-based energy

Agile Energy's Solution: Solar- Battery PPAs

Agile Energy designs, installs, owns, and operates solar photovoltaic (PV) systems paired with battery storage. Under a PPA, farms purchase electricity at a fixed or predictable rate, typically 20-40% lower than diesel-based costs

This model removes the financial barrier of high upfront capital while delivering multiple operational and environmental benefits:

Key Advantages:

• No Upfront Costs: Agile Energy covers installation, maintenance, and ongoing operations

• Cost Predictability: Fixed PPA rates (AUD 0.15-0.25/kWh) shield farms from diesel prices volatility, which ranged from AUD 1.50-2.20 per litre in 2024-2025

• Energy Resilience: Battery storage ensures continuous power supply, even during low solar output or fuel shortages

• Sustainability: Solar battery-systems reduce emissions by up to 80% compared to diesel generators, supporting Australia's net-zero emissions target by 2050

By integrating solar and storage, Agile Energy enables farms to operate more efficiently, reliably, and sustainably, while providing long-term financial certainty

Australian Case Studies

Case Study 1: Northern NSW Cattle Farm

System: 200kW solar PV + 500 kWh battery storage

Outcomes:

• Diesel consumption reduced by 60%

• Annual savings of AUD 45,000 on fuel and maintenance

• Stable energy costs during peak summer demand

• CO2 emissions reduced 135 tonnes per year

This installation demonstrates how hybrid solar-battery systems can significantly reduce operating costs and emissions for off-grid farms

Case Study 2: Queensland Irrigation Cooperative

System: 500 kW solar PV + 1 MWh battery storage across 15 farms

Outcomes:

• Eliminated AUD 120,000 in annual diesel costs

• Stabilised energy costs for water pumping and processing

• Reduced emissions by 320 tonnes CO2 annually, supporting cooperative sustainability goals

These examples highlight the scalability of Agile Energy's solutions, from individual farms to multi-farm cooperatives.

Implementation Framework

Agile Energy follows a structured approach to ensure each PPA delivers optimal performance:

System Design:

• Comprehensive energy audits assess farm-specific needs such as irrigation, refrigeration, and livestock operations

• Solar resource assessments optimise system sizing, leveraging Australia's high solar irradiance (average 5-6 kWh/m2/day)

PPA Structure:

• Contracts typically span 10-20 years, with fixed or inflation-indexed energy rates

• Agile Energy manages installation, maintenance, and performance guarantees, removing operational risk for farmers

Regulatory Compliance:

• Systems comply with Australian Standards (AS/NZS 3000) and Clean Energy Council guidelines

• Eligible for federal Small-scale Technology Certificates (STCs) and state-level incentives, further improving financial outcomes

Monitoring & Maintenance:

• Real-time monitoring via cloud-based platforms ensures continuous system performance

• Predictive maintenance minimises downtime, achieving up to 99% system uptime

Market Context

Remote Australian farms consume 500-5,000 kWh daily, depending on operation size. Diesel costs in remote areas have risen 15% since 2023, driven by supply constraints and transport logistics.

Agile Energy's solutions position farmers to capitalise on these trends, reducing energy costs and emissions while enhancing operational resilience.

Conclusion

Agile Energy's solar-battery PPAs provide a financially viable, sustainable solution for remote farms seeking to reduce diesel reliance.

Key benefits include:

• Cost savings: 20-40% lower than diesel based energy

• Operational reliability: Continuous, resilient power for critical farming operations

• Environmental outcomes: Up to 80% reduction in CO2 emissions

With no upfront costs, scalable systems, and predictable energy pricing, Agile Energy empowers farmers to achieve energy resilience and align with Australia's low-carbon future.
