Sugar cane growers in North Queensland are grappling with the dual challenges of rising electricity costs and restricted access to peak-time energy. According to irrigation specialist, Chris Doblo, of Farmacist Pty Ltd, the solution lies in smarter, more efficient practices. Drawing on his extensive experience, Mr Doblo shares practical strategies for growers to future-proof their operations and adapt to these mounting pressures.
One of the most critical steps for growers, Mr Doblo advises, is to evaluate their current irrigation systems. With potential restrictions cutting irrigation time by 20 per cent, it is essential to optimise systems to deliver more water in less time.
Automating For Success
Automation offers significant opportunities for growers to optimise their irrigation processes. With limited irrigation hours and ongoing labour shortages, automated systems can provide precise control over water application, ensuring efficiency and consistency.
“Automation has become more accessible and affordable,” Mr Doblo explains. “It’s an effective option for growers to overcome resource and time constraints.”
Features like automated scheduling and real-time monitoring allow water to be applied during off-peak energy periods, maximising cost savings.
Harnessing Solar Power
Solar energy continues to be one of the most practical investments for sugar cane growers. For pumps of 18.5 kW or larger, installing a solar array can significantly reduce reliance on grid electricity, particularly during daylight hours when energy demand is highest.
Planning For Off-Peak Energy
Aligning irrigation schedules with off-peak energy tariffs, such as Tariff 34, offers growers immediate savings of up to 30 per cent. While these tariffs may face additional restrictions in the future, Mr Doblo emphasises their current value in reducing operational costs.
However, he warns growers to prepare for potential interruptions, as off-peak energy may eventually become a “switchable load” during peak demand periods. Diversifying energy sources and improving irrigation efficiency are essential to navigating these changes.
Adapting to rising electricity prices and shifting energy regulations is no easy task, but the solutions are within reach for North Queensland’s sugar cane growers. As Mr Doblo explains, “Investments in infrastructure, automation, and solar energy are not just beneficial—they are essential for the future of our industry.”
By adopting these strategies and embracing innovation, growers can overcome energy constraints and maintain sustainability.
