Building Renewable Energy into a New Dairy Operation
When planning a new dairy shed in Southland, one farming operation saw an opportunity to think differently about how the site would be powered.
With a goal of electrifying more of the new shed’s equipment and reducing reliance on purchased electricity, energy infrastructure became an important part of the development from the outset.
Ernest Energy worked alongside the client to design and deliver a substantial solar and battery solution that would support the farm’s day-to-day energy requirements while providing greater control, resilience and flexibility for the future.
Planning Energy from the Beginning
One of the advantages of a new farm development is the opportunity to consider future energy requirements before construction is complete.
Rather than adding renewable energy infrastructure later, the client was able to incorporate solar generation and battery storage into the wider planning of the new dairy operation.
For an increasingly electrified farm, this approach offered significant advantages. Generating electricity on site could help reduce the amount of power purchased from the grid, while battery storage provided greater flexibility around when that energy could be used.
It also meant the farm’s energy infrastructure could be developed with both its current requirements and future growth in mind.
A Solar and Battery Solution Designed for the Farm
Every agricultural site brings its own operational and physical considerations, and this project was no different.
Ernest Energy developed a large-scale solar and battery system around the requirements of the property, carefully considering how the renewable energy infrastructure would integrate with the new dairy operation without compromising the practical day-to-day use of the site.
The result is an integrated system that allows renewable electricity generated on farm to contribute directly to the dairy operation, with battery storage providing another layer of energy flexibility and resilience.
Importantly, the solution was designed around the way the farm operates — rather than asking the farming operation to adapt around the technology.
Performing Ahead of Expectations
Since commissioning, the system has delivered an encouraging early result, with solar generation approximately 10–15% higher than originally predicted.
That performance is helping the farm offset electricity purchased from the grid, while the addition of battery storage provides greater control over the energy generated on site and improves overall energy resilience.
For an operation designed with increasing electrification in mind, these benefits extend beyond immediate electricity savings. The system provides an energy platform capable of supporting the farm as its requirements continue to evolve.
Investing in the Future of Farming
This project demonstrates the opportunity for farmers to consider energy as part of the bigger picture when developing or upgrading farm infrastructure.
Solar panels and battery storage are no longer simply additions to an existing electrical system. When considered as part of the wider farm development, they can become an integral part of how an operation manages its electricity use, operating costs and future energy requirements.
By bringing renewable energy into the project from the beginning, this Southland dairy operation has created a more resilient and flexible approach to power — one designed for the needs of the farm today and the increasingly electrified farming environment ahead.
For Ernest Energy, it is another example of how carefully designed agricultural solar and battery solutions can be integrated into working farms at scale, delivering practical energy benefits without losing sight of how the farm needs to operate.
