A commercial dairy farm in Australia has slashed its use of grid electricity by up to 95%, boosting energy reliability and reducing costs with a mix of rooftop solar and Australian lithium battery technology. Fourth-generation dairy farmers John and Rochelle Pekin shifted to on-site renewables as their award-winning 950-cow Nikep Dairy Farm faced soaring power prices. Farming the Sky estimates the system will cut the farm's energy and fuel bills by $70,000 a year. The battery system is one of the first to be commercially installed by Energy Renaissance, a start-up that is building Australia’s first giga-scale battery manufacturing facility. For the Pekins, it's all about sustainability -- of the business, and of the environment. Their farm is now tracking towards becoming carbon-neutral, selling carbon credits generated by the Farming the Sky solutions, and milk to processors who reward low carbon producers with better prices.
