Water, sunlight and clever farm practices will strip out 10% of the energy costs for this small farm just south of Byron Bay. Otto and Lynette Saeck have been improving their business continually over the past 10 years. Their next opportunity is to optimise water application and pumping schedules and exploit the sunshine available using solar PV-generated power to reduce their grid-delivered electricity use dramatically. Other initiatives they’re considering include installing high-efficiency motors (HEMs) and variable speed drives (VSDs).
