Power Equipment Australasia

OPERATOR PROFILE Ballycroft Vineyard and Cellars in South Australia’s famous Barossa Valley recently installed a V2G (Vehicle-to-Grid) electric energy system, which helps power everything from household utilities to outdoor power equipment. John Power reports. Vineyard Toasts Energy Self-Sufficiency OPERATOR: Ballycroft Vineyard and Cellars REPRESENTATIVES: Owners Joseph and Sue Evans LOCATION: Barossa Valley, South Australia CONTACT: www.ballycroft.com Joseph and Sue Evans, from Ballycroft Vineyard and Cellars, are in the process of electrifying their entire property’s mechanical infrastructure. As vineyard owners, Joseph and Sue Evans from Ballycroft Vineyard and Cellars in South Australia know that sunshine is vital for producing healthy crops. But sunshine is actually playing a much greater role in securing the profitability and security of the couple’s business – solar energy is now the cornerstone of the property’s day-to-day operations, providing affordable, self-sufficient, power to run everything from household whitegoods to agricultural assets like an electric ride-on mower and electric whipper snipper. The property has a conventional household solar array for everyday solar energy production. But what about night-time energy requirements? Most domestic solar energy systems with battery storage have fairly small capacities, typically in the range of 10-13kW. Unsurprisingly, such battery systems can become depleted in just a few hours after sunset, particularly during peak heating and cooling periods between 6-9pm. Ballycroft’s solution? Use a Wallbox Quasar V2G (Vehicle-to-Grid) system to harness the energy stored in the 40kW batteries of Joseph and Sue’s Nissan LEAF car, which can then be used to provide evening and overnight power to the property. The Nissan LEAF is the only factory-delivered and warranted, V2G-capable, all-electric vehicle on the Australian market today. Instead of paying more than $6,000pa to power their household and vineyard, Joseph and Sue now earn $2,500pa thanks to a rebate tariff which remunerates them for surplus energy at a rate of $0.08kW/h. The rebate, Joseph admits, is simply icing on the cake – the real payback is free energy, combined with full energy independence in the event of blackouts during critical winemaking procedures. (Blackouts, unfortunately, are common in the area, and can threaten an entire vintage in worstcase scenarios.) Ballycroft is one of the first properties approved by South Australian Power Network (SAPN) to use V2G technology. The Network has
