Confronted with rising electrical energy prices that rose to about $6,000 a 12 months, a winemaker determined he had had sufficient. Joseph Evans first put in a photo voltaic power system to energy his complete property whereas the solar was shining. Nonetheless, he wished to take it a step additional. So, he began utilizing his Nissan LEAF with vehicle-to-grid (V2G) capabilities to retailer power through the day to make use of the property at evening – decreasing prices and even including an extra revenue to earnings as a result of he can promote the excess to the grid.
The winery makes use of photo voltaic power and a Nissan LEAF with V2G to scale back prices
“From a $6000 annual electrical energy invoice to $50 per week (over $2,500 a 12 months) earnings promoting my extra energy again to the grid,” mentioned Joseph Evans, proprietor of Ballycroft Vineyards and Cellars in South Australia.
After watching his electrical energy invoice rise to ,000, the winemaker took issues into his personal fingers by putting in a rooftop photo voltaic power system. The photo voltaic system powers the complete winery throughout daylight, decreasing electrical energy prices by ,000.
Evans is decided to scale back the remaining $2,000 in annual electrical energy prices that come from nightly use, which his Nissan LEAF electrical automobile saves.
Final September, Nissan introduced that it had authorized the primary V2G charger for LEAF drivers. The EV has bidirectional charging capabilities since mannequin 12 months 2013 however lacks a charging unit.
V2G permits you to ship power from the automobile’s battery again to the grid throughout peak demand to save lots of on electrical energy prices or make a revenue, as in Evans’ case.
That is greater than $2500 in annual revenue, from what was a major expense. And what’s even higher is the truth that, whereas the costs of gasoline and electrical energy solely go in a single course – and that course is excessive – my prices are mounted, and stuck at zero.
He added, “As an alternative of paying for my energy, I paid for my energy.” Ballycroft is without doubt one of the first take a look at websites in Australia to be authorized by SA Energy Networks (SAPN) to make use of V2G expertise.
It is a game-changer, and I need to be on the entrance of the queue to put in V2G. It makes me fully self-sufficient in my electrical energy wants, makes my dwelling and enterprise extra sustainable, and it is vitally straightforward to make use of.
Evans powers his enterprise and residential with a Wallbox Quasar V2G charging unit and the 40 kWh battery in his Nissan LEAF, the identical EV he drives to ship wine to native eating places. When he is achieved, he recharges the LEAF after which, at evening, plugs it right into a V2G charger to energy his dwelling and property.
In keeping with Evans, his Nissan LEAF gives sufficient power for dwelling, heating, cooling, and assembly the calls for of his 10-acre winery. He additionally has sufficient to ship again to the grid, which earns him a rebate.

V2G and bidirectional charging expertise open up new advantages for EV drivers. The power to ship power again to the grid or energy a house throughout peak hours of power demand can save utility prices and promote a sustainable power grid.
Including photo voltaic power to the V2G combine, as Bollycraft Winery did with their Nissan LEAF, helps maximize advantages and scale back stress on the grid in the long term whereas supporting self-sufficiency in electrical energy wants.
