In 2013, the installation of a 230kw solar system and 200kW solar thermal plant at De Bortoli Wines in Bilbul, which at the time was the largest solar panel energy saving initiative for an Australian winery.
This resulted in an annual production of 320,000 kW hours of renewable energy, which is equivalent to the energy usage of 40 households.
This with other initiatives resulted in an annual decrease of 1.6 million kW hours, the equivalent of 300 households usage. In addition, a solar hot water system for warming bottles was developed which allowed De Bortoli to package sparkling wine in a single operation. Prior to this, labelling sparkling wine was an operation that was carried out one to two weeks after bottling.
