Treasury Wine Estates (TWE) is now the home of Australia’s largest winery solar installation.

Unveiled at the wine producer’s Barossa Winery and Production Centre in South Australia, the solar system means iconic Australian wines including Penfolds, Wynns, Squealing Pig and Pepperjack are on track to meet the company’s target of being produced using 100% renewable electricity by the end of 2024.

Featuring almost 6,000 solar panels at the Barossa site alone, the Australian systems are expected to generate more than 5,500MWh of electricity per year, the equivalent of powering 900 homes.

The system has been designed to maximise the capacity of Barossa’s regional renewable electricity infrastructure, with the landmark investment in Australia’s wine industry another demonstration of TWE’s leadership in sustainability.

It complements other systems already online across TWE’s Australian sites, including Coldstream Hills in Victoria’s Yarra Valley, Penfolds in South Australia’s Magill, and Wynns in Coonawarra, South Australia, as well as a number of others across its global operations.

TWE chief supply and sustainability officer Kerrin Petty said the investment in transitioning to 100% renewable electricity was prompted by the urgency to decarbonise TWE’s global operations.

“Installing solar panels is the most significant contribution we can make to move closer to our ambition of net zero direct emissions. Unveiling the solar system here in the Barossa complements the other systems that are already operational, or scheduled to be completed in the coming year, at our sites in Australia, New Zealand, France, Italy, and the US.

“Our Napa Valley, California installation of 13,000 solar panels will make it the largest winery solar system in the US, generating half the electricity needs for each of our US wineries. It’s all part of TWE’s broader goal to make wine sustainably,” he said.

The installation of solar panels is a foundational investment that allows the company to better manage its electricity requirements across its global operations. Batteries and electric vehicle chargers for fleet, employees, and visitor cars are next in line: all contributing to supporting regional economies, improving energy efficiency, and reducing environmental impact.
