Hydro Tasmania opens Trevallyn Dam to the public for first time

03 November 2025



We opened our doors to the public in November, giving hundreds of Tasmanians the chance to go behind the scenes at the iconic Trevallyn Dam in Launceston for the first time. 

 

More than 250 attendees took part in exclusive tours inside the dam wall and enjoyed a range of family-friendly activities, including educational games, live music, a barbecue and face painting. 

 

It was a wonderful reminder of the importance of Hydro Tasmania’s Open Days, which allow the public to get a close-up look at our assets and gain a deeper understanding of the work that goes into powering Tasmanian homes and businesses. 

 

It comes after another successful open day held at Tarraleah Power Station earlier this year. 

 

 

Executive General Manager of People and Corporate Affairs Ruth Groom said the Trevallyn event had been a fantastic opportunity to share a piece of Tasmania’s history with the community. 

 

“We were so proud to open the gates and give Tasmanians a rare glimpse inside one of our state’s most iconic dams for the first time,” said Ruth. 

 

“It was a special moment to connect with the community and share the incredible work our people do every day to keep the lights on across the State.” 

 

We have a long and proud history, employing thousands of people since building the first hydroelectric power station, Waddamana, which opened in 1916. 

 

“Our dams are part of the fabric of Tasmania – they’re not just infrastructure, they tell a story of innovation, passion and pride,” Ruth said. 

 

“It was fantastic to see so many families and locals attend the open day, learning about how our hydropower system works and celebrating what makes it unique.” 

 

 

 

Attendee Sarah Turner said the open day had been a fantastic opportunity for her children to learn about what Hydro Tasmania does. 

 

“It’s so special to be able to show the kids an asset that’s rarely open to the public,” said Sarah. 

 

“It’s not something you get to experience every day, and it’s a great way for them to see firsthand how Tasmania’s renewable energy infrastructure works and powers our state.” 

 

Our open days are part of our ongoing commitment to connect with the communities we serve, giving Tasmanians a first-hand look at the State’s renewable energy story. 

 

“Tasmania leads the nation in renewable energy, and our open days remind us just how far we’ve come,” Ms Groom said. 

 

“Our hydro system has been powering homes and communities for generations and will continue to play a vital role in a clean energy future.” 

 

“We’re proud of our history, and we’re equally excited about the future of hydropower in Tasmania.”

The legacy of John Butters >

It’s not every day that a power station evokes tears of sentimental joy but that is precisely the effect the John Butters Power Station had on one special visitor recently.

Design like a girl - tackling the gender divide in engineering >

It’s hard to believe that in 2019, some professions are still regarded as ‘male’ or ‘female’ careers. We at Hydro Tasmania believe in diversity in the workplace and are working actively to increase opportunities for women to enter and remain in traditionally male-dominated professions like engineering.
