Navigating through the idyllic landscapes of Perthshire, the verdant expanses and tranquil waters, interspersed with rugged hills, seemed to draw me towards a significant milestone in Scotland’s renewable energy landscape. The Tummel Bridge Power Station, a cornerstone of the Tummel Valley Hydro Scheme, has been officially reopened following a substantial £50 million refurbishment. I had the pleasure of discussing this monumental project with Fiona MacLeod, Senior Project Manager at SSE Renewables, who provided invaluable insights into the intricacies and achievements of this venture.

Fiona welcomed me with a warm smile and a palpable air of enthusiasm. As we delved into our conversation, her passion for the project was infectious. “The reopening of Tummel Bridge Power Station is not just a professional milestone for me but a personal one as well,” she began. “Being part of a project that preserves a piece of our industrial heritage while propelling us towards a greener future is incredibly fulfilling.”
Originally commissioned in 1933, the power station had been a reliable source of renewable energy for nearly ninety years. However, the need for modernisation was clear. “The original ‘Camel Back’ twin-runner horizontal Francis hydro turbines were revolutionary for their time, but technology has significantly advanced since then,” Fiona explained. “The new modern runner technology we installed increases water flow and generation output, ensuring the station’s efficiency and extending its operational life by at least another forty years.”
The refurbishment was a formidable undertaking, involving meticulous planning and coordination with various stakeholders. “At the peak of construction, we supported around 65 roles, many of which were local Highland contractors,” Fiona noted. “This project has been a significant boost for the regional supply chain and local job creation, an aspect we are particularly proud of.”
One of the most striking facets of the refurbishment is the technological advancements implemented. The new turbines have augmented the station’s potential generation output from 34 to 40 megawatts (MW) during optimum conditions. “This means we can generate more clean electricity with the same volume of water,” Fiona said proudly. “It’s all about maximising efficiency and harnessing the full potential of our natural resources.”
The official reopening ceremony was graced by Scotland’s Deputy First Minister, John Swinney MSP, who powered up the new units. “Having the Deputy First Minister here was a testament to the significance of this project,” Fiona reflected. “His words underscored the importance of sustainable energy and the role of projects like ours in achieving net-zero emissions.” Fiona also emphasised the community’s role in the project. “The people of Perthshire have been incredibly supportive. This station is a part of their history, and now it will continue to be a part of their future.”
No project of this magnitude is without its challenges. “One of the most complex parts was the civil works,” Fiona admitted. “We had to remove around 4,000 tonnes of concrete and 1,000 tonnes of steel. Remarkably, almost all of it was recycled or reused, aligning with our sustainability strategy.” The coordination between multiple contractors and stakeholders was another significant hurdle. “We had over 700 different people working on-site, from approximately 30 different contractors across Scotland, the UK, and Europe,” she recounted. “Ensuring everyone was on the same page required precise communication and collaboration.”
As our conversation drew to a close, Fiona expressed her optimism for the future. “This refurbishment is not just about extending the life of Tummel Bridge Power Station; it’s about setting a precedent for future projects. By investing in our existing infrastructure and modernising it, we’re making significant strides towards a sustainable future.” She added, “I hope this project inspires other regions and companies to take similar steps. The path to a net-zero future is a collective effort, and every project like this brings us one step closer.”
Driving back, the dedication and hard work that went into the Tummel Bridge Power Station refurbishment left a lasting impression. This project beautifully marries history with innovation, demonstrating that with the right investment and commitment, we can build a sustainable future while honouring our past. The Tummel Bridge Power Station stands as a beacon of what can be achieved through modernisation and community collaboration, paving the way for a greener, more sustainable world.
