On 14 June 1951, the North of Scotland Hydro-Electric Board recorded the sudden death of its Deputy Chairman, Sir Edward MacColl, a loss described at the time as “irreparable” by colleagues and staff.
It was a moment that cast a long shadow over what should have been a celebration. The very next day, 15 June 1951, the official opening of Pitlochry and Clunie power stations and dams was due to take place. Instead, the planned ceremonies were cancelled, and the focus turned to remembrance for a man whose vision had helped make the schemes possible.
Seventy-five years on, that moment serves as a powerful reminder of the people behind Scotland’s hydro-electric story.
A visionary behind a national transformation
Sir Edward MacColl was a driving force in one of the most ambitious infrastructure programmes ever undertaken in the Highlands. As Deputy Chairman and Chief Engineer of the Hydro Board, he played a central role in delivering projects that would bring electricity to some of the most remote communities in Scotland.
Developed in the wake of the Hydro-Electric Development (Scotland) Act 1943, the schemes at Pitlochry and Clunie formed part of a wider network designed not just to generate power, but to transform lives, supporting jobs, improving infrastructure, and helping secure long-term economic sustainability for the region.
Today, more than seven decades later, these stations remain in operation, generating renewable energy and standing as enduring symbols of a bold and forward-thinking vision.
Engineering ambition with human impact
MacColl’s contribution extended far beyond engineering. Born in Dumbarton in 1882, he rose to become one of Scotland’s most influential industrial figures, combining technical expertise with a deep belief in the social value of electrification.
He championed the idea that access to electricity could transform communities, bringing light, heat and opportunity to homes, crofts and businesses across the Highlands. His work helped reshape everyday life in the region and laid the foundations for modern energy networks that continue to serve Scotland today.
Tragically, MacColl did not live to see the full completion of the Tummel scheme he had worked so tirelessly to advance. His death on the eve of the Pitlochry and Clunie openings marked a poignant turning point in Scotland’s hydro-electric story.
"Sir Edward MacColl’s contribution to Scotland’s hydro-electric story cannot be overstated. His vision helped bring power and opportunity to communities across the Highlands. Seventy-five years on, sites like Pitlochry and Clunie continue to reflect that legacy, both in the energy they generate and the stories they tell."

Today, Pitlochry Dam stands not only as a working hydro-electric site, but also as a place where visitors can connect with this rich history, from the engineering feats of the mid-20th century to the stories of the people who made them possible.
MacColl’s life and achievements are explored further in Shining Light: The story of Edward ‘Electricity’ MacColl, a publication by SSE’s Heritage team. Drawing on archival material, the book brings to life the story of an engineer whose determination and vision helped shape modern Scotland, and whose legacy continues to power it today.
