ESB Ardnacrusha Exhibition: 100 Years of History

A specially curated exhibition is celebrating the century one of the country’s most ambitious engineering projects in Irish history.

This month marks 100 years since the Shannon Scheme at Ardnacrusha on the River Shannon brought electricity to rural Ireland, accelerated industrial growth and transformed the economic and social landscape.

Unprecedented in scale and ambition,for a time, Ardnacrusha was the largest hydroelectric generating station in the world and remains a landmark of 20th-century engineering.

Pioneering in its use of concrete, steel, and cutting-edge turbine technology, it demonstrated the vision and determination of a nation set on shaping its own future.

Now, one hundred years later, that legacy is being celebrated in A Bolt out of the Blue, a specially curated exhibition commissioned by the National Built Heritage Service in partnership with ESB, with photographs provided by the Photographic Unit of the National Monuments Service.

The EBS describes the centenary as more than a commemoration,saying it is a reminder that the same spirit of ambition and innovation that powered the Shannon Scheme must continue to drive Ireland’s energy future.

“Ardnacrusha stands as a testament to what can be achieved when vision meets engineering excellence,” said Claire Quane, Head of Renewable Operations at ESB.

“The Shannon Scheme transformed Ireland in ways that were almost unimaginable in 1925. As we look towards a net zero energy system, we draw inspiration from that same pioneering spirit. The challenges of today demand nothing less.”

The ESB says the exhibition invites visitors to step into a defining chapter of Irelands past, while reflecting on how its legacy continues to power our future.
