From Ardnacrusha to the Renewable Energy Revolution

When Ardnacrusha opened in 1929, it transformed Ireland’s electricity network and helped power a nation.

Nearly a century later, renewable energy generates more than 52% of Ireland’s electricity, and the grid infrastructure supporting that transition has never been more important.

Since 2021, TLI Group has helped deliver 1,037MW of renewable generation capacity, representing almost half of Irelands total installed solar capacity, by designing and delivering the substations, grid connections and supporting infrastructure that connect renewable energy projects safely and reliably to Ireland’s national grid.

As Ireland’s energy network continues to evolve, TLI Group remains committed to delivering the critical infrastructure that powers communities and supports a more sustainable future.
