INVERNESS – The UK’s largest pumped hydro storage project in over four decades has achieved significant progress as SSE advances with a landmark £250m exploratory and exploratory civil engineering package at the Coire Glas site in the Great Glen. The massive energy infrastructure asset will act as a giant natural battery, pumping water uphill using surplus renewable energy and releasing it through high-capacity turbines to generate electricity during peak demand.

Specialized underground tunneling contractors are successfully advancing deep exploratory tunnels into the mountain to assess the rock geology before main dam construction begins. The project involves intricate rock stabilization, advanced shotcrete structural application, and complex subterranean drainage monitoring. This monumental engineering milestone secures the region's status as a critical hub for global green energy storage innovation, injecting millions directly into the Scottish Highlands' civil engineering and construction supply chains.
