## Project summary

Earba Storage is described as a proposed pumped-storage hydro project at Loch Earba near Newtonmore. The proposal specifies 1,800 MW of installed capacity and up to 40,000 MWh of storage, using Loch Leamhain and Loch Earba as reservoirs connected by an approximately 3 km tunnel. It also includes a powerhouse extending underground, with turbines for generation and pumping. The page gives an expected construction duration of approximately six years. It reports that the scheme is the largest PSH scheme ever consented in the UK by installed capacity and stored energy, while giving no consent date or further approval details.

## Scope
Proposed scheme with 1,800 MW installed capacity and up to 40,000 MWh of energy storage. Proposed works include adapting the lochs as upper and lower reservoirs, connecting them with an approximately 3 km tunnel, and constructing a powerhouse on Loch Earba’s shore that extends underground, with turbines at the bottom of its shaft for generation and pumping.
