Earba pumped-storage hydro

Earba is Gilkes Energy’s consented pumped-storage hydro scheme near Loch Laggan in the Scottish Highlands. Water would be pumped from Loch Earba to Loch Leamhain for storage, then released through turbines to supply electricity when required.[1][2]

Current position

Foresight’s second energy infrastructure fund has invested in Gilkes Energy’s Earba pumped-storage hydro project in the Scottish Highlands. The amount was not disclosed. The investment will support detailed engineering, procurement, site investigations and preparations for construction. The consented scheme is designed to deliver 1.8GW of power and store 40GWh of electricity. Main construction has not begun.

Project details

  • The design combines 1,800MW of power with 40,000MWh of stored energy, equivalent to about 22 hours at the stated full output.
  • The scheme received planning consent in March 2025. Investment supports engineering and preparation before main construction.
