About Garry hydro scheme
Garry hydro scheme is a group of hydro stations in Glen Garry in the Highlands. Its two stations, Quoich and Invergarry, were commissioned in 1955 and 1956. Its stations are traded as one unit, so their output shows here as one.
Its 40 MW of registered generating capacity is spread across one balancing mechanism unit. Every half hour each unit tells the grid how much it will generate (its physical notification): that is the live figure above, and GridMonkey has recorded it every half hour since it was added to the list in October 2026, for the chart.
Hydro stations run on rivers and reservoirs, most of them in the Scottish Highlands. How much they generate depends on the rain and on when the grid needs them.
