About Errochty
Errochty is a hydro power station at Tummel Bridge in Perth and Kinross. It was commissioned in 1955.
Its 76 MW of registered generating capacity is spread across 3 balancing mechanism units. Every half hour each unit tells the grid how much it will generate (its physical notification): that is the live figure above, and GridMonkey records it every half hour 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.
