About Hirwaun
Hirwaun is an open-cycle gas turbine (OCGT) station near Hirwaun in Rhondda Cynon Taf. Its open-cycle gas turbine starts quickly to cover peaks in demand.
Its 299 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 records it every half hour for the chart.
Gas stations follow demand: they ramp up when the wind drops or the evening peak arrives, and back off when there is plenty of wind and sun. Most are combined-cycle (CCGT); a few open-cycle turbines (OCGT) start fast to cover peaks.
