About Connah's Quay
Connah's Quay is a combined-cycle gas turbine (CCGT) station on the River Dee in Flintshire. It was commissioned in 1996.
Its 1,409 MW of registered generating capacity is spread across 4 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.
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.
