Gas-fired generation in the UK hit its highest in almost a decade last November; the gas-fired power plants consumed above 90mn m³/d. Due to high power transmission system demand, the day-ahead power prices increased to reach £142.15/MWh this month.
Low wind power generation was a significant factor for this spike, as it recorded less-than-average output during the month. This led to the use of open-cycle gas turbine (OCGT) units, which are less efficient and only deployed when power demand is at its highest.
Predictions of low wind output, along with forecasted temperatures reaching 0°C this month, are expected to cause high power demand.
