National Grid increase reserve margin forecast
The system operator has said that it expects the UK to have a capacity margin of 6.6% this winter––up from its earlier projection of 5.5%. National Grid’s Winter Outlook report, issued on Friday 14 October, said the improvement was based on the availability of Eggborough coal-fired plant and a reduction in the power to be exported to Ireland, owing to an outage on the East West interconnector. Normalised transmission system demand is expected to peak at 52GW. Meanwhile, gas demand for this winter is expected to be lower than it was last year––mainly driven by lower exports to Ireland and continental Europe. Demand for gas in electricity generation is projected to increase, however.
