Norwegian outages take out supply
Unplanned restrictions at the Sleipner, Oseberg and Åsgard fields removed roughly 40 mcm/day of Norwegian capacity, and about 37 mcm/day was still curtailed on Tuesday morning according to Gassco data. UK North Sea output was around 82.5 mcm/day and the UK system was about 6 mcm/day short.
Cold and calm from Thursday
Forecasts show the weather turning abruptly colder from Thursday, with wind output across north-west Europe falling to a load factor of 3% to 6% from Thursday to Saturday. That points to higher gas burn for power and wider swings in prices within the day.
UK power jumped as wind dropped
UK day-ahead power settled at 11.0 p/kWh on Monday against 3.7 p/kWh on Friday after wind output fell away following a windy weekend. Three Heysham nuclear units were fully or partly offline and Belgium's Doel 4 is out until 1 November.
Where prices stand
UK gas for Sum-27 firmed 1.5% to 5.83 p/kWh at the 22 October close, the latest Market Table data we hold, and Win-27 gained 1.4% to 5.55 p/kWh. UK power for Sum-27 was little changed at 12.99 p/kWh while Win-28 rose 1.5% to 8.90 p/kWh. At the 26 October close TTF was 95.82 EUR/MWh, up 2.5% on the day.
Britain's generation mix this morning
