The UK power system is expected to be “reasonably” tight today, according to npower’s daily market report.

The peak margin is estimated to be around 9GW later today.

Wind generation is currently at 2GW.

The French interconnector has started to export to the UK after a period of imports while the Dutch one continues exporting at around 1GW.

The gas system is forecast to close 41mcm long.

There is increased flows from St Fergus and Bacton gas terminals which, along with a reduction of 5mcm sent to the continent, have provided a very healthy gas system today.

Gas demand is expected to out-turn about 50mcm below seasonal normal levels despite cooler temperatures predicted until early next week.

Alex Guiot from the Optimisation Desk said: “Also the most important news that has led to volatility is the postponement of French utility EDF’s nuclear plants by a month. The country is mainly importing from its neighbouring countries including the UK.

“December prices in France are trading at €137/MWh (£120.5/MWh). In the UK, the bullish move seen in the morning eased somehow but we are likely to see markets closing higher than yesterday.”

Brent oil is currently trading at $45.65/bbl (£36.52/bbl).

Mr Guiot went on: “Early indication from the far East this morning suggests Brent oil prices are on course for their sixth straight day of falls today, dragged lower by a surge in US crude inventories, timid demand and doubts over the ability of producers to co-ordinate output cuts.

“Analysts said markets were also weighed down by traders pulling out money from futures ahead of the US presidential elections, which are seen as a risk to markets.”
