Cold weather drives UK power prices higher

“We are seeing colder than normal weather settling into Europe over the next week which should be supportive for gas and power prices”
“Obviously we had the really warm winter in 2019, but if you look at the forecast weather models now, we are looking at temps more likely around the 25 year average. I am sure people are fed up with a Covid angle on everything, but it will be interesting to see if power and gas demand will rise more quickly in cold weather than in previous years, with those stuck working at home turning up central heating that would otherwise have been switched off if they were in the office.”


Adam Green,
Operations Manager at New Stream.



Energy prices are rising on the expectation that coronavirus restrictions may boost energy demand for heating.

If temperatures remain below normal for December then more LNG is going to be required.

Home heating demand and a more normal winter will draw down on gas storage inventories.

The UK may also have to compete with Asian LNG buying interest where prices are also up on cold.


“Most of the impact of increased heating demand is going to be seen in at the NBP (UK gas market). We have been monitoring the market closely for our green gas generators and have been flagging strength as a opportunity for short term price fixes. This seems to have worked well for them. NBP prices are almost 5% up in the space of 2 weeks. But to put this into context we are still below the average 5 year price for gas delivered over a front winter season. Demand looks robust into next week and we expect that to give a strong price signal that may attract more LNG cargoes to the UK.”

Low Wind Also Supporting Pricing

  • Low levels of generation from wind turbines are also supporting electricity prices.
  • Weather models show that there is potential for wind speeds to drop further next week.

PPA Pricing

UK gas pushing power higher.

• Domestic heating demand and colder weather increasing demand.

• The market is also supported by positive vaccine news and moves in broader commodity and equity markets.

• Lower wind speeds continue to support spot gas and power markets.

• Demand forecast remain robust in the face of renewed pan European lock-downs.

• French nuclear generation issues that could have implication across European energy markets including the UK.

• Market priced risk premium for potential shocks as we enter winter.

“More positive news for renewable generators in terms of pricing this week. The cold weather and demand side picture is the key driver.

We are keeping our PPA and GPA clients with upcoming renewals updated in order to try and time best fixing. The market continues to be volatile but there appears to be some underlying strength.”

Carbon Market Update

‘It will be interesting to see how the next few months play out, but if suppliers cannot use EU GOOs for FIT levelisation then we may see sharp upward pressure on pricing.”
