10 September 2021


Despite some Friday-on-Friday downward movements in day-ahead contracts, gas and power contracts have generally held onto the significant and unseasonably highs set across recent months. In support of this, day-ahead gas rose 4.3% to 138.75p/th, aided by periods of system undersupply and lowering wind output calling for higher gas-for-power demand. Day-ahead power fell 28.8% to £171/MWh, but remained high. Higher price points set in gas markets have supported power markets, combined with low wind outturn in the week and tighter system margins. As of 8 September, a new day-ahead baseload power record high was set, reaching £285/MWh. October 21 gas was up 6.2% at 140.93p/th, and November 21 gas increased 6.8% to 145.59p/th. All seasonal gas contracts boosted this week, up by 4.0% on average, while both winter 21 and summer 22 gas increased 7.2% and 5.4% respectively, lifting to 143.83p/th and 79.60p/th. Seasonal power contracts saw similar movements, up on average by 5.6%, as winter 21 and summer 22 expanded 8.0% and 4.4% respectively, rising to £138.00/MWh and £86.00/MWh.

Commodity price movements

Oil and Coal



  • Brent crude prices fell for the first time in three weeks, albeit marginally, down 0.4% from the week prior to $72.16/bl.
  • Despite prices retreating slightly this week, the Brent crude market continues to hold onto strong price points set in recent months, well above prices seen the same time a year ago (128% higher)
  • Bearish price movements this week were primarily driven by news earlier in the week Saudi Arabia cut contract prices with Asian markets over the prior weekend, weakening prices in the market as a result.
  • The UK ETS rose 3.4% to average £53.73/t this week, reaching a record high of £54.10/t on 6 September. The EU ETS saw similar gains, up 3.4% to average €62.42/t.
  • Gains in both schemes were underpinned by record high gas prices. European gas storage levels remain notably low, and with winter fast approaching, supply concerns for the winter season continue.
  • The return of higher auction volumes as we progress through September may see prices begin to retreat slightly in the coming weeks.
