We are pleased to present our latest GB wholesale power market summary report. This report combines the highlights from our previous GB system, wind, company and plant performance notes.

Key insights from the analysis include:

  • Despite a rise in gas prices and demand, the decrease in carbon prices and increase in low marginal cost generation led to a dip in October’s average power price to £41.5/MWh, or £1.7/MWh (or 4%) lower than September
  • Lower temperatures caused monthly power demand in October to increase by 2.8 TWh (or 15%) relative to September
  • Despite a rise in demand, thermal generation fell by 1.1 TWh (or 12%) relative to September as low marginal cost generation increased by 6% (to 63% of total generation). Consequently total emissions fell by 0.4 MtCO2 (or 11%) compared to September
  • Wind assets saw an increase in their profitability in October as wind capture prices increased by £1.0/MWh (or 2%) alongside an increase in load factors of 7.5 p.p (to 42%) relative to September
