Aurora’s GB wholesale market report provides a monthly summary of key characteristics in the wholesale market, ranging from overviews of fundamental system drivers to estimates of major company performance and snapshots of individual plant operation.
Highlights of the December report include:
- With rising carbon prices mitigating the decrease in gas and coal prices, the average power price in December increased to £61.4/MWh, a £0.2/MWh increase from the previous month.
- With lowering temperatures increasing average monthly demand by 4%, gas and nuclear enjoyed an increase in production of 1.3 TWh.
- Total monthly gross profits fell by £23.8m compared to November, due to lower utilisation rate of renewable assets coupled with looser capacity margins which resulted in the top 5th percentile of prices falling from £99/MWh to £89/MWh between months.
- Wind assets saw gross profits fall by an average of 10%, as the modest increase in wind capture price of 1% failed to ameliorate the significant drop in load factors of 6 percentage points.
