The abundance of low-cost natural gas, enabling electricity producers operating gas-fired power stations to offer extremely competitive prices, is reshaping the wholesale electricity market.
Highlighting this development, the average level of the System Marginal Price, or wholesale electricity price, today, a day of strong demand, is expected to be contained below 40 euros per MWh, at 39.551 €/MWh.
Today’s electricity demand is expected to peak over 8.3 GW with total consumption reaching 168,674 MWh. The wholesale price during the peak hours will not exceed 38.850 €/MWh.
The market conditions for today are not an isolated incident but part of a wider trend that has developed during the week.
Yesterday’s average SMP was just 35.961 €/MWh despite a peak of 8,105 MW and total electricity consumption of 162,777 MWh.
On Wednesday, when demand peaked at 8,072 MW and overall consumption totaled 162,492 MWh, the SMP was 39.243 €/MWh.
The SMP exceeded the 40 €/MWh level just once this week, on Tuesday, reaching 40.689 €/MWh, a day whose peak was below 8000 MW.
The week started with Monday’s SMP average at 39.277 €/MWh, a lower peak of 7,649 MW, and total consumption for the day of 152,716 MWh.
SMP prices have been falling to even lower levels during weekends. Last Sunday, the average SMP was just 30.629 €/MWh with the peak down to 6,370 MW and the day’s consumption at 134,563 MWh.
The grid relied on just one lignite-fired power station, Agios Dimitris III, last Sunday. Demand was primarily covered by gas-fired generation, as well as renewable energy sources, hydropower units and electricity imports.
