Gas-fired electricity generation across the Southeast European markets covered fell 13.60% in the week to 20 September, outpacing a 6.37% drop in regional power demand. Gas-fired output declined to 3,444.30 GWh from 3,986.41 GWh a week earlier. Coal and lignite generation rose 1.30% to 3,380.18 GWh. Total thermal generation fell 6.81% to 6,824.48 GWh.
Country-level changes in gas-fired dispatch
The country pattern varied across the region. Italy reduced gas-fired output by 10.86%, Greece cut it by 12.46%, and Türkiye recorded a 26.16% decline. Bulgaria’s total thermal generation was broadly stable as higher gas output partly offset lower coal and lignite production.
Drivers behind the weekly generation mix
The weekly totals indicate a change in dispatch but do not show that every gas-fired unit was replaced directly by coal. Lower demand, renewable output, hydro availability and imports all affect which plants run. Differences in plant efficiency and fuel procurement costs also influence generation patterns across markets.
Implications for near-term market calls
The immediate market effect was a lower call on gas-fired generation across the region. Whether this pattern persists will be relevant for both electricity prices and gas demand as consumption moves toward winter levels.
