Electricity.Trade analysis confirms that gas-power coupling intensified across Europe and South-East Europe during January 2026. As TTF prices rallied toward €41/MWh, gas-heavy power markets responded with elevated electricity prices, even where renewable output improved.
Italy provided the clearest example. With gas accounting for 61.91% of its generation mix, Italian power prices averaged €132.67/MWh, remaining firmly anchored to gas-indexed marginal pricing. Electricity.Trade notes that Italian prices exceeded €100/MWh on every trading day in January, reflecting the direct transmission of gas volatility into power markets.
Hungary and Romania exhibited similar dynamics. Declining hydro availability exposed gas as the marginal fuel, pushing power prices above €150/MWh despite modest demand growth. Electricity.Trade observed that forward gas expectations influenced power bidding behavior, with traders pricing fuel risk rather than immediate fundamentals.
In contrast, hydro-rich Greece and Serbia temporarily decoupled, illustrating that dispatchable renewables can interrupt gas-power transmission. However, Electricity.Trade cautions that such insulation is conditional and reverses quickly when hydro output normalizes.
Electricity.Trade concludes that January reinforced a core cross-commodity reality: gas remains the dominant marginal driver of electricity pricing across much of the region, and volatility in one market rapidly propagates into the other.
