In January 2026, a notable intensification of gas-power coupling was observed across Europe and Southeast Europe, particularly reflected in the trajectory of TTF prices, which approached €41/MWh. This surge in gas prices had a direct impact on electricity markets, leading to elevated power prices even amidst improvements in renewable energy generation.
Italy’s energy market exemplified this trend, where gas constituted approximately 61.91% of the generation mix. During this period, Italian electricity prices averaged €132.67/MWh, firmly tethered to gas-indexed pricing mechanisms. Every trading day in January saw Italian power prices surpass €100/MWh, highlighting the strong correlation between gas price volatility and electricity pricing.
Similar trends were evident in Hungary and Romania, where declining hydroelectric availability positioned gas as the marginal fuel source. This shift resulted in power prices exceeding €150/MWh, despite only modest increases in demand. Observations indicated that expectations regarding future gas prices significantly influenced trading behaviors, with market participants factoring in fuel risks rather than relying solely on current demand fundamentals.
Conversely, regions such as Greece and Serbia experienced a temporary decoupling from this trend due to their reliance on hydro resources. The presence of dispatchable renewables allowed for some insulation from the prevailing gas-power dynamics; however, experts caution that such decoupling is not permanent and can quickly revert once hydroelectric output stabilizes.
The developments in January underscored a critical aspect of the energy landscape: gas continues to be the principal marginal driver of electricity pricing across much of Southeast Europe. The interconnectedness of these markets means that fluctuations within one sector can swiftly influence another, reinforcing the need for stakeholders to remain vigilant regarding cross-commodity interactions.
