Stronger European natural gas prices have added upward pressure to Southeast European electricity markets following Week 27 data showing higher thermal generation across the region. The same period also saw firmer TTF gas futures, aligning with the shift in power generation mix. The changes point to continued sensitivity of wholesale prices to fuel costs during periods of system stress.
Week 27 TTF futures rise above EUR 45/MWh
Average TTF natural gas futures reached EUR 43.59/MWh during Week 27, up 5.5% from the previous week. Prices moved above EUR 45/MWh by the end of the reporting period. The front-month TTF contract was trading near EUR 49.045/MWh, indicating market pricing that reflects tighter supply conditions.
Thermal generation increases as renewables and hydro soften
The higher gas price environment coincided with greater reliance on thermal electricity generation across Southeast Europe. Regional thermal output increased by 6.5%, rising from 6.44 TWh to 6.86 TWh. Stronger lignite, coal and gas-fired generation helped offset weaker renewable output and lower hydro production.
Within the thermal fleet, gas-fired generation rose 3.3% week on week. Lignite and coal generation climbed 11.6%. The increased share of dispatchable generation affects how electricity prices form, particularly when demand is elevated and renewable supply is reduced.
Evening peak hours remain most exposed to fuel-cost pass-through
The largest pricing risk is concentrated during evening peak hours, when solar output declines. Electricity systems then rely more heavily on thermal generation and cross-border imports. In these conditions, higher gas prices can translate into higher wholesale electricity prices, especially in import-dependent markets including Romania, Hungary, Serbia, and Croatia.
Storage levels and LNG supply uncertainties support tighter pricing
Gas market fundamentals continued to support elevated pricing during the reporting period. Higher temperatures boosted seasonal demand, while European gas storage remained around 48% full. Market sentiment was also influenced by competition for LNG cargoes and supply uncertainties related to the Strait of Hormuz, alongside the normalisation of production in Qatar.
TFF and THE benchmarks tracked alongside renewables and hydro conditions
For power traders, TTF and THE gas benchmarks are expected to remain central inputs for daily market analysis. A stronger gas forward curve supports expectations for continued tightness in Southeast European electricity markets. Conversely, a decline in gas prices would reduce part of the upside risk, particularly if accompanied by stronger wind generation or improved regional hydro output.
The broader market outlook remains linked to how European gas prices affect electricity pricing across Southeast Europe. Monitoring developments in the TTF and THE markets alongside renewable generation, hydro conditions, and evening peak demand is highlighted as relevant for assessing whether higher fuel costs continue feeding into regional wholesale power prices.
