Week 23 highlighted a shift in how Southeast Europe power utilities are valued, with flexibility emerging as a market premium alongside generation volume. Companies with hydro reservoirs, gas peakers, storage projects, interconnector access and active trading capabilities are positioned differently from firms relying mainly on inflexible generation or merchant renewable output. The change is reflected in regional dispatch patterns and price outcomes during the week.
Week 23 demand, generation mix and regional price divergence
Southeast Europe demand rose 8.2% week on week, while variable renewables fell 8.9%. Thermal generation increased 24.5%, and hydro output rose 10.1%, with net imports climbing 9.1%. Prices diverged across the region, ranging from €128.09/MWh in Italy to €89.25/MWh in Greece, with much of Central SEE trading at €99–103/MWh. The pricing pattern aligned with a flexibility-driven market environment.
Hydro output gains and price responses in Serbia, Croatia and Türkiye
Hydro-rich systems showed an advantage where water availability improved during Week 23. Serbia increased hydro output by 30.8%, and prices fell by 5.8%. Croatia lifted hydro generation by 73.6%, while Türkiye raised hydro output by 15.4%. Despite a 31.0% demand surge, Türkiye remained a net exporter.
The ability to adjust hydro dispatch supported system responses to price shape and residual demand conditions during the week. Flexible hydro helped balance changes in demand and renewable availability across the region’s interconnected markets. These outcomes were reflected in the observed price movements tied to hydro performance.
Thermal dispatch increases amid carbon and fuel exposure
Thermal flexibility also retained value during Week 23 despite carbon and fuel risks. Türkiye more than doubled thermal generation, while Greece increased lignite output by 66.2%. The week’s tight conditions supported commercial relevance for these assets when renewables underperformed and demand increased.
The market response indicated that availability from thermal units remained important when variable generation fell short of demand requirements. Dispatch changes in thermal segments contributed to meeting higher load levels across the region during the same period.
Batteries and interconnector access as additional flexibility layers
Battery energy storage systems (BESS) were identified as the next layer of flexibility for utilities seeking to capture market opportunities tied to shifting supply and demand. Moving early into BESS can enable participation in evening spreads, support renewables, provide ancillary services, and reduce imbalance exposure. As solar penetration rises, storage is expected to differentiate higher-quality renewable portfolios from simpler megawatt-focused generation.
Interconnector access was also cited as a valuation driver for utilities operating in the region’s cross-border market structure. Italy’s premium price of €128.09/MWh, alongside net imports of 950.91 GWh, was used to show that export optionality can carry value. Utilities with access to constrained corridors, trading desks and regional optimisation capabilities can monetise spreads more effectively than purely domestic generators.
How investors may assess utility portfolios under higher volatility
The shift affects how investors read Southeast Europe utility valuations beyond installed capacity or annual generation figures. The focus extends to portfolio flexibility, exposure to fuel costs, control over storage or hydro resources, grid position strength, and cross-border trading capability. These factors align with the dispatch patterns seen during Week 23.
The energy transition was linked to a higher flexibility premium through increased volatility as solar and wind volumes rise. More volatility increases the value of assets that can shift output, store energy, balance supply-demand conditions or trade electricity across markets. Week 23 was presented as an example of how these dynamics played out in practice.
