The valuation of Southeast Europe utilities is beginning to shift as Week 23 highlighted flexibility as a key market premium. Generation volume remains relevant, but companies with hydro reservoirs, gas peakers, storage projects, interconnector access and active trading capabilities are increasingly positioned versus firms relying on inflexible generation or merchant renewable output.
Market data for the same period show demand and generation patterns that supported more flexible dispatch. SEE demand rose 8.2% week on week, while variable renewables fell 8.9%. Thermal generation increased 24.5%, hydro output rose 10.1%, and net imports climbed 9.1%.
Regional price spreads reflect a flexibility-driven week
Prices diverged across the region during Week 23, ranging from €128.09/MWh in Italy to €89.25/MWh in Greece. Much of Central SEE traded at €99–103/MWh. The pricing pattern aligned with a flexibility market where dispatch needs changed across supply sources.
Hydro-rich systems showed stronger outcomes when water availability improved. 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%.
Türkiye also remained a net exporter even after a 31.0% demand surge. Flexible hydro enabled systems to respond to price shape and residual demand conditions during the week.
Thermal and lignite output retained commercial relevance
Thermal flexibility continued to carry value despite carbon and fuel risks mentioned in the market assessment. Türkiye more than doubled thermal generation during Week 23, while Greece increased lignite output by 66.2%. These assets face political and environmental exposure, but they remained commercially relevant in tight conditions.
The market paid for availability when renewables underperformed and demand rose, supporting dispatch from thermal units alongside hydro adjustments.
Batteries and cross-border access add to flexibility value
BESS investment is described as the next flexibility layer. Utilities moving early into battery energy storage systems can capture evening spreads, support renewables, provide ancillary services and reduce imbalance exposure.
The assessment links rising solar penetration to an expected role for storage in separating higher-quality renewable portfolios from simpler megawatt-focused generation.
Interconnector optionality in Italy supports spread monetisation
Interconnector access is identified as another valuation driver for utilities with cross-border capabilities. Italy’s premium price of €128.09/MWh, together with net imports of 950.91 GWh, is cited as evidence that export optionality has value.
The market view also points to utilities with access to constrained corridors, trading desks and regional optimisation capabilities as better able to monetise spreads than purely domestic generators.
What investors focus on shifts toward dispatch capability
The shift in valuation approach changes how companies are assessed beyond installed capacity and annual generation figures. It also extends beyond regulated tariffs as a sole indicator of value for Southeast Europe utilities.
The key factors listed are portfolio flexibility, exposure to fuel costs, control of storage or hydro resources, grid position strength, and ability to trade across borders.
Energy transition dynamics increase volatility-linked flexibility needs
The energy transition is described as increasing the flexibility premium because more solar and wind raise volatility levels in power markets. Higher volatility is associated with greater value for assets that can shift output, store electricity, balance supply-demand or trade electricity across regions.
This relationship is tied back to Week 23 as a practical demonstration of the change in market conditions .
