The valuation of SEE utilities is beginning to shift. Generation volume still matters, but Week 23 showed that flexibility may become the more important market premium. Utilities with hydro reservoirs, gas peakers, storage projects, interconnector access and active trading capabilities are increasingly better positioned than companies relying only on inflexible generation or merchant renewable volume.
The market data explain why. SEE demand rose 8.2% week on week, variable renewables fell 8.9%, thermal generation increased 24.5%, hydro rose 10.1%, and net imports climbed 9.1%. Prices diverged sharply across the region, from €128.09/MWh in Italy to €89.25/MWh in Greece and €99–103/MWh across much of Central SEE. This was a flexibility market.
Hydro-rich systems had a clear advantage where water availability improved. Serbia increased hydro output 30.8% and saw prices fall 5.8%. Croatia lifted hydro generation 73.6%. Türkiye increased hydro output 15.4% and still managed to remain a net exporter despite a 31.0% demand surge. Flexible hydro allowed systems to respond to price shape and residual demand.
Thermal flexibility also retained value, despite carbon and fuel risks. Türkiye more than doubled thermal generation, while Greece increased lignite output 66.2%. These assets are politically and environmentally exposed, but during tight weeks they remain commercially relevant. The market pays for availability when renewables underperform and demand rises.
Battery storage is the next flexibility layer. Utilities that move early into BESS can capture evening spreads, support renewables, provide ancillary services and reduce imbalance exposure. As solar penetration rises, storage will increasingly separate higher-quality renewable portfolios from simple megawatt pipelines.
Interconnector access is another valuation driver. Italy’s premium price of €128.09/MWh and its net imports of 950.91 GWh show that export optionality has value. Utilities with access to constrained corridors, trading desks and regional optimisation capabilities can monetise spreads more effectively than purely domestic generators.
This changes how investors should read SEE utilities. A company’s value should not be assessed only by installed capacity, annual generation or regulated tariffs. The key questions are: how flexible is its portfolio, how exposed is it to fuel costs, how much storage or hydro does it control, how strong is its grid position, and can it trade across borders?
The energy transition increases this flexibility premium. More solar and wind mean more volatility. More volatility means more value for assets that can shift, store, balance or trade electricity. Week 23 was a practical demonstration of that shift.
SEE utilities with flexible assets should attract a different valuation logic. The market is moving from megawatt volume to dispatch value.
