Electricity baseload prices fell by more than 20% across several Southeast European markets for Saturday delivery. Despite the decline, evening prices still rose above €250/MWh, indicating that flexibility remains priced into the most constrained hours. The day-ahead figures show weaker weekend demand alongside improved supply availability and stronger renewable output after extremely high prices earlier in the week.
Day-ahead baseload declines across regional markets
In Hungary, day-ahead baseload dropped 26.7% to €153.09/MWh. Romania declined 25.5% to €155.38/MWh. Bulgaria fell 23.5% to €153.64/MWh, while Croatia dropped 27.4% to €150.05/MWh and Slovenia eased 27.8% to €149.17/MWh.
Serbia saw a smaller decrease, down 8.4% to €150.38/MWh, while Greece declined 11.3% to €161.97/MWh. Albania remained the premium market at around €181.58/MWh, despite falling about 8%. Across the region, the broad correction coincided with lower weekend consumption and higher renewable generation.
Tighter-hour pricing keeps a flexibility premium
While daily averages moved lower, the price shape during tighter hours remained elevated in several markets. Greek prices reached around €274.80/MWh during those periods, according to the reported levels for Saturday trading hours . Hungary climbed to about €253.22 and Romania to around €246.94 during tighter hours.
At the other end of the curve, several coupled markets traded close to zero during periods of strong renewable output . This contributed to a widening intraday spread that can be more relevant for trading and asset economics than the single daily average.
Solar growth shifts dispatch needs toward flexible resources
Solar capacity has expanded rapidly in Hungary, Romania, Bulgaria, Greece and increasingly Serbia . During sunny periods, photovoltaic generation can push wholesale prices sharply lower. When solar output falls, generation from hydro, nuclear, coal and gas-fired plants, along with storage or imports, is required to replace it.
Where flexible resources are limited, prices rise quickly as scarcity returns in later hours . The same pattern supports revenue signals for batteries, pumped storage and flexible hydro: battery systems can charge during low-price periods and discharge into evening scarcity, while hydro operators can preserve reservoir generation for the most valuable hours.
Implications for renewable project revenue profiles
The changing intraday price profile also affects renewable project economics . A solar producer may generate a large share of annual output during the cheapest hours of the day, meaning annual average wholesale prices increasingly overstate revenue available to photovoltaic plants.
Storage deployment alongside structured PPAs and active portfolio management is therefore highlighted as more valuable under these conditions . For Saturday delivery, the reported baseload decline reflects weaker demand rather than a disappearance of evening scarcity pricing across Southeast Europe.
