Electricity baseload prices fell by more than 20% across several Southeast European markets for Saturday delivery, but evening prices still surged above €250/MWh, showing that weaker weekend demand has not resolved the region’s shortage of flexible generation.
Hungarian day-ahead baseload fell 26.7% to €153.09/MWh, while Romania dropped 25.5% to €155.38/MWh.
Bulgaria declined 23.5% to €153.64/MWh, Croatia 27.4% to €150.05/MWh and Slovenia 27.8% to €149.17/MWh.
Serbia fell more modestly, down 8.4% to €150.38/MWh, while Greece declined 11.3% to €161.97/MWh.
Albania remained the region’s clear premium market at around €181.58/MWh, despite falling about 8%.
The broad correction reflects lower weekend consumption, improved supply availability and stronger renewable output following extremely high prices earlier in the week.
But the baseload averages disguise the more important trading signal.
Greek prices still reached around €274.80/MWh, while 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.
The result is a widening intraday spread that increasingly matters more for asset economics than the daily average.
Solar capacity has expanded rapidly in Hungary, Romania, Bulgaria, Greece and increasingly Serbia.
During sunny periods, photovoltaic generation can push wholesale prices sharply lower.
Once solar output falls, the system must replace it with hydro, nuclear, coal, gas-fired generation, storage or imports.
Where those flexible resources are limited, prices rise rapidly.
That creates an increasingly strong revenue signal for batteries, pumped storage and flexible hydro.
Battery storage can charge during low-price periods and discharge into evening scarcity, while hydro operators can preserve reservoir generation for the most valuable hours.
The same price shape is also changing 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 the revenue available to photovoltaic plants.
Storage, structured PPAs and active portfolio management therefore become more valuable.
Saturday’s correction should consequently not be read as a return to stable power markets.
Baseload prices fell sharply because demand weakened.
The evening scarcity premium barely disappeared.
For Southeast Europe, that is the more important investment signal: the region has plenty of electricity in some hours and still not enough in the hours when it is worth the most.
