Serbian wholesale electricity prices remained above €150/MWh on average during August, while evening prices climbed beyond €400/MWh and occasionally €500/MWh, exposing growing volatility in the country’s increasingly interconnected power market.
Regional supply constraints have combined with high summer demand and poor hydrology to keep prices elevated.
Hungarian baseload prices have been running at roughly €175/MWh, while reduced nuclear availability across Hungary and Romania has tightened firm generation throughout Southeast Europe.
Serbia has also been affected by exceptionally weak hydrology at the Djerdap hydropower complex, where Danube inflows have fallen to around 1,400 cubic metres per second.
At the same time, the rapid growth of solar generation across Southeast Europe is transforming intraday price formation.
Electricity that historically tended to be expensive during daytime industrial hours can now become relatively cheap around midday as photovoltaic generation peaks. Prices then rise sharply after sunset as solar production disappears while household and commercial demand remains high.
That increasingly pronounced evening ramp is creating opportunities for batteries, pumped-storage plants, flexible gas generation and traders capable of shifting electricity across hours rather than simply between countries.
The pattern is also increasing Serbia’s exposure to events elsewhere in Europe. Outages or hydrological constraints in Hungary, Romania or Bulgaria can quickly influence Serbian prices through interconnected markets.
Winter therefore presents a different but related risk. Stronger heating demand combined with weaker solar output could increase reliance on thermal generation and imports, particularly if hydro reservoirs enter the colder months at low levels.
