Serbia has emerged as the key short-term stress market in southeast European power after day-ahead prices rose sharply in Week 27, supported by higher import dependency and weaker domestic thermal generation.
Serbian day-ahead power averaged EUR 139.93/MWh during the week of 29 June–5 July, up 26.3% week on week, making it one of the strongest price movers in the region. The increase placed Serbia behind Romania, Hungary and Croatia in outright price terms, but ahead of Greece and Bulgaria.
The market’s stress signal was reinforced by cross-border flows. Serbia moved from a marginal net import position of 7 GWh in Week 26 to 90 GWh in Week 27. This shift suggests the market became more exposed to regional supply conditions and import-price competition.
The supply-side picture also tightened. The report noted that Serbian thermal generation fell steeply during the week, following the absence of lignite generation. In a market where lignite can be an important baseload source, reduced availability can quickly increase reliance on imports and higher-cost marginal supply.
Serbia’s position matters because it sits inside the wider Romania-Hungary-Croatia premium corridor. Romania averaged EUR 164.31/MWh, Hungary EUR 162.04/MWh and Croatia EUR 142.57/MWh, meaning Serbian import needs were rising into an already expensive regional market.
For traders, the immediate focus should be on whether Serbia’s thermal availability normalises. If lignite output returns, Serbian import needs could ease and the country’s price premium may narrow. If availability remains constrained, Serbia could continue to act as a regional price-support market.
Weather and renewable output will also be important. A wind or hydro recovery in neighbouring markets could improve available supply, while continued low renewable output would leave Serbia more exposed to imported thermal power and regional evening peak prices.
Market view: Serbia should be treated as the main SEE stress watch market. The key indicators are lignite availability, net imports, regional spreads and evening peak prices.
