Serbia was among the Southeast Europe markets where electricity prices eased in Week 23, even as regional demand increased. The Serbian weekly day-ahead average fell 5.8% week on week to €99.63/MWh. Over the same period, SEE electricity demand rose 8.2%, while regional thermal generation increased sharply.
The price divergence aligned with changes in local supply and demand. Serbia’s electricity demand declined 1.0%, contrasting with the broader regional trend. Serbian hydro generation rose 30.8%, and thermal output also increased during the week.
Serbian fundamentals vs tighter regional conditions
Across SEE, the market tightened as demand increased and variable renewables fell. Variable renewables dropped 8.9%, while wind output declined 15.5%. Net imports rose 9.1%, contributing to firmer regional conditions.
Serbia’s balance differed from that of several neighbouring markets. Lower demand alongside higher hydro generation and improved thermal availability helped limit marginal price pressure domestically. The source data links the Serbian outcome to avoiding upward pressure seen in Bulgaria, Italy, and Greece.
Hydro’s role in day-ahead pricing
Hydro output was a key factor for Serbia’s day-ahead pricing dynamics. Water availability can materially affect prices because hydro units support flexible dispatch. Higher hydro generation can reduce reliance on higher-cost imports or thermal ramping during periods of stress.
When hydro output increases during weeks of regional tension, local prices can soften even if neighbouring markets remain firm. This relationship is presented as a mechanism through which Serbia’s domestic system responds differently than the wider region.
Lignite-based thermal generation and supply risks
Thermal generation remains central to stability in Serbia’s power market structure. The country relies heavily on lignite-based generation, which provides dispatchable output but is associated with long-term carbon and environmental constraints. In Week 23, stronger thermal availability supported the observed price decline.
The same supply balance can change quickly in subsequent weeks, depending on operational factors. The source highlights that outages, maintenance, or coal-supply issues could reverse the effect if they occur.
Implications for SEEPEX pricing and cross-border trading
The Serbian weekly average near €100/MWh places it around the regional middle on the basis of the provided comparisons. It was cheaper than Italy, Hungary, Romania, and Bulgaria, but still far above
