Serbia’s wholesale electricity market recorded a sharp increase in October, with the average day-ahead price climbing 56.2% to €234.31/MWh, raising procurement risks for industrial consumers, electricity suppliers and state-owned utility Elektroprivreda Srbije (EPS) ahead of the winter demand season.
The average price on the SEEPEX day-ahead market increased from approximately €150/MWh in September. Peak-period electricity prices rose even faster, gaining 73.8% to €229.17/MWh, according to the exchange’s monthly trading data.
The price surge occurred while trading activity remained broadly stable. SEEPEX recorded 579,308 MWh of day-ahead transactions, representing a 13.2% increase year on year, while average daily traded volume reached 18,687 MWh. The difference between price movements and trading volumes points to changing supply conditions and tighter regional electricity balances as important factors influencing the Serbian market.
Industrial Consumers Face Higher Procurement Expenses
The increase in wholesale electricity prices creates additional cost pressures for energy-intensive industries, including steel production, non-ferrous metals, cement manufacturing and other industrial activities with significant electricity requirements.
The financial impact will vary depending on companies’ procurement arrangements. Businesses operating under fixed-price supply contracts or supported by effective financial hedging may be partially protected from immediate market fluctuations. Companies purchasing substantial electricity volumes at floating prices face more direct exposure.
At October’s average wholesale price, procuring 100 GWh would cost approximately €23.4 million, compared with around €15 million at September’s average level. This represents an indicative increase of €8.4 million, excluding network charges, taxes and other contractual expenses.
For manufacturers operating with narrow margins, electricity prices remaining above €200/MWh could affect export competitiveness, production planning and working-capital requirements. The overall exposure will depend on the share of electricity obtained through spot-market purchases, long-term supply agreements and companies’ own generation capacity.
EPS Faces Greater Exposure to Wholesale Market Volatility
Higher electricity prices also increase potential procurement risks for EPS, Serbia’s dominant electricity producer and supplier.
If domestic generation falls short of consumption requirements or existing contractual obligations, the utility may need to purchase additional electricity from the wholesale market at prevailing prices. The resulting financial impact depends on import volumes, domestic generation availability, contracted purchase prices and the extent to which higher procurement costs can be reflected in customer tariffs.
Although SEEPEX’s October figures do not establish EPS’s total electricity procurement expenditure, they illustrate the more expensive market conditions facing the state-owned utility.
Prices in regional day-ahead markets also repeatedly exceeded €250–300/MWh during periods of tighter supply in October. These movements demonstrate the potential for significant price increases when renewable generation declines or additional electricity imports become necessary.
Intraday Trading and Regional Market Integration
Intraday electricity trading on SEEPEX reached 3,356 MWh in October, with an average transaction price of €179.13/MWh. The volume represented approximately 0.6% of day-ahead trading, underlining the relatively limited scale of intraday transactions compared with the exchange’s main market.
Greater intraday liquidity is becoming increasingly important as variable renewable generation expands and electricity market participants require additional opportunities to adjust their positions closer to delivery. A step towards deeper regional integration came with the October 20 launch of the common ADEX continuous intraday market, connecting Serbia, Hungary and Slovenia.
The initiative provides a framework for closer cross-border trading, although market integration alone cannot prevent price increases when electricity availability is insufficient across the wider region or cross-border transmission capacity is constrained.
Storage and Demand Flexibility Gain Importance Ahead of Winter
October’s price movements highlight the growing importance of electricity storage, demand-side flexibility and diversified procurement arrangements in managing exposure to wholesale market volatility.
Battery storage systems could help market participants manage short-duration price spikes, while industrial companies with adaptable production processes may reduce electricity expenses by shifting consumption away from more expensive delivery periods.
The availability of cross-border transmission capacity, reliability of domestic generation and output from regional hydropower and renewable energy facilities will remain important factors shaping Serbia’s electricity prices during the winter season.
For investors, the market conditions strengthen the commercial case for flexibility assets and more sophisticated electricity supply arrangements. The economics of individual projects will depend on price spreads, balancing-market revenues and access to the electricity grid.
