Serbia recorded the most significant electricity price decline in Southeast Europe during Week 24, with the day-ahead market average falling 21.5% to €78.22/MWh. This positioned Serbia as the region’s second-cheapest electricity market after Türkiye, where average prices remained substantially lower. While the decline provided immediate relief for power consumers, it also highlighted a broader challenge facing the Serbian electricity sector: improving price signals are not yet matched by sufficient market liquidity.
The drop in prices was supported by changing supply dynamics rather than weak demand. Serbian electricity consumption increased modestly by 2.0% to 554.08 GWh, while renewable energy production expanded strongly. Wind and solar generation rose by 76.8%, helping to increase the share of lower-cost electricity in the market. Serbia also recorded one of the lowest daily prices in Southeast Europe during the week, reaching €83.87/MWh on June 17.
Despite the growing contribution of renewables, the country’s generation mix remained heavily dependent on conventional power sources. Hydropower production declined by 4.2%, reducing the availability of flexible generation. To compensate, coal-fired plants increased output by 66.0 GWh. As a result, the lower market prices did not reflect a complete shift away from thermal generation. Instead, they demonstrated that renewable energy is becoming increasingly influential in price formation, while coal and lignite continue to play a critical role in maintaining system stability.
Beyond price movements, the more significant issue remains market depth. Serbia’s total weekly traded volume reached only 120 GWh, a fraction of the volumes recorded in larger regional markets. Italy traded 22,300 GWh during the same period, while Greece, Bulgaria, Hungary, Croatia, and Romania all recorded substantially higher exchange activity. Although falling spot prices provide useful market signals, limited liquidity restricts the ability of participants to hedge risk, support long-term contracting, and establish reliable price benchmarks.
This challenge is particularly relevant for renewable energy investment. Developers require transparent and liquid markets that can support bankable power purchase agreements and predictable revenue streams. Industrial consumers need risk-management tools that address balancing costs and long-term price exposure, while lenders and investors rely on credible market references when evaluating project financing and downside scenarios.
Week 24 demonstrated that Serbia’s electricity market is moving in the right direction, but important structural gaps remain. The strong impact of renewable generation on prices showed that the market is becoming more responsive to clean energy supply. However, limited trading activity continues to constrain commercial development. The next stage of Serbia’s power-market evolution will depend not only on adding new generation capacity but also on strengthening market liquidity, improving grid access, and expanding the contractual and financial mechanisms that can transform lower prices into sustainable investment opportunities.
