Electricity.Trade’s May 2026 Serbia market analysis indicates that the country’s electricity system remains strongly dependent on coal, alongside rising exposure to regional power markets. In May, generation was led by coal and lignite at 56.99%, followed by hydropower at 33.49%. Renewables accounted for 8.26%, while gas contributed 0.43%. This generation structure continues to affect domestic electricity prices, industrial competitiveness, export strategies and carbon-related electricity sourcing .
Serbia turns to net imports amid weaker hydro output
The most notable market development in May was Serbia’s move into a net electricity importing position. The country imported 422.97 GWh during the month as demand increased by 4.26%. At the same time, hydro generation fell by 31.68%. Average spot prices rose to €96.63/MWh, up 5.59% month-on-month and 8.50% year-on-year .
Alongside higher import volumes, trading activity on SEEPEX increased in May. SEEPEX trading volumes grew by 16.99%. The data points to a larger role for the power exchange as Serbia becomes more exposed to regional supply and demand conditions .
Carbon intensity and traceability requirements for EU-linked industry
Serbia’s coal-based generation model continues to provide a stable source of domestic electricity, while also creating strategic challenges for market participants. Coal supports system reliability, but increasing integration with European markets brings additional emphasis on carbon intensity and electricity traceability. Sustainability requirements are also becoming more relevant for industrial consumers .
For companies exporting products to the EU, the analysis highlights a need to evidence both emissions from production processes and the origin and environmental characteristics of the electricity used. This requirement links electricity sourcing documentation to broader export compliance expectations .
Renewables documentation and verification tied to cross-border reporting
The shift also supports new commercial opportunities for renewable energy producers and industrial electricity buyers. Wind, solar and hydro suppliers can develop higher-value electricity products by providing transparent documentation on generation sources, metering data, delivery records and guarantees of origin where applicable .
For industrial consumers, verification of electricity sourcing is described as increasingly important for meeting EU customer expectations. It is also positioned as relevant for CBAM-related reporting requirements and for strengthening compliance with international supply chain standards .
Hydropower variability shapes import needs and procurement demand
May’s market data shows that renewables remained limited at 8.26%, while hydropower continued to play a major but variable role in the generation mix. Lower hydro availability can raise import dependence quickly because coal remains the dominant domestic generation source .
This operating environment increases demand for structured renewable power purchase agreements (PPAs) and transparent electricity verification systems. It also supports the need for improved matching between renewable production and consumption, alongside procurement strategies aligned with future carbon requirements .
Southeast Europe transition market profile under Electricity.Trade assessment
Electricity.Trade describes Serbia as one of the most significant electricity transition markets in Southeast Europe. The country is not yet operating as a renewable-led power system, but market liquidity is improving while its industrial sector becomes more connected to European climate and trade frameworks .
The analysis points to a widening gap between a coal-heavy domestic generation base and EU-oriented industrial export requirements as an expected theme in Serbia’s future electricity market development .
