During Week 24, Bulgaria was among the more export-oriented electricity markets in Southeast Europe, with renewable generation growth and softer regional prices supporting supply conditions. The Bulgarian day-ahead electricity price fell by 7.2% to €93.58/MWh. The price level remained broadly aligned with Greece and Croatia, while staying below Romania and Hungary.
Electricity demand rose over the week, but it did not counterbalance the stronger supply-side picture. Bulgarian consumption increased by 3.0% to 477.68 GWh. At the same time, variable renewable generation expanded by 12.8%, adding support during a period of rising summer demand across the region.
Hydropower drop affects domestic balance
Hydropower was the main downside factor for Bulgaria’s domestic system balance during Week 24. Bulgarian hydro generation declined by 42.9 GWh, or 21.8%, one of the steepest falls recorded across the region. A reduction of that size would typically tighten supply conditions.
In this case, the impact was offset by higher renewable availability and flexible thermal generation. With those support elements in place, Bulgaria maintained system coverage despite weaker hydro output.
Exports rise amid improved regional conditions
Bulgaria’s net export position strengthened significantly as a result of the overall balance between demand and available generation. Net electricity exports increased by 41.3 GWh, or 103.2%. The change placed Bulgaria among the clearest beneficiaries of improved regional supply conditions during the week.
Bulgaria’s role in Balkan power flows is shaped by interconnections with Greece, Romania, Serbia, North Macedonia, and Türkiye. Those links influence regional market dynamics alongside changes in generation availability.
Cross-border flexibility and interconnector use
The market outcome reflected more than day-ahead pricing alone, pointing to cross-border flexibility and interconnector utilization as key operational factors. Even with weaker hydropower output, Bulgaria expanded exports during Week 24. This coincided with regional supply conditions supported by renewable output and thermal flexibility.
Bulgaria also functioned as a transit and balancing hub for Southeast Europe throughout the week. Shifts in renewable output, lignite generation, hydro availability, and cross-border nominations can quickly change its commercial position. Week 24 showed that stronger export performance remained possible when regional renewable and thermal conditions provided sufficient support despite hydropower stress.
