According to data published by the Bulgarian electricity transmission system operator ESO, electricity production in Bulgaria between 1 January and 5 April 2026 declined by 1.77% year-on-year, reaching a total of 12.19 TWh. This decrease highlights a notable shift in the country’s generation dynamics compared to the same period in 2025.
At the same time, electricity consumption increased significantly, rising by 6.88% to 12.59 TWh. As a result of higher demand and lower domestic generation, Bulgaria recorded net electricity imports of 403 GWh, marking a reversal from a more balanced or export-oriented position in previous periods.
Production from baseload power plants, including coal and nuclear facilities, dropped sharply. These sources generated 8.7 TWh, representing a 14.2% decrease compared to 2025, indicating reduced reliance on traditional, stable generation capacity.
Meanwhile, the renewable energy sector showed mixed trends. Electricity generation from RES in the transmission network increased by 6.72%, reaching 871.4 GWh, suggesting stronger performance in large-scale renewable installations. However, RES output within the distribution network slightly declined by 0.43%, totaling 828.3 GWh, reflecting uneven developments across different segments of the renewable sector.
