According to data published by the Bulgarian electricity transmission system operator ESO, electricity production in Bulgaria in the period from 1 January to 19 April 2026 declined slightly by 0.86% compared to 2025, reaching a total of 13.89 TWh.
At the same time, electricity consumption increased significantly, rising by 5.72% year-on-year to 14.02 TWh, which pushed the system into a net import position. As a result, Bulgaria recorded net electricity imports of 137 GWh in 2026.
Production from baseload power plants, including coal and nuclear facilities, fell more sharply over the period. Total output from these sources dropped by 13.5% compared to 2025, reaching 9.77 TWh, reflecting reduced reliance on conventional generation in the national mix.
In contrast, electricity generation from renewable energy sources (RES) continued to grow. RES production connected to the transmission network increased by 8.3%, reaching 1,037.9 GWh, indicating stronger output from large-scale renewable installations.
Similarly, RES generation in the distribution network also expanded, rising by 1.7% year-on-year to 1,004.6 GWh, highlighting steady but more moderate growth in decentralized renewable production across the country.
