Electricity consumption also rose over the same timeframe, up 6.97% year-on-year to 18.04 TWh. Bulgaria remained a net electricity exporter, with net exports totaling 296 GWh during the first five months of the year.
Baseload generation declines while demand grows
Electricity generation from baseload power plants, including coal-fired and nuclear facilities, totaled 12.18 TWh. This figure represented a 10.4% decrease compared with the corresponding period in 2025. The change coincided with higher overall production and consumption levels reported for the first five months of 2026.
Renewables expand output across transmission and distribution networks
Renewable energy sources continued to increase their contribution to electricity generation in Bulgaria. Power production from RES connected to the transmission network rose by 14% to 1,622.9 GWh. Electricity generated from RES connected to the distribution network increased by 5.21%, reaching 1,594.7 GWh.
The latest figures show growth in both electricity production and demand in Bulgaria during the first five months of 2026, alongside continued expansion of renewable generation within the national power system.
