Between 1 January and 4 October, Bulgaria generated 34.46 TWh of electricity, up 12.24% year on year. The increase coincided with expanding renewable output and lower coal and nuclear generation.
Electricity consumption rose 8.45% to 30.96 TWh. Despite higher domestic demand, Bulgaria recorded net exports of approximately 3.5 TWh.
Coal and nuclear decline while other generation rises
Combined coal and nuclear production fell 3.1% to 21.25 TWh. With that decline, the growth in overall generation came from other sources.
Renewables grow on transmission and distribution networks
Renewable generation connected to the transmission network increased 27.89% to 4.12 TWh. Renewable output on distribution networks rose 10.97% to 3.62 TWh.
The data indicate Bulgaria maintained an export surplus even as consumption increased. Renewables played a larger role in meeting demand over the period.
Timing of surplus affects market value
The annual balance does not show when the export surplus was available during the year. Solar-led growth can raise daytime supply while leaving evening demand more dependent on dispatchable generation, imports or storage.
