Bulgarian electricity generation rose 11.33% year on year to 32.61 TWh between Jan. 1 and Sept. 20, supported by strong growth in renewable production.
Domestic electricity consumption increased by 8.19% to 29.48 TWh, leaving Bulgaria with net exports of approximately 3.13 TWh over the period.
Production from baseload plants, including coal and nuclear facilities, declined 3.6% to 20.13 TWh. The overall increase was instead driven by renewable generation and other sources outside the traditional baseload fleet.
Renewable output connected to the transmission network jumped 25.57% to 3.86 TWh, while renewable production in distribution networks increased 9.53% to 3.41 TWh.
The figures reinforce Bulgaria’s position as a net electricity exporter in southeastern Europe, but they also show a structural change in the sources supporting that surplus. Renewable generation is expanding while output from coal and nuclear plants declines.
That transition gives Bulgaria more electricity for regional trade but increases the need for storage, flexible generation and grid investment. Export availability will increasingly depend on weather and hourly renewable production rather than the stable baseload profile that historically underpinned the country’s regional market role.
