Bulgaria’s Electricity System Operator (ESO) said total volume of wind, solar and biomass power in the transmission grid jumped 45.5% from the beginning of 2024 on a year-to-year basis.

Electricity production and consumption in Bulgaria are lower year to date than in the same period of 2023. The drops registered by ESO, the country’s transmission system operator or TSO, amount to 8% to 23.73 TWh and 1.4% to 22.91 TWh, respectively, through August 18. The balance of exports and imports tumbled 68.1% to 818 GWh.

The share of conventional plants, producing baseload energy, came in at 71.6%.

Renewables in the transmission grid accounted for 9.3% and the same category in the distribution or low-voltage network landed at 9.1%. It consists of wind and solar power and biomass-fueled facilities output.

The remaining 10% were hydropower plants, the report showed.

In comparison, the combined renewables share was just 12% last year through August 18, against hydropower’s 8.9%.

Bulgaria’s electricity mix is rapidly turning greener due to the solar power boom and an accelerated coal phaseout, together with a string of outages in the Kozloduy nuclear power plant

As the activity of coal power plants is virtually collapsing and Bulgaria is experiencing a solar power boom, the electricity system is rapidly turning greener. Issues at Kozloduy, the country’s only nuclear power plant, contributed to the year-over-year shift.

The baseload item landed at 16.99 TWh or 16.7% lower than in 2023. High-voltage lines carried 2.21 TWh of renewable electricity, a jump of 45.5%. Solar power surged by a stunning 85.5% to 1.74 TWh while wind farms delivered 433 GW or 13.3% less than last year.

ESO measured 2.16 TWh of green electricity in the distribution network. The volume grew by 36.2% on an annual scale. PV plants produced 1.67 TWh, which is 60.8% more in absolute terms than in the same period of 2023. Wind parks had 403 GWh in the tally, which is 15.9% less than in 2023 until the same date.

Hydroelectric facilities contributed 2.38 TWh or 2.6% above last year’s result.
