Bulgarian Power Market Hits European Highs
Bulgaria claimed the highest day-ahead electricity prices in Europe on October 12. Sustainability expert Boyan Rashev detailed the surge in an analysis published on the MindYourFuture blog and highlighted by Sega, pointing directly to the arrival of autumn rain and heavy cloud cover that instantly crippled the country’s photovoltaic generation.
Before this spike, the industry had focused on reports of record-high prices throughout the summer, excluding 2022. During that period, market stability was often justified by the fact that the economies of Italy, Hungary, and Romania were consistently paying even higher rates, allowing a small group of highly capable Bulgarian investors
to capture significant profits from energy trading.
The Growing Spread Between Night and Morning
Rashev observed that the spread between night and morning prices now exceeds the traditional spread between day and evening.
Household consumption faces mounting pressure. Heating systems and heat pumps routinely triple residential electricity demand, while an expanding fleet of electric vehicles demands continuous daily charges.
Struggling Wind and Solar Output
Grid data from the day revealed that battery storage facilities had to lean heavily on lignite-fired thermal power plants and major imports simply to recharge.
The generation shortfall was widespread across renewables. Wind power production averaged below 80 gigawatts out of a total 780 gigawatts of installed capacity nationwide. Solar installations offered virtually no relief, peaking briefly at 1.5 gigawatts for just one to two hours from a total capacity exceeding 7 gigawatts before cloud cover blocked the sun entirely.
Thermal Plants Sit Idle Awaiting Action
According to Rashev’s assessment, lowering prices during such steep generation drops requires a massive, reliable baseline supply.
Bringing the AES Galabovo thermal power plant online at full capacity stands out as one of the few viable, immediate measures to restore stability. For now, however, its units remain idle, sitting and waiting for government action. Analysts caution that even this emergency measure will fall short once sustained winter cold takes hold.
