For the first time in its energy history, Bulgaria saw solar power generation briefly exceed the country’s electricity consumption. This landmark event occurred on Friday, June 20, between 10:00 and 12:00 AM, when solar panels produced more electricity than the nation consumed during those two hours—also contributing to exports.
According to the Bulgarian electricity transmission system operator ESO, solar output reached 2,935 MW from 10:00 to 11:00 AM, and increased to 3,230 MW in the following hour. During those periods, solar energy production exceeded national electricity consumption by 17 MW and 313 MW, respectively. Overall electricity generation rose to 6,567 MW and 6,736 MW across the two hours, with the excess power largely exported.
Despite the surplus, not all solar-generated electricity was used domestically. Due to long-term contracts, some consumers continued to receive electricity from other sources, including the National Electricity Company (NEK) and the Kozloduy nuclear power plant.
This event marks a major milestone in Bulgaria’s transition toward clean energy. The Bulgarian Photovoltaic Association emphasized that the achievement reflects the country’s growing leadership in solar energy and its firm commitment to decarbonization and sustainability. It also positions Bulgaria as an increasingly attractive destination for energy investments and technological innovation.
Meglena Rusenova, Chair of the Association, noted that solar energy is currently one of the fastest-growing sectors for private investment in the country. The successful integration of solar power into the national grid points to a broader transformation of Bulgaria’s energy landscape, toward a more modern and sustainable system.
