For the first time, photovoltaic production alone surpassed power consumption in Bulgaria – for two hours. Interestingly, even more electricity was exported at the same time.

On Friday, June 20, the active photovoltaic capacity in Bulgaria between 10:00 and 11:00 before noon was 2,935 MW, and in the following hour it grew to 3,230 MW, state news agency BTA reported. According to data from the Electricity System Operator (ESO) and the European Network of Transmission System Operators for Electricity (ENTSO-E), it exceeded the country’s entire consumption for the first time ever, by 17 MW and 313 MW, respectively.

Even more electricity was exported at the same time, as total domestic production amounted to 6,567 MW and 6,736 MW.

Of note, not all solar power went to Bulgarian consumers, given that some traders and customers have long-term contracts with other suppliers, like the National Electricity Co. (NEK) and nuclear power plant Kozloduy, the article adds.

“This is a significant event and a great success for Bulgaria and the Bulgarian energy sector. Positioning us this way – as a leading country in the production of photovoltaic energy – not only supports the implementation and fulfillment of the commitments that Bulgaria has made for decarbonization, but it also has a positive effect on the country’s investment climate. Thanks to the solar energy that we transform into electricity, we are modernizing the entire Bulgarian energy sector,” Chairwoman of the Bulgarian Photovoltaic Association Meglena Rusenova commented.

Photovoltaics are perhaps the fastest-growing private investment sector in Bulgaria, she said.

Photovoltaics are biggest factor lowering prices at the electricity exchange

Over the past two years, over EUR 2 billion have been invested in electricity production, according to Rusenova. On top of that there are capital investments in energy storage and infrastructure, she pointed out.

Solar energy contributes to reducing prices for end users, and in practice, photovoltaics are the most significant factor for lower prices on the Independent Bulgarian Energy Exchange (IBEX), Rusenova underscored.

According to ESO, a total of 3.5 GW of photovoltaic capacity has been connected in the last three years, bringing the total to 4.7 GW.
