The plant, which is located in Azambegovo in the municipality of Sveti Nikole, in the central part of the country, comprises 31,772 solar panels covering a surface area of 300,000 square metres, the government said in a press release on Monday.
It is expected to generate 25,000 MWh of green energy annually, enough to power more than 5,500 homes.
GEN-I won the right to build the power plant in a public tender in 2019, according to information posted on the company's LinkedIn page.
Krsko-based GEN-I operates in more than 20 European countries and has 16 subsidiaries that employ more than 400 people. The company offers services in the trading, sale and purchase of energy products.
