Kosovo`s Transmission, System and Market Operator (KOSTT) marked its 20th anniversary on Tuesday, with officials highlighting the company`s role in strengthening the country`s energy system and outlining plans for future investments.

Acting Prime Minister Albin Kurti described KOSTT as one of Kosovo's success stories, saying the operator has made significant investments over the past two decades to modernize the electricity transmission network and enhance energy security.

He also emphasized investments in renewable energy and the integration of Kosovo's electricity market with Albania through ALPEX. According to Kurti, electricity traded on the day-ahead market increased from 1,172 GWh in 2024 to 1,670 GWh in 2025, while trading reached 1,180 GWh in the first half of this year.

Acting Minister of Economy Artane Rizvanolli said one of KOSTT's biggest challenges had been the issue of unpaid electricity consumption in northern Kosovo until 2024, which she said cost citizens more than €350 million. She added that electricity consumption in the four northern municipalities has fallen by 20 percent this year.

Rizvanolli also criticized Serbia for continuing to block power transmission lines, saying the situation harms both Kosovo and the wider region.

KOSTT Board Chairman Gëzim Tosuni said the operator has become one of Kosovo's key strategic institutions, citing energy independence, resolving northern electricity losses and developing the energy market as its main achievements.

KOSTT Chief Executive Officer Trim Tërnava said the company will continue investing in the modernization of the transmission network, with a focus on integrating more renewable energy and strengthening the reliability of the electricity system.
