Serbia’s EPS plans to build 500 MW of wind farms with strategic partner

State-owned power utility Elektroprivreda Srbije (EPS) and the Government of Serbia plan to develop a 500 MW wind farm project with a strategic partner, according to Aleksandar Latinović, Head of Ancillary Services at EPS. He also noted that a 1,000 MW solar power project is expected to be online by 2029.

The Energy Infrastructure Development Plan and Energy Efficiency Measures for the period through 2028 envisage the construction of wind farms with a capacity of up to 500 MW.

The project could be similar to the 1,000 MW solar power project with 200 MW battery energy storage systems (BESS) that Serbia is implementing with strategic partners Hyundai Engineering and UGT Renewables (UGTR).

During the presentation of EPS’s development projects at the Korea-Serbia Strategic Energy Development Forum, held in Belgrade, Aleksandar Latinović recalled that the recently built Kostolac B3 power plant, as well as the pumped storage hydropower plant Bistrica, will provide energy to balance the system.

Tenders for two solar power plants are expected next year

Increasing the balancing reserve, in his words, is crucial for integrating new renewable energy sources into the power system. He particularly highlighted the Bistrica project, noting that it will have the same energy storage capacity as all currently existing BESSs in Europe. According to Latinović, the plant is expected to be operational by 2031 or 2032.

Latinović also recalled that EPS recently inaugurated Petka, its first solar power plant on a coal tailings dump. Though a small project, it is significant because EPS owns several thousand hectares of similar tailings and ash dumps.

The solar power plants Kolubara A (78 MW) and Morava (42 MW) are in the development phase, with tenders expected to be announced next year. Meanwhile, the Klenovnik project (110 MW) is undergoing a review of its preliminary feasibility study.

The 1 GW solar project is expected to be connected to the grid by 2029

Regarding wind energy, the 66 MW Kostolac wind farm is scheduled to begin trial operations next month.

For other wind farm projects, EPS and the Serbian government plan a 500 MW project with a strategic partner, he noted, stressing that EPS is willing to acquire already developed, construction-ready projects.

Latinović recalled that the preparation of a spatial plan for the 1 GW solar power project is underway. Strategic partners have already begun preparing investment and technical documentation, and a grid connection agreement with transmission system operator Elektromreža Srbije (EMS) has been signed.

A shortage of balancing energy could be an issue

According to the project timeline, this project will be operational and connected to the grid within four years, Latinović noted.

He stressed that integrating new renewable energy sources into the power system could lead to a shortage of balancing reserves. It is also possible, in his words, that there will be an excess of electricity when a significant amount of renewable energy is produced.

For this reason, EPS has initiated a study to analyze the use of hydrogen and heat storage.

The main focus of this study will be optimizing surplus electricity from intermittent renewable energy sources, increasing the system’s balancing reserve, replacing fuel oil in coal power plants with hydrogen-based fuel, and substituting gas and coal in heat production, Latinović explained.
