Krivača wind farm – the first wind power plant south of the Sava and Danube rivers

Krivača wind farm (103 MW) is the first wind farm in Serbia built south of the Sava and Danube rivers. It is located in the Braničevo district, only six kilometres from the Đerdap Gorge and the Romanian border. This project represents a significant step in Serbia’s transition toward renewable energy sources and in increasing the country’s green-energy capacity.

Construction took place from March to July 2023, with the key period of intensive works occurring at the June peak, when more than 90 workers and engineers operated simultaneously across seven different sites.

• Total installed capacity: 103 MW
• Number of turbines: 22
• Turbine type: Nordex 4.8 MW
• Planned annual production: 310 GWh
• Area: 242 ha
• Grid connection voltage: 110 k

• Coordinating works across seven separate locations with multiple operational teams
• Working under variable weather conditions, including strong winds and high summer temperatures
• Construction of a complex internal road system, totalling 13 km of internal roads
• Installation and connection of electrical equipment to enable safe grid integration
• Logistical synchronization of materials and workforce to ensure optimal delivery and assembly of equipment

Elnos Group acted as the main contractor for Balance of Plant (BoP) and Connection Works (CW), which included:

• Construction of 13 km of internal roads within the wind farm
• Construction of a 33/110 kV substation
• Construction of the 110 kV connection switchyard (PRP Krivača)
• Expansion of two existing 110/35 kV substations – Veliko Gradište and Neresnica
• Construction of two 110 kV transmission lines
• Laying of 10 kV cables for auxiliary power supply (PRP)

• Increasing Serbia’s renewable-energy capacity, with potential to supply more than 62,000 households
• Reducing CO₂ emissions by more than 280,000 tones annually
• Supporting Serbia’s energy transition and reducing dependence on fossil fuels
• Strengthening power-system stability in the Braničevo region and the Đerdap Gorge area

Krivača wind farm is a strong example of successful integration of renewable energy into Serbia’s electrical grid. Elnos Group once again proved itself a reliable partner in delivering complex infrastructure and energy projects.
