RUDIS built its first wind power plant with rated power 9 MW in Serbia

We are accelerating the development of carbon neutral programs with long-term future in the world in the company RUDIS, which is why one of our directions are also investments in renewable energy sources (RES).

In October 2023 RUDIS connected its 9 MW wind powerplant VE Alibunar I to 20 kV distribution network and supply the first MWh of produced electricity to the electricity network.

Power plant will generate from 27 to 29 GWh electricity per year, which suffices to supply 6.000 households.

RUDIS bought the company Balkan Electric doo Vršac in Serbia at the start of 2022. The company had the final building permit to build windfarm VE Alibunar 1 with three wind turbines with 3 MW rated power each. The municipality Alibunar lies approximately 50 km north-east from Belgrade in the area of South Banat with more than 80 % of wind potential in the Republic of Serbia.

Wind turbines, type WD164-3300 were supplied by the Chinese company Zhejiang Windey Co., Ltd., the sixth largest wind turbine manufacturer in the world. Basic information and main components of wind turbine:

• Rated power of wind turbine 3,3 MW
• Tower - height 97,5 m, consists of four segments, bottom diameter of tower: 4.800mm
• Nacelle weighs 116 tons and it is installed at the top of the tower, where the majority of technological equipment is installed
• Rotor with three 82 meters long blades, rotor diameter 164 m (total max height 179,5 m)
• Generator with rated power 3,3 MW (conversion of mechanical energy to electrical energy)
• Control system (in charge of rotating according to wind)
• Power transformer for conversion of voltage from 1140 V to 20 kV
• Middle voltage switchgear
• Supervisory control and data acquisition system for wind turbine (SCADA)

Wind turbines are connected to the existing 20 kV substation »Alibunar mini«, located circa 1000 meters away via common MV switchgear and cables.

Investment value amounts to EUR 15,522 million. 75 % of funds were provided by Nova Ljubljanska banka d.d. Ljubljana based on loan with maturity of 15 years. Own participation of the company RUDIS amounts to 25 % of investment value.

RUDIS in full performed, coordinated and managed all required activities for construction of power plant, from selecting and supplying equipment, managing works on site, installation of equipment and coordination of obtaining required consents and permits.

All energy produced from the wind power plant is bought by the company PLC Interenergo d.o.o., Beograd on the basis of long-term power purchase agreement. PLC Interenergo d.o.o., Beograd included the power plant in its balance group Interenergo - Kellag and performs balancing energy.
