Cibuk 1, a 158MW onshore windfarm, is being developed by Vetroelektrane Balkana or Wind Energy Balkan Group (WEBG), in Dolovo, Serbia. It is expected to become the biggest commercial windfarm in the country and the Western Balkans.
WEBG is entirely owned by Tesla Wind, a 60:40 joint venture between Masdar and Cibuk Wind Holding, a subsidiary of US-based developer Continental Wind Partners (CWP).
Construction on the €300m ($354m) project began in 2015 and the plant is expected to become fully operational by 2019. It is expected to provide electricity to approximately 113,000 homes and offset more than 370,000t of carbon dioxide emissions a year.
Thewindfarmis expected to create 400 jobs during the construction phase.
Location of the Serbian windfarm
Čibuk 1 is being built 50km north-east of the Serbian capital, Belgrade, in the Kovin municipality, Dolovo, Vojvodina.
The municipality of Kovin was selected after carrying out a number of environmental studies. The location offers an optimal combination of wind potential, good road and grid access, low environmental impact, and accessibility of adequate infrastructure.
Cibuk I plant make-up
The Cibuk 1 windfarm will cover an area of 37km² and will be installed with 57 wind turbines with a rated capacity of 2.78MW each. The location of the turbines has been optimised to increase generation capacity and decrease the impact on the local environment.
The maximum height of each turbine is 180m, including the tower and the blade radius. Each turbine has three blades with a rotor diameter of 120m.
Eachturbinewill be fixed to a concrete base measuring 19m in diameter and 3m in thickness. The base will be reinforced by 25 concrete piles, which will be 16m-deep and 0.6m in diameter each.
“It is expected to provide electricity to approximately 113,000 homes and offset more than 370,000t of carbon dioxide emissions a year.”
The operational lifespan of the windfarm is expected to be 25 years.
The turbines will be connected to a transformer within the site boundary by means of underground power cables.
A new 400kV overhead high-voltage power line will connect the transformer station to the existing 400kV transmission line.
The environmental impact assessment for the project was conducted by Atkins.
General Electric (GE) is supplying the wind turbines and is also responsible for the construction of the windfarm. The contract also includes a 15-year full-service agreement.
GE subcontracted CJR Renewables to design the windfarm and perform civil works such as the construction of roads and turbine foundations.
Two International financial institutions namely European Bank for Reconstruction and Development (EBRD) and the International Finance Corporation (IFC) are together providing €215m ($253.7m) for the project.
Power purchase agreements
The power generated by the Cibuk 1 windfarm will be sold under a 12-year power purchase agreement (PPA) signed with a subsidiary of Elektroprivreda Srbije (EPS), a state-owned power company, in October 2016.
Benefits of the new windfarm
Serbia has set a target to meet 27% of its power consumption needs fromrenewableenergy sources by 2020. Cibuk 1 will help the country in achieving the goal, while also reducing the need for importing energy from the neighbouring countries.
It will also reduce the country’s dependence on fossil fuels for power generation and reduce greenhouse gas emissions.
