Krivaca is a 105MW onshore wind farm being developed in the Branicevski district of Serbia, around 150km east of Belgrade. The project will be spread over an area of 242ha across the municipalities of Golubac, Kucevo and Veliko Gradiste.

Ivicom Energy is the developer of the project, while MK Group, a Serbian investment company, and ALFI Green Energy Fund, an investment fund focused on energy projects in the Western Balkans region, will operate the wind farm.

Once operational, the wind farm is expected to generate 310GWh of clean electricity a year, which will be equivalent to 1% of the total annual electricity consumption of Serbia. It is expected to have an operational life of 25 years.

Three environmental impact assessments (EIAs), including one for the wind farm and two for the overhead transmission lines to transport power from the site, were conducted for the project.

Construction of the Krivaca wind farm started in 2021, with commissioning scheduled for the end of 2023.

The project’s objective is to increase the supply of electricity to Serbia’s national grid, as well as diversify the country’s power generation mix.

Krivaca wind farm make up

The onshore wind farm is located across the municipalities of Golubac, Kucevo and Veliko Gradiste in eastern Serbia. It will be comprised of wind turbine generators, cable lines, overhead transmission lines and an onsite substation.

As well as the onsite substation, the project will include a 110kV switchyard and two new double-circuit 110kV overhead power lines (OHLs).

An earlier plan included the installation of 38 wind turbines. This was later revised to 22 turbines.

Construction details

Construction will include 17.2km of access roads, 13.3km of service roads, an underground medium-voltage cable system and installation of transmission line bays at the existing Veliko Gradiste and Neresnica substations.

Phase one of the project involves the construction of 13km of roads, the on-site substation and the expansion of the existing substations at Neresnica and Veliko Gradiste. It also includes the development of a cable system for the future connection distribution plant (PRP).

Internal overhead transmission lines to connect the substation to the turbine clusters will also be built as part of the project.

Turbine details

The project will feature 22 N149/4.X turbines from the Nordex Group Delta4000 series, which have a generating capacity of 4.8MW each. The wind turbine generators are planned to be installed in three areas, forming a cluster.

Each turbine will have a diameter of 149.1m, swept area of 17,460m² (187,938ft²) and maximum height of 180m.

A permanent storage building will also be built for the operation and maintenance of wind turbines at the site.

Grid connection

The electricity produced will be transported from the onsite substation to the Neresnica and Veliko Gradiste substations through two new 110kV transmission lines.

The transmission lines will have a length of 19.4km each.

Contractors involved

Nordex Group received a contract to supply the turbines for the Krivaca wind farm in June 2022. The contract also includes a 25-year premium service agreement for the turbines.

Elnos Group was awarded the balance of plant contract for the project. It will also connect the wind farm to the electricity network.

GEOING GROUP conducted detailed engineering-geological and geophysical studies for the project between August and November 2014.

Global consultancy firm Mott MacDonald prepared the Environmental and Social Impact Assessment (ESIA) addendum for the project in March 2018. The company was engaged to prepare the report as support for International Finance Corporation’s financing of the Serbian wind farm.
