The need to provide additional high-voltage electricity transmission capacity from Bosnia and Herzegovina (Banja Luka) to Croatia has long been recognised, and the construction of this line would greatly improve the potential for electricity trade between the two countries. This new line will also enhance regional grid stability, and assist in the development of renewable energy resources in the region. Such a strong network will support other infrastructure development projects, for example, new railway electricity substations for supplying a modernised railway line Zagreb-Rijeka, and, in the long term, further strengthening of the transmission grid by upgrading the 220 kV lines towards Zagreb and Rijeka.
A WBIF €1.5 million grant has been used to develop a Feasibility Study, including the Environmental and Social Impact Assessment and a Cost-Benefit Analysis.
