Ugljevik III lignite power plant, Bosnia and Herzegovina

Ugljevik III near Bijeljina in the Republika Srpska part of Bosnia and Herzegovina is planned to consist of 2x300 MW units which would take lignite from the open cast mines at Delici, Peljave-Tobut, Baljak and part of Ugljevik-Istok. An existing unit of 300 MW at the site, operating since 1985, sits alongside the half-built Ugljevik II whose construction was never finished, and which is now the subject of a long-running dispute with Slovenia.

The new plant is promoted by Russian billionaire Rashid Sardarov's Comsar Energy and planned to be constructed by the China Power Engineering and Consulting Group Corporation (CPECC). China Development Bank representatives were present at the signing of an agreement between CPECC and the Republika Srpska authorities, indicating that the bank may be interested in financing, however this has never been confirmed.

The plant will have an extremely low net efficiency of 34.1 percent, compared to 40 percent as the best available standard according to the EU's 2006 reference documents.

Ugljevik III's Environmental Permit is being challenged in the Republika Srpska courts, and in December 2014 an official complaint was made to the Energy Community Secretariat because the environmental impact assessment is missing key information and that the data on likely emissions of SO2, NOx and dust are false.
