Bosnia and Herzegovina runs one of Europe's most distinctive small power systems: roughly two-thirds of generation comes from lignite and a third from hydro, demand peaks in winter, and the grid is interconnected with Croatia, Serbia, and Montenegro. Despite headlines about record import costs, the physical balance tells a different story — measured at the borders, BiH has been a net exporter in nearly every month of the past two years. The import-bill spikes reflect expensive winter hours, not a year-round deficit.
