Trebinje 1 Hydroelectric Power Station

The Trebinje 1 hydroelectric facility is built around the Grančarevo arch dam, which spans 439 meters across the Trebišnjica River and rises 123 meters high. Inside the machine hall, three Francis turbines operate together to produce electricity, generating between 370 and 420 gigawatt-hours each year.

Construction finished in 1967, establishing what became the largest water reservoir by volume in the country. This completion transformed the region's capacity for both power generation and water management.

The power station holds significance as a major source of electricity that shapes life in the region today. People recognize it as a symbol of engineering achievement that has connected communities across borders through energy supply.

The dam features a walkway that offers good views of the river and surrounding landscape for visitors to explore. Summer months provide the best conditions for a visit, with warm and clear weather typical of the region.

The facility includes two water evacuation outlets, each 2.5 meters in diameter, designed to handle water release from the reservoir. These openings reveal how engineers prepared for emergency situations and managing high water levels.
