Croatian engineering firm Končar has successfully commissioned the Otočac small hydropower plant, contributing an additional 1.5 MW of renewable energy capacity to the national grid. This facility marks a significant step in enhancing Croatia’s renewable energy landscape, particularly in the realm of small-scale hydropower generation.
The Otočac plant is equipped with three generating units, each with a capacity of 500 kW, and is projected to generate over 7 GWh of electricity annually. This output is expected to bolster local renewable energy production and aid in advancing the development of small hydropower projects across the country. The completion of this project follows a comprehensive process that included construction, testing, and final commissioning phases.
A key innovation at the Otočac facility is the implementation of prefabricated generating units, which facilitate easier installation and lower maintenance needs throughout the plant’s operational lifespan. Končar has prioritized sustainability from the initial design stage, selecting equipment that can be recycled once it reaches the end of its operational life.
The electrical infrastructure for the plant is centralized within a dedicated control building adjacent to the powerhouse. This includes essential components such as medium-voltage switchgear, transformers, frequency converters, low-voltage systems, direct current distribution networks, and sophisticated control and automation technologies.
This project underscores Končar’s active participation in the regional hydropower sector, reinforcing its role in providing and integrating equipment for smaller renewable energy initiatives. As Croatia continues to expand its renewable energy capabilities, projects like the Otočac SHPP are vital for achieving long-term sustainability goals.
