The Tiszalök Hydroelectric Dam is the result of the meeting between the forces of nature and human engineering expertise. It plays a key role not only in water management but also in flood protection, energy production, and navigation in Northeastern Hungary. Its comprehensive reconstruction was carried out using European Union funding.
What is the Tiszalök Hydroelectric Dam? Located at the 518th river kilometer of the Tisza River, this hydroelectric facility consists of three main parts. On the left bank, the hydroelectric power plant harnesses the river’s energy with three turbines. In the center, the weir regulates the water level through three openings, while on the right bank, the navigation lock allows ships to pass through. Additionally, auxiliary structures, bank protection systems, and various site facilities ensure smooth and efficient operation.
Why is this hydroelectric dam important? The Tiszalök Hydroelectric Dam plays an essential role in managing the waters of the Tisza River. The dammed water supplies the Eastern and Western Main Canals, enabling the irrigation of approximately 200,000 hectares of land in the Hortobágy region. It also contributes to water replenishment in the Körös Valley and serves as a backup drinking water source for Debrecen. But that’s not all! The dam also supports navigation, ensuring a Class III waterway from Tiszalök to Dombrád and from the mouth of the Bodrog River to the national border. Additionally, it plays a crucial role in flood control, managing ice-related floods, maintaining ecological water supply, and protecting water quality.
Why was the renovation necessary? The Tiszalök Hydroelectric Dam has served the region for decades, but over time, the deterioration of its structure made reconstruction increasingly urgent. Within the framework of the Environmental and Energy Efficiency Operational Programme, and with EU funding, the project reinforced critical structural elements to ensure the facility’s safe and efficient operation. Additionally, mechanical and electrical equipment was refurbished, and the adjacent riverbed sections were dredged. The modernization also improved the efficiency of the hydroelectric plant and reduced flood risks—both crucial factors given the increasing frequency of flash floods caused by climate change. Beyond ensuring the facility’s long-term reliability, the renovation contributes to environmental protection, sustainable energy production, and the economic development of the region.
The development was implemented from EU funding in the project KEHOP-1.3.0-15-2015-00009 under the Environmental and Energy Efficiency Operational Programme.
