Kaunas Hydroelectric Power Plant

Kaunas Hydroelectric Power Plant (Kaunas HPP) is one of the largest power plants in Lithuania, which generates green electricity using the potential energy in water. It can quickly react to the demand in the electricity network. Four hydraulic turbines convert flowing water into green electricity at the hydroelectric power plant built on the river Nemunas. Kaunas HPP generates around 4% of the total electricity consumed in Lithuania annually and is critical for ensuring the stability of the national energy system.

Key facts

The total capacity of Kaunas HPP is 101 MW with 4 units, 25 MW each. 

Four hydraulic turbines with adjustable blades turn the generators.  

When the power plant is operating at its full capacity, the water flow through a single turbine increases up to 158 m³/s and to 632 m³/s through all turbines. 

The maximum increase in water level after damming is 24.6 m, the length of the pressure front is around 1.5 km, the average perennial stream is 259 m³/s, and the water flow under normal conditions is 3,030 m³/s.
