The total water front length is 4480 m. Installed power is 1404 MW, designed average annual production is 3310 GWh, but actual annual production is 2100 GWh due to lowered reservoir level.

The power house has 18 generator units with Kaplan turbines, each 78 MW at 12.4 m head.

Flooded land included valuable meadows and several hundred acres ( hectares ) of oak forest that was not duly felled.

Rising normal water level to the design value of 68 m was hindered first by incomplete reservoir banks protection, then being opposed by Nizhny Novgorod Oblast and Mari El Republic.

Now the station is operating at 63 m water level, with an actual installed power of 820 MW and an average annual production of 2100 GWh.
