The Ladce hydroelectric power plant is the oldest operated hydroelectric power plant on the Váh river - in service since as early as 1936. It was built however at the time that the electrification was only getting off the ground and electricity supply demands were low. As a result, it was designed to a low flow rate - 120 m3.sec-1. All of the downstream and upstream HPP´s alike have a higher maximum usable flow, therefore the Ladce HPP constitutes a so-called bottleneck on the Váh river. Over the period between 1999 and 2001 the Ladce HPP had been reconstructed up to a flow rate of 2 x 90 m3.sec.-1, thereby also raising its installed capacity from 13.8 MW to 18.9 MW.
