Krka National Park lies within Šibenik-Knin County, and covers a total area of 109 km² of the loveliest sections of the Krka River, and the lower course of the Čikola River.

The national park is a vast and primarily unaltered area of exceptional natural value, including one or more preserved or insignificantly altered ecosystems. The purpose of the park is primarily to serve science, culture, education and recreation, while tourism activities have also been introduced for its visitors.

Including the submerged part of the river at the mouth, the Krka River is 72.5 km long, making it the 22nd longest river in Croatia. It springs in the foothills of the Dinara mountain range, 2.5 km northeast of Knin. With its seven waterfalls and a total drop in altitude of 242 m, the Krka is a natural and karst phenomenon. The travertine waterfalls of the Krka River are the fundamental phenomenon of this river.

At the end of the 19th century, before any of the other world metropolises, Šibenik received electrical street lighting. On 28 August 1895, the first complete alternating current electricity system in Croatia was put into operation.This was a complete system of generation, transmission and distribution of multiphase alternating current, consisting of the Krka hydroelectric plant at Skradinski buk, the power longlines from the Krka River to Šibenik, and then to the customers in Šibenik.

Hydropower plant Krka was the second such hydropower plant in the world. The first was build on the Niagara river by American Forbes, based on Tesla’s design and patent only two days before HPP Krka.

In 1913, the work of the old hydroelectric plant was ceased on the basis of a contract, and at the start of World War I, the military authorities dissembled the plant in the old Krka hydropower plant and the two copper power lines to Šibenik to use these materials for the war effort.

1904 hydropower plant Jaruga 2 was put into operation (consisting of two Francis turbines total power of 7.2 MW), which is still operating today.

We at TEKUM are proud to had the opportunity to inspect and assess the condition of one of the oldest hydropower plants in the world.
