Fourteen years later, the first electric lighting in Serbia was furnished in the military office building in Kragujevac.

[9] In 1900, the first alternating current hydroelectric power plant Pod gradom in Užice on the river Đetinja went online.

The first alternating current transmission line from hydroelectric power plant Vučje to Leskovac, with the length of 17 kilometres (11 mi), went online three years later.

Twelve years later, the pumped storage plant Bajina Bašta was built, and in 1990 the hydroelectric power station Pirot was put into operation.

[15] However, all these employees are not working in Kosovo-based power plants, and are only occasionally and indirectly employed by EPS throughout the rest of Serbia.

Then, the electric power transmission division of EPS was split from the company and established as its own public enterprise, named Elektromreža Srbije (EMS).

Since 1 January 2013, the Serbian electricity market has been open to other companies with the expectations to be completely liberalized in the coming years.

Allegations were related to RB Kolubara (EPS's subsidiary) management which was found to be implicated in a number of different schemes involving equipment procurement and leasing and the sale of coal.

[28] In April 2014 the Organized Crime Prosecutor has issued an official order for the police to look into the allegations about possible wrongdoings at the EPS.

The allegations were based on the report of the Anti-Corruption Council which showed discrepancies in the quantities of electricity imported and exported by EPS from 2010 to 2012.
