1870 - beginning of coal mining in Serbia, in the pit Stari Kostolac. Đorđe Vajfert was the owner of the mine. Due to investments into exploration mineral resources of Serbia, his name entered the history of Serbian mining. The Monument in Honour of Miners from Kostolac today stands in the place of the pit.
1884 - the first electrical illumination was introduced in Serbia in the section of Military Technical Office in Kragujevac, according to merit of engineer Todor Selesković. He was the first constructor of machines in Serbia and he constructed the first water turbine in Serbia.
1892 –Nikola Tesla visited Belgrade, for the first and only time. The citizens of Belgrade, but also people from all over Serbia prepared him a memorable welcome.
1893 – the first public power plant in Serbia was put into operation, thanks to a physics professor Đorđe Stanojević – thermal power plant was located at Dorćol in Belgrade. The beginning of electrification of Serbia is associated with his name - thanks to him, hydro power plants “Pod gradom”, “Vučje”, “Gamzigrad”, etc. were also put into operation – 6 October is the day when this thermal power plant was put into operation and today this day is concidered to be the Day of the Electric Power Industry of Serbia.
1894 – Đorđe Stanojević published the work “Nikola Tesla and His Inventions”. It was the first book about Tesla in Serbia and the second one in the world.
1896 - coal exploatation began in the pit “Tvrdojevac”,in Kolubara. For a long time in Kolubara pits, the coal wagons were drawn by - horses!
1900 – hydro power plant „Pod gradom“ in Užice on Djetinja river started operating, based on Tesla’s principles of alternating current, only four years after the start of operation of hydro power plant at Niagara Falls. The hydro power plant is still in operation..
1903 –on Vučjanka River, near Leskovac, the first hydro power plant “Vučje“ started operating. The first transmission line in Serbia, 17km lenght, was built from power plant “Vučje“ to Leskovac. The power plant is still in operation.
1908 - hydro power plant “Sveta Petka”, on Nišava River, near Niš, was put into operation. It is still operating today.
1909 – hydro power plant “Gamzigrad” on Timok River, near Zaječar, was built . It is still operating today.
1911- hydro power plant “Moravica“, on the river with the same name, in Ivanjica was put into operation. It is still operating today..
1928 - hydro power plant “Jelašnica”, on the river with the same name, near Vranje was put into operation. It is still operating today.
1931 - hydro power plant “Sićevo” was put into operation. It is located few kilometers downstream from the older HPP “Sveta Petka” on Nišava River, near Niš. It still produces electric energy
1932 – thermal power plant “Snaga i Svetlost” was constructed in Belgrade. It was one of the largest plants in the Balkans at that time.
1937 – the copmany “Elektro-Makiš” constructed the thermal power plant in Vreoci, that represented the backbone of Serbian electric power system of the time. Installed energy capacity of TPP was 12MW. The coal needed for the operation of this TPP was exploited at the pit “Junkovac”.
1943 – “Kostolac” the first open-cast mine was opened in Serbia; after the Second World War it had a significant role in the industrialization of the country, training of the staff and the implementation of new technology in the coal production. The mine was close in 1980.
1948 – the first hydro power plant constructed after the Second World War was HPP “Sokolovica” on Timok River, near Čokonjara
1948 - TPP “Mali Kostolac” was constructed. Mechanical equipment: turbines, generators and boilers, were brought from the old power plant in Belgrade (1893), partially reconstructed and installed in this power plant.
1952 – Open-Cast Mine “Kolubara” was put into operation. By including so called Field A in regular production the major manufacturing cycle in the production of coal began.
1954 - HPPs “Ovčar banja” i “Međuvršje” on Morava River, near Čačak were put into operation; the first kilowatt-hours of electric energy from HPPs “Vlasinske HE” were produced, which then represented a third of the total energy production in Serbia
1955 – HPP “Zvornik” , aka “firstling on Drina River” , was put into operation
1956 – TPP “Kolubara A” was put into operation in Veliki Crljani. Today it represents the oldest active TPP in EPS; coal exploitation on Open-Cast Mine “Kosovo” began
1960/1967 - HPP “Bistrica”, HPP “Kokin Brod” and HPP “Potpeć" were constructed
1962 –TPP “Kosovo A” was put into operation
1963 –the first units of CHP “Sremska Mitrovica” were put into operation
1966 –HPP “Bajina Basta” was put into operation; the Filed D was opened in Kolubara Basin, which was the largest open-cast mine at that time
1967 – TPP “Kostolac A” was put into operation
1969 –TPP “Morava” was put into operation
1970 –TPP "Nikola Tesla A" was put into operation – it is the largest TPP in the Balkans, and also the largest single producer of electric energy in the electric power system of Serbia
1970 –the operation of the hydro-power and navigation system (HEPS) “Đerdap 1” began – this is the largest hydro- technical facility on Danube River, and the biggest producer of hydro- power in Southeast Europe. It was designed and constructed with Romania, so that both countries have at their disposal the same, symmetrical parts of the main building, and its center line represents the state border
1978 –PSP “Lisina” was put into operation, with the function of pumping water from Lisinsko lake in Vlasinsko lake, which increased the production of HPP “Vlasinske ” significantly
1979 –HPP “Uvac” was put into operation, on the same lake, at about 1000 meters above sea level
1981 – the production of electric energy began in CHP “Novi Sad”
1982 - Reversible Hydro Power Plant “Bajina Basta” was built, the genuine jewel of Serbian electric power system
1983 –TPP “Nikola Tesla B” was put into operation. Two largest electric energy units in Serbia are in this plant; TPP ”Kosovo B” was put into operation.
1985 –HPP “Đerdap 2” was put into operation, the second joint Serbina and Romanian HPP on Danube River
1987 –TPP "Kostolac B" was put into operation
1989 –the most powerful unit of 120 MW in CHP "Zrenjanin" was put into operation
1990- Hydro Power Plant “Pirot” was built, unique by the surge which was built without anker stone blocks; the third CHP "Zrenjanin" was put into operation
1991- Public Enterprise PE Electric Power Industry of Serbia was established
1999 - during the NATO bombing, EPS electric power facilities suffered great damage
2004 - after a thirteen-year pause, the electric power system of Serbia was again connected with the first UCTE synchronous zone.
2005 - the activities related to electric energy transmission were spun-off PE EPS and two independent public enterprises are formed: PE“ Electric Power Industry of Serbia“and PE ''Elektromreža Srbije'' - Serbian Transmission System and Market Operator
2006 - from 1 January, Electric Power Industry of Serbia has been operating as a public enterprise with its 11 subsidiaries
