The debt tradition has begun for almost a century after only 28 years since the construction of the world's first electric power plant, which was built by famous American inventor T. A. Edison in New York.

With that, Montenegro was ranked in the line, at that time, of rare European and world countries whose towns were illuminated by electricity.

Everything started on August 19, 1910, when, in connection with the crowning of Nikola I Petrović, in Cetinje, the first electric power station in Montenegro was put into operation.

The power plant served to illuminate the Dvor, Zetski dom, the main street of the city and several houses of the more prominent Montenegrins.

The building and facilities of the "Montenegrin Electric Company", as originally called the Cetinje power plant, are preserved and, because of their exceptional importance, they were placed under the protection of the Law as a cultural monument, in order to be transformed into the EPCG museum on November 13, 1976, with a proposal to grow in the Technical Museum of Montenegro.

The date of commissioning of the electric power station, August 19, is celebrated as the day EPCG AD Niksic.

Shortly after the commissioning of the Cetinje mini-power plant, other power plants started to open in Montenegro, and other towns and citizens in Montenegro started to enjoy the advantages of electricity brought by them - Bar in 1913, Kotor in 1916, Herceg Novi in 1925, Podgorica and Niksic in 1927, Risan in 1928, Kolasin in 1929, Ulcinj in 1930, Zelenika in 1935, Perast in 1936, in Pljevlja in 1937, in Tivat in 1939 and so in a row.
