After the third ice age, the current territory of Elektrėnai was flooded by glacial melt waters. Over time, the water moved, leaving clay and sand alluvium in the highlands, and several lakes in the valleys. Thus, after three hundred years, Anykštos, Pukinnos, Jagudis and several smaller lakes remained. People have been talking about the mentioned lakes since the Stone Age. This is evidenced by the burial mounds of Alynka, Perkūnakiemi, and Gojaus explored in these surroundings. Archaeological excavations show that one of the Jotving tribes lived here at the beginning of our era. In the early years of the existence of the Lithuanian state, the old inhabitants of the Elektrėnai area found themselves under the influence of one of the most important administrative and political centers - Trakai. The great roads of that time to Vilnius and Traky passed through these places, which were often used by the troops of the Teutonic Order. In 1348, a dozen kilometers from the current city of Elektrėnai, by the river Streva, a big battle took place in which thousands of people died, including Gediminas' son Narimantas. So our ancestors were witnesses of important events. People settled near rivers and lakes because they needed water first. The selected location needed a name. The old Lithuanian religion, natural phenomena, historical events, and the names of famous people helped here. Relic of Paganism - Thunderbirds. This is the territory where the Lithuanian Power Plant is located today.
People have been living in the current territory of the city of Elektrėnai and its surroundings for a very long time, although the city itself is one of the youngest in Lithuania. From the 14th century, the areas of Elektrėnai were under the influence of the Duchy of Trakai, from 1413 – Trakai Voivodeship, after the restoration of Lithuanian independence (1918) – passed from Trakai County to Kietaviškiau County, later to Vievi County and Vievi District (June 20, 1950). The city of Elektrėnai, which had already been established, belonged to the Trakai district, and in 2000, after the establishment of the municipality of Elektrėnai, it became its center. Electric constructions have brought great changes. The body of water, now called Elektrėnai Lagoon, was created by damming the Streva River. In 1961, the water began to rise in the dam, merging as many as eight lakes and small lakes: Anykšta, Pukina, Jagudė, Jagudėlė, Dumbliuka, Nendrynėlė, Syšvanta and Šyšvantaitis. The old islands, even the famous Stork Colony, the largest homeland of white travelers in Europe, were under water. New islands appeared: Didžioji, Baubii, Garnii, Kiri, Miškinė, Zalioji, Kalvotoji... Kakliniškii, Perkūnakiemi, Šarkinė, Anykščiai, Raistinė, Lekavičių, Mažiklė, Petravičių, Alinka, Runga villages, including more than 140 homesteads. moved, appeared under water. The names of these villages are engraved on one of the sculptures of the Elektrėnai Sculpture Park. in 1961 in the spring, construction of a permanent settlement began, the city was designed by B. Kasparavičienė and K. Bučas.
