The plant was founded in 1949 in the town of Sofia under the name Vasil Kolarov. In 1997, Korean giant Hyundai Heavy Industries Co. privatized the Bulgarian company, and its name was changed to Hyundai Elprom Trafo JSC. A few years later, the company became recognizable in the market as Hyundai Heavy Industries Co. Bulgaria. In early 2020, Hyundai's manufacturing factory in Sofia became a member of BEZ International Group, known as one of the main manufacturers in the field of Transformers in Central Europe.
As of 01.08.2021 the Company officially changed its name to Elprom Heavy Industries AD.
The company's new name reflects Elprom's rich history and more than 70 years of energy experience. Our goal is to be the preferred brand in the energy sector. We think the technical requirements will increase, so we organize research and development and invest in the best equipment.
