INTERENERGO d.o.o. za trgovinu i usluge

INTERENERGO d.o.o. za trgovinu i usluge is a Slovenian energy company that operated for more than two decades as the Interenergo Group, the South-East Europe platform of the Austrian Kelag Group. Its business spans the investment, construction and management of renewable power plants — hydropower, wind and solar — as well as short- and long-term electricity trading and energy management services such as PPAs and green energy products. Through its parent structure it is active across 14 European markets, with a particular focus on the Iberian, Mediterranean and South-East European regions. The company's roots lie in the SEE region, where it built a reputation as an experienced and trustworthy partner in energy. Its portfolio includes renewable projects across Europe, with installed capacity and annual production figures reported by its parent group. Beyond generation, Interenergo has been active in electricity trading across more than 15 European wholesale markets and on multiple energy exchanges, and it provides energy solutions for industry and the public sector. In 2026, Interenergo and other international subsidiaries of the Kelag Group underwent a renaming process, adopting the Kelag International name and unifying under one brand. The legal entity INTERENERGO d.o.o. za trgovinu i usluge therefore represents the historical and legal continuation of the Interenergo business within the Kelag International structure. Its strategic orientation is aimed at selective growth in hydropower, wind power and photovoltaics, as well as energy services, in its three focus regions.

Interenergo began operating in the South-East Europe (SEE) region as the Interenergo Group for more than two decades, establishing itself as an experienced, efficient and trustworthy energy partner. It formed part of the international operations of the Austrian Kelag Group, which has more than 100 years of tradition in the energy industry. Over the years, the company built a portfolio of renewable energy projects across Europe, including hydropower, wind and solar facilities, and developed complementary activities in electricity trading and energy management. Its parent group reports renewable projects across Europe with installed capacity and annual production figures, and trading on multiple energy exchanges and more than 15 European wholesale markets. In 2026, Interenergo and other international subsidiaries of the Kelag Group underwent a renaming process, adopting the Kelag International name and unifying under one brand. This rebranding consolidated the group's international operations — covering the Iberian, Mediterranean and South-East European regions — under a single identity, while the legal entity INTERENERGO d.o.o. za trgovinu i usluge continued within the structure.
