Sustainable energy for our future.

The GEN Group seeks to build a secure, low-carbon and competitive energy future for Slovenia. We are working towards expanding the use of clean electricity generated locally, which has the potential to replace over time the electricity generated from imported fossil sources.

Strategic development schemes and investments that will make a vital contribution towards this end have been put in place, focusing on:

  • the continuation of the construction of hydroelectric power plants on the lower course of the River Sava,
  • the continuation of the technological modernization of NEK,
  • the replacement of gas turbine units at TEB,
  • the preparations for the construction of hydroelectric power plants on the middle course of the River Sava, and
  • the planning and preparations for the construction of a second nuclear reactor unit of Krško Nuclear Power Plant (JEK 2).
Maintenance & Upgrades

On account of regular maintenance and ongoing capital investments, our power generation facilities boast high levels of availability and operational reliability. In 2019, we invested a total of EUR 100 million in projects closely aligned with our values and mission.

The central focus was on investments in Brežice HPP, technological modernization and safety upgrades at NEK, replacement of gas turbine units at TEB, research for the JEK 2 project, and other capital expenditures essential for ensuring trouble-free operation.


NEK follows the strategy of continuous investment in technological upgrades and updates. The concept of investment planning for a five-year period has been introduced, with average annual investments in technological upgrades amounting to around EUR 35 million.



SEL ensures the regular investment maintenance of its facilities and development in the field of aquatic energy. In the year 2018, EUR 4.26 million of assets from depreciation and other own resources were earmarked for investments and development.



HESS is currently engaged in its biggest, core project: the construction of five hydroelectric power plants (HPPs) on the lower course of the Sava River.



In the year 2018, EUR 6.98 million was earmarked for the investments and development of TEB. The most important and comprehensive project of TEB is the replacement of gas blocks 1-3. At the end of March, an internal technical inspection and an expert technical inspection were completed, the latter being conducted by the issuer of the building permit, the Ministry of the Environment and Spatial Planning.



GEN-I earmarked EUR 4.19 million for investments and development. The majority of funds were allocated to information technology, which is necessary for the smooth operation of marketing and sales applications and for other fixed assets that are necessary for the company's operations.
