Development projects

The HSE Group has concluded investments in coal technologies, namely in generator 6 of the TEŠ, which complies with the international standards of best available technologies with planned operation until 2054, and generator 5 of the TEŠ, which, after ecological rehabilitation and revitalisation, is expected to operate until 2030 as a reserve generator for generator 6 during maintenance or overhaul or during favourable market conditions.

At the moment, a major part of investments are those in reliability of production and in reconstruction. In the next three-year period, we are preparing an overhaul of generator 5 (2022) and generator 6 (2021) of the TEŠ, renovation of secondary systems of three hydro power plants on the Drava River (2020–2022) and reconstruction of the Formin Hydro Power Plant (2024–2025). Renovation of the Avče Pumped Storage Plant started in 2018 and will take until at least the first half of 2019.

The HSE Group is constantly looking for new, additional projects and investments in order to ensure safe, reliable, competitive and environmentally friendly long-term supply of electricity in Slovenia. We are putting an emphasis on building production facilities which pursue to the greatest possible extent the objectives of the climate and energy package, while at the same time maximising the economic and minimising the environmental impact.

HYDRO POWER PLANTS ON THE MIDDLE SAVA RIVER

HSE is the concessionaire for the energy exploitation of the Sava River in the area between Medvode and Zidani Most. In 2018 talks were relaunched with the authorities to harmonise a concession contract. The construction of all ten planned hydro power plants on the middle Sava River would increase the installed power of hydro power plants on the Sava by 300 MW, and 1 TWh of electricity from renewable sources would be gained, which is currently almost 10% of total electricity produced in Slovenia.

RENEWABLE ENERGY PROJECTS

  • Construction of small hydro power plants in the basins of the Soča and Drava.
  • The Ojstrica wind farm and examining the possibility of building wind farms in Paški Kozjak and Rogatec.

RENOVATION OF SLUICES

The operational capability of sluice gates is of key importance for the safety of hydro power plants and flood safety, which is why we have been making continuous investments into renovation of sluices and renovation and overhaul of sluice gates and their drives.

ENVIRONMENTAL PROJECTS

In the light of the EU commitments taken by the Republic of Slovenia regarding the reduction of greenhouse gas emissions along with the implementation of measures for efficient use of energy and increase of the share of renewable sources, the HSE Group dedicates a lot of attention to the development of environmental projects which we implement in accordance with the existing legislation, and which reduce the environmental impact of the existing energy facilities:

  • Construction of fish ladders and revitalisation of fish population, which we implement on the basis of the Water Directive and the National Water Management Plan (NUV 2);
  • Removing sludge and maintaining energy potential of reservoirs: maintaining the energy potential of reservoirs of the chain of hydro power plants on the rivers Drava and Soča is a continuous process as part of which a useful volume and level of water, and consequently, flood safety, is maintained in the reservoirs of the chain of hydro power plants on the Drava and Soča. As part of these activities, we meet the obligations from the concession contracts for the exploitation of the rivers Drava and Soča for the production of electricity, such as regular removal of deposits, regular maintenance of the riparian area and others.
