110kV Switchyard at Doblar Hydroelectric Power Plant

February 2025:

As part of the reconstruction and new construction of the 110 kV switchyard at the Doblar Hydroelectric Power Plant, we signed a contract with the company Kolektor Igin for the supply and execution of all auxiliary power systems within the switchyard. The scope of the auxiliary power system includes:

  • AC auxiliary power distribution boards,
  • Distributed AC auxiliary power distribution boards,
  • 220VDC auxiliary power distribution boards,
  • 110VDC auxiliary power distribution boards,
  • Rectifier,
  • Inverter,
  • Battery banks,
  • Diesel generator,
  • Auxiliary power cable connections.

The works at the site will be carried out in phases, as both Doblar 1 and Doblar 2 HPPs and the 110 kV transmission system will remain in operation. The project is expected to be completed in the first quarter of next year.

 
Provision of Services During the Overhaul of Unit 6

February 2025:

In February 2025, we signed multiple contracts with the client Thermal Power Plant Šoštanj (TEŠ) for various service packages to be carried out during the overhaul of Unit 6, scheduled for this year.

The planned scope of this year’s overhaul includes work on major technological unit systems, flue gas cleaning, and common facilities, specifically: boiler systems, turbine systems, post-combustion systems, flue gas cleaning systems, by-product management systems, and common plant systems.

Unit 6, recognized as the most advanced thermal energy production unit in this part of Europe, generates approximately one-third of Slovenia's total electricity production annually. The overhaul will be essential for ensuring the reliable and efficient operation of Unit 6 in the coming years. With carefully executed maintenance and upgrades to individual systems, the power plant will continue to operate with a high level of reliability, while also complying with stringent environmental and technological standards. This will enable Unit 6 to remain a key contributor to the stable and secure electricity supply in Slovenia.

Signing of the construction contract for the project Modernization of the water supply system - Phase I: Upgrade of the filter unit at the Hrib reservoir

November 2024:

With the mayor of Moravče, dr. Balažic Milan, on November 12, 2024, we signed a construction contract for the project entitled "Modernization of the water supply system - Phase I: Upgrade of the filter unit at the Hrib water reservoir". The project covers the construction of a filtration facility, including external arrangements (landscape), architectural arrangements, electrotechnical installations, mechanical installations, and all associated technological equipment. During heavy downpours, the turbidity of the water in the well increases, so the project envisages the construction of a filter unit with sand filters, which will have a total capacity of 20l/s. The new device will ensure constant quality of drinking water to its customers.
