KINDERGARTEN ŽALEC – WEST, a child and environment-friendly kindergarten
KINDERGARTEN ŽALEC – WEST, a child and environment-friendly kindergarten

February 2024:

In cooperation with the Municipality of Žalec, the new construction of the almost zero-energy kindergarten Žalec West was successfully completed, which represents an important step in terms of the sustainable development of the local community of Žalec. The goal of the project was to establish a modern, 9-department kindergarten that not only serves its basic purpose, but also uses renewable energy sources.

The new construction of the kindergarten in Žalec will accommodate as many as 198 children of all three age groups, which is an important step towards improving the quality of life in the local community. In addition to the comprehensive arrangement of the building, the new structure will also include the arrangement of the surroundings, including access, parking and outdoor play areas.

The new almost zero-energy construction of the Žalec - West kindergarten is an example of excellent practice of sustainable urban development, which sets standards for the future and enables quality life for current and future generations.

Vrtec Žalec - West is a public-private partnership project with the Municipality of Žalec.

January 2024:

At the end of last year, we received the joyful news and in December signed a contract with the client ELES, d. o. o. for the project DTS 110/20 kV Gorica, Replacement of secondary equipment and self-use with electrical assembly and construction-craft works. The 110/20 kV distribution substation Gorica is designed as a distribution transformer substation. The 110 kV switchyard at DTS Gorica comprises of seven 110 kV transmission line fields, three 110/20/10 kV transformer fields for power transformers with capacities of 2x31.5 MVA and 1x20 MVA, coupling-measuring field and a grounding field. The specific feature of the 110 kV switchyard is the air-insulated design with dual-busbar system in a shielded gas version, along with a coupling-measuring field, grounding field and busbar disconnectors. All works must be completed by the end of 2025.

Happy new year 2024!

ESOTECH: Proud to be part of the GREEN TRANSFORMATION in our surroundings
Green transformation

November 2023:

At ESOTECH, we are proud of another project that is part of the restructuring of coal-mining regions – “Transformation of the District Heating System”. Together with the Municipality of Velenje, we will carry out the “Green Transformation” project, where key activities will be focused on the placement of newer – green and smart energy production sources that will be able to replace the heat produced from the Šoštanj Thermal Power Plant and take a step closer to reducing greenhouse gas emissions from thermal power plants using coal, from which heat is supplied via district heating to end users in our vicinity.

This transformation with this project includes photovoltaic power plants at DWTPs (drinking water treatment plants) Grmov vrh, ?ujež and Mazej, which were designed and built by ESOTECH. In addition to the mentioned facilities, this also includes the Pumping station Konovo photovoltaic power plant and the central WWTP of Šaleška valley photovoltaic power plant together with the battery storage and its integration into the existing electrical system.

Success in the field of green transformation will be brought about by the inclusion of a heat pump for the exploitation of heat-treated wastewater from WWTP Velenje, together with its integration into the existing thermal system of Šaleška valley.

A major breakthrough in the green transformation will certainly be the utilization of the water potential of the Doli? and Toplica springs, which are led through a common pipeline to the ?ujež drinking water treatment plant, which will result through the included new ?ujež hydroelectric power plant, with the aim of covering the own needs of the DWTP facilities for electricity.

With this project, we will demonstrate once again that nature and knowledge can work hand in hand to create a better tomorrow.
