Natural gas

Slovenia depends almost entirely on natural gas supplied from abroad. 

The Slovenian gas transmission network consists of 1,121 km of pipelines. An important part of the transmission network are compressor stations in Kidricevo and Ajdovscina, which maintain the required pressure in the transmission network. 

The central part of the Slovenian gas network includes the main pipeline (M1) from Ceršak to Rogatec, (M2) from Rogatec, via Podlog, to Vodice, and (M4) from Rodne to Novo mesto, with a nominal pressure of 50 bar, and the main pipeline (M3) from Šempeter pri Novi Gorici to Vodice, with a nominal pressure of 67 bar. The above-mentioned connections of the transmission network ensure a reliable supply with natural gas to Slove

The Slovenian gas network is part of the pan-European gas transmission system. The connections of the Slovenian pipeline system with the neighbouring countries of Italy, Austria and Croatia are one of the advantages of Slovenia’s geographical position. 


Connecting to the gas network

Making a connection to the gas network is a task of the system operator. The customers wishing to connect to a gas distribution network have to obtain a connection approval from the distribution system operator in the area in which they live, or in which the building requiring a network connection is located. nia.

The market of natural gas

In line with the liberalisation of the natural gas market in the European Union, Geoplin's subsidiary Plinovodi took over management of the natural gas infrastructure, and performs the activity of natural gas transmission network system operator (TNSO). To the Slovenian gas transmission network different natural gas distribution networks are connected, through which DNSO (company Plinovodi) facilitate the distribution of natural gas to 72 Slovenian municipalities. In terms of distribution networks, a DNSO performs similar tasks to those performed by the TNSO on the gas transmission network.

Prices of natural gas in Slovenia 

The gas prices for eligible customers are set by the market and are the subject of negotiations or agreements between the suppliers and eligible customers.

The final price for the supply with natural gas consists of three elements

  • the price for the use of the networks  
  • the price for the natural gas 
  • the excise duties, the value-added tax, and other taxes (CO2 tax and contribution to improve the efficiency of energy use).

Water distribution and sewage collection and disposal

The public services of the supply with water intended for human consumption (drinking water) and collection and disposal of waste water and meteoritic water is carried out by public companies on the basis of authorities granted by local communities. These mandatory economic services are operated by using the public infrastructure under their management.

For every new services (utility) connection or a modification to the existing one it is necessary to apply to the operator of the service for approval. The approval to connect to the service is issued on the basis of a previously prepared house connection drawing made by the public company against a fee.

Charges for drinking water service 

The quantity of water used is the basis for billing consumers on a monthly basis. In addition, the charge for the water service and the network charge are included in the bill based on the scale of the water meter plus the 9.5% value-added tax (VAT).


Charges for services provided to industrial customers 

The methodology for the collection and separation and purification of industrial effluents/waste water, processing of liquid waste and sludge is adjusted to the profile of the industrial consumer. Industrial customers are entities discharging over 4,000 m3 of effluent/waste water annually and/or are payers of the fee for monitor industrial waste water due to the nature of their activity. Industrial effluent/waste water means additional load on municipal waste water (sewage) treatment plants. Public companies enter into contracts with industrial customers to collect and treat effluents/industrial waste water and the charge for this waste water service is calculated in line with the approved methodology for a particular public company.

Charges for waste water 

Sewage fee is also charged on the basis of the water supplied. On top of the base fee for collection, treatment, cleaning and discharge of waste water as well as the environment load tax (depends on quantity of waste water discharged to the sewage system), network charge and 9.5% VAT are added.

Waste managment

Rising incomes and population growth are putting pressure on water supplies and generating more waste. When Slovenia became a full-fledge member of the European Union, its legislation governing the environment protection had to be fully compliant with the EU legislation including special waste and dangerous substances management. Every small, medium-sized and large enterprise that engages in a specific activity where waste dumped without taking special measures could harm the environment, must take adequate waste management steps.

Charges for disposal of municipal waste

The public service of disposing of waste is carried out by companies on the basis of authorisations granted by local communities.  

Disposal of discharge of solid waste is billed on the basis of quantity (usually in cubic metres - m3) of waste in by taking into account the number of disposals per month. For the companies producing hazardous waste, special regulations apply.
