Transport system and nominations

The transport system is the basic system for the delivery of natural gas and forms the backbone of all other activities in energy supply.

Transport tariffs

In the Republic of Croatia we use the so-called Entry-Exit model for the transport system that is used in most EU countries. This transport system model entails the reservation, nomination of use and the calculation of the costs of using the system at entry points to the transport system, as well as at exit points from the system to the end users and other linked systems. You can find more about the transport system in the Republic of Croatia on the web-pages of the Plinacro Company.

In order to guarantee a high level of quality, reliability and safety, PPD provides its customers with professional consulting, planning and all other forms of support in the use of the transport system, and especially with respect to the assignment of transport capacity.


Every buyer is obliged to provide prenominations for natural gas for each working day. A prenomination represents a form of order for natural gas for the following day or days. Each buyer is obliged to deliver his prenomination for each of the exits from the transport system and for each hour of the day no later than the agreed time for the following day or days. Upon sending the prenomination, the customer gains the right to the nominated quantity of natural gas in the event that it is within the framework of the already reserved transport capacity, and PPD is under the obligation to ensure that quantity of natural gas to the buyer. The buyer places his prenomination via computer, using the interface on the PPD portal or via email, sending an official prenomination form.

Transport capacities

In dealing with natural gas and transport it is essential to take into account transport capacities. Transport capacities represent the physical limitations of the media through which natural gas is moved. In Croatia, this medium is the transport system made up of a line of underground and surface pipelines. For the sake of safety, reliability and quality in the supply of natural gas, it is essential to reserve transport capacities for each day, month or year.

Transport capacities are charged to customers in line with the current transport pricelist and the methodology of calculating natural gas transport costs adopted by the Operator of the transport system in the Republic of Croatia. In the event that there is a deviation from the reserved transport capacities, the buyer is placed in the unfavourable position of having to pay penalties in line with the deviation.

Cost calculation

The calculation of the cost of natural gas transport is made in several segments, and this is defined by the regulatory body, namely the Operator of the transport system in the Republic of Croatia.

The cost is primarily made up of fees for the entry of natural gas into the transport system, for exiting the transport system, as well as for the reserved capacity, and finally on the basis of the actual received amount of natural gas. Naturally, the calculation also includes the price of natural gas as an energy source that PPD offers its clients.
