Natural gas market and infrastructure

Being one of the few European countries with own natural gas resources, Croatia is less dependent on gas imports than the other countries. The total gross inland consumption of natural gas is 102,150 TJ (2009), of which 64% is covered from national resources. The residual amounts are imported from Russia (34 %) and a minor percentage from Italy and Slovenia (2 %). Similar to the other countries, in Croatia the natural gas pipeline system is divided into the transportation grid, operating at about 50 and to 70 bar, and distribution grid, which operates at a middle and low pressure levels.

Relevance regarding the energy supply system

Relevances regarding the energy supply system of Croatia is for example the large share of water power. Total installed electricity capacity (2010, source: HEP Proizvodnja): 3,654 MW

  • Hydroelectric: 58%
  • Thermal (including cogeneration: 42%

Contributing more than 50 % to the national power generation, water power takes a predominant role in Croatia’s energy mix. However, also natural gas is of increasing significance for the country’s energy supply. In 2010 almost one third (29.3 %) of the total primary energy supply and 13.05 % of the electricity production were derived from natural gas. The total primary energy supply in Croatia was 409.08 PJ in 2006. RES other than fuel-wood and hydropower represented 0.06% of the total supply. Total electricity generation in 2010 was 13,272 GWh, 74% of the total domestic demand. Croatia’s potential for electricity generation from biogas is estimated at 90 MWel from agriculture and about 60 MWel from food industry. As of now there are no particular targets set for 2020 by the national government, but according to the national strategic documents, there are intentions to utilise the existing biogas and biomethane potential.

Gas grid infrastructure data
The transportation grid is operated by one TSO company, which is a 100% state-owned while the distribution grid  operate 39 private companies for distribution of natural gas, town gas and LPG. The natural gas transmission system comprise 2,034 km of pipelines, 142 exit metering-reduction stations with 210 metering lines and 19 entry metering stations. Regarding distribution level the total gas pipeline length sums up to 15,980 km. There is a uniform gas quality in the whole country. Gas is odorized in the distribution grid. The supervising authority in charge of the natural gas market regulatioin is Croatian Energy Regulatory Agency (HERA).

CNG infrastructure data

Natural gas plays a minor role in transportation. There are about 200 vehicles that run on natural gas in Croatia which is about 0,01% of the total number of cars and trucks in the country by end of 2010. There are two filling stations offering CNG in Croatia, one located in Zagreb and the other one in Ivanic Grad.
