Energy in Croatia

Energy in Croatia describes energy and electricity production, consumption and import in Croatia.

Croatia satisfies its electricity needs largely from hydro and thermal power plants, and partly from the Krško nuclear power plant, which is co-owned by Croatian and Slovenian state-owned power companies.

Hrvatska elektroprivreda (HEP) is the national energy company charged with production, transmission and distribution of electricity.

In 2009, electricity consumption totaled 17.5 terawatt-hours, which is about 1% less than in 2008.[1]

Production

Energy production in Croatia

Total installed capacity of generating objects built in Croatia amounts to 3745 MW, 2079 MW of which is hydropower's share, and 1666 MW comes from thermal power plants. There are 25 hydroelectric power plants, most of which are located on the coast (including the single pumped storage hydroelectric plant, RHE Velebit), and 7 thermal power stations, 3 of which also generate heat for industry and heating in cities. Also, 338 MW is available from the co-owned Krško nuclear power plant, and 210 MW from the privately owned Plomin 2 thermal power plant.[2]

In 2009, domestic production amounted to 12015 GWh, which was 67.9% of total domestic demand. Remaining 32.1% was covered through trade. Total consumption equaled 17697 GWh, a 1% decrease from 2008.[3]

Transmission

Croatian transmission grid consists of lines on three different rated voltage levels, namely 400, 220 and 110 kV. Total length of high-voltage lines is 7,315 km (4,545.33 mi).

The grid was often the target of attacks during Croatian War of Independence, resulting in frequent black-outs during the period. Since then, the grid has been repaired, and reconnected to synchronous grid of Continental Europe synchronous zones 1 and 2, making it an important transit system again.[4]

Distribution

Under the 2004 Energy law, customers in Croatia are allowed to choose their preferred distributor of electricity. However, HEP Operator distribucijskog sustava or HEP-ODS (a Hrvatska elektroprivreda subsidiary) remains the largest distributor to both industry and households. Its distribution grid is 132,938 km (82,603.84 mi) long, with 26764 transformers installed, totaling 14170 MVA of power.

In 2009 there were 2310811 customers, 90.8% of which were households.[5]
