Plinacro Ltd.

What Plinacro Ltd. does

Plinacro d.o.o. is the state-owned operator of Croatia's natural gas transmission system, established on January 19, 2001 and held 100% by the Government of the Republic of Croatia since March 2002. The company manages over 2,500 km of high-pressure pipelines, compressor stations, measuring-reducing stations (MRS), and cross-border interconnection points with Hungary, Slovenia, and Bosnia and Herzegovina, as well as the LNG terminal on Krk Island. It is the sole certified natural gas transmission system operator (TSO) in Croatia, regulated by HERA (Croatian Energy Regulatory Agency), and operates a 24/7 National Dispatch Center with SCADA, GIS, and SIMONE pipeline simulation systems for real-time network monitoring and control.

The company's customer base comprises distribution system operators, industrial customers, energy suppliers and balance group leaders, and neighboring TSOs requiring cross-border capacity. Plinacro monetizes its infrastructure through regulated tariff-based revenue, including capacity reservation fees and usage-based charges for natural gas transport, plus ancillary services such as telecommunications capacity leasing (2 Mbit/s to 2.5 Gbit/s) via its optical fiber network. The company has expanded its scope through its wholly-owned subsidiary Podzemno skladište plina d.o.o. (underground gas storage at Okoli) acquired in 2009, and its joint venture LNG Hrvatska d.o.o. with HEP for the Krk LNG terminal.

Plinacro is undergoing a significant capacity expansion, with plans to increase throughput from approximately 5 billion to over 10 billion cubic meters annually, supported by 443 million EUR of investment in the second cycle (2007-2011) and additional EU CEF and NPOO grant funding. Strategic partnerships with FGSZ (Hungary), Plinovodi (Slovenia), BH-Gas, TAP, and other regional TSOs position the company as a key node in Central European gas transit, with growing integration into EU energy market infrastructure frameworks.
