What Podzemno skladiste plina d.o.o. does

Podzemno skladište plina d.o.o. (PSP d.o.o.) is the sole operator of Croatia's underground natural gas storage system, a regulated monopoly under Croatian law and oversight of HERA (Croatian Energy Regulatory Agency). The company was founded in 1987 with the commissioning of its flagship PSP Okoli facility near Velika Ludina in Sisačko-moslavačka County. PSP Okoli uses porous geological formations to store natural gas at operating pressures of 25–45 bar, providing a maximum working volume of 438 million m³, daily withdrawal capacity of 5.76 million m³/day, and injection capacity of 4.32 million m³/day. The facility is monitored through annual HD well-integrity measurements and operates 24/7 from a security control centre, and it notably survived the December 2020 Petrinja earthquake without damage. A second facility, PSP Grubišno Polje in Bjelovarsko-bilogorska County, is under development as a strategic investment of the Republic of Croatia, with Phase 1 (gas preparation station and connection pipelines to Plinacro's Virovitica–Kutina transmission line, ~€33M) officially opened in January 2024 and total project investment estimated at ~€70M.

PSP serves only "energy entities" holding legal access rights under the Croatian Gas Market Act — gas traders, suppliers, distributors, and large industrial consumers — through a portfolio of four regulated service tiers: the Standard Storage Capacity Package (SBU), Individual Firm Services, Individual Interruptible Services, and Non-Standard Services. Capacity is allocated primarily through annual auctions on the primary market with secondary-market trading available, and tariffs are set and approved by HERA. Customer acquisition is not outbound-driven; demand is governed by the regulatory framework. PSP's GTM is sales-led but institutionally focused: a small commercial affairs department ([email protected]) handles reservations, contracting, and nominations, while communication is largely through the corporate website, regulatory publications in Narodne novine, and a dedicated PR/information officer.

The business is operated with a very lean team of 7 employees organized into two operational sectors (Technological Management under Laslo Farkaš Višontai and Business Functions under Renata Novosel-Belavić), reporting to Director Vlado Vlašić and a governance structure that includes a Supervisory Board, Audit Committee, and Management Board. Revenue is not publicly disclosed. Marketing activity is minimal, reflecting PSP's status as a regulated monopoly where customer relationships are determined by law rather than competitive positioning, and where competitive advantage derives from the legally enshrined sole-operator designation, irreplaceable geological assets, and integration into the national gas transmission network.

Revenue model

1. Gas Storage Capacity Services (SBU): PSP generates revenue primarily through the provision of standard storage capacity packages (standardni paket skladišnog kapaciteta), individual firm (stalne) services, and interruptible (prekidive) services. Storage capacity is allocated via auctions on the primary market and can be traded on the secondary market. The company operates under a regulated tariff framework overseen by HERA (Croatian Energy Regulatory Agency).
2. Non-Standard Services: Additional revenue is generated from non-standard services (nestandardne usluge) provided to storage system users beyond the standard capacity packages.

Direct peers

• MOL Hungarian Oil and Gas Plc: MOL Group operates multiple underground gas storage sites in Hungary (e.g., Kardoskút, Hajdúszoboszló) alongside its broader oil and gas business. Comparable to PSP as a regional CEE operator with depleted-reservoir storage assets serving regulated domestic markets.
• NAFTA a.s. Slovak operator of underground gas storage at Gajary-Báden and other depleted-reservoir sites. Comparable to PSP as a CEE national-scale UGS operator using similar geology and serving a similarly structured regulated market.
• Bulgartransgaz EAD: Bulgarian gas transmission system operator that owns and operates the Chiren underground gas storage facility. Functionally analogous to PSP as a national-level regulated operator combining TSO and UGS roles in a Southeast European market.
• VNG AG (Verbundnetz Gas): German gas company headquartered in Leipzig with significant underground gas storage operations across Germany. Comparable to PSP as a European underground storage operator, although at materially larger scale and operating in a more deregulated market structure.
• Gas Connect Austria GmbH: Operates Austrian UGS facilities including the Haidach storage complex, one of Central Europe's largest depleted-reservoir UGS sites. Comparable to PSP as a mid-sized regional underground storage operator with adjacent pipeline/transmission operations.

Broad incumbents

• Storengy: ENGIE subsidiary and one of Europe's largest underground gas storage operators, with extensive depleted-reservoir and salt-cavern capacity across France, Germany and the UK. Comparable to PSP in core storage operations, but significantly larger and operating across multiple jurisdictions.
• SNAM S.p.A. Major Italian gas infrastructure company operating multiple UGS sites (e.g., Fiume Treste, Sabbioncello) as part of a broader regulated transmission and storage portfolio. Comparable to PSP in storage operations, though much larger and geographically broader.

Others

• Plinacro d.o.o. Croatian gas transmission system operator and PSP's direct integration partner for both PSP Okoli and the new PSP Grubišno Polje project (connection to the Virovitica–Kutina main pipeline). Comparable as a regulated Croatian gas infrastructure operator, focused on transmission rather than storage.

Regional players

• Eustream a.s. Slovak gas transmission system operator with cross-border pipeline and storage-related operations in Central Europe. Comparable to PSP as a regional CEE infrastructure operator, though primarily a transmission business without dedicated national-scale UGS.
