What Depomures does

Depomures S.A. is a Romanian joint-stock company founded in 2002 that operates the Târgu-Mureș underground natural gas storage facility, the first and only privately operated underground gas storage site in Romania and the country's second-largest storage operator overall. The company operates under a Romanian state concession for storage activity and an ANRE (National Energy Regulatory Authority) license, with all tariffs regulated by ANRE. Its shareholder structure comprises ENGIE Group (formerly Gaz de France) with 59% majority ownership and Romgaz with 40%, anchoring the asset within two of the largest players in the Romanian and European gas value chain.

The facility currently provides an active storage capacity of approximately 300 million cubic meters per cycle, supplied through 18 production/injection wells and associated surface infrastructure including a treatment installation and pipeline interconnections to the national transmission system. Depomures generates revenue through three regulated service lines: capacity reservation (booking of storage capacity), injection (gas injection services), and extraction (gas withdrawal services), and claims to offer the lowest storage tariffs among Romanian operators. Storage capacity is allocated by priority, with first demand reserved for licensed gas suppliers covering mandatory stocks, followed by direct eligible clients and heat producers, creating a B2B-only customer base dominated by licensed suppliers and industrial offtakers.

Depomures has secured Project of Common Interest (PCI) status under EU Regulation 347/2013 for its expansion, and in 2024 signed a Connecting Europe Facility (CEF) Energy grant contract for approximately €12.77 million in EU co-financing. The associated project (PCI 6.20.4) covers construction of a new compression station and expansion of active storage capacity toward 400 Mm³ per cycle, with construction works launched in November 2024. This positions Depomures as a strategically relevant asset in EU efforts to strengthen regional gas storage security, particularly in the context of reduced dependency on non-EU gas supplies.

Revenue model

1. Underground gas storage services: Core revenue from three regulated service lines: (1) capacity reservation, (2) natural gas injection into the Târgu-Mureş underground storage facility, and (3) natural gas extraction (delivery to the National Transport System). Pricing follows ANRE-approved storage tariffs published per cycle (e.g., 2024/2025, 2025/2026, 2026/2027). DEPOMUREŞ states it offers the lowest storage tariff in Romania.
2. Storage access / capacity allocation fees: Revenue from selling regulated access to the storage facility via annual cycles, with priority allocation to licensed gas suppliers and direct-eligible clients (PET) up to mandatory minimum stocks, then on a first-come, first-served basis.
3. EU CEF Energy co-financing grant: Non-recurrent capital support of €12.77 million from the EU Connecting Europe Facility (CEF) Energy programme (contract signed 26 March 2024) for Phase 1 of PCI project 6.20.4 — building DEPOMUREŞ's own compression station.
