What NAFTA does

NAFTA a.s. is a Slovak publicly held energy company founded in 1900 that operates as the 6th largest underground natural gas storage operator in Europe, managing approximately 64 TWh of total storage capacity across Slovakia, the Czech Republic, Germany, and the United Kingdom. Its core business centers on storing natural gas in depleted hydrocarbon reservoirs using porous geological structures, complemented by enhanced oil recovery techniques that extend reservoir life by 8-10 years and drilling and workover services executed to depths of 2,500m (drilling) and 4,000m (workover). The company's technology stack includes GC-IRMS gas analysis systems, optical gas imaging for leak detection, a DRILLMEC MR 4000 DB mobile drilling rig, and slickline services with operations up to 6km depth.

NAFTA generates revenue through a diversified mix of recurring subscription storage tariffs (Flexible, Seasonal, and Storage Capacity with Adjustable Compulsory Flows), usage-based injection/withdrawal rate charges, innovative financial products (Inverse Storage, Options on Storage Capacity, Framework Agreements), and professional services including drilling, workover, laboratory analysis, and diagnostics provided to external customers such as POZAGAS, SPPS, Innogy/RWE, VNG Gasspeicher, and Humbly Grove Energy. Pricing is regulated by Slovakia's Regulatory Office for Network Industries (URSO) for Slovak operations, while German operations run through wholly-owned subsidiary NAFTA Speicher GmbH. The go-to-market motion is enterprise B2B via formal tenders and contractual negotiations, with a customer portal and secondary capacity trading platform enabling ongoing account management.

The company is actively positioning for the energy transition through four hydrogen storage research projects (Underground Sun Storage, Henri, HyStorage, HyUsPRe), photovoltaic installations (a planned 1 MW plant at Ptrukša in 2026 alongside existing 41.18 kW capacity), and reservoir-to-storage conversions (25% of exhausted reservoirs converted to date). Exploration activities extend into Ukraine via joint ventures, while UK operations consist of technical-advisory services. The company holds ISO 9001, 14001, and 45001 certifications alongside sector-specific credentials (SCCP, IWCF) and operates with 463 employees as of December 31, 2025.
