Your partner in underground gas storage

NAFTA is an international group with extensive experience in natural gas storage and underground facility development in Slovakia. It is also Slovakia’s leader in exploration of hydrocarbons. Across Europe, NAFTA actively operates gas storage facilities, explores of hydrocarbons and participates in renewable energy storage projects. NAFTA provides development, engineering and advisory services for facilities with overall storage capacity of approximately 64 TWh. In addition to Slovakia, NAFTA is present in the Czech Republic, Germany, Great Britain, Austria, and Ukraine.

It has been more than 50 years since we built our first underground gas storage facility. Years of experience in underground gas storage has enabled us to acquire extensive and valuable know-how in one of the technologically most complex fields. The quality of services and our individual approach has earned us the long-time trust of our clients and partners.

NAFTA’s Exploration and Operation Division has a central place in our history, as we were present at the birth of the oil and gas industry in the Austro-Hungarian Empire more than 110 years ago. We are also proud of our legacy of constructing and operating underground gas storage facilities in the Czech Republic and Slovakia. Our organization has gained extensive experience and built a strong team of professionals, including experts on geophysics, geology, drilling, reservoir and petroleum engineering.

In 2011, we developed the deepest part of the complex – UGS Gajary-Baden.

Since 1973, NAFTA has gained extensive experience in operating underground gas storages. In addition to running and developing its own storage facilities, NAFTA has been selected as the technical operator and the service provider for the underground gas storage facilities of our partners Pozagas and SPP Storage.

NAFTA applies its expertise in underground gas storage in a number of countries, taking advantage of the emerging technical and commercial synergies. In Germany it operates underground storage facilities Inzenham-West, Wolfersberg and Breitbrunn/Eggstätt, while in the United Kingdom NAFTA provides technical advisory services to Humbly Grove gas storage. NAFTA continues to seek new prospects for employing its know-how and is ready to expand its storage services further.

Breitbrunn/Eggstätt, Inzenham-West and Wolfersberg storage facilities are depleted gas fields and hold a total working gas capacity of 1,780 million cubic meters, or 20 TWh. All three facilities store H-gas and commercially fall under the market area Trading Hub Europe. Storage capacity at Inzenham-West is marketed by NAFTA Speicher Inzenham and at the remaining two storage facilities by our partner storage operators – Uniper Energy Storage and Bayernugs. Inzenham-West is connected to bayernets transport system. For more information visit our website: www.nafta-speicher.de

Today, NAFTA operates and develops technology and services for facilities with more than 64 TWh storage capacity in several European countries, contributing significantly toward secure natural gas supplies.

We allow our customers to assign their Gas Storage Agreement to a third party. The receiving party does become our customer, carrying all rights and obligations arising from the original gas storage agreement. The assignment can cover the entire contractual storage capacity or a part of it.
