Sanda Mădălina Moise,
General Director of Depogaz Ploiești
Every winter, millions of Romanians turn on the heating in their homes, thousands of companies continue their operations, and the economy functions without most people ever considering the mechanisms that make it all possible. Few realize that before natural gas reaches power plants, factories, and households, it spends months within a complex underground infrastructure designed to respond to the most challenging periods of the year.

At the heart of this infrastructure is Depogaz, one of Romania’s most important strategic companies and, at the same time, one of the least visible to the general public. While energy producers and suppliers often occupy the spotlight, storage operators typically remain behind the scenes. Yet without their activity, a nation’s energy security would be impossible to guarantee.
In recent years, amid geopolitical shifts and profound changes in the European energy market, Depogaz’s role has become more important than ever. Energy crises, price volatility, and the need to reduce external dependencies have demonstrated that natural gas storage is one of the essential pillars of modern energy security.
As the specialized storage subsidiary of Romgaz, Depogaz manages Romania’s most significant underground natural gas storage infrastructure. Although much of its activity takes place far from public view, its impact is felt every day by both the economy and consumers.
The company operates five underground storage facilities located across different regions of the country, functioning as vast strategic energy reserves. During periods of lower consumption, natural gas is injected and stored underground. During the cold season, when demand rises significantly, these reserves are withdrawn and fed into the national gas transport system.
At first glance, the process may appear straightforward. In reality, however, it requires sophisticated technologies, meticulous planning, and a high level of technical expertise. Depogaz’s activity more closely resembles the management of a national strategic reserve than the operation of a conventional company.
The importance of this mission became particularly evident following the outbreak of the war in Ukraine. Europe quickly realized that energy security could no longer be treated solely as an economic issue. Energy had become a critical component of national security and political stability.
In this context, the European Union established clear targets regarding gas storage levels ahead of each winter season. Romania has consistently been among the countries that successfully met these objectives, and Depogaz’s contribution to this achievement has been decisive.
In recent years, Depogaz has entered a new phase of development. While the company’s primary focus in the past was managing existing infrastructure, it is now undertaking an extensive modernization and expansion program.
One of the most significant investment directions concerns the development of the Bilciurești storage facility, with European co-financing. As Romania’s largest natural gas storage facility and one of the most important in this part of Europe. The projects currently underway aim to increase withdrawal capacity and enhance operational flexibility—essential elements in an energy environment characterized by rapid change and constant challenges.
At the same time, the company is investing heavily in digitalization and automation. Advanced technologies enable continuous monitoring of operations, process optimization, and enhanced safety standards. In a sector where reliability is paramount, such investments are essential to maintaining high performance.
Another major challenge lies in adapting to the evolving trends of the energy transition. Although Europe is pursuing emissions reductions and expanding renewable energy sources, natural gas is expected to remain a significant component of the European energy mix for a considerable period.
Moreover, Depogaz’s extensive experience in managing complex underground facilities may prove to be a valuable advantage in the future development of the hydrogen economy and emerging energy storage technologies.
Beyond the technical and economic dimensions, the company’s activity also carries a profoundly human component. Behind every installation, every well, and every monitoring system stand professionals working to ensure that energy is available precisely when it is needed.
This responsibility demands expertise, professionalism, and the ability to manage complex situations in an industry where mistakes are simply not an option. For this reason, the company’s organizational culture is built around the principles of safety, responsibility, and performance.
Today, Depogaz represents one of the most important components of Romania’s energy infrastructure. Even though its work is not always visible to the public, its impact on the economy and on national energy security is both profound and constant.
The company’s story is, in essence, the story of an infrastructure without which the modern economy could not function. It is a story of responsibility, preparedness, and continuous readiness for future challenges. In a Europe seeking solutions to strengthen energy security, Depogaz stands as one of the pillars supporting Romania’s stability while contributing to the resilience of the wider region’s energy system.
