GMT Celebrates 30 Years: French Innovation Driving International Growth

This year, GMT celebrates its 30th anniversary. Since the company was founded in 1996 in the South of France, we have continuously evolved to support energy-sector stakeholders with solutions that are increasingly high-performing, innovative and resp

GMT's beginnings
The story began in 1996 with a product range focused on spill containment systems with removable side wall panels. At the time, GMT distributed its products exclusively on the French market.
Our drive to innovate and provide practical solutions to our customers' challenges soon led us to design our own solutions and invest in research and development.

International expansion: a new chapter
In 2008, GMT reached a major milestone with the creation of Akhelec Spain. This new operation marked the beginning of our international expansion and reflected our ambition to support energy-sector stakeholders beyond France's borders.
This international opening became a genuine growth accelerator. It encouraged knowledge-sharing, strengthened our capacity for innovation, and enabled us to meet the needs of increasingly diverse markets.
This strategy has fully delivered on its promise: in 2026, for the first time, international markets became GMT's largest market.

Innovation at the heart of our growth
The year 2009 marked another milestone with the launch of our fire-extinguishing cover, a solution that now protects more than 2,000 transformer containment pits. That same year, our organization obtained ISO 9001 certification, confirming our commitment to quality.
In 2010, two major innovations expanded our product range:
• BAFx modular fire-resistant containment systems for power and traction transformers;
• HYDROBLOC, a jointly owned patent with ENEDIS for a prefabricated solution designed to manage potentially oil-contaminated rainwater.
In 2011, GMT also developed temporary storage solutions.
In 2015, a new jointly owned patent with RTE led to the creation of HOLYBAG, designed for the on-site recovery and treatment of identified oil leaks.

A company that continues to grow and evolve
From 2017 onward, GMT entered a new phase of development.
The company developed and protected its own oily-water filtration systems under the FILTRELEC range. Today, more than 5,000 units are manufactured each year at our workshops in Avignon before being shipped across Europe, Asia, Oceania and the Americas.
That year also marked the launch of our business dedicated to renewable energy, reflecting our commitment to supporting the energy sector's ongoing transformation.
At the same time, GMT continued to strengthen its organization. Our teams grew, our expertise expanded, and quality, safety and performance became central to the way we operate. These efforts were recognized in 2018 when we achieved our first MASE (equivalent to ISO 45001) certification.

A responsible commitment
Because our responsibility goes beyond the performance of our solutions, in 2023 we launched a Corporate Social Responsibility (CSR) initiative and appointed a dedicated CSR representative to structure and coordinate our actions.
This approach reflects our commitment to long-term growth based on respect for people, the environment and the principles of ISO 26001.

A collective journey
For 30 years, GMT has built its story through the commitment of its employees, the trust of its customers, and the support of its partners.
Every innovation, every new market and every project delivered in France or internationally is the result of a collective effort and a shared ambition: to provide reliable, innovative and sustainable solutions to energy-sector stakeholders.
While our business has expanded significantly around the world, our roots remain firmly local. From Avignon, we continue to design, develop and manufacture our solutions, with the ambition of showcasing our expertise internationally while remaining a committed contributor to our local community.
For 30 years, GMT has grown, innovated and supported energy-sector stakeholders in their projects. We will continue moving forward with the same ambition: to contribute to a sustainable future by designing innovative solutions that improve the safety of electrical substations, protecting both people and the environment.
