Headquartered in Paris, France, TSG is a European leader in technical services for the energy industry with a pan-European footprint in over 30 countries and employing over 7,000 people. Originally focused on fuel station and private fleet energy infrastructure and systems, since HLD’s acquisition of the company in 2020 TSG has undergone significant transformation as a primary enabler of the energy transition, offering a diverse range of multi-energy technical services across Power (HV & LV electrical), Charge, Solar, Battery Energy Storage Systems (BESS), Biofuels and Gas & Biogas. Under HLD and management's leadership, annual revenues have grown to more than €1.4 billion with new energies accounting for approximately half of the revenue.
TSG’s current activities are focused on design, engineering and build, testing, equipment supply, maintenance and project management. As a result of these multi-energy capabilities, deep technical experience, and geographical coverage spanning 30 countries, TSG has established longstanding and trusted relationships with a diverse base of leading energy infrastructure operators, with many of these client relationships spanning several decades. TSG has achieved strong growth in recent years driven by positive medium- and long-term secular trends including the growing need for investment in critical energy infrastructure and the transition towards more sustainable multi-energy solutions.
