Headquartered in Paris, France, TSG operates across 30 countries with over 7,000 employees and annual revenues of more than €1.4 billion. The company designs, builds and maintains critical energy infrastructure across Power (HV, MV & LV electrical), Charge, Solar, Battery Energy Storage Systems (BESS), Biofuels and Gas & Biogas. TSG’s multi-energy capabilities, deep technical expertise and extensive geographical coverage underpin longstanding relationships with a diverse base of leading energy infrastructure operators, and position the company to capture structural growth in electrification and the rising investment required in Europe’s critical energy infrastructure.
Acquisitions will remain an important part of TSG's growth strategy. TSG will continue to evaluate complementary acquisitions that broaden the range of technical services and energies it offers its customers and extend its geographic coverage, building on close to 50 acquisitions completed in under four years across 20 countries. The company has maintained strong momentum since the transaction was announced, with recent acquisitions including Powertek Utilities in the UK (electric grid connections and upgrades), TEPU Holding AG in Switzerland (electrical services with a focus on complex data centre infrastructure) and Processkontroll Green Technology in the Nordics (compressed and liquid gas infrastructure). TSG is actively evaluating, and in discussions with, a number of further acquisition opportunities across Europe, and expects to accelerate this programme under CapVest’s ownership.
As a leading private equity investor, CapVest is known for partnering with ambitious companies supplying essential goods and services and for transforming the size and scale of its portfolio companies through a combination of organic and acquisition-led growth. Members of the management team and HLD have reinvested alongside CapVest and retain significant minority stakes in TSG, underscoring their confidence in the company’s future trajectory.
Fred Raikes, Partner at CapVest, said: “We are delighted to complete this investment and begin our partnership with Jean-Marc Bianchi and his outstanding team. TSG occupies an important position in Europe’s energy infrastructure, serving customers across both traditional fuel and new energies, and we see a significant opportunity to accelerate its growth organically and through complementary acquisitions. We look forward to supporting the team as they build on their exceptional track record.”
Jean-Marc Bianchi, Chairman & CEO of TSG, said: “The completion of this transaction marks the beginning of an exciting new chapter for TSG. CapVest's philosophy of significant investment in people, innovation and capabilities, and its focus on both organic and acquisition-led growth, strongly reflects our own principles and ambitions. I would like to thank all of our employees, whose skill and commitment are the foundation of everything we have achieved, and HLD for their support throughout the first phase of our growth and transformation journey. We now look forward to pursuing the next chapter of that journey with CapVest’s full backing.”
Cédric Chateau, Partner and Chairman of the Investment Committee of HLD, said: “TSG has experienced an incredible acceleration over the past five years under our ownership alongside management, expanding rapidly across electric mobility, gas, solar and energy storage. The growth potential ahead is still significant and the company is now firmly established and ready to scale further. We are delighted to expand this journey alongside the management and CapVest.”
