TNL is a specialized provider of environmental planning, permitting, and construction services for complex infrastructure projects. Founded in 1994, the company supports challenging construction projects such as wind and solar farms, high- and extra-high-voltage power lines, and transportation infrastructure projects. TNL supports its clients throughout the entire project lifecycle: from preliminary environmental assessments through regulatory permitting processes to subsequent construction supervision and implementation. The group employs approximately 250 people across four locations and generated total revenue of approximately EUR 30 million in 2025.
Market characterized by structural growth
The investment follows DBAG’s strategy of making targeted investments in companies that operate in structurally attractive markets. The expansion of transport infrastructure, the energy transition and the expansion of the German transmission grids as part of the Network Development Plan (NDP) are driving a sustained high demand for qualified environmental planning services. This dynamic is also reflected in TNL’s development: the company’s core market has grown at an annualized double-digit percentage rate since 2020.
Tom Alzin, Spokesperson for the Executive Board of Deutsche Beteiligungs AG, says: “TNL is a true hidden champion in a non-cyclical growth market. The company provides indispensable planning services for projects that are absolutely essential to the success of the energy transition.”
