Making the energy transition happen

The energy transition is transforming the electricity system. The continued expansion of renewable energy, rising connection volumes and growing transmission needs are creating new requirements for grids and infrastructure. For TransnetBW, this means ensuring the reliable operation of the electricity system while continuing to expand the grid infrastructure needed for the future.

At the same time, one thing is clear: the transformation of the energy system is not automatically sustainable. It has impacts on the environment, requires resources and relies on public acceptance. Our ambition is to consider these ecological, social and economic aspects responsibly in our decisions.

In 2025, we continued to advance key sustainability topics. This included further implementing our Climate Action Plan, expanding our environmental management system with ISO 50001 energy management certification and strengthening the sustainable and resilient development of our infrastructure. We are also increasingly integrating sustainability considerations across the entire lifecycle of our assets.

With the 2025 reporting year, we are aligning our sustainability reporting for the first time with the voluntary VSME standard. The report provides transparent insight into our sustainability performance and includes additional key figures, disclosures and challenges beyond the standard requirements.

We invite you to explore our Sustainability Report 2025 and learn more about our sustainability activities and progress.
