Quality, sustainability, and safety are part of our DNA
Four independent certifications confirm WT Energiesysteme's commitment to quality, sustainability, the environment, and safety.
The development of modern energy infrastructure places high demands on planning, execution, and collaboration. Reliable processes, the highest quality standards, and responsible conduct are the foundations for sustainable project success.
We are therefore especially pleased that this commitment has once again been confirmed by independent bodies.
WT Energiesysteme GmbH has been successfully recertified in accordance with the international standards DIN EN ISO 9001 (quality management), DIN EN ISO 14001 (environmental management), and DIN EN ISO 45001 (occupational health and safety management) by TÜV SÜD.
In addition, we have been awarded the EcoZert 2026 by the Creditreform Group. This certificate confirms our commitment to sustainability in the areas of environmental, social, and corporate governance (ESG), as well as our economic stability.
For us, these accolades are far more than just formal documentation; they validate the high standards we apply to the execution of our projects every single day.
Ralph Nickstadt, CFO of WT Energiesysteme GmbH, states:
“As a corporate group, we support projects across the entire value chain of energy infrastructure. This requires reliable processes, the highest quality standards, and sustainable practices. These renewed certifications and the EcoZert confirm precisely this commitment. They also serve as an incentive for us to continuously refine our processes and remain a reliable partner to our clients in the future.”
We extend our thanks to all our colleagues who bring these standards to life every day. Their dedication makes the difference and forms the basis for safe, sustainable, and future-proof energy infrastructure.
