Operations management for your wind turbines

For us, operations management means: transparent reporting, ongoing yield optimization and condition-oriented maintenance:

Every minute, our control room monitors and evaluates the online energy data and the operating status of the plant. And it does this 24 hours a day, seven days a week - as if we were on site around the clock. We also pool expertise from other specialist departments to create the greatest possible synergies. We do all this with the aim of achieving maximum energy availability for your plants.

Our operations management is divided into four teams: Technical Operations Management Germany, Technical Operations Management International, Commercial Operations Management and Support. This ensures that we maintain a holistic but also focused view at the same time. In addition, we can set thematic priorities that are transparent and comprehensible for everyone.
