Jupiter Bach grew out of the 2017 merger between Jupiter Group and BACH Composite Industry – two world-leading wind specialists.

From our start as two small, independent manufacturing companies, Jupiter Bach has grown into the unified leader in nacelle and spinner covers. When we were founded, both businesses served a variety of industries. But as time passed, we learned that wind was where we could add most value and deliver a comparative advantage. Today we are 100% devoted to the wind turbine industry. Decades of experience with its demanding quality and documentation requirements, combined with our product development expertise, has made us the partner the world’s leading OEMs depend on.

90,000 m2 manufacturing capacity – and growing

As the demand for our products and services has increased, we have gradually expanded our global activities. Our first production sites were in Denmark. Today, we have 90,000 m2 of manufacturing capacity in six countries on three continents – each location with a dedicated engineering team. And with our ability to establish temporary, on-demand manufacturing sites for even greater scalability and flexibility, that number is always growing.
