Convert green energy reliably
transformers for wind, solar, water & bioenergy
Stable power grids despite fluctuating feed-in: The R&S Group supplies energy-efficient transformers for renewable energy producers. Developed for sustainable energy infrastructures – in use worldwide.
Renewable energy needs reliable technology
The greatest challenge of our era is developing a robust infrastructure for renewable energies – from wind farms to hydroelectric power plants to bioenergy centres. The following applies:
The greener the energy, the more complex the grid integration.
Whether it’s decentralised grid feed-in, grid control, or microgrids – we understand the challenges faced by plant operators, utilities, and project developers.
With customised transformer solutions and over 100,000 units installed worldwide, we are actively shaping the energy transition – for stable grids and a secure, green future.
Why R&S for Renewables?
Optimised for volatile feed-in
Our transformers are designed for fluctuating weather conditions and changing generation profiles – ideal for wind, solar, hydro & biomass.
Energy efficiency with amorphous or low-loss cores
Minimise transformer losses with highly efficient materials and designs – for maximum grid efficiency with minimal CO₂ emissions.
Total Cost of Ownership in focus
Robust construction, minimal maintenance and durable technology ensure low operating costs over the entire life cycle.
Ready for storage & smart grid
Durable designs, minimal maintenance requirements and low operating losses ensure low life cycle costs.
International expertise with local strength
Manufacturing & service by Rauscher & Stöcklin, ZREW, Tesar (IT/PL/Gulf) and Kyte Powertech – for fast implementation worldwide.
Increasing demand
The global growth of renewable energies is advancing quickly. Regulations like the Green Deal and Net Zero Goals are driving a huge demand for resilient infrastructure – R&S supplies the right transformers.
Changing weather patterns
Weather-based power generation can vary greatly. Our technology ensures stable voltage and frequency – regardless of sun, wind, or clouds.
Microgrids & Decentralization
Generation and consumption are becoming more closely connected. Microgrids are transforming grid architecture. Our transformers are designed for decentralised solutions and grid perturbations – including protection and control components.
Quality Built into Every Detail
“Quality is not a final check. It is built into every stage of the process.”
