Power Transformers – Enabling Grid Connection for Renewable Energy

RE-Tech’s power transformers ensure reliable grid connection for solar and wind farms.

Renewable energy projects such as solar and wind farms require high-capacity transformers to step up voltage from medium to high levels. RE-Tech delivers custom-optimized power transformers that meet both technical and national grid requirements.

Designed for Renewables

Renewable generation has different load profiles compared to conventional sources. Our transformers are designed for:

  • Wind power fluctuations
  • Solar generation peaks
  • Grid voltage and power requirements
  • Nordic environmental conditions

We specialize in 20/110 kV and 33/110 kV connection points, where high performance and reliability are essential.

Sustainable and Grid-Compliant Solutions

RE-Tech’s transformers are fully compliant with Fingrid and DSO connection codes (VJV). Upon request, we offer units with biodegradable insulating oils. All solutions can be tailored to the site’s network profile and environmental conditions.
