Reactive Power Compensation – MV Capacitor Banks for Renewables

RE-Tech supplies Circutor MV compensation solutions for wind and solar farms.

Renewable generation often creates reactive power imbalances that must be corrected to ensure grid stability and efficiency. RE-Tech offers medium-voltage capacitor banks that reliably manage reactive power while ensuring compliance with utility requirements.

In Cooperation with Circutor

RE-Tech represents Spanish manufacturer Circutor, a specialist in reactive power compensation and filtering. Circutor solutions are widely used across European renewable energy sites and meet strict Finnish grid codes.
