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.
- Designed for renewable energy profiles
- Utility-approved solutions
- Fast delivery and RE-Tech’s technical support
Deliveries and References
Between 2022–2025, RE-Tech has delivered 10 MV compensation banks to various wind farms in Finland. Clients include developers and owners, with complete technical support and project-specific sizing included in every delivery.
When is Compensation Needed?
