Transformers for renewable energy applications

The global power sector is undergoing a rapid transition, driven by the accelerated deployment of renewable energy sources such as solar PV, onshore and offshore wind, and advanced energy storage systems. As renewable penetration increases, ensuring stable grid integration, reliable generation, and efficient transmission becomes essential. Transformers are a critical element in this process, adapting voltage levels and enabling safe, efficient, and uninterrupted power flow from generation assets to the grid.

TMC designs and manufactures a full range of dry-type transformers specifically engineered for renewable applications, combining high electrical performance, mechanical robustness, and compliance with the most demanding international standards.

Transformers for wind power (Onshore & Offshore)

TMC transformers are purpose‑built to operate in the harsh and dynamic environments typical of wind applications:

• Onshore Wind Turbines: compact step-up transformers designed for high mechanical withstand due to turbine-induced vibrations, load fluctuations, and grid disturbances. Optimized insulation systems ensure long operational life and elevated resistance to humidity, dust, and temperature variations.
• Offshore Wind: Specialized solutions for offshore platforms enhanced insulation systems, and protection levels suitable for marine environments (up to IP-class configurations).

Transformers for solar plants

TMC provides high‑efficiency dry-type cast resin or VPI transformers for photovoltaic inverter stations, engineered to comply with the latest ECO Design 548 regulation. Key features include:

• High-efficiency performance at fluctuating load profiles.
• Optimized thermal design for inverter‑close coupling installations.
• Compact footprint suitable for skid-mounted or containerized PV stations.
• Low losses for utility‑scale plants.

Transformers for Battery Energy Storage Systems (BESS)

TMC BESS transformers are engineered with:

• High short‑circuit withstand capability.
• Tailored designs for indoor or outdoor enclosed installations.
• Low noise and low partial discharge levels.
• Superior thermal behavior during fluctuating charge/discharge cycles.
• Compact solutions for integrated PCS + transformer skids.
