Engineering, Grid Connection & Technical Support Services
Marine Techno Services provides engineering, grid connection application, and technical support services for solar power plants and grid-scale battery energy storage systems (BESS).
In the field of solar power generation, our representative has more than 10 years of experience in system design and utility grid application procedures, having handled a wide range of projects and developed strong practical expertise and flexible problem-solving capabilities.
For grid-scale battery systems, we began supporting grid connection study applications in December 2022, and have since provided technical consultations and application support for numerous projects nationwide.
In June 2025, the renewable energy business previously operated by our representative as an individual practice was formally transferred to and launched under Marine Techno Services.
Based on these accumulated experiences, we are now strengthening our corporate structure and delivering more stable and advanced technical services as a company.
Please feel free to contact us for further information.
