November 2026 – Northern Germany, Tesar
A major wind energy project in Northern Germany is the latest destination for Tesar’s transformer technology, with the successful dispatch of a customised 16 MVA cast resin transformer designed to meet the demands of renewable energy infrastructure.
As Europe continues to expand its renewable energy capacity, the electrical infrastructure supporting wind generation must deliver reliability, efficiency, and resilience in increasingly demanding operating environments.
For R&S Group company Tesar, this latest project demonstrates the engineering expertise and manufacturing capabilities required to deliver high-capacity cast resin transformer solutions tailored to specific customer and application requirements.
High-Capacity Engineering for Demanding Conditions
With a rated power of 16 MVA, a 30/11 kV voltage ratio and a 36 kV insulation class, the transformer has been designed to meet the technical requirements of the wind farm installation.
Located in Northern Germany, the project also presents environmental considerations, with outdoor electrical equipment exposed to changing weather conditions throughout the year.
To meet these requirements, Tesar has equipped the transformer with a robust IP34-rated outdoor enclosure, protecting against solid-object and water ingress while allowing the equipment to operate outdoors
The result is a customised solution that combines substantial power capacity with the environmental protection required for its intended application
Customised Solutions, Built Around the Application
Every renewable energy project presents its own engineering challenges, from electrical specifications and installation conditions to operational requirements.
Tesar’s ability to develop application-specific cast resin transformers enables customers to address these challenges with solutions designed around their individual project needs.
The 16 MVA transformer supplied for Northern Germany reflects this approach, combining high-capacity transformer technology, specialised engineering, and a purpose-designed outdoor enclosure into a single solution.
Strengthening R&S Group’s Contribution to Renewable Energy
The successful delivery marks another project for Tesar in the renewable energy sector and reinforces the breadth of transformer expertise available across R&S Group.
With manufacturing capabilities spanning oil-filled distribution transformers, cast resin transformers, and power transformers rated up to 160 MVA / 220 kV, the Group supports customers across the energy value chain, from renewable generation and industrial applications to electricity distribution and transmission infrastructure.
As investment in renewable energy continues, projects such as this demonstrate the importance of specialised transformer engineering in delivering the electrical infrastructure needed for a more sustainable energy system.
Through Tesar and its wider portfolio of transformer technologies, R&S Group continues to support the development of reliable, resilient power infrastructure for Europe’s evolving energy landscape.
