For the Vattenfall solar park in Almere, Protrafo supplied and delivered eight compact outdoor transformer units for direct grid connection at 20 kV. Each unit is rated at 3.15 MVA, enabling stable and efficient export of renewable energy from a 45 MW utility-scale PV installation to the local distribution network.
The solution was selected to match the project’s requirements for reliability, outdoor installation, and a compact site layout. By combining proven transformer technology with a practical footprint, the installation supports long-term performance under varying load profiles typical for solar generation.
With clear documentation, project coordination and on-time delivery, Protrafo ensured a smooth implementation aligned with the overall construction schedule. This project demonstrates our ability to support renewable infrastructure across Europe with dependable transformer supply and execution.
Connecting a solar park directly to the medium-voltage grid requires more than selecting a transformer, it requires the right configuration, documentation, and coordination to meet grid standards and project timelines. For this 45 MW project in Almere, Protrafo delivered a multi-unit approach with eight compact outdoor transformers, each rated 3.15 MVA at 20 kV, supporting efficient distribution and stable export. We aligned the technical scope with the site layout and installation planning, ensuring the units were delivered ready for integration and commissioning preparation. This structured approach reduces project risk and helps keep renewable grid-connection projects predictable and on schedule.
