ENERCON Achieves Milestone with First Kilowatt Hour Fed Into Grid from E-175 EP5 E2 Prototype

The prototype of the E-175 EP5 E2 was successfully commissioned.

(IN BRIEF) ENERCON has successfully commissioned the E-175 EP5 E2 prototype at the Wachendorf site in Lower Saxony, marking a key milestone in the turbine’s development. The E-175 EP5 E2, with a rated power of 7.0 MW and a rotor diameter of 175 meters, is one of the most powerful onshore turbines in Europe. The new external rotor design increases the generator’s power capabilities. With successful installation and commissioning, ENERCON is now preparing for the series production of the new turbine technology.

(PRESS RELEASE) AURICH, 16-May-2025 — /EuropaWire/ — A significant milestone has been achieved in the prototype programme for ENERCON’s E-175 EP5 E2, as the turbine at the Wachendorf site in Lower Saxony successfully fed its first kilowatt hour into the grid earlier this week. “This is fantastic news!” exclaimed Jann-Hendrik Wehmeyer, Project Manager for the Generator in the E2 programme at ENERCON R&D. “The entire prototype team has worked tirelessly to bring us to this important achievement.”

The E-175 EP5 E2 is the latest top-tier model in ENERCON’s portfolio. With a rated power of 7.0 MW and a rotor diameter of 175 meters, it stands as one of the largest, most powerful, and efficient onshore turbines currently available in the European market.

The increase in rated power compared to the previous E-175 EP5 model, which offered 6.0 MW, stems from the new external rotor design of the generator. This design enables a larger air gap diameter to handle higher torques and generate greater power. To facilitate efficient transportation of the larger components, the generator is delivered in two halves and assembled at the construction site during installation.

“We’ve now installed this new generator type for the second time, following the initial installation a few weeks ago at our test stand in Aurich. Everything went smoothly in Wachendorf as well,” Wehmeyer reports. “The installation and commissioning of the prototype progressed quickly, which gives us confidence as we prepare for the series production ramp-up of this new technology.”

The next steps at the Wachendorf site will involve further commissioning of the prototype. The team will gradually increase the turbine’s output to its nominal power, with additional tests and measurements planned to validate the new system design.
