In 2010, still operating under the name SENKO, we completed our first major EPC project – a milestone for our company and a technological catalyst for the region.
The aim was to connect a wind farm with ten MM92 wind turbines (2 MW, Repower) to the 110 kV high-voltage grid of a Polish grid operator, including planning, delivery and commissioning.
We focus on consistent in-house development, close coordination with partners and bold technology choices:
Each wind turbine was equipped with a compact transformer station that transformed the generator voltage from 690 V to 30 kV. We designed our own product specifically tailored to the requirements of the project.
Together with our enclosure suppliers, we developed a new transformer station concept that combined 36 kV medium-voltage distribution and outputs of up to 3,150 kVA in a compact design – economical and efficient.
The park’s internal medium-voltage lines were brought together in the newly constructed 110/30 kV substation and raised to high voltage level (110 kV) – for a secure grid feed.
One technological highlight was the first-ever implementation of GE’s (formerly Areva) HYpact hybrid switchgear system in Poland. This compact, low-maintenance and powerful solution proved highly impressive – and was successfully launched on the market thanks to our project.
The project was implemented in its entirety – from planning and delivery to construction and commissioning. With the successful installation of the first HYpact system in Poland, we set a technological milestone. The central 20 MVA substation was completed on schedule and the ten individually developed transformer stations were delivered to fit perfectly. Since commissioning, the entire plant has been running smoothly – for over 13 years. The international customer from Portugal was highly satisfied with the result. In addition, the project had a lasting effect on the market: other network operators in Poland adopted the HYpact technology, confirming the innovative impetus we provided with this project.
With this first EPC project in Poland, we have demonstrated our expertise as a reliable partner for complex energy infrastructure projects. It was a milestone for us – technically, strategically and operationally. Its successful implementation underscores our ability to make innovative solutions marketable, manage processes efficiently and secure projects sustainably.
