RWE is developing the Oostpolder wind farm in the Oostpolder area in Groningen through collaboration with local landowners within the Waddenwind collective. This wind farm consists of 21 wind turbines, 8 of which are to be constructed by RWE.

A Lagerweij climbing crane turbine – like the one at the Oostpolderdijk wind farm – is to be used for this wind farm. This turbine has a climbing construction for a crane on the turbine, allowing the crane to have a small footprint. Work on the wind farm is scheduled to start in 2020 and it is expected to be put into operation in 2021. The completed wind farm will cover the annual consumption of more than 100,000 households.
