In Asset Management

Windpark De Drentse Monden en Oostermoer (DMO) is one of the largest onshore wind farms in the Netherlands, comprising three sub-parks and 45 wind turbines with a combined capacity of 175.5 MW. The wind farm generates renewable electricity for around 225,000 households each year, making it a significant contributor to the energy and climate targets of the Netherlands.

The project grew out of local initiatives by farming businesses in the Drentse Veenkoloniën, who saw an opportunity to strengthen their operations through renewable energy generation. Coordinated by the national government, these plans were brought together into a single, integrated wind farm. More than a hundred agricultural businesses contributed to it, which means that the project is not only large in scale but also born from the collaboration of various parties within the region.

Our Contribution

Ventolines has been guiding the project since the very first development phase, supporting the initiators at every major step towards delivery and operation. Our role included permitting, engineering, contracting and construction management, working closely with both regional and national stakeholders.

During the development phase, among others we handled construction and water permits, business case calculations and SDE subsidy applications, as well as extensive wind measurement campaigns using masts and LiDAR. We were also responsible for electromagnetic compatibility (EMC) management, a particular local requirement due to a highly sensitive radio telescope situated in the vicinity of the wind farm.

In the current operational phase, we share responsibility for asset management. Ventolines handles the day-to-day technical management of Windpark Drentse Monden Oostermoer, covering performance monitoring, HSSE, maintenance and quality oversight, permitting, local site management and LOFAR coordination. Ventolines also takes care of commercial and financial management, contract and PPA management, invoice and risk control, reporting and stakeholder support.

Impact

The wind farm not only delivers large-scale renewable electricity, but also offers scope for further optimisation of the regional energy system. Two of the three sub-parks within DMO are exploring the development and contracting of large-scale battery storage systems, which will take their charge from the generated wind energy and function as supplements to the wind farms. By storing energy locally and delivering it to the grid more flexibly, output can be better aligned with demand and the existing local grid infrastructure can be used more efficiently.
