What I have built


Throughout my career, I have worked on both onshore and offshore wind farms, as well as mobile substations. As lead engineer, I managed the complete high voltage grid connection design, construction and commissioning of two major offshore wind farms, Gemini and Norther. Both wind farms have a combined installed power of 970.000 Watt.
For a period of 25 years, these wind farms will provide green energy to over 1 million families.

Norther Offshore Wind Farm


Norther is an offshore wind farm with a maximum capacity of 370 MW. Upon completion, it will be the largest offshore wind farm in Belgium. Each year, it will generate around 1,394 GWh of sustainable energy, equal to the energy use of almost 400,000 families.

Gemini Offshore Wind Farm

The Netherlands

The 600 MW Gemini offshore wind farm consists of two offshore substations and one onshore substation. With two export cables of about 100 km, the Gemini high voltage grid connection pushed the boundaries of what is considered technically feasible with AC technology.

Techno-Economic Analysis of HVAC, HVDC and OFAC Offshore Wind Power Connections.

Jun, 2019 Stephen Hardy, Kristof van Brusselen, Stijn Hendrix (CG, Belgium), Dirk Van Hertem, Hakan Ergun (KU Leuven, Belgium)

Published and presented at the PowerTech 2019, Milan, Italy.

This work performs an economic analysis of High Voltage Alternating Current (HVAC) and High Voltage Direct Current (HVDC) transmission options for Offshore Wind Power Plants (OWPPs). The primary objective is to produce a range for each technology under which it is the most economic option. The economic model developed accounts for system losses and reliability. HVAC technological variations included are the use of a mid point compensation platform and Optimal Frequency AC (OFAC).

Optimal Design of the Mvar Controller of Far Shore HVAC Grid Connections

Oct, 2015 Tom Van Acker, Barry Rawn, Dirk Van Hertem (KU Leuven, Belgium), Stijn Hendrix, Etienne Lemaire (CG, Belgium)

Published and presented at the 14th Wind Integration Workshop in Brussels, Belgium.

This paper discusses the proposed design of a reactive power controller of a far shore HVAC grid connection under construction. The controller helps to reduce the negative effects associated with the increased capacitive charging current linked to the increasing HVAC cable lengths. Optimal usage of the reactive power capabilities of the both the Wind Turbine Generators (WTG) and the available onshore reactive compensation can lead to significant reduction of the active power losses resulting in financial gains.
