Organization
TenneT is Europe’s first cross-border grid operator for electricity. With approximately 22,000 kilometers of (extra) high-voltage lines and 41 million end-users in the Netherlands and Germany, we rank among the top five grid operators in Europe. Our focus is to develop a North-West European energy market, to integrate renewable energy, and to optimize our safety performance. Safety & Security is a core value of TenneT. We set high standards for our employees as well as our contractors. Taking power further.
TenneT is currently replacing its EMS/SCADA system as part of a program to achieve a ‘Control Room of the Future’. The EMS/SCADA system is the main application for steering and controlling the high-voltage grid. Part of this program is the realization of an integration platform which is situated between the EMS/SCADA system and the IT landscape.
For the IT-OT integration team we are looking for a:
