Description:

The Rentel export is the 220 kV HVAC submarine export connection that carries electricity from the Rentel offshore transformer / offshore high-voltage station (OHVS) to the onshore transmission grid at the Stevin substation (Zeebrugge). It serves the 309 MW Rentel offshore wind farm (42 × Siemens 7.35 MW turbines) and...
