TenneT is planning to invest an additional €215m in grid capacity to connect 2GW of wind and solar energy in the north Netherlands.
Two new 380 kV/110kV high voltage substations will be constructed in the provinces of Groningen and Drenthe.
The projects are expected to be completed around 2025, TenneT said.
In addition, the company wants to realise extra capacity at the existing 110kV high voltage substations in Bargermeer, Coevorden, Emmen Weerdinge, Hardenberg, Klazienaveen, Musselkanaal Zandberg, Ommen Dante, Stadskanaal and Veenoord.
One gigawatt corresponds to the capacity of around 3.5 million solar panels or around 200 wind turbines, TenneT said.
TenneT chief operating officer Ben Voorhorst said: “We want to honour as many transmission requests as possible for solar parks and wind farms.
“In view of the requests for connecting renewable projects, we will also look closely at where our sustainable investments are most needed and most efficient.
“The better capacity expansions of electricity grids are fully utilised, the better consumers’ money will be spent.
“In total we now have projects in the north worth more than €1bn. This €215m will come on top of that.”
