The Dutch-German transmission system operator (TSO) TenneT plans to invest a further €215m to connect two GW of green electricity from solar and wind farms in the north of the Netherlands to the grid. The infrastructural measures include the construction of two new 380/110kV high-voltage substations in the provinces of Groningen and Drenthe. In addition, the TSCNET shareholder intends to provide extra capacity at nine existing 110kV substations in the northern Netherlands.
One GW corresponds roughly to the output of 3.5 million solar modules or 200 wind turbines. The additional capacity planned by the TSO is therefore considerable, but according to Ben Voorhorst, COO of the TSO, as many solar and wind farm transmission requests as possible should be complied with. Already now TenneT operates projects in the northern Netherlands with a volume of more than €1bn. This level of investment is now being further increased, with the TSO focusing strongly on the sustainability and efficiency of the investments. “The better the capacity expansions of electricity grids are actually utilised, the better the consumer’s money is spent,” explains Voorhorst.
