Dutch-German transmission system operator TenneT is to build a pilot artificial island in the North Sea as part of its plans to develop a “North Sea Wind Power Hub”, Recharge has learned.

The hub would be a large manmade island that would host a converter station and potentially link multiple offshore wind farms to multiple countries, and could act as an O&M base and even include battery storage, green-hydrogen production or a solar farm.

“This summer we should get to the stage where we can proceed with building a test site over the next three to five years,” Tim Meyerjurgens, TenneT’s chief operating officer, told Recharge on the sidelines of the Hamburg Offshore Wind event.
