TenneT

TenneT was identified as the transmission system operator (TSO) responsible for the grid connection interface for the Eneco Luchterduinen offshore wind farm. Under the arrangement described, TenneT was to connect the wind farm’s electricity export from the beach landing onward to the switching and high-voltage station in Sassenheim, enabling power generated offshore to be fed into the Dutch onshore transmission network. The scope referenced related specifically to the onshore grid connection step at the TenneT substation and switching infrastructure, i.e., the point where the project’s export system is integrated into the wider high-voltage grid. This role sat alongside other connection works described for the project (including the installation of the underground cable route from the beach toward the high-voltage station), and reflects TenneT’s function as the grid operator providing the necessary connection, acceptance, and integration into its onshore assets. This grid connection responsibility supported the overall delivery of the 129 MW wind farm developed by Eneco and Mitsubishi Corporation, ensuring the project’s export system could be connected to the national grid at Sassenheim as part of the construction and commissioning pathway to operations.
