Belgian Energy Island in North Sea Starts Taking Shape (Video)
; artificial energy island.Caissons are concrete building blocks that form the outline of the future island. In a later phase, the interior will be filled with sand to build high-voltage infrastructure that will connect new offshore wind farms.TM Edison is carrying out the work on behalf of grid operator Elia Transmission Belgium (Elia). In the coming decades, the energy island will become an essential part of Belgium’s electricity supply.The transport and installation of the caissons at sea is a technically complex operation that began on April 21, 2025. Each caisson weighs approximately
Cyprus: Subsea Power Cable Project to Move Forward
A project on a subsea power cable to link continental Europe to the East Mediterranean will materialize, Greek foreign minister said on Thursday after meeting his Israeli and Cypriot counterparts.Media reports earlier this week suggested that the project had stalled over territorial differences.Greek power grid operator IPTO ADMr.AT is building the Great Sea Interconnector (GSI) cable, which will link transmission networks of Europe to Cyprus. It will later stretch to Israel through the Mediterranean Sea.(Reuters)
UK Approves Five Subsea Power Cable Projects
for infrastructure at Ofgem said in a statement.Ofgem also approved Britain's first offshore hybrid assets (OHAs), which can directly feed energy generated by offshore wind farms into both British and European grids, and are both planned by National Grid.The LionLink project, co-owned by Dutch grid operator Tennet, will connect Dutch offshore wind farms to both the Dutch and the British grids and provide up to 1.8 GW of low-carbon electricity to each country.In the same way, the Nautilus project, co-owned with Belgian grid operator Elia, will connect Belgian offshore wind and provide up to 1.4 GW

Hollandse Kust (west) Alpha Offshore Substation Set for Wind Turbines Link-Up
(west) Alpha offshore substation is officially ready for commissioning after receiving grid readiness certificate three months ahead of schedule.This means that wind farm operator Ecowende can connect the wind turbines, which will be located about 50 kilometers off the coast of Egmond aan Zee, to grid operator TenneT's 'socket at sea’ as soon as they are built.Whereas completion was scheduled for the first quarter of 2024, TenneT received the grid readiness certificate from DNV before the holidays in 2023.This makes the grid connection of the 'socket at sea' to the national electricity
The Curious Case of the 1,200 MW Transmission Size “Limit” in New England
of 2,200 MW Was Recast to a 1,200 MW CeilingAs policy makers and energy developers look to develop and interconnect large offshore wind projects in the most economically efficient and least environmentally impactful way, an issue has developed. A relatively recent limit, set in place by the grid operator in New England in a planning process document, states that no single system loss of energy, or “contingency”, can be larger than 1,200 megawatts (MW). This 2016 addition to ISO New England’s (ISO-NE) Planning Procedure No. 5-6 is increasingly creating consternation among
France's RTE Taps Fugro for Geotechnical Survey for Offshore Wind Substations in Mediterranean Sea
French transmission grid operator Réseau de Transport d’Electricité (RTE) has awarded Fugro a contract to perform a geotechnical investigation for future offshore substations (OSS) at two floating wind farm sites in the Gulf of Lion in the Mediterranean Sea.Offshore Substations collect the electricity produced in wind turbines and convert it to a high voltage before being transferred onshore via export cables. Fugro’s Geo-data will provide insight into seabed conditions, to enable efficient OSS design and help derisk the project’s future developmental phases.Fugro on
Subsea Power Link Between Spain and France to Go Ahead Despite Cost Increase
Spain and 46% for France. The burden for Spain is slightly lower than what was agreed in 2017, according to a source at the Spanish regulator.Reuters reported earlier on Thursday that the two countries were close to an agreement over the distribution of costs for the project.Spanish power grid operator REE blamed the increase in costs on the "saturation of markets for the production of materials" and a shortage of companies with the technical capacity to build the cable. It did, however, see opportunities for greater profits."The expected profits of the project have also
First Sea Cable Installed for TenneT's West Alpha Offshore Substation
Jan de Nul Group and LS Cable & System have completed the installation of the first sea cable for West Alpha offshore wind substation for Dutch grid operator TenneT. The offshore installation contractors used the cable-laying vessel Connector and the remote-controlled cable-laying vehicle UTV1200 for the operation.Over sixty kilometers of cable were laid in the seabed between the Heemskerk beach on the Dutch coast and the jacket foundation of the transformer platform at sea.With over sixty kilometers of marine cable on board, the cable-laying vessel Connector from contractor Jan de
