Cables
Two types of cables bring the produced energy in the Gemini Wind Park to the land: export cables and infield cables. The export cables, capable of carrying 220,000 volts, connect the park from the OHVSs to the land. They have a diameter of 30 cm and weigh 90 to 140 kg per metre. They are encased in order to protect it from external influences. The infield cables connect each wind turbine to one of the OHVSs and vary depending on the location of a wind turbine in the park. The more energy the cable must transport, the larger their dimensions.

A three-stage journey
The cable-laying process was divided into three main stages. First, laying the shallow water cable was performed between the Eemshaven seaport and the North Sea. Here, a great deal of focus was concentrated on laying the cables in a highly sensitive and unique area: the Wadden Sea (a UNESCO World Heritage Site). The tides make this a very dynamic area, so the cables had to be laid deep enough.

How the electricity travels
The electricity that is generated in the Gemini Wind Park has a long way to travel and goes through different processes along the way. The turbine generates electricity at 690 volts. The transformer in the turbine converts it to 33 kilovolts on the spot. Then there are seven to eight windmills in a loop with each other: the combined electricity goes to the OHVS, where the transformer converts it to 220 kilovolts. Then the electricity travels along the 85-kilometre cable that comes ashore in Eemshaven. There, we have a land station full of transformers, where the electricity is converted to 380 kilovolts so that it can be transported over longer distances.
And a few kilometres further on, Gemini has reserved a connection point with Tennet, the grid operator. After which it enters the homes – in reverse order– as 230 volts.
Spools and condensers are used to minimise electricity loss during transport. Gemini uses smart techniques to get the 600 megawatts that are generated in the wind park onto the grid. That has to be built up gradually. For delivery reliability, it helps that Gemini Wind Park has configured a number of facilities in duplicate: two OHVSs, each with two 180-megawatt transformers and two export cables.
