Gemini offshore wind farm official opening. A turning point in offshore wind

0

John Brace, Chairman of the Board of Directors of Gemini, officially opened the massive offshore wind farm on May, 8 in Eemshaven. With a 600 MW capacity, Gemini is one of the largest offshore wind farms in the world.

Gemini has been completed ahead of schedule, under budget and with an excellent safety record. Now fully operational, Gemini will produce 2.6 TWh of sustainable energy every year, reducing the Netherlands’ CO₂ emissions by 1.25 million tons. The wind farm is expected to contribute around 13% of the Netherlands’ total renewable energy supply, and approximately 25% of its wind power. Over the next fifteen years Gemini will meet the energy needs of 1.5 million consumers.

 

Gemini marks a turning point in the way we think about wind energy. The project’s magnitude has contributed to a rapid transformation of the sector. Today, the construction of offshore wind farms is more efficient and cost-effective than ever, and as a result there has been a significant reduction in the price of this potent renewable energy source.

Gemini is invisible from land, located 85 km off the coast of Groningen, in the North Sea. This location has some of the highest and most constant wind speeds in the North Sea, with an average wind speed of 36 km/h.

Gemini covers an area of 68 km2, and is comprised of 150 Siemens wind turbines with a capacity of 4 MW each, as well as two offshore high-voltage substations. Each substation is connected by to the land station in Eemshaven by a 110-km export cable. There, the electricity is converted to 380 kV and conveyed to the TenneT power station. Management and maintenance headquarters will be located in Eemshaven, and will create 75-100 permanent jobs.

Four companies combined forces to make Gemini possible: Northland Power (60% interest), Siemens (20%), Van Oord (10%) and HVC (10%). The construction of the wind park required an investment of 2.8 b€. The project was financed by 25 banks from Asia, Australia, Europe, and North America. To date, Gemini is the largest project financing for an offshore wind park.
