Dutch open largest offshore wind farm
13 May, 2017
One of the biggest offshore wind farms in the world has just started turning in the North Sea, off the coast of the Netherlands. Hidden over the horizon, the Gemini wind farm is set to produce about 2.6 TWh of electricity every year.
Situated 85 km north of the coast of Groningen, the Gemini wind farm is made up of 150 turbines spread out across 68 sq km. The spot was chosen because the wind speeds in the area are consistently high, averaging about 36 km/h. With a capacity of 600 MW, Gemini is the second largest offshore wind farm in the world, behind only the London Array.
The electricity generated by Gemini's turbines is collected into two nearby substations before being piped 110 km to the Eemshaven seaport. There, a land station will manage and maintain the entire facility, and the power is then fed into the country's grid. Over the course of a few decades, the Gemini wind farm will apparently supply up to 1.5 million residents with power, and reduce the amount of CO2 emissions by about 1.25 million tonnes every year. The project took more than two years to complete, with Van Oord and Siemens contracted to do the majority of construction.
