The 630-megawatt London Array wind farm, which currently holds the world record as the biggest wind farm ever made, may soon be dethroned by the very same company that made it, with Dong Energy, Denmark's largest energy company, planning an even more massive project - the 660-megawatt Walney Extension wind farm, according to Engadget.

When completed, the Walney Extension will be the world's biggest offshore wind farm. It is set to be installed in the Irish Sea, about 19 kilometers (about 12 miles) off the coast of Cumbria.

The Walney Extension is expected to be fully operational by 2018, providing about 5,089 megawatts of clean energy to the U.K. and German infrastructure, reports Maritime Executive.

Samuel Leupold, executive vice President at Dong Energy, is very optimistic about the project.

"Walney Extension will deliver clean electricity to more than 460,000 U.K. homes and I'm very pleased that we can now start construction of what will be the world's biggest offshore wind farm when completed. Building this offshore wind farm will bring us significantly closer to realizing our strategy of having 6.5GW of installed capacity online by 2020," he said.

Dong Energy is already among the companies at the forefront of clean energy. The company is currently constructing a 2,080-megawatt project in the U.K. and Germany. If Dong Energy is able to complete all of its projects, including the Walney Extension, it would provide enough power to correspond to the yearly power consumption of 12.5 million Europeans.
