A colossus of 260 meters with blades 107 meters long: the new Haliade-X wind turbine, a new company of General Electric, will be developed over the next three years.

Offshore wind has taught us to dream big. Over the past decade, turbines have tripled their power, cut their foundations, tested advanced materials, and reached record highs.

The last wind giant to reach the sea is the 9 MW mega turbine created by MHI Vestas Offshore Wind, developed by the union of Danish companies Vestas and Japanese Mitsubishi Heavy Industries.

As a prototype, this colossal wind turbine has successfully passed all tests: in January 2017, thanks to its 80-meter-long blades, it operated for 24 consecutive hours generating 216 MWh.

But it’s hard for a growing industry to keep pace. And breaking records for size or power has almost become an industrial sport. The test is General Electric (GE) Haliade-X’s latest development-ready turbine, a new 12 MW offshore mega turbine. The American multinational will join the project, which will last 2 to 3 years, contributing some 400 million dollars. The goal is to create a wind turbine 260 meters high with blades 107 meters long. Each unit alone must be able to meet the electrical needs of 5,000 average households.

We want to be leaders in the technologies that drive the global energy transition“- said John Flannery, president and chief executive officer of the American company in a press release -“and offshore wind power is one such technology and we will devote all of GE’s resources to making the Haliade-X program a success for our customers.“.

The benefits for the industry are easy to foresee: the higher the capacity of the machine, the fewer turbines will make up the offshore wind farm, which means less investment in components and auxiliary systems, as well as ‘a discount. on project risks and maintenance costs.

The multinational will move production to France via its subsidiary GE Renewable Energy, with the aim of presenting a demonstration in 2019 and entering the market by 2021.

For this reason, the company will invest around $ 100 million in a new manufacturing facility in Cherbourg, western France, and an additional $ 60 million over the next five years to modernize its production center in Saint -Nazaire.
