wind farm – DesignApplause

ge ginormous haliade-x 14mw wind turbine a great fit for world largest wind farm.

the buoyant offshore wind market wants the biggest and most powerful turbines only.

in the u.s.a., 2021 reopens the prospect of revitalizing a climate agenda which encompasses renewable energy, which, as the name suggests, is always available. global governments and companies have figured out that solar and wind are the best prospects for the future, though location and seasonal variables come into play. for example, solar and wind energy are a strong combination and wind energy is currently a better option to supplement solar energy in winter.

the buoyant offshore wind market wants the biggest and most powerful turbines only. conceived in 2008, the dogger bank wind farm, located off the north-east coast of england, is slated to be the largest in the world with offshore construction expected to begin in 2022 with contractors using specialist vessels to install the offshore infrastructure. the first phase is expected to be operational in 2023. the wind farm will be completed in three phases before reaching full commercial operations in 2026.

two weeks ago ge made an end-of-the year announcement which boasts that their ginormous ge renewable energy’s haliade-x 14 mw had just been awarded for the final phase c. in 2019 the 13 mw model had already been awarded the first two phases a&b. ge renewable energy has been working on this wind turbine concept since 2018.

[ key features ]
> designed for all wind speeds
> recommended for offshore high wind locations
> has a 220-meter rotor and a 107-meter (longer than a football field) blade
> the wind turbine offers three models: a 14 mw, 13 mw or 12 mw
> one rotation could power a household for two days
> one 13w turbine can light up a town of 12,000 homes
> sensors gather data of wind speeds, output, and component stresses
> wind farm first two phases will total of 190 haliade-x 13 mw offshore wind turbines. the final phase features the 14 mw turbine.
> upon completion the wind farm is expected to power up to 6 million homes annually in the uk, equivalent to 5% of the uk’s total electricity demand.

the battle for size continues unabated. siemens-gamesa has announced its next model, the 14mw sg 14-222 dd offshore wind turbine. the race is expected to end at about 20 mw.

note: at this writing the haliade-x is only a prototype

This running feature began in 2008 to develop a story on the state of wind
turbine design. The most current news was inserted February 2010 below.

(top two photos) The world’s largest wind turbine ( in 2008 ) is was the Enercon E-126. This turbine has a rotor diameter of 126 meters (413 feet).

October 2008
The E-126 is a more sophisticated version of the E-112, formerly the world’s largest wind turbine and rated at 6 megawatts. This new turbine is officially rated at 6 megawatts too, but will most likely produce 7+ megawatts (or 20 million kilowatt hours per year). That’s enough to power about 5,000 households of four in Europe. A quick US calculation would be 938 kwh per home per month, 12 months, that’s 11,256 kwh per year per house. That’s 1776 American homes on one wind turbine.

These turbines are equipped with a number of new features: an optimized blade design with a spoiler extending down to the hub, and a pre-cast concrete base. Due to the elevated hub height and the new blade profile, the performance of the E-126 is expected to by far surpass that of the E-112.

One of the more unexpected charms of driving through the Spanish countryside is the proliferation of windmills, especially in the windier, higher plateau areas in the north of the country. We’re not talking about charming medieval ones that Quixote took for giants either — Spain ( below two photos ) is rapidly becoming one of Europe’s leaders in green energy, and broad acceptance of wind power is a big part of it.

In 2007 Spain’s wind power production record was 27% at the time. That seemed like a lot, but a week ago, Spain’s wind turbines produced 40.8% of total demand, or 9,862 megawatts of power.

There’s a catch, though. The previous record was 10,032 megawatts, but that was 28% of total consumption because it happened during a week day and demand was higher. So this new record is a relative record, while the previous one stands as the absolute best in electricity produced. Still, it’s impressive and we hope that others will pay attention and realize that it can be done.

February 2010 ( left ) norway plans to build the world’s most powerful offshore wind turbine like this in 2011.

With a rotor diameter of 475 feet and a height of 533 feet, the 10-megawatt prototype will be roughly three times more powerful than ordinary wind turbines currently in place, hoping the new technology will increase the profitability of costly offshore wind farms.

What if there’s too much wind?
The turbines are built to catch the wind. But what happens if there is too much wind?

There are new generators that are being developed that will better withstand turbulent wind at the same time capable of generating more megawatts. The photo and video below shows one such design.

Global warming has moved our attention to alternative energy generation. We are going to explore what is out there. We want to look at both engineering and aesthetics. Help us grow the story through your comments.
