Liftra’s Blade Way 💫 brings down turbine blades without a crane

By Paul Dvorak | June 15, 2018

Wind turbine service company Liftra launched the Blade Way 💫 in 2017 and introduced it at AWEA’s recent Windpower 2018 conference, as a way to remove and replace wind turbine blades without the time and cost expense of a high-reach crane. Blade Way has a rated capacity of 14.6 tons, and it can work at peak wind speeds of 12 m/s.



These are the main components of a Liftra Blade Way 💫 blade-removal system.

A few of its advantages include:

Reduced mobilization costs that come from its transport in just two standard 40-foot containers. It boasts of universal compatibility thanks to a system that is configurable for all major turbine brands. Its proven wire system and controls are based on the company’s self-hoisting crane. Also, proven blade yokes are based on the last seven years of development in vertical blade installation technology.

The system is comprised of two blade yokes, one for the root end of the blade and one for the tip end, and a hub sling and hoist block.

The components of the Blade Way include:

֍ Blade Way wire system at the turbine hub.

֍ A dual light-weight crane with two arms for hoisting the hub sling and hoist block.

֍ A steel A-frame that attaches to the container for gaining wire height, and the

֍ Wire system that runs from a winch in the container through the A-Frame and both blade yokes up to the hub sling.

Blade Way 💫 brings down a blade for repair.


The Blade Way 💫 sets up at a turbine and removes a blade this way:

1. Workers position the blade to be replaced by turning the rotor to position the faulty blade vertically.

2. The dual light-weight crane is hoisted with the internal turbine crane and mounted inside the nacelle.

3. With the light-weight crane, the hub sling system is hoisted and hooked around the two ‘bunny-ear’ blades.

4. The root yoke and tip yoke are threaded and hoisted along the wires to each end of the vertical blade.

5. The root yoke clamps the root end of the blade, and the tip yoke clamps the tip end, both at precisely defined positions.

6. The blade is lowered to the ground, either with or without the blade bearing.

Once on the ground, the blade or bearing is changed, and the blade can be hoisted back up and reattached to the hub.

CGE Energy obtains U.S. patent for installation process of its WIND-e20 turbine
By Michelle Froese | June 20, 2018

CGE Energy, Inc. announces that the United States Patent and Trademark Office (USPTO) has issued U.S. Patent No. 9,970,410 to the company, entitled, “Installation and erec tion assembly for an elongated structure.” This patent covers the proprietary equipment used for the easy delivery and crane-less installation of CGE Energy’s WIND•e20 vertical-axis wind turbine.

CGE Energy says its WIND•e20 is the world’s only turbine that can be installed, maintained, and removed without a single crane. The turbine can be delivered on the back of a standard flatbed truck, self-erects, and be installed within days.

CGE’s newly issued patent covers a hydraulic installation frame, devised to support their WIND•e20 turbine (or other wind turbines or elongated structures) in a folded arrangement for transportation on a trailer, and to support assembly and erec tion of the turbine. This transport frame enables the turbine to be delivered on a flatbed truck and can lie flat for maintenance without the need of a crane. This diverges from the way traditional horizontal wind turbines are assembled after delivery, which typically require costly cranes for installation and repair.

“This unique patented technology offers easy turbine transportation using a single truck and trailer,” said Bryan Zaplitny, President and CEO of CGE Energy, as well as, one of the solution’s inventors. “The expansion of our intellectual property portfolio is an integral aspect of CGE Energy’s turbine development and commercialization strategy aimed at positioning the WIND•e20 as a first-in-class onsite energy generator.”

This patent adds to the list of other key patents that are owned by CGE, including having a fluid driven turbine that generates power from wind blowing from any direction, its generator and primary components located in the base of the turbine, and hydraulic locking joints within the turbine’s segmented blades, which allow them to collapse flat against the rotor.

CGE Energy’s strategic manufacturing partner for WIND•e20 is Roush, headquartered in Livonia, Michigan. CGE Energy is also working with Roush’s team to patent innovations that will make WIND•e20 an integral part of the community, bringing positive impact to communications, life safety, homeland security and emergency response.

The WIND•e20 uses three segmented blades to produce power from 20 to 100 kW, depending on generator size. The spinning blades appear solid to birds so they fly 🦅 around the working turbine.

General Electric to ramp up wind power investments in Germany

US company General Electric (GE) will ramp up its investment in wind power in Germany in a bid to revive its ailing business, Axel Höpner and Kathrin Witsch write in the Handelsblatt.

The veteran US manufacturer, which has recently got booted from the Dow Jones Industrial Average 30-stock index and is grappling with a waning gas turbine business, wants to increase the number of its employees in Germany and to also boost its investment in the renewable energy branch, the authors write. “We want to grow our wind power business in Germany and in Europe and increase our market share,” GE Germany head Wolfgang Dierker said.

GE, which has an estimated annual revenue of 3.5 billion euros in Germany, has already announced an attack on rival Siemens’s home market in the past, the article says. Its share in new wind power installations now more than doubles that of Siemens and new products, such as the planned 12 GW offshore turbine ‘Haliade-X’, could help GE boost its share further in the next years, it adds.

Yes, that magnus effect is a very real way of harvesting wind for propulsion quite efficiently. 


There are some ships now being fitted with rotor sails to harness wind as a supplement to the engines:

SNIPPET:

Types

Several types of rotor ships can be distinguished. Rotor sail-only ships exist, as do rotor sail-assist (hybrid) ships.[citation needed] Wind Ship Development Corporation has two types of sail-assist designs, for use with different sizes of ships.[2] In practice, most rotor ships have a system with an electric motor that allows the initial start and eventual stop of the rotor by crew.[citation needed] Rotor's rotational speed (i.e., RPM) and direction of spin can also be controlled.[citation needed]

In 2014 Norsepower, a Finnish clean technology and engineering company pioneering the generation of renewable wind energy for the global maritime industry, announced that it will bring to the market the "Norsepower Rotor Sail Solution"[21] which is a completely modernized version of the Flettner rotor. Later in 2014 Norsepower installed the first Norsepower Rotor Sail on Finnish shipping company Bore's RoRo vessel M/V Estraden, and in the end of 2015 Norsepower installed a second similar unit on the same ship. In the beginning of 2016 it was released by Norsepower, that based on the successful sea trials on board M/V Estraden, the technology has potential for fuel savings of up to 20% for vessels with multiple, large rotors traveling on favourable wind routes.[22]

After Norsepower's success with the new design, also Viking Line returned with the rotor concept for their next planned newbuilding. The first image of a new 63,000 GT vessel shows large Flettner rotors which could help the ship to reduce fuel consumption with up to 15%. Letter of intent was signed for the ship in November 2016, awaiting final agreements signing in early 2017.[23] According to a Finnish newspaper, the rotor concept of Viking Line is based on Norsepower Rotor Sails.[24] The latest news from Norsepower is that they have agreed with world's biggest shipping company, Maersk, to start testing the rotor concept in Maersk ships starting beginning of 2018. The managing director of Norsepower, Tuomas Riski, promises their innovation to cut 7–10% of fuel cost leading up to 300000€ savings in big tankers.

In 2018, the MS Viking Grace was retrofitted with a rotor for further testing.[25]

I have the two turbines I bought from Mike after I took my turbine building course. I built one like my little one, and I helped build one like my bigger one, but I had Mike build the ones I bought. Experience is worth something. His simple designs have been proven. Nothing fancy, but plenty of them in service.

For wind, its a relatively easy job to build a turbine from commonly available stuff, if you can get magnets. I went for simple rather than high efficiency.

Sourcing and erecting a tower is a much bigger job, imho, than building a turbine. And with 9mph wind, it's more of a novelty here. But on some days in winter it would no doubt be nice to have a turbine spinning, even here. I have not ever gotten a tower up. Expensive, complicated job, usually requiring a crane. I've been shopping for a good tower deal forever.

I have a low wind Mallard LW built from a repurposed Delco car alternator, and a bigger Mallard SP80.

Nice! micro wind has been mostly destroyed by low cost solar. as mentioned the tower costs and maintenance make them non competitive except on the best wind sites. ...

True. As you said, the advantage a wind turbine could have over photovoltaic is strictly in places where there is a lot of pretty constant wind, particularly at night, I might add.


Great for boats.  Boat mounted turbines max out their performance when you're actually under sail, so its a little different than a land based turbine.

Wind generators really produce power when sailing on a reach. The wind coming off the main sail gets directed back to the wind generator at a higher wind speed causing the wind generator to produce power.

The coast here is windy enough to make them work at anchorage, but that isn't a given everywhere.




I had a hairbrained idea at one time that you could set up a vertical axis wind turbine on a boat that would be speed regulated by a "governor" (sort of like those steam engine governors that slow down or speed up with the centrifugal force of weights) type rotor assemply that would reduce wind exposure when the wind got too strong and increase it to max when the wind was weak. I fancied that the mast of this wind turbine would have to be REALLY strongly attached to the frame of the boat, simply because the gyroscopic effect would be fighting the rocking of the boat in normal seas, trying to tear it loose, all the time.

It was probably a bad idea but I enjoy those types of thought exercises, even if they never come to a hill of beans.  8)

Way back in the early years of the 20th Century an ocean liner owner got the bright idea to use giant gyroscopes bolted to the bottom inside base of the ocean liner so the ship would not rock in high seas. When the ship got into some rough seas, the huge and weighty gyroscopes (there were around four of them placed equidistantly along the bottom inside), each as tall as three humans, tore the bolts off. Those dadgum giant gyroscopes just did not wanna go where the ship was going.

Of course, that was the end of that idea.

I had a flight student that was an ocean liner officer. He invited me on board and showed me the bridge. Since he was learning to fly and knew the ship controls would interest me, he showed me how the "wings" of the ocean liner worked. The vanes under the water line are used to generate hydrodynamic "lift" up or down, like ailerons on an aircraft (vanes on the port side work opposite the vanes on the starboard side). He explained those vanes keep the liner from rocking much in rough seas. Let me tell you, they are not that small, even though they are much smaller relative to the ship body than aircraft wings are to a fuselage. Those vanes are very tough as well. If water/wave pressure from a surprise sea can tear off a ship's rudder, those hydrodynamic vanes need to be super strongly attached.

I guess that's the way they finally went when the gyroscope idea didn't work out. That was way back in 1970. I don't know if they still use "wings" under water to stabilize ocean liners.

Agelbert NOTE: This article is 5 years old, but worth your attention. Perhaps it has not gained much attention, simply because the units are not for huge wind turbines that get all the news. Nevertheless, they are doing a great service for smaller installations like homes and farms (see video at the end of this article and 2017 press release).
Shifting Gears on Wind Turbines

To gear or not to gear?

Most wind turbines have gearbox transmissions that connect the slowly spinning turbine with the speed-hungry generator. But gearboxes have disadvantages: they’re noisy, complex, and prone to failure. Gearboxes need regular maintenance and lubrication, increasing their total cost of ownership. Some manufacturers have opted for gearless direct-drive turbines, but there’s a trade-off: because the shaft spins slowly, they require much larger permanent-magnet generators, increasing the weight and initial cost of the turbines. A new technology may capture the best of both designs.

Windtech has partnered with Future Force LLC to build a turbine based on the Zero Contact TransmissionTM (ZCT) patented by Future Force. The technology uses a transmission of sorts, but instead of mechanical gears, belts, or chains, the ZCT uses neodymium permanent magnets to make the generator in the turbine spin five times faster than the rotor. Lab tests conducted at the University of St. Thomas (Minnesota) have shown the ZCT to be 98% efficient at transferring energy from its input to its output.


As shown above, the rotor drives the main shaft, which is magnetically coupled (via the ZCT) to five independent generators, each spinning five times faster than the rotor. (The picture only shows four generators, but their documentation says five. There must be one in the middle.) This provides  redundancy; the turbine could withstand the failure of one or two generators and still produce some power. The turbine is capable of generating substantial energy at low wind speeds; its peak power occurs when the wind speed is 8.1 m/s (18 mph), where comparable turbines require speeds in excess of 12 m/s (27 mph) to achieve peak output. Its startup speed is a meager 2.2 m/s (5.0 mph). It’s designed for locations with average wind speeds of 4 m/s (8.8 mph), which makes wind power viable in 50% more places.


Windtech is currently testing a prototype of its 100E 10 kW turbine (pictured below) in Glencoe MN. They plan to sell the 100E at a price that’s competitive with other units of similar size, making it more likely that customers will take this turbine out for a spin.

Zero-Contact Transmission logs 15,000 hours of operation 👀   

June 19, 2017

Future Force Zero Contact Transmission (ZCT) hits 15,000 hour milestone. The ZCT designed and built for WindTech, Inc. just surpassed 15,000 hours of operation with NO lubrication.   

The ZCT utilizes magnetic propulsion so there is no friction or need for lubricants. Mike Tkadlec, founder of Future Force and inventor of the Zero Contact Transmission said, “to deploy a ZCT in a wind turbine is perfect for proving the viability of a high torque magnetic propulsion transmission whichoperates at 35% greater efficiency  than a standard oil-encased gearbox. This is a major breakthrough in advancing to the next size ZCT for mW generators without lubrication.”

Ørsted Officially Opens 573 Megawatt Race Bank Offshore Wind Farm

June 14th, 2018 by Joshua S Hill

Danish offshore wind energy developer Ørsted officially opened the 573 megawatt (MW) Race Bank Offshore Wind Farm Wednesday, which will provide over half a million UK homes with clean electricity.


The Race Bank Offshore Wind Farm has had something of a long history, and was only pulled out of trouble in late 2013 when DONG Energy (now known as Ørsted) acquired 100% ownership in the project from British multinational energy and services company Centrica.

“Race Bank fits very well into our existing pipeline of offshore wind projects and will contribute to the achievement of our strategic target of constructing 6,500 MW by 2020,” said Samuel Leupold, Executive Vice President of DONG Energy Wind Power, at the time. “The addition of up to 580 MW to our UK project portfolio underlines our commitment to the UK market in general, and to the UK offshore wind sector in particular.”


A year and a half later, DONG Energy awarded a wind turbine order to Siemens (now Siemens Gamesa) to provide 91 of its 6 MW wind turbines for the project. Located 32 kilometers off the British eastern coast, Race Bank was one of the big projects announced through the early part of this decade, but has since been eclipsed by much larger projects with much bigger wind turbines.

At the end of 2016, DONG Energy divested 50% ownership in the project to the Macquarie European Infrastructure Fund 5 and Macquarie Capital, the principal investment arm of Macquarie Group in a deal that was worth £1.6 billion ($1.2 billion).

And finally, at the beginning of February this year, Ørsted announced that Race Bank had reached full power output across all of its 91 wind turbines and had already generated 1 terawatt-hour (TWh) of power 👀 since construction had begun.

video at article link of Race Bank Inauguration  8)
 
The project was therefore officially opened at a ceremony in Grimsby on Wednesday, home to Ørsted’s East Coast Hub, the UK’s largest offshore wind Operations and Maintenance (O&M) base. The project, beyond being a massive provider of clean electricity, also makes use of a new way of carrying out offshore maintenance, using a Service Operation Vessel that remains offshore with technicians working 14 days and 14 days off. 


“Race Bank is a fantastic infrastructure project and underlines Ørsted’s contribution to the UK’s energy transition. It’s also another clear signal of our firm commitment to Grimsby and the Humber, and the UK supply chain for offshore wind,” said Matthew Wright, Managing Director at Ørsted UK. “Race Bank is a hugely significant and innovative project, featuring the first-ever turbine blades to be made in Hull and becoming our first wind farm in the UK to be operated using a new Service Operation Vessel. It’s also one of the fastest projects we have ever built, with a fantastic safety record, and this is testament to the hard work of the project team and the great relationship we have with our partners.

“Powering over half a million homes every year, Race Bank is another positive step towards delivering the UK’s decarbonised energy system of the future.”

11 Turbines Successfully Installed at Wind Farm Trump 🦀 Tried to Block  ;D

SNIPPET:

The world's most powerful wind turbines have been successfully installed at the European Offshore Wind Deployment Centre (EOWDC) off Aberdeen Bay in Scotland's North Sea.

The final turbine was installed on Saturday just nine weeks after the first foundation for the 11-turbine offshore wind farm was deployed, according to the developers Vattenfall.

Incidentally, the project was at the center of a contentious legal battle waged—and lost—by Donald Trump, before he became U.S. president. Trump felt the "ugly" wind turbines would ruin the view of his Menie golf resort.

"I am not thrilled," Trump said in 2006, as quoted by BBC News. "I want to see the ocean, I do not want to see windmills."

But in 2015, the UK Supreme Court unanimously rejected Trump's years-long appeal against the wind farm, which now stands 1.2 miles from his luxury golf course.

Van Oord 💫 Wins Offshore Wind 💨 Contract in Taiwan


May 30, 2018 by gCaptain

Map shows the location of the Yunlin offshore wind farm.

Dutch marine contractor Van Oord announced on Wednesday that it has been selected as the preferred contractor for a large 640 MW offshore wind project in Taiwan.

The Yunlin offshore wind project is being developed by German wind developer wpd.

Van Oord is responsible for the design, manufacturing and installation of the wind farm’s eighty foundations, which will be constructed eight kilometers off the coast of Taiwan’s Yunlin prefecture. Work is expected to start immediately. 

Taiwan Emerging as Battleground to Expand Offshore Wind in Asia

Van Oord says the contract has a value of approximately EUR 500 million.

The Taiwanese government aims to install 5.5 GW of offshore wind projects by 2025.

The installation of the first foundations for the Yunlin project are expected to start in early 2020.

Dawn of Asia’s Offshore Wind Boom Lures Japanese Trading Houses

For Van Oord, the Yunlin project represents its first offshore wind project in Taiwan, as well as its first outside of Europe.

In Asia, and especially in Taiwan, large investments are being made in offshore wind. The Yunlin project is a great opportunity for Van Oord to show our expertise outside Europe. We look forward to working with our local partners to enable the energy transition of Taiwan,” commented CEO Pieter van Oord.

`Dawn’ of Asia’s Offshore Wind Boom 🌟 Lures Japanese Trading Houses

May 29, 2018 by Bloomberg

SNIPPET:

“Asia is at the dawn of development of its offshore wind market,” Yoshio Kometani, chief operating officer of Mitsui’s infrastructure projects business unit, said in an email. “Taiwan is especially promising as it has favorable natural conditions and the government is taking initiative to improve investment and development opportunities.”

Buffeted by strong breezes in the Taiwan Strait, the island has emerged as a hot spot for clean power projects as President Tsai Ing-Wen works to phase out nuclear energy while adding 25 gigawatts of renewable energy by 2025. The island is seeking to boost offshore wind capacity to 5.5 gigawatts over the same timeframe, from just 8 megawatts.

In Japan, the government is working on legislation that standardizes offshore wind development guidelines and streamline the approval process for new projects. In March, the country’s Ministry of Economy, Trade and Industry updated its offshore wind map with more data on conditions and the agency is accelerating the environmental impact assessment process.

Globally, there are about 18 gigawatts of offshore wind capacity and Europe accounts for more than 80 percent of that, with the rest mostly in Asia, according to Bloomberg New Energy Finance. Asia will add 3.5 gigawatts of offshore wind capacity in 2030, more than double the 1.5 gigawatts to be added in Europe the same year, according to estimates in a December report from BNEF.

To be sure, most of Asia’s offshore wind development is occurring in China, a place where historically Japanese companies have a small footprint. The world’s largest energy user is ranked third globally for offshore wind capacity with about 2.8 gigawatts as of last year, after the U.K. and Germany, according to BNEF.

Japanese trading houses have been making moves into offshore wind in overseas markets for years, gaining experience to participate the coming Asia boom. Marubeni owns a stake in a project in the U.K. and Sumitomo Corp. owns parts of two Belgium and two other U.K. offshore wind farms.

Mitsubishi, which will start construction of a 950-megawatt wind project off the U.K. coast with partners this year, aims to double its renewable output so that it accounts for about 20 percent of its total power production by 2030. Offshore wind will play an important role in that expansion, according to Yusuke Takeuchi, who heads a power business development team at Mitsubishi.

Can we get 100% of our energy from renewable sources? 

By Michelle Froese | May 18, 2018

This article comes from Science Daily, with materials provided by Lappeenranta University of Technology.


Scientists have demonstrated that there are no roadblocks on the way to a 100% renewable future.

֍ Is there enough space for all the wind turbines and solar panels to provide all our energy needs?

֍ What happens when the sun doesn’t shine and the wind doesn’t blow? 🤔

֍ Won’t renewables destabilize the grid and cause blackouts?    

In a review paper last year in the high-ranking journal Renewable and Sustainable Energy Reviews, Master of Science Benjamin Heard 🐉 and colleagues 🦕 🦖 presented their case  against 100% renewable electricity systems. They doubted the feasibility of many of the recent scenarios for high shares of renewable energy, questioning everything from whether renewables-based systems can survive extreme weather events with low sun and low wind, to the ability to keep the grid stable with so much variable generation.

Now scientists have hit back with their response to the points raised by Heard and colleagues. The researchers from the Karlsruhe Institute of Technology, the South African Council for Scientific and Industrial Research, Lappeenranta University of Technology, Delft University of Technology and Aalborg University have analysed hundreds of studies from across the scientific literature to answer each of the apparent issues.

They demonstrate that there are no roadblocks on the way to a 100% renewable future.

“While several of the issues raised by the Heard paper are important, you have to realise that there are technical solutions to all the points they raised, using today’s technology,” says the lead author of the response, Dr. Tom Brown of the Karlsruhe Institute of Technology.

Quote
“Furthermore, these solutions are absolutely affordable, especially given the sinking costs of wind and solar power,” adds Professor Christian Breyer of Lappeenranta University of Technology, who co-authored the response.

Brown cites the worst-case solution of hydrogen or synthetic gas produced with renewable electricity for times when imports, hydroelectricity, batteries, and other storage fail to bridge the gap during low wind and solar periods during the winter. For maintaining stability there is a series of technical solutions, from rotating grid stabilisers to newer electronics-based solutions. The scientists have collected examples of best practice by grid operators from across the world, from Denmark to Tasmania.

Furthermore, these solutions are absolutely affordable, especially given the sinking costs of wind and solar power.

The response by the scientists has now appeared in the same journal as the original article by Heard and colleagues.

There are some persistent myths that 100% renewable systems are not possible,” says Professor Brian Vad Mathiesen of Aalborg University, who is a co-author of the response. “Our contribution deals with these myths one-by-one, using all the latest research.

Time-Lapse: World’s Most Powerful ⚡ Offshore Wind Turbine Installed Off Scotland

May 16, 2018 by gCaptain

A time-lapse video has been posted online showing last months installation of the world’s most power wind turbine at Vattenfall’s European Offshore Wind Deployment Centre located just off the north-east coast of Scotland in Aberdeen Bay.

The turbine is the first of 11 to be deployed at the “ground-breaking” facility and one of two turbines at the wind farm that have been modified to generate 8.8MW of clean energy from the less powerful but still impressive 8.4MW versions.

Vattenfall says the installation, which took place on April 9, marks the first time an 8.8MW model has been deployed commercially in the offshore wind industry.

Together with the nine 8.4MW turbines, the European Offshore Wind Deployment Centres (EOWDC) will have an output to 93.2MW, equivalent to 70% of Aberdeen’s domestic electricity demand or approximately 134,128 tonnes of CO2 per year.

MHI Vestas has specially designed the V164-8.4 MW and V164-8.8 MW turbines which all have a tip height of 191 meters. Each blade is 80m long and the 164m rotor has a circumference larger than that of the London Eye’s.

EOWDC project director at Vattenfall, Adam Ezzamel, said: “The first turbine installation is a significant achievement and credit to the diligence and engineering know-how of the project team and contractors. For it to be one of the 8.8MW models makes it an even more momentous moment because it further endorses the EOWDC as a world-class hub of offshore wind innovation.”

The turbines were transported from Esbjerg to Aberdeen by Swire Blue Ocean’s wind farm installation vessel, the Pacific Orca, which lifted the turbines into position on the previously-installed foundations.

US Wind Development Surges As Pipeline Exceeds 30 Gigawatts

May 4th, 2018 by Joshua S Hill

SNIPPET:

The demand for US wind energy surged through the first quarter of 2018, pushing the country’s wind development pipeline to over 33 gigawatts (GW), according to the American Wind Energy Association, which tracked new announcements of over 5,500 megawatts (MW).

The American Wind Energy Association (AWEA) published its US Wind Industry First Quarter 2018 Market Report this week, highlighting the continued demand for “affordable, reliable” wind energy across the United States. Specifically, AWEA tracked 3,560 MW worth of signed Power Purchase Agreements (PPAs) by utility and non-utility customers — the strongest quarter for PPAs AWEA has seen since it began tracking them in 2013. AWEA also tracked new project announcements worth 5,523 MW for the first quarter, pushing the amount of wind power capacity in various stages of development and construction to a total of 33,449 MW — a 40% year-over-year increase and the highest level AWEA has seen since it has been tracking both categories in 2016.

“Word is out that wind power is an excellent source of affordable, reliable and clean energy,” said Tom Kiernan, CEO of AWEA. “Our industry is consistently growing the wind project pipeline as leading companies, including utilities and brands like AT&T and Nestle, keep placing orders. Strong demand for wind power is fueling an economic engine supporting a record 105,500 U.S. wind jobs in farm and factory towns across the nation.”

However, it is also worth looking at the country’s cumulative and quarterly additions, which shows that the last few years have actually seen a decline in yearly wind capacity additions, and fluctuating quarterly figures as well.

MHI Vestas has been awarded a contract to install the world’s most powerful offshore wind turbines off the coast of Belgium.

The installation of the record-setting 9.5 MW turbines is planned for late 2019 at the Northwester 2 offshore wind farm in the North Sea.

The 224 MW Northwester 2 project is the fourth collaboration between Parkwind and MHI Vestas. The wind farm will comprise 23 turbines and provide enough clean energy to power 220,000 Belgian homes.

“The Northwester 2 timing and general schedule is very challenging in the light of the timing wanted by the Belgian government. This challenging timeline has played an important role in the choice for MHI Vestas as turbine supplier having the capability of delivering the V164-9.5 MW. Parkwind is very delighted to have MHI Vestas for the fourth time as a partner,” commented the co-CEO’s of Parkwind, Eric Antoons & François Van Leeuw.

The conditional order announcement, which includes a service agreement, comes as the government has recently announced it will double offshore wind capacity in Belgian territorial waters, up to 4 GW by 2025.

The V164-9.5 MW from MHI Vestas Offshore Wind is the most powerful and commercially available wind turbine in the world. With blades that are 80 m in length, one turbine can power 9,500 Belgian homes.

Parkwind today operates 552MW in the Belgian territorial waters and has a pipeline of another 554MW offshore in Belgium and Ireland.

Siemens Gamesa To Repower 508 Megawatts ⚡ Of US Wind 💨 💫

April 26th, 2018 by Joshua S Hill

Spanish wind energy giant Siemens Gamesa Renewable Energy has been awarded the contract to repower three wind farms in the United States for a total of 508 megawatts (MW), extending the lifespan and reliability of projects which would otherwise have reached their life’s end.

Siemens Gamesa announced on Wednesday that it had been awarded two separate contracts with US utility NextEra Energy Resources to repower three wind farms across Texas for a total capacity of 508 MW. The deal confirms the company as one of the world’s leading wind energy operations and maintenance (O&M) companies, a market which will only continue to evolve and grow in importance over the next decades. In total, Siemens Gamesa has 55 gigawatts (GW) under service around the world.

Indian Mesa Wind Energy Center

The first of the new contracts signed between Siemens Gamesa and NextEra is for the repowering of 362 of Vestas’ V47 wind turbines at the Indian Mesa and Woodward wind farms in Texas for a total capacity of 240 MW.

Siemens Gamesa will overhaul the V47 turbines to upgrade hardware and control systems and resulting in an increased output of 710 kilowatts (kW), up from the previous 660 kW, as well as extending the life of the turbines for another 10 years with an increased availability. The company will upgrade the electrical and electronic components of the wind turbines, subsequently improving performance and increasing its lifetime energy production. The overhaul is expected to be completed by the end of the year and the turbines will remain operational during the process.

“We highly value our continued partnership with NextEra Energy Resources,” said Mark Albenze, CEO of Siemens Gamesa’s Service Business Unit. “As a multi-brand service provider, we can enhance the performance of V47 turbines with our cutting-edge solutions by delivering maximum performance and optimal energy output, allowing NextEra Energy Resources to achieve the best possible return on their investment.”

King Mountain Wind Energy Center

The second agreement signed between Siemens Gamesa and NextEra is for the repowering of 210 units of the legacy Bonus 1.3 MW wind turbine at the King Mountain Wind Energy Center in Texas, making it the first time a 1.3 MW turbine has ever been repowered.

“Repowering the Bonus units demonstrates Siemens Gamesa’s commitment to maximizing value for our customers throughout an asset’s lifecycle,” added Mark Albenze. “The upgrades will improve the reliability of these units by modernizing the turbines to reduce maintenance requirements and sustain overall site availability.”

Harnessing the Wind: ‘Viking Grace’ Becomes First Passenger Ship to Use a Rotor Sail for Wind-Assisted 💨 Proplusion

April 11, 2018 by Mike Schuler

One of the world’s most eco-friendly passenger vessels is about to get a whole lot more eco-friendly.
Finnish shipping line Viking Line has equipped its LNG-fueled Viking Grace with a rotor sail to help reduce the vessel’s environmental impact even more by harnessing the power of the wind.

The 57,565 GT Viking Grace, which has been in operation since 2013, is already considered one of the most eco-friendly cruise ferries in the world, but the addition of a rotor sail will help the vessel cut fuel consumption and reduce emissions even further when its begins wind-assisted voyages in the Baltic Sea between Turku, Finland and Stockholm, Sweden beginning on Thursday.

Developed by the Finnish company Norsepower Oy Ltd, the Rotor Sail Solution installed on the Viking Grace is a modernized version of the Flettner rotor; a spinning cylinder that uses the Magnus effect to harness wind power to propel a ship. The company first announced the project to install one of its devices aboard Viking Grace in January 2017.

While rotor sails have been in use on commercial ships before, the Viking Grace will be the first passenger ship in the world to be equipped with the technology.

The cylindrical rotor sail installed on the vessel 24 meters in height by 4 meters in diameter. As the rotor is spinning, the passing air will flow with a lower pressure on one side, creating a pressure difference that will propel the vessel forward.

Norsepower’s Rotor Sail Solution is already in commercial use on board the Bore’s MV Estraden, a 9,700 DWT Ro-Ro carrier, which has achieved a 6.1% reduction in fuel consumption through use of the rotor sails, according to Norsepower. The technology is fully automated, sensing whenever the wind is strong enough to deliver fuel savings, at which point the rotors start automatically.

Aboard the MS Viking Grace, the rotor sail will reduce the vessel’s carbon dioxide emissions by up to 900 tonnes per year, depending on the wind conditions, Viking Line says.

“For Norsepower, it’s an honour to be able to make the M/S Viking Grace even more environmentally-friendly by means of our novel rotor sail technology. The last traditional windjammers in the world were owned and operated by shipping companies based in Åland, so it’s fitting that Åland-based Viking Line should be a forerunner in launching modern auxiliary sail technology,” says Tuomas Riski, CEO of Norsepower.

In addition to the Viking Grace, Viking Line has also announced it will also utilize wind propulsion in the company’s new vessel, which is due for delivery 2020. Built in China, the passenger ship will be equipped with two mechanical rotor sails supplied by Norsepower.

Record-Breaking Wind 💨 Power Output  ⚡ in Scotland Sufficient for 5 Million Homes

By LORRAINE CHOW OF ECOWATCH ON BUZZFLASH AT TRUTHOUT

SNIPPET:

Scotland, which is fast on track to get 100 percent of its electricity via renewable energy by 2020    , has broken another wind power record.

The country's onshore wind turbines provided more than 5.3 million megawatt hours of electricity to the National Grid during the first three months of 2018, an impressive 44 percent increase compared to the same period last year, according to an analysis of WWF Scotland wind power data by WeatherEnergy.

Over that first quarter, enough wind power was generated to supply the equivalent of five million homes with low-carbon electricity. The best day was on March 1, when 110,000 megawatt-hours of wind power could have supplied 173 percent of the nation's entire electricity demand.

Last year, First Minister Nicola Sturgeon announced plans to end the sale of new gas and diesel-powered cars by 2032, eight years ahead of the UK government target  ;D. And unlike England, fracking was permanently banned in Scotland last year and has technically been under halt since 2015.

The Biggest Problem for Offshore Wind in the United States Might Be the Ports

April 9, 2018 by Bloomberg

By Jim Efstathiou Jr. (Bloomberg) — U.S. offshore wind developers have a space problem.

SNIPPET:

Massachusetts has solicited bids for as much as 800 megawatts of offshore wind.

Finding locations big enough to assemble the huge towers and turbines and handle ships that can deliver the hardware to offshore farms is the biggest hurdle for companies eyeing a slice of the emerging market, according to Jeff Grybowski, chief executive officer of Deepwater Wind LLC, which developed the first U.S. offshore project.

“Our real challenge is finding enough port space to fit these projects,’’ Grybowski said Monday in an interview at the BNEF Future of Energy Summit in New York. Deepwater Wind used four ports to build the five-turbine, 30-megawatt Block Island wind farm off the coast of Rhode Island, he said.

Wind Power ⚡ Keeps Breaking Records In Central U.S 

By BRIAN GRIMMETT • MAR 26, 2018

Early on the morning of March 16, wind provided 60 percent of the region’s electric needs. That number set a record 🌟, breaking an earlier one set only a week and a half earlier.

Wind power also recently set records for highest peak generation at 15,690 MW and continuously sustained generation of more than 13,000 MW for three days.

The Southwest Power Pool (SPP) oversees the region’s power grid, covering part or all of 14 states from as far south as Texas all the way to North Dakota. SPP COO Carl Monroe said his biggest concern with continued wind growth is its unpredictability. Sometimes it produces a lot electricity, and sometimes very little.

“The holy grail in a lot of people’s minds is storage and does storage get to a cost where it’s competitive to where you can use it to offset the intermittency of the wind,” Monroe said.

In 2017, wind provided a little more than 22 percent of all electricity in the region, second only to coal.

Poland, One of Europe’s Biggest Polluters, Is Turning Toward Offshore Wind Power 

March 21, 2018 by Bloomberg

SNIPPET:

By Ewa Krukowska and Maciej Martewicz (Bloomberg) — After decades of prompting coal as the guarantor of national energy security, Europe’s fourth-biggest greenhouse-gas polluter is shifting to embrace wind power.

PGE SA, which is Poland’s largest utility, wants to turn to turbines to harness the breezes in the Baltic Sea and eventually supply 2.5 gigawatts from the technology by 2030. It is considering teaming up with one of the top European players in the project and is also working to speed up investments in generation plants fired by gas and those that use combined heat and power technology, according to Monika Morawiecka, the company’s director of strategy.

The moves reflect a plunge in the cost of wind turbines and rising costs for emissions permits. With the European Union determined to clamp down on climate-damaging fossil fuels, even the most polluting utilities are starting to look at how to clean up their industries.

Agelbert NOTE: In addition to providing higher energy harvesting, the BTC wind turbine blade, pictured below, promises to reduce or eliminate damage from hurricane force winds due its ability to twist without structural failure.


Turbine blades that bend & twist can improve their power ⚡ output

March 9, 2018 Paul Dvorak

This article comes from the Fraunhofer Research News / 1.3.2018

The share of the overall electricity market made up by wind energy continues to grow year after year. The giant rotor blades are one central part of a turbine. In the “SmartBlades” project, the Fraunhofer Institute for Wind Energy Systems IWES and its partners developed a rotor blade, which, thanks to an innovative bend-twist coupling, is able to make more efficient use of large fluctuations in wind strength. In the follow-up project “SmartBlades2”, the concept will undergo experimental tests using a demonstrator.

The BTC blade in the extreme load test: The loads are applied via three hydraulic cylinders.

More than 28,000 wind turbines with a total output of 50 gigawatts are currently in operation in Germany: This equates to a 12.3% share of the total electricity production in Germany in 2016. This figure places the German wind energy sector at the top of the European league table, as confirmed by the German Wind Energy Association’s data. The current focus of research is now on developing this technology even further. And the Fraunhofer Institute for Wind Energy Systems IWES, based in Bremerhaven, is leading the way here. Within the framework of the joint “SmartBlades2” project, researchers have turned their attention to the bend-twist coupling (BTC) concept for rotor blades. The passive working coupling adapts continuously to the wind forces acting on the rotor blade. When the wind loads become too high, the bend-twists reduces the forces affecting the structure.

The rotor blades of conventional wind turbines react to changing wind strengths very slowly. A rotor blade measuring up to 85-meters long describes a circular area of 22,670 m², that’s the equivalent of four soccer pitches  :o. The wind strengths within this area can vary greatly. The pressure acting upon the blade pointing upward, for example, can be very different from the pressure on the lower blade. Conventional rotor blades cannot compensate for a single gust of wind as they are too rigid to twist. This means if there is a gust when the wind is already strong, the turbine operators turn the rotor blades completely away from the wind. This results in long downtimes during which no electricity is produced.

“The demonstrator BTC blade developed as part of this project is swept back whilst the blade tip is offset slightly to the rear in the direction of rotation. The 20-meter-long rotor blade is therefore able to rotate slightly around its own axis should strong gusts occur in order to mitigate the wind pressure to a certain degree,” explained the IWES technology coordinator for BTC blades, Dr. Elia Daniele. This reduces the forces acting upon the blade and, ultimately, the entire turbine. By using BTC blades on a newly planned wind turbine, the overall turbine weight can be reduced as the structure is subjected to lower loads. In case of existing turbines, the retrofitting of BTC blades allows the rotor diameter to be increased without having to adapt the other turbine components. This results in an increase in revenue thanks to a greater wind yield.

Insufficient transmission capacity continues to hold the US wind industry back from realizing its full potential

A Missouri judge recently ruled that the state’s utility commission “erred” in not approving the Grain Belt Express. The transmission line would transport wind from Kansas to Indiana, passing through Missouri on the way. The fate of the line now rests in the hands of the state Supreme Court. The demand for transmission to transport wind power is high -- when the Grain Belt Express was first announced, it received 4.5 times the line’s capacity in service requests from wind generators.

GE Unveils the World’s Most Powerful Wind Turbine  :o 

March 1, 2018 by Bloomberg

GE says the Haliade-X offshore wind turbine will feature an industry-leading 12 MW direct drive generator, enough to power up to 16,000 households annually. Image credit: GE

By Jeremy Hodges (Bloomberg) — GE Renewable Resources said it’ll spend as much as $400 million over the next few years to build an offshore wind turbine almost 100 meters taller than the Washington Monument.

The new turbine, dubbed Haliade-X, will measure 260 meters (853 feet) tall, the company said. The blades, manufactured by LM Wind Power, will be longer than a soccer field.

One 12-megawatt turbine will generate as much as 67 gigawatt hours a year, which is enough to power 5,000 households, GE said. Bigger turbines need fewer foundations and less complex grid connections than smaller units. That means a wind farm’s layout can be made more efficient, and fewer machines means less maintenance.

GE said it’ll supply the first nacelle for a demonstration in 2019 and ship the first turbines in 2021.


“The renewables industry took more than 20 years to install the first 17 gigawatt of offshore wind,” said Jerome Pecresse, president and chief executive officer of GE Renewable Energy. “Today, the industry forecasts that it will install more than 90 gigawatts over the next 12 years. This is being driven by lower cost of electricity from scale and technology.”

The costs of building and producing offshore wind farms have fallen dramatically in recent years making subsidy-free projects a reality. In 2017, the German and Dutch electricity regulators approved bids to build what will be the first offshore wind farms that depend entirely on market prices instead of government support and subsidy.

“It is important to be mindful of the challenges that come with bringing a 12-megawatt turbine to market,” said Keegan Kruger, a London-based Bloomberg New Energy Finance analyst.

Foundation manufacturers and installation vessel suppliers will need to adapt to the shift toward bigger turbines, while investors must learn to finance gigawatt-scale projects operating machines that have never been used, he said.

AWEA Releases Underwater Footage of Block Island Wind Farm’s Artificial Reef

Recreational fishing industry becomes unlikely supporter of offshore wind in New England.  ;D

February 14, 2018

By Jennifer Runyon Chief Editor

         
When the Block Island Wind Farm (BIWF) foundations were put in place in 2015, many fishermen were worried. How would these giant metal formations set into the ocean change the game for commercial and recreational fisherman? Would they restrict fishing, causing these small business-owners to lose money and their livelihood?

After 6 months, their worries were starting to be alleviated and after just one year, they were completely gone. According to Chris Hobe, who has been fishing on the island since 1979, “within six months you had seed mussels,” he said in a webcast announcing the release of the footage. After one year those seed mussels had turned into a deep, thick coating of mature mussels, on which smaller fish feed, attracting the fish that feed on them and on and on up the food chain. Hobe added that a hammerhead shark was hunting in the region last summer for more than a week.

Another added bonus according to Hobe was the increased tourism that the turbines attracted. On a whim, his company offered to take the general public on tours around the turbines so they could see them up close. He never imagined the interest that would draw. By the end of the the 2017 summer season, Hobe said his company had stopped offering fishing excursions and was just doing sightseeing tours.

Engaging with all stakeholders is one of the most important aspects of building an offshore wind farm. Case in point is the now failed Cape Wind project, with its deep-pocketed opposition that killed the project after more than 10 years of lawsuits. In that case opponents were mainly concerned with views.

But if the underwater footage of the Block Island Wind Farm is any indication, fisherman, at the very least, should have no concerns with planned offshore wind farms near them. 

“We’re in the process of unlocking an entirely new American ocean energy resource with offshore wind. As the industry scales up in the U.S., communities up and down our coasts, especially in the Northeast, will want to know what offshore wind means for them,” said Stephanie McClellan, Director for the Special Initiative on Offshore Wind (SIOW), which was a partner on the project.

“When it comes to fishing, the science is convincing, but ultimately seeing is believing. That’s why we took an underwater videographer to Block Island to see for ourselves.”

Hywind Scotland, World’s First Floating Wind Farm, Performing Better Than Expected

February 16th, 2018 by Joshua S Hill

The world’s first floating wind farm, the 30 megawatt Hywind Scotland, is outperforming expectations and operating at levels consistently above that of its seabound offshore brethren, according to project developer Statoil.

First approved by the Scottish Government back in late 2015, the 30 megawatt (MW) Hywind Scotland floating offshore wind farm is made up of five 6 MW wind turbines floating 25 kilometers off the coast of Peterhead, in Scotland. The project began generating electricity in October of last year.


According to project developer Statoil, a Norwegian multinational oil and gas company, Hywind Scotland isn’t just generating electricity, it’s been doing so at a level that surpasses expectations through its first three full months of production and beating out the average accomplished by bottom fixed offshore wind farms.

It’s important at this point to remember that a wind turbine doesn’t generate 100% of its potential electricity capacity 24 hours, 7 days a week — to do that would require very disturbing wind conditions that pretty much don’t exist anywhere on earth. According to Statoil, wind farms that are affixed to the seafloor generally generate at around 45 to 60% — in other words, they are generating 100% of their potential electricity capacity around 45 to 60% of the time.

Conversely, according to Statoil, during November, December, and January, Hywind Scotland generated at an average of 65% — and has encountered hurricane Ophelia in October, Storm Caroline in early December, and waves in excess of 8.2 meters. Storm Caroline did force the farm to shut down during the worst of the winds for safety reasons, but the turbines automatically resumed operation afterwards.


“We have tested the Hywind technology in harsh weather conditions for many years and we know it works,” said Beate Myking, senior vice president of offshore wind operations in Statoil. “But putting the world’s first floating wind farm into production comes with some excitement. Therefore, it is very encouraging to see how well the turbines have performed so far.

“Hywind Scotland’s high availability has ensured that the volume of electricity generated is substantially higher than expected. In addition, it has delivered without any HSE incidents.”

The importance of these results is more than just representative of the success of Hywind Scotland.   

“Knowing that up to 80% of the offshore wind resources globally are in deep waters (+60 meters) where traditional bottom fixed installations are not suitable, we see great potential for floating offshore wind, in Asia, on the west coast of North America and in Europe,” explained Irene Rummelhoff, executive vice president for New Energy Solutions in Statoil. “We are actively looking for new opportunities for the Hywind technology.”

By Jeremy Hodges and Jessica Shankleman (Bloomberg) — Europe’s wind-power industry expects new French offshore turbine installations to overtake the U.K. and Germany by 2022, boosting President Emmanuel Macron’s pledge to increase renewable energy.

Construction off the French coast is expected to ramp up from 2020 and turn the country in the fourth-biggest offshore wind generator with about 4.3 gigawatts capacity by 2030, according to the Brussels-based WindEurope industry group.

Macron has repeatedly promised to turn France into a green energy leader 🌟 and reduce the country’s reliance on nuclear power. He’s trying to cut through bureaucratic red tape that has delayed offshore wind projects tendered in 2012. His government said in November that it aims to trim offshore project development to less than seven years from more than a decade.

British Offshore Wind Project Draws Investment Heavyweights

February 6, 2018 by Reuters

reuters logoBy Nina Chestney and Christoph Steitz LONDON/FRANKFURT, Feb 6 (Reuters) – British offshore wind project Triton Knoll has attracted the interest of several large investment funds, according to three sources familiar with the matter, in a sign of the growing competition for assets in the fast-changing sector.

German energy group Innogy , owner and developer of the planned 2-billion-pound ($2.8 billion) farm off the coast of eastern England, is looking for partners to get it off the ground.

The project has drawn interest from a number of infrastructure and pension funds, including Australia’s Macquarie , Switzerland’s Partners Group and Denmark’s PFA Pension, the three sources told Reuters.

Innogy, Macquarie, Partners Group and PFA all declined to comment on Triton Knoll. Offshore projects of this size typically have more than one investor alongside the developer.

The demand for the 860-megawatt (MW) Triton Knoll is indicative of the wider interest in offshore wind projects among funds. The returns on offer – typically 6-9 percent – outstrip interest rates, while competition has been heated up by the fact the number of profitable new projects becoming available is declining because fewer can secure government subsidies.

New data from industry group WindEurope, provided to Reuters ahead of its publication, reflects this rising institutional investor interest, as well as the decline in the building of offshore farms.

Infrastructure funds, pension funds and asset managers accounted for 35 percent of offshore M&A activity in Europe in 2017, up from 27 percent in the previous year, according to the data. At the same time, spending on new offshore capacity in Europe declined by 60 percent to 7.5 billion euros ($9.3 billion) last year, the first annual fall since 2012.

“There is definitely competition. The larger the project, the larger the investors which look at them,” said Oldrik Verloop, head of client advisory services for real assets at Aquila Capital, which manages 3.6 billion euros of renewable assets.

MEGATURBINES  :o
The wind sector is undergoing structural change that is altering the calculus for investors.

While returns on offer beat interest rates by a wide margin, they are still lower than the double-digit percentage returns projects yielded before governments across Europe started to cut the generous subsidies that have cradled the wind power sector since its inception in the early 1990s.

Last year, auction systems were introduced which involved lower government handouts and drove down margins for projects.

The reason investment funds remain interested lies in the long-term revenues and stable cash flows wind farms generate, much like other infrastructure projects, plus the fact that technological advances are bringing down costs.

In the last decade, turbines have grown larger, with some now standing taller than the giant London Eye Ferris wheel which graces the skyline of the British capital – and even larger “megaturbines” are in the works. Bigger turbines sweep a larger area and harness more wind, cutting costs per megawatt.

Vortex Generators 🌟 on a wind turbine


VGs Increase ⚡ AEP up to 3% ✨


Quote

EDF Renewable Services and 3M are providing owners the opportunity to increase AEP by installing maximum performing, highly reliable and quick-to-install 3M™ Wind Vortex Generators.

Vortex generator installation is tailored to each specific blade type and operating environment, improving blade performance by energizing the flow around the surface. This reduces flow separation and increases the performance of the entire turbine in terms of power, load and service life.

Vortex generators can increase AEP up to 3% and installation can pay for itself in about 1-2 years!
