Explore every American wind farm and wind factory on our new interactive map


by Hannah Hunt

Our first-ever American Wind Week is in full swing, delivering exciting updates on the falling costs of wind, progress in the offshore wind market, and overwhelming public support for wind across the country.

But we’re not stopping there.

Today we’ve released a new interactive map that allows anyone to easily view the location of every utility-scale wind project and wind-related manufacturing facility in the United States, visualizing the growth of America’s largest source of renewable energy capacity over time.

Why did we build this map? We know that wind power is providing economic benefits to all 50 states, creating jobs and deploying wind projects in rural communities each year. This map helps to visualize, for the first time, the footprint of the U.S. wind industry, and in more detail than ever before.

The default map view shows all online utility-scale wind projects. However, there’s also a time-lapse feature built in to show the progress of wind power capacity built over time. The time-lapse feature begins in 1981, when the first modern projects were built in California. It then continues through 2017, where wind project development is now strongest in heartland states like Texas, Iowa, Oklahoma, and Kansas.

Beyond the time lapse, users can zoom in and click on individual symbols to find more details about each online wind project, including the name of the project, when it came online, the size of the project, the number of wind turbines, and its congressional district.

The map also includes the locations of the more than 500 active U.S. wind-related manufacturing facilities. When users click on each factory, they’ll discover the name of the company and the type of wind component they produce.

AWEA’s new map uses only a small percentage of the full wind project and manufacturing data available to AWEA members through Market Database Pro, a comprehensive, interactive database of all online, under construction, and advanced development wind projects, and all active wind-related manufacturing facilities. Over 50 data points are provided at both the project and turbine level, with advanced interactive mapping services including filtered search capabilities, summary maps, and political boundaries.

Click on the map to access our new interactive tool (at link below).

The wind industry currently supports over 100,000 U.S. jobs across all 50 states, with nearly 85,000 MW of installed capacity at the end of the second quarter of 2017. That’s enough to power 25 million American homes. Take time to explore our new map to discover where these economic benefits are being delivered.

National lab: Wind power has become historically low-cost

August 8, 2017

by Hannah Hunt: Senior Research Analyst with AWEA focused on wind industry data and analysis, with applied GIS experience.

Talk about good timing: Building on our first-ever American Wind Week, the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (LBNL) released its annual Wind Technologies Market Report today.

LBNL’s findings confirm that U.S. wind energy costs continue to fall, technology continues to advance and performance continues to improve. This has helped the wind industry sell energy at historically low prices to electricity customers, increasing demand from utilities and corporate purchasers alike. As a result, the outlook for the industry is strong.

All of this activity drives job creation– new wind jobs are up 32 percent since 2015 and now top 100,000.

Let’s look at the report’s highlights:

Wind energy has become historically cheap

LBNL examined wind power purchase agreement (PPA) prices across the country, finding that the average levelized PPA price fell to about $20/megawatt hour (MWh) last year. That is a 66 percent price reduction since 2009. PPA prices have fallen across the country, varying by region, with the lowest prices found in the interior.

The low prices reported by LBNL confirm similar recent reports. For example, late last year Wall Street management firm Lazard reported a two-thirds reduction in the unsubsidized levelized cost of energy (LCOE) for wind since 2009.

As those other analysts have noted, wind energy is now the lowest-cost option among all energy sources. PPAs not only provide cost-competitive pricing today, they also allow utilities and corporate purchasers to secure price stability over periods of 10, 20, or even 30 years, providing a hedge against future fuel price increases.

It has gotten much cheaper to build new wind turbines

LBNL reported that it now costs 33 percent less, on average, to install a new wind turbine than the peak reported in 2009 and 2010. Similar to PPA price data, installed costs were lowest in the interior states. Installed costs include all expenses before a wind project comes online, including turbine purchases, balance of plant, and interconnection costs. As turbine purchases are considered the most expensive component of a wind project’s installed costs, decreases in turbine prices were cited by LBNL as the primary factor in cost decreases.

Technology advancements increased wind project performance

Cost reductions continued in 2016 even as wind turbines grew larger, which is a remarkable accomplishment. For turbines installed in 2016, LBNL reported a 13 percent increase in average rotor diameter length over the previous 5-year average, as well as an 11 percent increase in average rated turbine capacity. These technology improvements enable wind turbines to optimize their performance and produce more electricity by reaching stronger, steadier winds. Increased rotor diameters in particular helped to boost new wind turbine performance, with wind projects built in 2014 and 2015 reporting a 42.5 percent average capacity factor in 2016, compared to a 32.1 percent capacity factor for projects built between 2004-2011.

A new finding from the report also reveals how increased performance is being pursued through site customization. That means different turbine models throughout the same wind farm are used to ensure projects reach peak performance. Nearly 25 percent of all wind projects installed in 2016 used multiple turbine configurations from the same turbine manufacturer.

The report supports AWEA data that wind power is now the leading source of renewable energy capacity in the country

The wind industry deployed 8,203 megawatts (MW) in 2016, for a total of 82,143 MW of installed capacity at the end of the year—enough to power 25 million average American homes. That strong installation activity pushed wind power past conventional hydropower to become the largest renewable energy capacity source in America. AWEA’s 2017 second quarter market report confirms strong continued activity, with new wind farm development up 40 percent over this time last year.

The outlook for the wind industry is strong

While the LBNL report notes strong growth is expected to continue through 2020, the report does conclude with a balanced discussion of factors affecting the outlook for the U.S. wind industry in the 2020s.

It lists many positive factors, including “the potential for continued technological advancements and cost reductions enhance the prospects for longer-term growth, as does burgeoning corporate demand for wind energy and continued state (renewable portfolio standard) requirements. Moreover, new transmission in some regions is expected to open up high-quality wind resources to development.”

Some have focused on the report’s discussion of potential economic challenges for the industry, including competition from natural gas and solar. However, it should be noted that those challenges are nothing new and have in fact been listed in every version of the report this decade. Thanks to the innovation and productivity of American workers, the wind industry has been able overcome those challenges by greatly exceeding cost reduction expectations, and we expect that successful track record to continue.

LBNL’s full report provides valuable insights on wind industry market and technology trends. We’re excited to see that wind energy is more cost-competitive than ever, with momentum in place to supply 10 percent of the country’s electricity by 2020, while adding another 50,000 jobs to our 100,000-strong wind energy workforce over the same time frame.

Utilities Shifting Away from Wind, Solar PPAs

August 8, 2017

By Chris Martin, Jim Polson and Mark Chediak, Bloomberg

There’s a new model emerging for growth-starved utilities looking to profit from America’s solar and wind power boom.

American Electric Power Co. is using it for a $4.5 billion deal that’ll land the U.S. utility owner a massive wind farm in Oklahoma and a high-voltage transmission line to deliver the power. NextEra Energy Inc.’s Florida unit is using it to build solar farms. And in April, the chief executive officer of Xcel Energy Inc. said he’d use it to help add 3.4 GW of new wind energy over the next five years.

Here’s how it works: Some utilities that for years contracted to buy electricity from wind and solar farm owners are now shifting away from these so-called power purchase agreements, or PPAs. They’re instead seeking approval from state regulators to buy the assets outright and recover the costs from customers through rates. While the takeovers are being branded as a cheaper way of securing power, saving ratepayers millions in the end, they also guarantee profits for utilities.

“We keep wondering why utilities are always signing PPAs that pass the cost through to customers,” said Amy Grace, an analyst at Bloomberg New Energy Finance. “If you put it in your rate base, you can get a guaranteed return on it. There’s a big upside to ownership.”
With the cost of building solar and wind farms sliding and electricity demand weakening, owning renewables is a more attractive proposition than ever for utilities.

The price of wind has come down enough that it’s going to be competitive with anything else  ;D you’re probably going to propose to build out there,”
Kit Konolige, a New York-based utility analyst for Bloomberg Intelligence, said by phone Wednesday.

Biggest Hurdle

The catch, of course, is regulatory buy-in. AEP will need approval from Arkansas, Louisiana, Oklahoma, Texas and federal regulators to purchase the 2,000-MW Wind Catcher farm from developer Invenergy LLC, build a 350-mile (563-kilometer) transmission line and bake the costs into customer rates. The planned to file these plans with regulators on July 31.

American Electric wants regulatory approvals by April, Chief Executive Officer Nicholas Akins said on the company’s second-quarter earnings call Thursday. Central to the project are $2.7 billion of U.S. tax credits for wind production. No rate increase will be needed, he said.

Floating Turbines  for Hywind Scotland Offshore Wind Farm in Transit

July 20, 2017

By Renewable Energy World Editors
 offshore wind

Five floating turbines for the Hywind offshore wind farm this week began their journey from Stord, Norway, to Buchan Deep, 25 km east of Peterhead in Scotland, according to Abu Dhabi-based Masdar, a co-owner of the project.

The 6-MW turbines, which are placed on top of ballasted steel cylinders, were assembled outside Stord this summer and now are being individually towed to Scottish waters, the company said. Each turbine’s journey takes four days of sailing across the North Sea. Final installation procedures will take two to three days per turbine, with installation scheduled to be finished by the end of August. 

In addition, the loadout of the cables for the project will begin in Halden, Norway, the company said. An installation vessel will go to Kristiansand, Norway, to pick up vertical anchors and buoyancy modules before heading to Peterhead for pull-in of the export cable. The cable will then be laid out in Buchan Deep with the second end connected to one of the floating wind turbines. After installing the export cable, the remaining four infield cables will be installed by the end of September.

Earlier this year, Masdar acquired a stake in the Hywind project, which is majority owned by Statoil :o  ;D.

Agelbert NOTE: It's nice to see that a Fossil Fuel Corporation (i.e. Statoil, NOT the U.S. Big Oil IDIOTS) can see the Renewable Energy writing on the wall and has begun the transition.  ;D May any Fossil Fuel Corporation that doesn't transition away from fossil fuels to Clean Energy GO BANKRUPT SOON!

First US Offshore Wind Installation Vessel to be Built with Oil and Gas Expertise  :o  ;D

Expected delivery of the Jone-Act-compliant vessel is late 2018.

June 30, 2017

By Jennifer Runyon Chief Editor


The vessel will be based on a US-built barge. Zentech plans to install four truss legs with spud cans, a proven oil and gas design, and integrate them into a newly built hull.

In late 2016, the first U.S. offshore wind farm was commissioned off the coast of Rhode Island. In constructing the Block Island Wind Farm, developer Deepwater Wind had to use a wind turbine installation vessel —Fred Olsen Windcarrier’s Brave Tern — from Europe because no boat big enough to install the vessels existed yet in the United States. Because of U.S. regulations in the Jones Act, Brave Tern was not permitted to touch the shore , meaning that other U.S.-flagged vessels had to transport equipment from the U.S. coast to the installation site, adding additional cost to the installation of the project.  >:(

The Zentech and RRI vessel will solve that logistical headache. The company said that the vessel will also act as an oil and gas crane jack-up for decommissioning in 300-ft water depths when not in service for installing and/or maintaining wind turbines.

Design of the Jones Act vessel should allow it to navigate the New Bedford Hurricane Barrier, the company said. It will be able to carry and install components for at least three complete turbines, up to 9-MW capacity  , according to the company. The vessel’s jacking system will be rated at a capacity of 16,000 tons, extending the unit’s service life.

The company said that the vessel may one day be able to install four 8-MW fully assembled wind turbines and will be ready for anticipated 10-MW capacity machines in the future.

“With larger scale offshore wind projects following Block Island, the U.S. market requires forward-looking marine logistics,” said Andy Geissbuehler, Managing Partner of Renewable Resource International.

World's Largest Wind Turbine Will Be Taller Than Empire State Building 


Agelbert NOTE: Unlike onshore wind turbines, Offshore wind turbines are not limited in size and diameter by highway overpass heights and highway widths. So, these new giants will be far more efficient, AND RELIABLE, than any fossil fuel or nuclear power plant that has EVER been built. Therefore, expect Trump and friends to go to great lengths to keep these Renewable Energy Marvels from going up in our oceans and the great lakes. The Fossil Fuelers have NEVER been about a level ERoEI (energy return on energy invested) playing field. And as to the claim of these crooks and liars that they provided, and still provide, a polluting product because we-the-people "wanted" them to, as government subisies of polluting fuels for a century attest, just throw the following quote at them: ;D
"There is a nice legal concept called estoppel. If you argue that you didn't kill the Major in the library with the Ming vase because you were in bed with his wife, you are estopped from pleading self-defence. In the same way, polluters are estopped from arguing that they were only complying with public policy as laid down in the law, because they spent tens of millions shaping those policies and laws to their advantage." James Wimberley

The fossil fuel industry is hell bent to trash the beauty and life that is left on our biosphere. Don't let them get away with it!

Onshore Wind Generates Nearly A Quarter Of Northern Ireland’s Electricity

June 27th, 2017 by Joshua S Hill


While obviously, Northern Ireland is a smaller country — it is only 17% the size of Scotland, for example — the UK as a whole only sources 6% of its electricity from onshore wind, so Northern Ireland is definitely doing well. 

“Crossing this 1 GW threshold shows just how much of a success story onshore wind is in Northern Ireland,” explained Rachel Anderson, Chair of NIRIG. “Onshore wind remains one of the vital growth areas to our modern low-carbon economy, so we need to ensure that politicians here join us in securing a bright future for this technology.” 

Renewable electricity is making a massive contribution to Northern Ireland, creating jobs, bringing inward investment and enabling local regeneration,” added RenewableUK’s Executive Director, Emma Pinchbeck. “Northern Ireland is making the most of its great onshore wind resources, embracing a mature technology which is now the cheapest way to generate electricity bar none, helping to keep consumers’ bills down.”

Record one-year capacity increase in India

7 April 2017 by Suuhas Tenddulkar,
 financial year, finishing on 31 March 2017, according to the ministry of renewable energy.

INDIA: A total of 5,400MW of new wind capacity was installed in India over the last financial year, finishing on 31 March 2017, according to the ministry of renewable energy.

It beat the country’s previous one-year record of 3,423MW, set in 2015-16, by over 57%. Cumulative capacity across India now stands at 31,117MW.

Nearly two-fifths of the year’s new capacity was added in March alone as developers rushed to avail themselves of the generation-based incentive (GBI) benefits, which were in force until the end of the month.

Andhra Pradesh, a relatively late entrant to wind power, installed 2,190MW, followed by Gujurat with 1,275MW, and Karnataka with 882MW.

Other states adding wind power were: Madhya Pradesh (357MW), Rajasthan (288MW), Tamil Nadu (262MW), Maharashtra (118MW), Telangana (23MW), and Kerala (8MW).

Despite the expiry of the GBI scheme, installations for the current financial year are expected to exceed 5GW, considering the size of the pipeline and the additional 1GW of capacity that was awarded through auctions in March.

Another encouraging sign for wind development in India is that states such as Jammu and Kashmir, and Himachal Pradesh have taken concrete steps to set-up their first projects.

New report: Adding renewables keeps the lights on and money in America’s pockets 

Yesterday, a new report from Analysis Group reconfirmed an important point: adding renewable energy to America’s electricity grid strengthens reliability and saves consumers money.

AWEA CEO Tom Kiernan penned a column in the Huffington Post explaining some of Analysis Group’s findings. Here are a few highlights:

Although some commentators have raised concerns that the declining financial viability of certain conventional power plant technologies…may be jeopardizing electric system reliability, there is no evidence supporting that conclusion.

Many advanced energy technologies can and do provide reliability benefits by increasing the diversity of the system. The addition of newer, more technologically advanced and more efficient natural gas and renewable technologies is rendering the power systems in this country more, rather than less, diverse.

“By replacing a portion of the higher-cost fuel we used to burn in our plants, we have been able to add renewables and invest in making the power grid even more reliable, all while keeping electricity affordable,” said Ben Fowke, CEO of Xcel Energy, in the past week.

Why does adding wind and solar make the system more reliable? They’re now widespread, they change slowly and predictably, they can be flexibly managed, and a diverse system is the most reliable system. That way, if one generation source fails, others can pick up the slack.

In February 2011, when many coal plants broke down due to extreme cold, wind output remained high throughout that event, earning accolades from the grid operator for helping to keep the lights on. Because all energy sources, whether coal, natural gas, wind, or nuclear, are subject to interruptions, diversity makes the power system reliable.

Fundamental market forces – the addition of highly efficient new gas-fired resources, low natural gas prices, and flat demand for electricity – are primarily responsible for altering the profitability of many older merchant generating assets in the parts of the country.

A simple glance at where coal and nuclear plants are being retired offers evidence: It’s mostly in the Northeast and Southeast, areas with comparatively few wind turbines. Meanwhile, there have been few coal and nuclear retirements across the Wind Belt, where states like Iowa, Oklahoma, Kansas and the Dakotas are all now generating more than 20 percent of their electricity using wind.

Analysis Group researchers find “the ongoing diversification of generation supply has lowered wholesale electricity costs in most parts of the U.S. and has contributed to recent declines in consumers’ overall cost of living.”

Global Wind Day 2017: Photo contest winners       

In celebration of Global Wind Day, the Global Wind Energy Council announced the winners of its photo contest earlier today. The winners took some seriously impressive shots.

Here are the photos that came out on top, along with a description of their subjects: (at article link)

“A unique, first of its kind 73.2 MW wind farm on a small and uninhabited Greek island called Agios Georgios. Agios Georgios is the only onshore wind farm with offshore characteristics to be ever built across the globe. 25 nautical miles of submarine cables were needed in order to connect the wind park to Athens’ electrical grid. In the middle of the vast Aegean Sea, Agios Georgios wind farm produces clean energy for the increasingly demanding Attica region.”

“October 1, 2016- 15 foot waves, during a squall, are dwarfed by 600 ft. (180m) turbines at the first commercial offshore wind farm in the United States, located 3.8 miles from Block Island, Rhode Island in the Atlantic Ocean. Five Halide 6MW turbines, installed by Deepwater Wind (were currently under commissioning) are now producing 30 MWs of power and is the pilot project for the development of an offshore wind potential of 10,800 gigawatts (GW) in the United States.”

New York takes a big first step toward 50 percent renewable energy

NEWS JUNE 2, 2017

As one of the country’s largest economies and most populous states, it was a big deal when New York state passed a 50 percent by 2030 clean energy standard last year.

Today, the Empire State took the first meaningful steps toward meeting that goal: it announced a renewable energy solicitation aimed at making progress on the 50 percent target.

Under the solicitation, the New York State Energy Research and Development Authority and the New York Power Authority will purchase enough renewable energy credits for 2.5 million megawatt hours of electricity—the state’s largest renewable solicitation to date and enough to power 230,000 homes a year.

“Clearly Governor Cuomo is serious about bringing investment in clean energy to New York State, and creating new jobs in wind and solar power,” said Anne Reynold, Executive Director of the Alliance for Clean Energy New York. “This is the kind of action that will get new wind turbines spinning and new grid-scale solar projects generating clean power across the state in the coming years.”

And these new projects will create jobs and spur economic development in communities across the state. Here’s a look at the types of benefits wind has already brought to towns throughout New York:

GE Floating $1.7 Billion Platform in Germany Shows Power of Wind

June 2, 2017 by Bloomberg

The platform is a key part of the DolWin3 offshore project and will help transmit wind power generated in the North Sea. Photo: TenneT TSO (at article link)

By Brian Parkin (Bloomberg) — General Electric Co. said it’s ready to ship a 1.5 billion euro ($1.7 billion) offshore wind platform destined for the North Sea, underscoring the industrial giant’s commitment to clean power.

DolWin3 offshore project

The platform is a key part of the DolWin3 offshore project and will help transmit wind power generated in the North Sea, according to Alf Henryk Wulf, who heads GE’s power unit in Germany, which led construction of the unit. Wulf didn’t want to discuss U.S. President Donald Trump’s decision   to quit the Paris accord during an interview at a port in Rostock, Germany where the 900-megawatt high-voltage converter was built.

Commissioned by grid builder Tennet Holding BV, Dolwin3 is undergoing final dry-dock tests before being floated around Denmark and into the North Sea.The platform will bundle power from three wind farms next year, transmitting high-voltage direct current onshore, where it can then be reconverted to alternating currents for use in homes.

“As offshore prices fall, the North Sea’s potential for offshore is shining even brighter ,” Wulf said. “We all owe it to consumers to engage that potential.”

GE is competing to design and construct another 900 megawatt connector for Tennet in the German North Sea called Dolwin6, Wulf said. That platform is due to go into operation in 2023. GE has built about 10 converter platforms in the North Sea and Baltic, competing with companies including Siemens AG.

Trump’s decision to pull the plug on the Paris treaty places GE at odds with his administration. Chief executives from some of the U.S.’ biggest companies implored the president not to remain in the Paris accord before Trump took his decision.

“Disappointed with today’s decision on the Paris Agreement,” GE Chief Executive Officer Jeff Immelt wrote via Twitter. “Climate change is real. Industry must now lead and not depend on government.”

Wulf stressed that GE and Siemens are well placed to harness the offshore boom , where driving down costs are the key to profitability, because they are the only two companies that make converter platforms and turbines.

Germany, which holds the rotating presidency of the Group of Twenty nations, has sought to keep the U.S. on board the Paris treaty, wooing Trump with projections that a global shift from fossil fuel would create jobs and stimulate economic growth.

Just 1 percent of the North Sea’s offshore potential has been exploited, and billions of euros in future investment will be needed to tap the rest, Siemens said last month. Dong Energy SA and Energie Baden-Wuerrtemberg AG won Germany’s maiden auction of 1.49 gigawatts of offshore power in April offering to build parks free of subsidies.

Germany set a target of 6.5 gigawatts of offshore capacity by 2020 and 15 gigawatts by 2030, up from 4.1 gigawatts installed last year.

Reaching New Heights - Wind Power  :o

Published on May 23, 2016

Reaching new heights with the construction of the Siemens concrete wind turbine tower technology.

Agelbert NOTE: Please spare me any wailing and moaning about fossil fuels used to make concrete and trucks and cranes that run on fossil fuels. Those Washington Monument high towers will last AT LEAST as long as the Washington monument itself. It's a ONE SHOT deal and then the Renewable Energy harvest just goes on and on.  The high towers are part of the TRANSITION to 100% Renewable Energy, whether you fossil fuelers like it or not!   :D

Bringing the birthplace of wind power into the 21st century

JUNE 2, 2017

I remember when my dad got his first “car phone.” It was bulky, required an antenna on the window and only worked once in a while. The iPhones we carry in our pockets today, made with three decades of product development, seem otherworldly by comparison.

There’s a similar technology comparison playing out across California.

American wind power was born in the Golden State, where the first large-scale wind farms were built in the 1980’s. Many still generate electricity today, more than 30 years later. But through a process known as repowering, companies are starting to replace vintage turbines with modern equipment.

The transition is akin to moving from a “car phone” to an iPhone.

NextEra Energy and Sonoma Clean Power just broke ground on a full repowering at the Golden Hills North wind farm, replacing 283 turbines from the 80’s with just 20 modern ones capable of generating significantly more electricity.

“[This] allows us to breathe new life into an old project, reduce the impact on the environment, and provide good jobs and meaningful economic benefits for the local economy,” said Daryl Hart, director of development for NextEra Energy Resources.

ther companies are repowering old California projects too. EDF Renewable Energy recently upgraded the Shiloh IV wind farm, originally built in 1989. Just 50 new turbines replaced 235 old machines while quadrupling the project’s capacity to generate electricity.

Elsewhere in California, 21 modern turbines replaced 145 vintage machines at the San Gorgonio project in Riverside County in 2015.

American innovation is on full display at these projects. Decades ago, wind power pioneers figured out a way to generate electricity out of thin air. Through research, entrepreneurship and hard work, today’s turbines are more cost-effective, more reliable, and generate vastly more electricity— 22 times more electricity than an average turbine installed in 1990.

Keep track of all of the latest repowering news in our Quarterly Market Reports.

Grid reliability, security and diversity: Another way wind works for America


“What happens when the wind doesn’t blow or the sun doesn’t shine?”

That’s a common question from those wanting to understand how grid operators integrate renewable energy.

Fortunately, the experts who keep the lights on every day find they can reliably handle large amounts of wind and solar energy.

Grid operators have always balanced major shifts in supply and demand. Factories, air conditioners and appliances turn on and off in waves, varying by time of day and season. Major spikes occur from events as simple as halftime during a football game, when millions of refrigerator doors open.

Large coal, gas, and nuclear power plants can also break down unexpectedly, suddenly removing significant amounts of electricity from the system.

Meanwhile, spread across 41 states, the output of America’s 53,000 utility-scale wind turbines stays relatively constant. Changes are slow and predictable based on weather forecasting, and are mostly canceled out by far greater variations in demand and other supply.

It’s generally more expensive for grid operators to accommodate the abrupt loss of a large conventional generator, because that requires keeping fast-acting backup resources “spinning” 24/7.

A prime example occurred during 2014’s Polar Vortex weather event. The bitter cold and loss of gas supply forced many conventional power plants to shut down abruptly. At the same time, high demand for home heating sent natural gas prices and electricity prices skyrocketing. However, wind turbines kept reliably generating electricity, saving Great Lakes and Mid-Atlantic consumers over $1 billion in two days.

The U.S. has enough installed wind power to supply the equivalent of 25 million homes. So utilities and grid operators have already had ample opportunity to figure out how to integrate wind energy.

Xcel Energy’s Colorado Balancing Authority already runs on 20 percent renewable energy. ERCOT in Texas got 15 percent of its electricity from wind in 2016. The Southwest Power Pool (SPP), grid manager across parts of 14 states, is nearing 20 percent wind year-round — and just peaked at 54 percent wind earlier this year. PJM, the country’s largest grid operator, recently found it could handle over 75 percent wind power reliably.


“Ten years ago we thought hitting even a 25 percent wind-penetration level would be extremely challenging, and any more than that would pose serious threats to reliability,” said Bruce Rew, SPP’s vice president of operations. “Now we have the ability to reliably manage greater than 50 percent. It’s not even our ceiling.”

Wind power remains on track to supply 10 percent of U.S. electricity by 2020, adding diversity, security and reliability to our electric grid. The men and women keeping our lights on already know wind works, and by helping ensure the country’s grid stays secure, wind works for all Americans.

First quarter highlights: We’re about to build a Texas-sized amount of wind power

Greg Alvarez 
May 23, 2017 This column originally appeared in the WINDPOWER show daily.

American wind power is in the midst of a Texas-sized boom to start 2017. The industry just posted its best first quarter in eight years, and put up a new turbine every two hours and 24 minutes over the year’s first three months.

So what top trends are emerging?

Strongest first quarter since 2009

During the year’s first three months, 2,000 megawatts (MW) of new capacity came online, more than the first three quarters of 2016 combined. The U.S. now has enough installed wind capacity to power 25 million American homes.

U.S. workers built 908 turbines during the first quarter, and that means a lot of business. Each turbine supports 44 years of full-time employment over its lifespan, so American wind power just supported nearly 40,000 years of full-time employment.

We’re about to build a Texas-sized amount of new wind power

Nearly 21,000 MW of new wind capacity is currently under construction or in advanced development, about the same amount online in Texas today.

As the country’s wind leader, Texas already has enough installed wind capacity to power over five million American homes, and wind jobs in the state top 22,000.

So the amount of new wind in the pipeline is a big deal.   

North Carolina joins the party

North Carolina became the 41st state with a utility-scale wind project when Avangrid Renewables’ Amazon Wind Farm US East started generating electricity earlier this year. The project was the first built in the Southeast in 12 years, and offers clear evidence that improved turbine technology can help bring low-cost wind energy to more parts of the U.S.

Texas stays at the head of the pack

Although wind power grew from coast-to-coast during the first quarter, Texas kept its tight grip on the leader spot with 724 MW coming online.

The corporate buyer trend continued facing front and center in the Lone Star State too, with Home Depot buying enough output from a Texas wind farm to power 100 stores. Other deals included names like 7/11, T-Mobile and Facebook.

Kansas finished behind only Texas in new wind installations during the quarter. Nearly 500 MW of new in-state capacity came online, and the state will soon top 5,000 MW.

Grid operators continue to reliably integrate more wind power
The Southwest Power Pool (SPP), grid operator for 14 states across the Midwest, set a new high water mark by surpassing 50 percent wind penetration.  :o

SPP’s new record offers further proof that wind power helps keep the lights on for America’s families and businesses.

Growth is expected to remain strong in the months and years ahead— according to the U.S. Department of Energy 10 percent of U.S. electricity could come from wind by 2020.


Agelbert NOTE: More wind power means LESS USE of WATER! This means more resilience for communities when drought conditions are present. Water needs to be available for people, animals and plants instead of being squandered by thermal power plants.

This is just one more reason (among MANY reasons) why fossil fuel powered thermal power plants are TOO ENVIRONMENTALLY & MONETARILY COSTLY for ANY of the above mentioned states.

Scottish Offshore Wind May Get $13BN Lift From Bird Ruling 

May 17, 2017

By Jess Shankleman, Bloomberg 
Scottish judges paved the way for as much as 10 billion pounds (US$13 billion) to be invested in offshore wind power by overturning a ruling that said projects may kill too many birds.

Planning permission should move forward at four wind farms being developed by SSE Plc, Mainstream Renewable Power Ltd., Fluor Corp. and SDIC Power Holdings Co., according to the ruling by three judges at the Inner House at the Court of Session in Edinburgh on Tuesday.

They said a judge in the Outer Court was wrong to revoke consent in July for the wind farms, that may create as much as 2.3 GW of new capacity off Scotland’s east coast. The earlier ruling asserted that Scottish ministers didn’t properly assess how the projects would threaten migratory seabirds, such as the puffin.

The earlier decision “strayed well beyond the limits of testing the legality of the process,” according to the ruling." “Matters of scientific fact and methodology which, whatever the judge’s own particular skills may be, are not within the proper province of a court of review.”

Scotland’s government welcomed the decision by saying it “remains strongly committed to the development of offshore wind energy,”    according to an email from Minister for Business, Innovation and Energy Paul Wheelhouse. Offshore wind “has a key role to play in our fight against the threat posed by climate change to both our society and our natural environment,” he said.

Mainstream said it would now seek to develop the 2 billion pound Neart Na Goithe offshore wind farm as quickly as possible, according to a separate statement. The project has a contract with the U.K. government for a subsidy of 114 pounds/MWh.

The Royal Society for the Protection of Birds, which brought the original case against the wind farms, said the projects could be among the deadliest wind farms for birds anywhere in the world.

“RSPB Scotland is, of course, hugely disappointed by today’s Inner House judgment,” said Stuart Housden, director RSPB Scotland, in an email. “Combined, these four huge projects threaten to kill thousands of Scotland’s internationally protected seabirds every year, including thousands of puffins, gannets and kittiwakes.”

The decision will boost investor confidence in the U.K.’s emerging offshore wind industry, as the country hosts its latest subsidy auction, said Tom Harries, Bloomberg New Energy Finance analyst. “Developing an offshore wind site in the U.K. is risky and costly enough already, without the added threat of retroactively losing an environmental permit.”

Edward Black, a spokesman for SSE, said the company was “delighted” with the outcome of the appeal and will now consider the best options for the two Seagreen wind farms affected.

REPORT: Part 1: Limits to Scale in Wind

May 8th, 2017 by John Farrell  

Full report available at the Institute for Local Self-Reliance:  https://ilsr.org


For nearly a century, it’s been considered conventional wisdom that larger-scale power generation means lower-cost electricity. This wisdom is built on two basic theories of economies of scale.

Below is part one of our Is Bigger Best Report, a report released in September 2016. Conventional wisdom suggests the biggest wind and solar power plants will be cheapest, but where they deliver power, and who will own them, matters more. Be sure to read parts two and three in the next week.

First, there’s the simple fact that larger volume components of power plants provide more usable space than the related materials costs. This simple illustration explains. The box on the left has a volume of 1x1x1 = 1 cubic foot. To assemble the box, you need 6 square pieces of material, each with an area of 1, for a total of 6 square feet. The box on the right has a volume of 2x2x2 = 8 cubic feet. The larger box can be assembled of 6 square pieces, each with an area of 2×2 = 4 square feet, for a total of 24 square feet. We’ve increased the volume of our container 8-fold, with only a 4-fold increase in material costs.

As power plants became bigger in the first half of the 20th century, they captured this economy of scale in materials.

The second basic theory is that the average cost of a product decreases the more you make of it. This takes into account the scale economies in material costs (in building the factories), but also the notion that some overhead costs (such as annual registration fees, insurance, etc) are fixed or grow more slowly than the total output of a business.

Both of these theories were well supported by data in the early years of electricity generation in the 1900s, with coal, oil, and then nuclear power plants producing lower cost power from larger sized plants. The advantage to size also lent credence to the conventional wisdom of monopoly utilities. Big power plants required large amounts of capital, and capital markets offered lower interest rates to companies that did not have the risk of competition for their ever­-larger power plants.

But after decades of success, the “bigger-is­-better” mantra stopped generating returns on investment, nearly 50 years ago. In super­-large fossil fuel power plants, specialized equipment required excessively high temperatures and special materials that were more expensive than the marginal gains in efficiency. This graphic, from a book called Power Loss, illustrates the plateauing of power plant efficiency in the mid­-1960s, as challenges in operating giant power plants offset their economies of scale.

The plateau in plant efficiency from technical challenges was accompanied by a leveling off in the cost reductions of building bigger. Bigger power plants, evidence suggested, incurred higher indirect costs, such as much longer construction time. In the 1970s in particular, high inflation and other factors made up as much as 60% of a power plant’s cost, and made delay costly.

Despite the evidence about limits to scale economies, the conventional wisdom that bigger is better has persisted into the renewable energy power industry. It’s particularly ironic, since the costly ever­-bigger power plants of the 1970s led Congress to pass the 1978 Public Utility Regulatory Policies Act (PURPA), the federal law that opened the door to renewable energy alternatives to conventional power plants. This lesson seems lost on many observers of the renewable energy industry.

Renewable Energy Economies of Scale

The economies of scale of renewable energy take three forms, slightly different than those for fossil fuels:

1.The first is similar, that larger solar or wind power plants will produce less costly power than smaller ones, given a similar level of sunshine or wind.

2.The second suggests that renewable electricity is best produced in areas of the highest resource quality, and then transmitted long-distance to users.

3.The third is an assertion that the road to the most renewable energy the most quickly is via the largest power plants.

Full article with several eye opening charts and explanatory graphics:  


John Farrell is the Director of Democratic Energy at the Institute for Local Self-Reliance and widely known as the guru of distributed energy.

John is best known for his vivid illustrations of the economic and environmental benefits of local ownership of decentralized renewable energy.

He’s the author of Energy Self-Reliant States, a state-by-state atlas of renewable energy potential highlighted in the New York Times,  showing that most states don’t need to look outside their borders to meet their electricity needs.  He’s also written extensively on the economic advantages of Democratizing the Electricity System, published a rich interactive map on solar grid parity, and polished the policies (like Minnesota’s solar energy standard) necessary to support locally owned renewable energy development.


Agelbert NOTE: John makes a valid case for SMALL Renewable Energy projects by showing the increased transmission cost limitations of large Renewable Energy projects. That is, when you are harvesting a huge amount of energy, it has to be sent hither and yon to reach everybody that wants it. Yes, the transmission costs increase with distance. However, that is because the infrastructure for moving massive amounts of energy over high voltage transmission corridors specifically designed to do just that has not been built up yet. They haven't built that greased lightning grid simply because the fossil fuel industry did not need it with their polluting pigs scattered all over the country (the same with nuclear power pigs too!).

But really, even with the present increased costs of sending energy over wires at greater distances, there is NO WAY sending energy in liquid form on gasoline tankers or coal trains is anywhere near as efficient AND cheap as sending energy through wires.

Consequently, both small and large Renewable Energy projects will continue to outcompete polluting fossil fuels and nuclear power even before our advanced national high voltage transmission grid infrastructure is built.

The polluters no longer have absolutely any reason for claiming they have a "competitive" energy product. The only way polluters can "compete" now is by getting Trump to declare the Orwellian Mindfork that "Renewable Energy threatens National polluter profit Security" and making it "illegal" for the grid AND the transportation sector to have more than 50% (or whatever percentage the polluters need to limit clean energy growth) Renewable Energy Penetration.

We need polluters like a dog needs to be covered with ticks slowly killing it. Either we get rid of polluters or perish from pollution.

Jens Stubbe  • 6 hours ago   

The graph over the catastrophic low efficiency in the thermal power plant is really scary. In Denmark the average external efficiency is 45% electric and nearly 40% thermal and the flue gases are cleansed and used or asphalt and cement and a good proportion of the CO2 is used for gypsum production. Even so we out phase coal and will be done by 2023.

As for the size limitations for wind power there is a square cube rule that defines that every time you double capacity you square cube the weight. So far clever engineering has defied this rule. A 9MW nacelle is very close in weight to a 2,3MW nacelle.

The roadmap for continued weight drop looks really good and we could potentially see several times bigger turbines that weigh less than several times smaller simply due to ingenuity.

Currently 17% of the global coal fiber production is consumed by the wind power industry but this is expected to increase to 65% by 2020.

Wind power is already the largest purchaser of several raw materials and is the driving force behind technology development that benefit aerospace, aviation, formula 1, automotive and so on. So apart from being an important contributor to a sustainable future wind power is also cross fertilizing advances in other fields of engineering.

The next big threshold for RE in general and wind power in particular is the P2G cost point. For solar the threshold will demand about 50% cost decrease and for offshore wind about 66%.

Once those thresholds have been met the size of wind power plants and solar power plants will suddenly go up to a level never seen before. Innogy sees Methanol as the energy carrier of the future whereas other sees a plethora of alternative synthetic carriers.

In the North Sea the offshore wind potential is sufficient to power the European continent including electrifying the entire transport sector.

Both MHI Vestas and Siemens Wind power are far advanced with the next generation larger turbines. Siemens Wind power have the capacity to build a 8MW turbine every day and MHI Vestas is catching up rapidly.

At sea the most important gains with scale is the reduced service and maintenance as well as lower cost of installation.

As for the ownership structure we are heading straight towards ever bigger project that leaves no room for smaller projects. Part of this trend is a deliberate strategy where subsidies was only available for large consortia. On the positive side Shell, Statoil and several large utilities are now active in the business.

Wind Industry Just Chalked Up Strongest First Quarter in 8 Years  

America's wind power workforce installed 908 utility-scale turbines in the first quarter of 2017, totaling 2,000 megawatts (MW) of capacity. This is the wind industry's strongest start in eight years, according to a new report released Tuesday by the American Wind Energy Association (AWEA).

"We switched on more megawatts in the first quarter than in the first three quarters of last year combined," said Tom Kiernan, CEO of AWEA, in releasing the U.S. Wind Industry First Quarter 2017 Market Report. "Each new modern wind turbine supports 44 years of full-time employment over its lifespan, so the turbines we installed in just these three months represent nearly 40,000 job years for American workers."

The early burst of activity reflects how 500 factories in America's wind power supply chain and more than 100,000 wind workers are putting stable, multi-year federal policy to work. The industry is now in year three of a five-year phase-down of the Production Tax Credit, and Navigant Consulting recently forecast a strong 2017 for wind power, similar to 2015 and 2016.

New wind turbine installations in the first quarter spanned the U.S. from Rhode Island and North Carolina to Oregon and Hawaii. Great Plains states Texas (724 MW) and Kansas (481 MW) led the pack.

Texas continues as the overall national leader for wind power capacity, with 21,000 MW installed, enough to power more than five million average homes. North Carolina became the 41st state to harness wind power, bringing online the first wind farm to be built in the Southeast in 12 years.

Horace Pritchard, one of nearly 60 landowners associated with the North Carolina project, explained what it means to him and his neighbors: "Farms have been growing corn, soybeans and wheat for a long time here, and the wind farm revenue means a lot of families are protected from pricing swings, floods or droughts going forward. We're just adding another locally-grown crop to our fields, with very little ground taken out of production, and the improved roads really help with access. So it's a great fit here."

Expanding wind farms continue to benefit rural America, since more than 99 percent of wind farms are built in rural communities. According to AWEA's recently released 2016 Annual Market Report, wind now pays more than $245 million per year in land-lease payments to local landowners, many of them farmers and ranchers.

Along with rural benefits, American wind manufacturing facilities remain busy in the first quarter as projects continue to be built. With 4,466 MW in new construction and advanced development announcements recorded in the first quarter, the near-term pipeline has reached 20,977 MW of wind capacity. That's about as much as the entire Texas wind fleet's existing capacity.

Demand remained strong in the first quarter. There were 1,781 MW signed in long-term contracts for wind energy, the most in a first quarter since 2013. Utilities and Fortune 500 brands frequently use these long-term contracts, called Power Purchase Agreements (PPAs), to purchase wind energy. Home Depot and Intuit, maker of TurboTax, both signed up for wind power this quarter, joining a host of Fortune 500 companies like GM, Walmart, and Microsoft that are buying wind energy for its low, stable cost.

In addition to leading brands, low-cost wind power reliably supplies a growing number of cities, universities, and other organizations—including the Department of Defense. This quarter, a Texas wind farm came online to supply a PPA with the U.S. Army. Powering a military facility demonstrates that wind power is ready to reliably serve our most vital electricity needs, boosting American energy security in more ways than one.

Drone Service Provider Secures First License Agreement for Wind Turbine Blade Inspection in Brazil 
May 5, 2017

By Renewable Energy World Editors 

Portugal-based Pro-Drone, S.A., a provider of automated drones for wind turbine blade surveys, recently signed its first licensing agreement with Brazilian wind energy company Arth-Wind to provide inspections of wind blades to the Brazilian market.

“Seeing the Pro-Drone system working at location, blew away all our expectations on the search for a technology that would bring speed, safety and confidence on the information retrieved during a survey of a wind turbine’s blades,” Armando Costa Rego, founder of Arth-Wind, said in a statement.

Pro-Drone said it will provide the required payload and control systems, customized web platform, training and assistance, while Arth-Wind will address the customized reporting commercial development and field surveys to Brazilian customers.

André Moura, founder of Pro-Drone, said that “the Brazilian wind turbine market can now enjoy a fast, reliable and cost-effective process to survey the wind turbine’s blades  ;D, and with the expertise of the Arth-Wind team those surveys will result in better inspection reports, leading to increases in productivity and lower operating costs of wind turbines.”
