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

GREG ALVAREZ MAY 25, 2017

“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.

http://www.awea.org/1Q2017MarketReportRelease

“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.

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.

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

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.

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:

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)
Quote

“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.”

Quote
“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.”

Quote
“Mechanic inspecting the blades of the windmill before fitting on the rotor to ensure perfect working of the windmill.”

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.”

Check out this video for more information about how wind keeps the lights on for American families and businesses:

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.

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

June 27th, 2017 by Joshua S Hill

SNIPPET:

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.”

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

https://www.ecowatch.com/worlds-largest-wind-turbine-2449212399.html

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
Quote
"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!
