Wind Power
By: AGelbert Date: October 11, 2013, 12:23 am
---------------------------------------------------------
A New York Times article dated Nov. 22, 1936, quotes from a
lecture titled “Discoveries and Inventions” Lincoln gave in
1860, before he became president. Here’s the relevant part:
HTML http://www.historyplace.com/lincoln/lincpix/tadbook2.jpg
“Of all the forces of nature, I should think the wind contains
the largest amount of motive power … Take any given space of the
earth’s surface, for instance, Illinois, and all the power
exerted by all the men, beasts, running water and steam over and
upon it shall not equal the 100th part of what is exerted by the
blowing of the wind over and upon the same place.
And yet it has not, so far in the world’s history, become
properly valued as motive power. It is applied extensively and
advantageously to sail vessels in navigation. Add to this a few
windmills and pumps and you have about all. As yet the wind is
an untamed, unharnessed force, and quite possibly one of the
greatest discoveries hereafter to be made will be the taming and
harnessing of it.”

[center]36 V112-3.0 MW turbines ordered for the Crucea North
wind project ;D[/center]
With reference to Vestas Wind Systems A/S company announcement
No. 44 of 10 October 2013, Vestas is pleased to announce a firm
and unconditional order for 108 MW from S.C. Crucea Wind Farm
S.R.L. / STEAG GmbH for the wind power plant Crucea North,
located in the Constanta county in the province of Dobrogea.
The order includes supply, installation and commissioning of the
turbines, along with a VestasOnline® Business SCADA solution as
well as a 10-year full-scope service agreement (AOM 4000).
Delivery is planned to start in April 2014 and commissioning is
expected to be completed by December 2014.
The Crucea North wind power plant is one of the largest in
Romania and represents a step forward in the development of
Vestas’ relationship with one of the key players in wind energy
in Europe.
”The negotiations with Vestas for one of STEAG’s biggest
projects in wind energy have been efficient and focused,” states
Dr. Ralf Gilgen, member of the Board of Management of STEAG
GmbH. “We expect this to be the starting point for a successful
strategic partnership in the development and realisation of
international wind energy projects.”
“We are pleased to receive the Crucea North order from our
valued customer Crucea Wind Farm S.R.L. / STEAG GmbH. This wind
energy project marks another important milestone in further
developing the Romanian wind market, and we are happy to support

experience and efficient wind energy solutions,” says Thomas
Richterich, President of Vestas Central Europe. “With this order
Vestas reinforces its market leading position in the Romanian
market having the strongest local presence and the largest
operational fleet.”
The wind project totalling 108 MW will be a key contributor to
Romania’s ambitious targets as detailed in its National
Renewable Energy Action Plan. The 36 V112.3.0 MW wind turbines
will produce more than 300 GWh per year, which corresponds to an
annual saving of almost 124,000 tons of CO2 emissions.
Furthermore, it will provide enough electricity to cover the
residential electricity consumption of more than 550,000 persons
in Romania.
As of 30 June 2013, Vestas has delivered 654 V112-3.0 MW
turbines worldwide representing a total capacity of more than
1.9 GW, and has received more than 4.5 GW of firm orders for
this model.
About Vestas

The "Windy" City
By: AGelbert Date: October 20, 2013, 7:03 pm
---------------------------------------------------------
I looked up the average wind speed at Chicago (I'm certain it
is much higher a hundred stories up in any of their many
skyscrapers that could easily be fitted with wind turbines).
It turns out that, over a century ago, Chicago earned that
nickname, not because of high wind speeds, but because:
Chicago has been called the “windy” city, the term being used
metaphorically to make out that Chicagoans were braggarts. ;D
While Chicago is widely known as the "Windy City", it is not the
windiest city in the United States: Milton, Massachusetts is.[2]
Chicago is not significantly windier than any other U.S. city.
For example, the average annual wind speed of
Chicago is: 10.3 mph (16.6 km/h);
Milton is: 15.4 mph (24.8 km/h);
Boston: 12.4 mph (20.0 km/h);
New York City, Central Park: 9.3 mph (15.0 km/h); and
Los Angeles: 7.5 mph (12.1 km/h).[3]
HTML http://en.wikipedia.org/wiki/Origin_of_the_name_%22Windy_City%22
Many cities have higher average wind speeds BUT Chicago has
skyscrapers. I have always wondered why they haven't started
putting wind turbines on top of them. Yes, a structural
engineering firm would have to do some beefing up of the
building to handle the extra stresses and load but it would be
worth it. If the average wind speeds are 20 mph or better a
skyscraper height, you have a 24/7 continuous city power source
built in to a metropolitan area (a high energy use area).

[center]Gamesa G97 Model Wind Turbine[/center]
The first offshore wind turbine for wind energy company Gamesa
and for the host-country Spain was inaugurated on Monday, in in
Arinaga Quay (Gran Canary Island). The ceremony was attended by
the President of the Canary Islands regional government, Paulino
Rivero, the Minister for Industry, Energy and Tourism, José
Manuel Soria, and the Chairman of Gamesa, Ignacio Martín.
The 5 MW 154 meter-tall turbine has a rotor diameter of 128
meters, sporting 62.5 meter-long blades, all combining to
produce enough energy to supply 7,500 Canary Island homes with
clean energy.
Gamesa is noticeably excited about their entrance into the
offshore wind market, proclaiming that “Gamesa’s platform is set
to become a benchmark in the sector thanks to the low cost of
energy it offers customers.”
They were equally proud of the fact that the turbine parts were
all made in Spain, noting however that “teams from all over the
world participated in the product’s design and development
phases”, including:
•The blades, each of which measures 62.5m long and weighs 15
tonnes, making them the longest ever produced and transported in
Spain and among the longest in Europe, were made at the factory
in Aoiz (Navarre)
•The nacelle, which measures over 12.5m long, 4m tall and 4m
wide and weighs 72 tonnes, was made in Tauste (Zaragoza)
•The tower, which stretches nearly 90m high, was made by Windar
(a joint venture between Gamesa and Daniel Alonso)
•The electric parts were made in Lerma (power train), Benissano
(electric control cabinets), Coslada (converters) and Reinosa
(generator)
Spain is one of the world’s largest wind energy producers in the
world, and leveraging their extended coastline to further their
dominant role in the industry will see enormous benefits for
country and industry alike.

Wind Power Awesomeness (VIDEO)

Siemens*, or at least the company it has commissioned to make
the video above, knows how to make a wind power advertisement.
One of the key takeaway impressions people seem to have after
visiting a wind turbine up close (or even going to the top of
one) is how entirely awesome and majestic these giant machines
are. They’re staggering in their height and power.
And I’m sure offshore wind turbines are even more impressive,
especially the 6-megawatt ones and 7-megawatt ones.
In this new Siemens video, all of this is excellently portrayed
in cinematic style — not your typical “green” or cleantech
advertisement.
Since Siemens is the company behind this excellent contribution
to cleantech messaging and wind turbine branding, I thought I’d
share more about what it has been up to in this space. Here are
a few of the company’s recent wind power highlights:
1.Siemens To Fullfil 267 MW Wind Order In Washington
2.Largest Federal Wind Farm In US Contract Awarded To Siemens
3.Siemens Opens World’s Largest R&D Test Center For Wind Turbine
Technology
4.Siemens To Provide 80 Wind Turbines For Giant German Offshore
Wind Power Plant
5.Siemens CEO: Cleantech Is A “Vital Part Of Our Business”
(VIDEO)
6.World’s Largest Wind Turbine Rotor Goes Online
Together with other wind power leaders, it should be noted that
the cost of wind power has come down tremendously in recent
years, from over 30¢/kWh 10 years ago to as low as 4¢/kWh today.
:o Notably, this cost dropped has largely been brought on by
making wind turbines larger and larger, more and more majestic.
wind turbines are getting bigger and bigger
While the cost optimization from making onshore wind turbines
larger and larger seems to be hitting a limit, larger offshore
wind turbines may provide useful benefits for the quite
different offshore wind environment. Hence the 6- and 7-MW wind
turbines. Simply look above at how a 7-MW wind turbine compares
to an Airbus A380 with a wingspan of 80 meters to get an idea of
how humungous these machines are.
*Full Disclosure: This post was supported by Siemens through Be
On media. That said, I wouldn’t have covered it if I didn’t
think it was worth covering, and nobody from Siemens or Be On
had any influence over what I wrote above.

The 120 MW Ashegoda wind farm in Ethiopia, now the largest wind
farm in the whole of Africa, officially went online last
weekend. As it stands, Ashegoda has actually already transferred
around 90 million kWh of electricity to the grid. Now that its
fully online it’s expected to produce around 400 million kWh a
year. [img width=40

/>
The project, which was announced in 2008, was constructed over
the last few years in a series of stages. When the first stage
went online, it was the first of its kind in Ethiopia.

Ashegoda is located about 18 kilometers outside of the city of
Mekelle in Ethiopia. The Adama I and Adama II wind farms were
also recently completed, boasting 51 MW of capacity each. They
are located just south of the Ethiopian capital of Addis Ababa.
The Ashegoda project was funded by the French bank BNP Paribas,
the French Development Agency (ADF), and the Ethiopian Electric
Power Corporation (EEPCo) — EEPCo will also manage the site.
Business Green provides some background on renewable energy
development in Ethiopia:
Ethiopia has one of the fastest growing economies in the world,
averaging growth of between 8% and 10% for each of the last 10
years. Last year UK Energy and Climate Change Minister Greg
Barker led a clean tech trade delegation to the country as part
of a wider mission to East Africa to help UK firms tap into what
he called a ‘huge’ opportunity for green energy.
Ethiopia has an estimated 45 GW of hydroelectricity capacity
potential, 10 GW of potential wind capacity, and 5 GW of
geothermal potential. While the government’s current five year
development plan envisages increasing the country’s current
power generation capacity to 10 GW by 2015, to date it has only
tapped around 2 GW of its green energy capacity.
With regard to the wider development environment in Africa,
renewable energy development there has been largely centered
around off-grid solar, but larger projects have been becoming
somewhat more common in recent years. For example, see:

UK Offshore Wind Capacity Rises 80 Percent in One Year
Kelvin Ross, Deputy Editor, Power Engineering International
November 08, 2013
LONDON -- The installed capacity of the UK’s offshore wind
sector has risen by 79 percent in a year. In the period from
July 2012 to June 2013, capacity increased from 1,858 MW to
3,321 MW, boosted by four huge wind farms becoming operational –
Greater Gabbard, Gunfleet Sands III, Sheringham Shoal, and
London Array, which at 630 MW is currently the biggest offshore
wind farm in the world [img width=40

HTML http://www.greenr.ca/wp-content/uploads/2010/01/uk-offshore-wind-farms.jpg[/img]
The increase is revealed in a new report, Wind Energy in the UK,
compiled by trade group RenewableUK, and it marks the first time
in a 12-month period that installed offshore capacity has
outstripped onshore, which stood at 1258 MW.
Nevertheless, onshore also saw an increase of new capacity by 25
per cent, bringing its total capacity to 6,389 MW.
Onshore and offshore, a total of 2,721 MW were installed between
July 2012 and June 2013, taking the UK’s total wind capacity up
from 6,856 to 9,710 MW — a 40 percent increase. ;D
RenewableUK says that onshore, project sizes are declining
overall, “due partly to the growth of the vibrant sub-5-MW
market under the feed-in tariff, with projects at this scale now
making up two-thirds of new onshore submissions. Other factors
include a reduction in the availability of larger sites, and
developers’ responses to changes in the planning system.”
However, the report notes that there are concerns within the
wind industry about levels of political support and the
government’s ambition for the sector, leading to a decline in
confidence.
But it points out that despite this, “there is a substantial
pipeline of projects under construction, approved but not yet
built, and in planning”.
RenewableUK’s chief executive Maria McCaffery said: “We’ve
smashed another record in the past year with more offshore wind
installed than ever before — the 79 percent increase in capacity
within 12 months is a terrific achievement. With onshore
expanding by 25 percent, the wind industry as a whole has proved
that it has the tenacity to achieve substantial growth.”

Yes. UK is leader of Offshore wind energy in the world. Though
India is 5th in the world in Wind not even a KW Offshore wind
turbine is erected! It is indeed a pity. In almost every field,
we follow west. The time has come we should be INNOVATORS rather
than remain as IMITATORS.I have been advocating Offshore Wind
Farms for over a decade in India.
[img width=640

HTML http://newscenter.lbl.gov/wp-content/uploads/wind-india-map.png[/img]
Also Wind Farm Co-operatives on the lines of those in Denmark,
Germany etc. in India. A Wind Fund can be created and
contributions to it can be exempted by Government of India under
Section 80C. This way there will be mass participation in Wind
Sector. Hitherto incentives are provided to big wind farm owners
like Depreciation. When Private participation in the Renewables
is given a big push, India can be a leading country in the
Renewables especially WIND.
What is needed are sound policies and political will to push
this clean energy.

A Good
R &D Effort in the Private Industry will help to improve the
quality of the Wind Turbines and also accurate micro siting.
HTML http://www.pic4ever.com/images/128fs318181.gif
In this connection DEWI Micrositing Experience and Research
activities have helped to get maximum output at Wind Farms in
Germany and elsewhere.
Reliable predictions of the energy yield of wind farms are only
possible on the basis of accurate near-site wind speed
measurements. The critical aspects are selection of where the
tower is to be placed, selection and calibration of anemometers,
the height of the met mast and the installation of the sensors
on the met mast. DEWI has been specialised in this area for many
years and also offers additional services such as site
calibration or long-term wind measurements for wind farm
monitoring.
Apart from the general economic conditions of a planned project,
an accurate measurement of the wind speed is the decisive factor
in determining the economic efficiency of a wind farm. An error
of 3% in the wind speed measurement can lead to a discrepancy of
about 10% in annual energy production. It is therefore
absolutely necessary to calibrate an anemometer individually
before a measurement campaign; this is offered by DEWI as an
accredited service.
DEWI’s Micrositing Department, with its longstanding experience
in services and research activities, offers investors,
developers and owners a high-quality, reliable data basis for
planning wind farm projects worldwide. DEWI offers the whole
range of services, from site inspection and analysis of existing
wind measurement data to calculation of energy yield and wind
farm efficiency and creation and optimisation of the wind farm
configuration taking into account all important parameters
specific to the site. On request, DEWI experts can also assist
in the installation of meteorological measuring equipment and
the analysis and checking of existing measurements.
For the simulation of wind and turbulence conditions in complex
terrain, DEWI Micrositing offers special 3D CFD (Computational
Fluid Dynamics) calculations, which are becoming increasingly
important in international projects. This complex, cutting-edge
calculation method allows investors, developers and owners to
obtain the best possible prediction of the real turbulence
conditions at the site.Similar methods can be adopted in India
as well and Private Wind Industry should take lead in adopting
best technology.
