Pakistan - Intention to sign MoU with China is to produce cheap wind energy in Pakistan-Tariq Sayeed

"In view of ever increasing cost of petroleum products, energy generated through wind would be available soon at much cheaper cost"

 
Chairman of Planet Energy (PVT) Ltd Tariq Sayeed said Thursday that the intention of signing the MoU with one of the China’s largest wind turbine manufacturers is to produce cheap energy in Pakistan.

He was of the view that due to unabated increase in petroleum product, the generation of wind energy would be much cheaper.

Tariq Sayeed while talking to APP from Kunming, the capital of Yunnan province said that Pakistan has so far signed 82 Letter of Intents (LoIs) for setting up wind energy projects at Wind Corridor at Keti Bunder in Sindh province.

He said that in view of ever increasing cost of petroleum products, the energy generated through wind would be available soon at much cheaper cost.

Tariq Sayeed pointed that for setting up wind energy project one has to under go a lengthy procedure and to meet various requirements.

He said that our neighbour country has achieved a great leap forward in this direction and now generating 10,000 MW wind energy.

Tariq Sayeed pointed out that with the cooperation of a foreign country, he unfolded the wind and solar energy maps for Pakistan and other regional countries in a function held in Islamabad.

He said that his company Planet Energy (Pvt) Ltd has signed a Memorandum of Understanding (MoU) with China’s largest and one of the world’s top ten wind turbine manufacturers for purchase of turbines for its planned 150MW wind farm.

With this agreement Planet Energy becomes one of the few companies of the country to be able to secure wind turbines at a time when demand of quality turbines is sky rocketing and waiting periods are estimated at 4-5 years.

He said that the company will purchase turbines to increase the capacity of its existing 50MW wind farm to 150MW. The MoU was signed in Urumqui with Goldwind Science and Technology, represented by its Vice President Wang Xiangming.

Tariq Sayeed has assured that turbines will be made available to other companies interested in developing Pakistan’s wind energy market.

He said that current energy crisis could be curtailed through cleaner technologies to reduce Pakistan?s dependence on imported fuel, which is a major contributor to its import bill.
 

 

USA - World’s largest offshore wind energy turbine to be developed in North England

California firm invests $65 million in fast growing region

 
California energy giant Clipper Windpower, Plc (www.clipperwind.com) has chosen Blyth, Northumberland in the United Kingdom as the site for a new generation of offshore wind turbines, North England Inward Investment Agency (NEIIA) has announced.

Called the “Britannia Project,” the $65 million development program advances Clipper turbine technology to a 7.5 MW wind turbine scale which will be among the largest and most powerful offshore turbines in the world. With a 30-year design life, it will generate electricity equivalent of one million barrels of oil.

North England’s Centre of Excellence for New and Renewable Energy (NaREC) will provide engineering, testing and development services in support of the project. NaREC is one of five centres of excellence set up by One NorthEast, a government agency responsible for economic development and growth for the North East region of England.
James G. P. Dehlsen, Chairman and CEO of Clipper, said: “We established the Project in support of the U.K. Government’s ambitious plans to generate more than 20% of the country’s electricity from renewable sources. This is both a responsible and necessary endeavor considering growing worldwide concerns over global warming and climate change.”

“We are also very pleased with the capability of the local area which provides excellent regional university capability for support of offshore wind technology development, particularly through the NaREC and the Marine Design Centre's expertise in marine technology and science,” he added.

Securing the investment from Clipper – which has offices across the USA, Mexico and mainland Europe – is a major coup for NEIIA which is the North American marketing arm of One NorthEast.

“We have worked with Clipper for more than two years, putting together a significant package of support for this project,” said Sean Croson, NEIIA’s Vice President, West Coast. “Our region has the engineering, research and development and manufacturing expertise to make this happen.”

He noted that NaREC’s team of consultants have practical experience across a range of renewable energy areas, including supporting marine renewables, offshore and subsea equipment, micro-renewables and high voltage electrical equipment.

Czech Republic - RWE Innogy plans to construct around 100 MW of wind farms

Acquisition of local project development company AFE Bohemia

 
RWE Innogy GmbH, Essen, is taking over six wind energy projects in the Czech Republic with a volume of 100 megawatts from project developer Aufwind Energie GmbH, Regensburg, as well as its local project development company AFE Bohemia s.r.o.. Building permission for the six locations in Bohemia and North Moravia is expected between 2009 and 2011.

“The Czech Republic has long numbered among RWE’s core markets. With the current transaction, we are securing a good starting position which will allow us to substantially grow in the area of renewable energy here“, explained Fritz Vahrenholt, Chairman of the Board of Directors at RWE Innogy.

Renewable energies currently account for 4.7 percent of power generation in the Czech Republic. By 2010, this share should increase to 8 percent. The European Commission has set a target of 13 percent for the year 2020. At present, less than 100 megawatts of wind power capacity is installed in the Czech Republic.

Jürgen Meyer, Managing Director of AFE Bohemia s.r.o.: “Together with RWE Innogy, we want to further develop the market for renewable energies in Central and Eastern Europe as it has a high potential for growth". RWE Innogy already took over wind energy projects in Hungary with a planned installed capacity of around 300 megawatts from Aufwind Schmack in March. The first building permits for these projects are expected to be granted this year.

RWE in the Czech Republic:

RWE Innogy is already represented locally with two biogas plants and several CHP plants. The company wants to continue to grow here in the areas of both wind energy and biomass.

RWE Transgas a.s. is responsible for the energy business of RWE Energy in the Czech Republic. The company coordinates the supply of gas in the Czech Republic via six “RGCs” (Regional Gas Companies) and controls the import, transit and gas shipping business. The gas lines belonging to RWE Energy subsidiary RWE Transgas a.s. form an important part of the transit route between the Russian natural gas fields and the Western European market.

UK - NWDA wind turbine spins into action

Turbine to feed directly into the Agency’s electrical supply and to have a CO2 emission saving of 9,675kg per year

 
The Northwest Regional Development Agency (NWDA), last week welcomed Helen Jones, MP for Warrington North together with Warrington Wolves’ Steve Pickersgill and Chris Bridge, to officially launch its state-of-the-art Wind Turbine.

To recognise World Environment Day later this week (5th June), the launch was observed by over 30 stakeholders from the Northwest Climate Change Partnership, the regional group responsible for implementing the Northwest Climate Change Action Plan.

Standing almost 25 metres high, the Turbine will feed directly into the Agency’s electrical supply and will have a CO2 emission saving of 9,675kg per year. Statistics relating to the energy generated will also be displayed on an interactive monitor in the NWDA’s reception area, which was also unveiled for the first time today.

After being supplied by Scottish firm Proven Energy, the Turbine has become a real Northwest affair, installed by Cumbrian company Wind Turbine Services. HFM Consulting Engineers Ltd based in Manchester and Liverpool also provided assistance with the planning application and project management.

The Turbine benefits from an advanced technology dampening system that allows it to continue operating even in extreme weather conditions. Hinged blades automatically fold inwards to ensure a constant spinning speed and allow the optimum amount of energy to be generated. This model was the first to be supplied by the manufacturer with this innovative capability.

As part of the Northwest Regional Economic Strategy (RES) the NWDA works with partners to promote energy efficiency and recognises the need to utilise alternative energy sources to ensure continued sustainable growth for the region.

Welcoming guests was Steven Broomhead, Chief Executive of the NWDA, who said:

“I am delighted with the Wind Turbine, which will act as a symbol of the Agency’s commitment to helping sustain the Northwest’s future energy requirements.

“My thanks goes to Helen Jones, MP for Warrington North, Steve and Chris for joining us today and helping us celebrate this significant step forward in reducing our carbon footprint and assist with reducing the impact of climate change.

Helen Jones, MP for Warrington North comments:

“You cannot fail to notice this new addition to the Warrington landscape and I am thrilled to be able to be here to mark the launch.

“It has never been easier for businesses and homeowners to invest in sustainable energy, with a wealth of assistance readily available. The effects of climate change are already being felt and will continue to become an increasingly important issue.”

India - State’s largest wind farm to begin operation from 2009

50-MW wind farm located about 160 km from Kolkata at Dadanpatra near the sea resort of Digha

 
Wind energy major, Suzlon group, will begin generating power from Rs 500-crore project in West Bengal — the largest wind farm in the eastern region —from 2009.

The 50-MW wind farm, located about 160 km from Kolkata at Dadanpatra near the sea resort of Digha, will require about 700 acres of land. The project will be financed through and debts and internal accruals.

“Land has been identified and it is in the process of transfer. The major challenge is to bring large wind farm equipment to the site from our production base in south India,” said PM Rao, General Manager (marketing) of Suzlon Infrastructure Services Ltd (SISL) and also project in-charge.

The power generated from the farm will be purchased by the West Bengal government at Rs 4 per unit. Rao said that the West Bengal government should make the Power Purchase Agreement (PPA) for 10 years instead of the current five years agreement.

“Breakeven for a wind power project is seven years and with a five year PPA it is difficult to make the project bankable,” he said.

Turkey - Fifteen wind power plants coming to Çeşme

460 million euros to be invested over the next three years

 
Fifteen wind power plants at a total cost of 460 million euros will be established over the next three years on the Çeşme peninsula, an area with the highest terrestrial wind potential in Europe.

The issuance of licenses for wind power plants had been halted for 10 years due to lack of transmission lines to the region. However, the Energy Market Regulatory Agency (EPDK) has approved the applications for 15 wind power plant licenses from major conglomerates, including Çalık, ENDA, Ayen, Güriş and Bilgin Enerji.

The plants will have electric capacity varying between 10 megawatts (MW) and 50 MW. When completed the total capacity of plants in Çeşme will be 426 MW and the annual electricity production will reach 1.6 million kilowatt hours (KWh). EPDK President Hasan Köktaş told the Anatolia news agency that this is a major step in turning Çeşme's energy potential into actual electricity.

Köktaş said the private companies that acquired the licenses in the region would also undertake the installation of transmission lines to the national electricity grid, which, he stated, will cost around 10 million euros.

Currently there are 13 wind power plants in Turkey with 249 MW capacity; this number will climb to over 470 MW with the addition of four new power plants by the end of this year.

Germany - Husum WindEnergy 2008 and the German Wind Energy Institute (DEWI) present WindEnergy Study 2008

Annual new installations worldwide to increase from 20 000 MW to 107 000 MW. Globally, there could be some 718 000 MW installed wind capacity by 2017

 
The international wind energy industry takes a very positive view of further development of the worldwide wind energy market in the coming years. Thus the world market volume of annual new installations is expected to be multiplied by five within ten years, from about 20 000 MW in 2007 to about 107 000 MW in 2017. The results of the fourth WindEnergy Study were presented in Berlin today – they were commissioned by Husum WindEnergy 2008 with the German Wind Energy Institute (DEWI) in the run-up to the industry's leading international fair. As the survey of companies active in this international industry showed, there could be a total of some 718,000 installed wind power worldwide by the end of 2017 (compared with about 94 000 MW at the end of 2007).

“This survey gives the companies in the industry a vital preview of the markets of the future. Its results are also reflected in the structure of the leading international trade fair of the wind energy industry, Husum WindEnergy, with exhibitors from 35 countries, including national pavilions from the USA, Canada, France and the UK, and with visitors from 40 countries, that is from the growth markets,” says Hanno Fecke, Managing Director of the Husum Trade Fair. “The Wind­Energy-Study has provided a continuous set of data over the years, giving the industry an outstanding overview and a valuable forecast of the development of the global wind energy market,” says Bernd Aufderheide, Chairman of the Management Board of Hamburg Messe und Congress, which is the cooperation partner of Husum Trade Fair.

The data for Germany are applicable for the time of the survey, that is before the amendment of the Renewable Energies Act and thus before the decision on new conditions. They show possible total installation of 31 800 MW by 2012, of which 28 000 MW is onshore and about 3 800 MW offshore. The figure for 2017 is a total of 44 000 MW installed power, of which 32 500 MW onshore and 11 500 MW in the North Sea and Baltic Sea. That means about 13% more installed power onshore than was forecast in the 2006 Study. A scenario shown at the same time in the WindEnergy Study of the German wind market up to 2030 also gives a very much more positive view than two years ago. It indicates that there could be a total of as much as 65 000 MW on stream in 2030 (onshore and offshore), meeting about 31% of gross German power demand. That would mean some 35 100 MW installed onshore (i.e. about 7 200 MW more than was forecast in 2006) and some 30 000 MW offshore.

“The WindEnergy Study 2008 forecasts strong continuous growth for the global wind industry,” says Thorsten Herdan, Managing Director of the Manufacturers’ Association VDMA Power Systems. “For 2017 we are talking about a total sales volume of well over 100 billion euros. To realise this optimistic forecast, German manufacturers and equipment suppliers, who account for more than one third of total sales volume in the wind industry, would have to make another massive increase in their production capacities for turbines and components. A continuous home market for onshore and offshore wind energy, and sufficient skilled manpower, is essential to bring these enormous investments to Germany.” Hermann Albers, President of the Federal Wind Energy Association (BWE), sees Germany as the clear winner in the global wind energy boom, and notes that “the German export quota of some 80% of manufactured components and turbines is safeguarding and creating more and more jobs –more than 80 000 of them already today.”

The companies surveyed suppose steady development in the European market in the next five years. They are expecting some 129 000 MW installed power by 2012, as compared with 57 136 MW at the end of 2007. Global installed power is expected to reach 288 000 MW by 2012 (versus 94 000 MW at the end of 2007). The study predicts that by 2012 more than half the installed wind turbine power will be outside of Europe, as compared to only 39% in 2007. That shows how fast the non-European markets are catching up with Europe in use of wind energy, and just how much potential this market holds.

The focus of worldwide growth last year was in the USA, China, Spain, Germany and India, with some 78% of new installations. The respondents feel that the USA, China and Spain have great growth potential into the future, and there are also other countries that are becoming important to them, such as Greece and South Korea. The extension of tax benefits for wind energy adopted by the US Senate (PTC) by the end of 2009 (the decision by Congress is still pending) will most likely enable the US wind industry to continue breaking records in the next two years. The majority of companies surveyed feel that the US market will survive even without extension of PTC, as various states are funding wind energy.

“The WindEnergy Study provides impressive proof of the sustained upswing for wind energy worldwide” says Steve Sawyer of the Global Wind Energy Council (GWEC). “The market growth shown in the study, that is some 20% per annum worldwide up to 2017, is a great opportunity for the industry, the labour markets, and for climate protection.”

In China a total of 44 manufacturers installed new turbines with total capacity of 3 499 MW in 2007. Nearly two thirds (62%) of respondents feel that this development gives them good chances of participating in the Chinese market. As many as 19% of the companies participating in the survey see opportunities for themselves to develop wind farm projects in China – mostly in the framework of joint ventures. Respondents feel that the competitors growing up rapidly in China will be competing in the world market from 2010 onwards.

HUSUM WindEnergy 2008 – the leading international wind industry fair – has for the first time been organised as a cooperation venture between the Husum Trade Fair and the Hamburg Trade Fair. From 9 to 13 September, some 700 exhibitors from 35 countries will present their products and services at the Husum trade fair site, including the world’s leading wind turbine manufacturers and their equipment suppliers. This fair is dedicated to the wind industry, and will be the international meeting point and forum for companies and trade visitors for five days.

Philippines - SMART cellsites using wind and solar power

Hybrid wind- and solar-powered cellsite system serves as a reliable, efficient and economic alternative to the fuel generator, which is commonly used in powering cellsites

 
Smart Communications Inc. is using wind and solar energy in operating its cellsites in remote areas, including one in Punta Bulata in Cauayan, Negros Occidental, a press release from the company said.

At present, it is using hybrid wind and solar power in 11 cellsites situated in Tanudan in Kalinga; Ba-ay-Licuan and Luba in Abra; Cagayancillo and Busuanga in Palawan; San Isidro, Hinabangan and UET Catarman in Samar; Boracay in Aklan; Sarangani in Davao del Sur; and in Cauayan,Negros Occidental.

Jun Costes, senior manager of Network Services Division, said that for 2008, the company is aiming to deploy another 34 eco-friendly cellsites, 19 of which will be wind-powered and 15, hybrid solar- and wind-powered.

Not all cellsites have potential wind source, so solar energy was the obvious easily available energy, he said in the press release.

The press release also said its first wind-powered cellsite was installed in Malapascua Island in Cebu in December 2006. Late last year, it deployed 33 more renewable energy-powered cellsites, including 11 which are hybrid wind- and solar-powered.

It said the hybrid wind- and solar-powered cellsite system serves as a reliable, efficient and economic alternative to the fuel generator, which is commonly used in powering cellsites. Compared to diesel-driven generators that need monthly refueling, produce carbon dioxide emissions and entail costly replacement of engine oil and filters, the hybrid wind- and solar-powered system require minimal maintenance.

NSD senior engineer Davidson Sevilleja said in the press release that solar cells made from semiconductor materials convert sunlight directly into electricity, adding that during the day when the wind speed is low, solar power becomes the primary source of power of the cellsites.

Sevilleja said that at night, the wind turbines deliver electricity to the cellsite.

The press release added that the use of hybrid wind- and solar-powered cellsites translates to reduced operational expenses because the electricity cost is almost free and the high cost of hauling fuel to the cellsite has been removed.*

Norway - StatoilHydro to build world's first full scale floating wind turbine

2.3MW wind turbine is attached to the top of a so-called spar-buoy, a solution familiar from production platforms and offshore loading buoys.

 
Norwegian energy company StatoilHydro has decided to build the world's first full scale floating wind turbine, Hywind, and test it over a two-year period, offshore Karmoy, Norway. The company is investing approximately NOK400 million, with startup planned for autumn 2009.

StatoilHydro has said that a 2.3MW wind turbine is attached to the top of a so-called spar-buoy, a solution familiar from production platforms and offshore loading buoys.

The rotor blades on the floating wind turbine will have a diameter of 80m and the nacelle will tower some 65m above the sea surface. The floatation element will have a draft of some 100m below the sea surface, and will be moored to the seabed using three anchor points. The wind turbine can be located in waters with depths ranging from 120-700m.

The pilot project will be assembled in Amoyfjorden near Stavanger, Norway, and is to be located some 10km offshore Karmoy in the county of Rogaland. The wind turbine itself is to be built by Siemens.

French engineering group Technip will build the floatation element and will have responsibility for the offshore installation. Nexans will lay cables to shore, and Haugaland Kraft will be responsible for the landfall.

Alexandra Gjorv, head of new energy at StatoilHydro, said: "We have drawn on our offshore expertise from the oil and gas industry to develop wind power offshore. Taking wind turbines to sea presents new opportunities. The wind is stronger and more consistent, areas are large and the challenges we are familiar with from onshore projects are fewer."

 

 

Nordex scoring again in the United Kingdom

Hamburg - Nordex AG has since received the fifth new contract for this year from the United Kingdom. The Company will now be supplying wind turbines with an output of some 70 megawatts with a total value of around EUR 70 million to this country. The latest project concerns extensions to the “Crystal Rig” wind farm with the addition of five N80/2500 KW turbines in a contract worth EUR 10 million.

In 2003, Nordex had constructed 20 N80 turbines close to the small Scottish town of Dunbar. With an installed capacity of 50 megawatts, “Crystal Rig” is one of the largest wind farms in operation in the United Kingdom. “In my view, the fact that Fred Olsen Renewables has opted for Nordex again testifies to the confidence which it has in our technology,” says Carsten Pedersen, COO Sales and Marketing at Nordex AG.

And the wind farm developer is in good company. This year alone, two other Nordex customers – including UK utility Npower – have opted for this turbine. Generally speaking, what was decisive was the robust design of the turbine, which is certified for strong-wind sites. In the past few months, Nordex has received orders for 22 of its N80 turbines from the United Kingdom to join the 30 units already in operation there.

Including the projects under construction, Nordex UK has to date installed roughly 200 megawatts worth around EUR 160 million. The Company is also providing maintenance services for most of these turbines. Explains Pedersen: “Our customers often attach key importance to OEM service, which is why we want to further extend our service in the UK. In fact, we are currently holding negotiations with a number of customers on new projects.”

The United Kingdom is one of Nordex’s most important markets on account of the strong projected growth. Experts assume that new installation of the industry will expand in 2006 by around 40% to some 600 megawatts. Contrary to original assumptions, demand is focusing on onshore turbines.

 

Vestas receives an order for 31 units of the V82 turbine in Spain

The Vestas Group has received an order from the reputable Spanish wind farm developer, Parque Eólico de Alentisque S.L. for 31 units of the V82 turbine. The order is a turnkey order and also includes a VestasOnline™ remote monitoring system.

The project will be located in the region of Castilla y León, in the west central part of Spain. Vestas has in total installed 233 MW in the region which is the third largest region in Spain in terms of installed wind power with more than 2,000 MW installed as per 31/12/2005.

Vestas is already represented in the region with two factories. “In 2003, Vestas built a control system factory in Soria, and this year we have completed the construction of our V90 nacelle production unit in Villadangos. The fact that Parque Eólico de Alentisque S.L. has chosen Vestas as supplier for their project is a further strengthening of our presence in Castilla y León” says Ebbe Funk, President of Vestas Mediterranean A/S.

Delivery of the turbines will begin in November 2006, and the wind power plant will be completed in 2007. The wind power plant is estimated to produce 136,000 MWh per year, which corresponds to a saving of 74,528 tons of CO2 emission to the atmosphere.

The above order does not affect the Vestas Group’s expectations for 2006, cf. Stock exchange announcement No. 16/2006 of 29 March 2006.

Vestas receives its first order for V52-850 kW turbines in Spain

The Vestas Group has received its first order for V52-850 kW wind turbines in Spain. The customer is the utility Enel Unión Fenosa Renovables S.A., which is one of Spain’s largest renewable energy promoters and a long time customer of Vestas.

The wind power plant consists of 20 units of the V52-850 kW turbine and will have a total installed capacity of 17 MW. The wind power plant called Codesas 1 will be located in the region of Galicia in the north-west of Spain.

The order comprises supply and commissioning of the turbines as well as a VestasOnline™ remote monitoring system. The scope also includes service and maintenance during the first five years of operation. Delivery of the turbines will begin in November 2006, and commissioning is scheduled to take place in the spring of 2007.

“Vestas has installed more than 1,600 units of the V52-850 kW turbine all over the world. It is one of the most adaptable wind turbines in our product range, and this order shows the competitiveness of Vestas and of this well-proven turbine on the Spanish market,” says Ebbe Funk, President of Vestas Mediterranean A/S.

Siemens receives new U.S. orders for 70 wind turbines for Texas

Siemens Power Generation’s (PG) wind power division has received an order for 161 megawatts (MW) of wind turbines for the Wildorado Wind RanchTM, which will be located near Amarillo, Texas. These turbines have the potential to meet the electricity demand of more than 50,000 households. The Siemens scope of supply consists of 70 2.3 MW MK II turbines, including towers and transportation to the site, installation, startup and commissioning, and a five year service and maintenance agreement. The project is scheduled for commissioning in spring 2007. The Wildorado Wind RanchTM was developed by Cielo Wind Power, LP, of Austin, TX in conjunction with Edison Mission Group (EMG) of Irvine, CA.

Siemens Power Generation is demonstrating a strong growth in the wind energy business. Last year, the company almost doubled its production capacities for wind turbines. In 2005 Siemens PG signed a contract for one of the largest wind orders in the world. For Florida Power and Light Energy, LLC, the company erects wind farms with a total installed capacity of 600 MW at various U.S. sites.

Within the past year, wind power projects in the U.S. increased in total capacity by 2,431 MW, with an investment volume of more than USD3 billion. This resulted in an increase of 36 percent, which puts the U.S. at approximately 9,149 MW of installed capacity of wind power. For the current year, experts forecast a further increase in demand for wind farms. “Due to the U.S. Congress’s prolongation of the production tax credits for wind power, and due to the high prices for oil and gas, this market experiences positive developments now and in the near future,” said Andreas Nauen, head of the wind power division of Siemens PG. “With many states in the U.S. implementing renewable portfolio standards wind power is clearly becoming a mature and more stable long term market. Siemens Wind Power expects to be a very strong player in the U.S. wind market,” Nauen added.

The Power Generation Group (PG) of Siemens AG is one of the premier companies in the international power generation sector. In fiscal 2005 (which ended September 30), Siemens PG posted sales amounting to approximately EUR8.1 billion and received new orders totaling EUR11 billion. Group profit amounted to EUR951 million. On September 30, 2005, PG had a work force of approximately 33,500 worldwide.

The myth of intermittency


 

It is widely perceived that because the wind resource is intermittent, the wind technology is not ‘reliable’ enough to be a major power source.

Watching a single wind turbine stop and start, it might seem logical to conclude that, as more of these machines are built, the result can only be an unreliable supply.

The entire electricity system is variable, like wind energy. Both supply and demand of electricity are infl uenced by a large number of planned and unplanned factors. The changing weather makes millions of people switch on and off their supply. Millions of others expect instant power for lights, TVs, computers.

Conventional power sources are intermittent.

On the supply side, no power station of whatever type is completely reliable. Large power stations that go off-line, whether by accident or for maintenance, do so instantaneously, causing immediate loss of power. When a fossil fuel or nuclear power plant trips unexpectedly, it takes a capacity of up to 1,000 MW off the network instantly. That is true intermittency.

Power systems have always had to deal with these sudden output variations, as well as variable consumption, and the procedures put in place by network operators can be applied to deal with variations in wind power production as well.

Variability and intermittency are different concepts.

Variations in wind energy are smoothed by the fact that there are hundreds or thousands of units in operation, making it easier for the system operator to predict and manage changes as they occur. The system will not notice the shut down of a 2 MW wind turbine, but it will have to respond to the removal of a 500 MW coal fi red plant or a 1,000MW nuclear plant. Wind energy does not suddenly trip off the system.

So the issue is not one of variability in itself, but how to predict, manage and ameliorate electricity variability and what tools can be utilised to improve efficiency. Wind power is variable in output, but this can be predicted to an increasingly accurate extent.

The electricity system, not the turbine is what matters.

It is the net output of all wind turbines on the system or large groups of wind farms that matters for electricity needs. Wind power has to be considered relative to the overall variability of demand and the intermittency of other power generators.

The wind does not blow continuously in one place, yet there is little overall impact if the wind stops blowing somewhere – it is always blowing somewhere else.

Therefore wind can be harnessed to provide reliable electricity even though the wind is not available 100% of the time at one particular site. In terms of overall power supply it is largely unimportant what happens when the wind stops blowing at a single wind turbine or wind farm site.
bullet
The more wind farms that are built over a wider geographical location, the more reliable wind energy is.

The EWEA report “Large scale integration of wind energy in the European power supply” analyses these issues in depth. The report’s main conclusions are that the capacity of Europe’s power systems to absorb significant amounts of wind power is determined largely by economics and regulatory rules rather than technical or practical constraints. Already today, it is generally considered that wind energy can meet in the region of 20% of electricity demand on a large electricity network without posing any serious technical or practical problems – as proven by the example of Denmark.
