Faulty wind turbine blade blamed for collapse at Raleigh Wind Power facility

CTV London reported that a faulty wind turbine blade was the cause of a tower collapse in Chatham-Kent. The 160-tonne structure at the Raleigh Wind Power facility in Dillon, near South Buxton, collapsed early in the morning on January 19. The incident did not cause any injuries and did not destroy any buildings.

A spokesperson with Terra Form Power said that a review by independent third-party professionals, as well as the company's own engineering team, concluded the collapse was caused by a single blade.

Chad Reed said no other similar issues were identified during the review process.

At the time, the 22 remaining turbines on the wind farm were taken off-line as a precaution, but returned to service Feb. 14.

Mr Reed said that his company will regularly and rigorously monitor all turbines as part of the ongoing review and maintenance process.

The turbines at the Raleigh facility went online in January 2011.

First leg of Turkish Stream gas pipeline to be completed in early May - Gazprom

Gazprom CEO Mr Alexei Miller said that the construction of the first leg of the Turkish Stream gas pipeline will be finished in the first 10 days of May. "Everything is going according to plan to date, 1,047 kilometers [some 650 miles] have been laid, which is 55 percent of the total length of the offshore section of the gas pipeline."

Mr Miller said that "As to the first leg, 827 kilometers have been built and in the first ten days of May we will finish the construction of the first leg of the pipeline. What remains is to build a receiving terminal and the second leg, so everything goes according to plan."

The Turkish Stream project presupposes the construction of two conduits of the main gas pipeline along the bottom of the Black Sea, with an annual capacity of 15.75 billion cubic meters of gas each.

One route is designed to deliver gas directly to the Turkish market and the other is for transit gas supplies through Turkey to European countries.

On August 2, US President Donald Trump signed a bill imposing sweeping sanctions on Russia, Iran and North Korea. In particular, the anti-Russia sanctions target the country's defense and economic sectors, restrict dealings with Russian banks and energy companies, as well as counteract the construction of the Nord Stream 2 pipeline.

Wind Farm is one of the oldest human technologies

Wind power is arguably one of the oldest human technologies. Today, wind power is symbolized in most people’s minds by a big, white, monolithic wind turbine. As we try to move into the post-carbon era, it’s worth remembering that only wind, nuclear, and solar have the same technical potential to provide energy as fossil fuels do today. Perhaps the face of future power generation won’t be huge smokestacks, but fields of wind turbines.

A wind farm is any group of wind turbines that, together, generate a sizeable amount of electricity and act as a power plant. Individual wind turbines were used to generate electricity as far back as 1887. Professor James Blyth of Glasgow constructed a 10m windmill that charged an early battery, which he used to power the lights in his home although those living in the local town of Marykirk turned him down when he offered to light the main street from this windmill, saying that “electrical power was the work of the devil.” Devil’s work or not, we all rely on it to an increasing extent in the modern world.

It took nearly a century from Professor Blyth’s windmill for the modern, industrial-scale harvesting of wind energy to take root. The first modern wind farm was constructed in 1980, in New England. Like so much renewable energy research and development, it was sparked by the oil/energy crisis of 1973, which led the Carter administration to invest in solar and wind power as alternatives to dependence on foreign oil. This wind farm used 20 small wind turbines to generate 0.7 MW of power; they’ve grown in size since then.

Large wind farms can consist of hundreds of turbines spread over a large area of land; the largest wind farm in the world is the Gansu wind farm in China. The aim was to have 20 GW of power capacity installed by 2020; currently, 6.5 GW has been installed – over 7,000 wind turbines. The winds that sweep in over the Gobi desert have proved fertile ground for this new kind of farm.

Various estimates have been made for the global potential for wind power, with the most optimistic suggesting that we could generate many times more electricity than the world currently consumes using a combination of onshore and offshore wind farms. Lu et al, for example, suggested that wind turbines could provide more than 40x current global electricity consumption and several times our global energy consumption in all forms. However finding the appropriate location for wind farms has proved a difficult challenge.

Naturally, you need wide-open space, although the area between turbines can be used for certain kind of agriculture (typically grazing land.) At the same time, you need an average wind-speed of greater than around 4.5 m/s to be economical the faster the windspeed, the quicker the project will pay for itself and begin realising profit, so this is an important factor.

Consistent windspeeds throughout the year are ideal for the stability of the grid, and it’s usually considered advantageous to build the windfarms at height or in flat regions where the windspeed isn’t disrupted by orography or man made structures. Some regions can provide particularly good windspeeds an example is ‘micrositing’, where wind turbines are placed on ridgelines to take advantage of the acceleration of the wind due to the sudden change in topography.

These requirements must be balanced with the need to build the wind farm reasonably close to places that need a power supply, such as cities. If the electricity has to be carried a great distance, even with high-voltage DC cables, the losses can render the power plant less economical than it would be otherwise.

However this consideration has to be balanced with the prospect that some people find the wind turbines unsightly in the countryside a phenomenon called NIMBYism (Not In My Back Yard.) Typically site selection for wind farms requires consideration of all of these factors, followed by a measurement campaign to narrow down between sites that meteorological data suggests will be useful.

A more recent phenomenon has been the creation of off-shore wind farms. The first of these was installed in Denmark in 1991, and they have grown in stature since. Opening up the ocean wind resource to exploitation increases the area that wind turbines can cover. It’s also the case that wind can be substantially stronger offshore; driven by the heating of the oceans during the day, that sea breeze can be strongest in the afternoon, when power demand is increased.

Typically it’s considered best to locate them just offshore from major coastal settlements, reducing the length of electrical cable and associated losses. Until 2017, most wind farms were fixed-foundation – this required them to be built in shallow waters less than around 30 m in depth, allowing bases for the wind columns to extend down to the sea floor. Renewable energy fans will be interested to watch the progress of the world’s first floating wind farm, which could potentially allow wind potential from the deep ocean to be harnessed.

The floating wind farm, consisting of five 175 m turbines, started supplying power to Scotland in October 2017. Early indications are that it is operating at high capacity, and, with further development, it may prove to be a major player in the coming energy transition.

NSW approves 1,000MW Liverpool Range wind farm in New England

The New South Wales state government has given planning approval for the Liverpool Range wind farm, which at more than 1,000MW could be the biggest in the country. The wind project is being developed Australian renewable energy company Epuron and the planning permission allows for 267 turbines on 25 different properties between the villages of Coolah and Callisis east of Mudgee.

Depending on the final choice of wind turbine, the project could exceed 1,000MW. It will stretch 36km from north to south and 20km east to west in the heart of the New England Tablelands, and part of it will be within the electorate of former National leader Barnaby Joyce.

The Liverpool Plains area to the north is one of the richest farming regions in Australia, but unlike the hotly-contested Shenhua coal mine north of the project, the wind farm will not get in the way of farming activities.

Epuron has been working on the project for seven years, and received its planning approval just over a week ago. All going well, and subject to the delivery of the project to an un-named, but identified buyer, construction could begin within a year.

Epuron said that the Liverpool Range wind project would be a key part of the transition to renewable energy as more coal fired power stations closed down, reducing emissions and saving significant quantities of water now used in coal generators.

Epuron executive director Martin Poole said that “I think we will start to see people talking more about power rather than renewables, and over the next coulee of years, most of that power will come from renewables.”

NSW Planning Minister Anthony Roberts said the project would create 800 jobs and provide a significant economic boost to the local community. It was approved after changes were made to take into account concerns about noise and visual impacts, biodiversity, and construction traffic.

The number of turbines was cut by 16, some required increasing setbacks, and the number of proposed substations was reduced from six to four.

Mr Poole said the project was agreed after consultations with a local community consultative committee that included landowners, neighbours and local businesses and local councils.

A Community Enhancement Fund will provide USD 800,000 per year (based on USD 3,000 per wind turbine built), the water saved from not burning coal would amount to 6,000 Olympic sized swimming pools a year, and emissions saved would be 2.4 million tonnes a year.

Mr Poole said that “Epuron thanks the community for coming on board with this wind farm. After almost 15 years working on wind and solar projects around Australia, Epuron continues to be committed to the clean, new energy system that Australians, and importantly our children, expect and demand.”

Mr Poole told RenewEconomy that the Liverpool Range project would go ahead with “any reasonable policy outcome.” He noted that the ongoing uncertainty over the last 10 years has made it difficult “for all sorts of power projects”.

Nordex wins three contracts in Turkey

The Nordex Group is experiencing a made-to-measure end to the first quarter of 2018. It has now been awarded three contracts for a total of 47 multi-megawatt turbines in Turkey from existing customers. These entail N131/3600 and N131/3900 turbines, while the combined installed capacity of the three projects comes to 178.8 megawatts. In addition to supplying the turbines, Nordex will also be providing multi-year service. Delivery of the turbines for the first wind farm will be commencing in September this year.

With a market share of around 30%, Nordex is one of the leading suppliers of wind power systems in Turkey. This gives the Group extensive experience in this country, where it has established a dense network of service stations. Mr Ibrahim Oezarslan, Head of Sales Europe said that “This together with our ideally suited products ensuring a high capacity factor in the projects was the decisive reason for our success.”

Eneco inked new contracts with Siemens Gamesa, ØER Energy, GEV Windpower and MPI Contractors

The Prinses Amalia wind farm started to generate its first green power more than ten years ago. Since they came on stream, the park's 60 Vestas V80 turbines, each with a capacity of 2MW, have generated over 400 GWh every year. Partly due to the expiry of the existing government subsidy, the park, which is technically in good condition, reaches a phase in which smart asset management becomes even more important. With this in mind, Eneco recently concluded a number of new management and maintenance contracts for the wind farm.

OER Energy A/S, a subsidiary of the Norwegian company NSG Wind, won the European tender for supplying technicians specialised in the replacement of main components. Since the beginning of this year, all transport and lifting services are provided by MPI Contractors, for which it will use one of its crane vessels. The tender for the maintenance of rotor blades was won by GEV Windpower and Siemens Gamesa won the tender for the supply of gearboxes. MHI Vestas Offshore Wind – Eneco’s partner in several offshore wind projects – will continue to carry out the regular preventive maintenance for the next five years.

Arjan Donker, Operational Manager Offshore Wind at Eneco said that "We have an extensive portfolio of both existing wind farms and projects in the pipeline. Consequently, it is essential to continuously keep an eye out for better, smarter and more cost effective management and maintenance possibilities. This is particularly important for a wind farm that has to operate without financial support in the form of subsidy. We are proud that the new contracts that we have concluded will enable the park to continue to operate on a financially sound basis during the coming years."

New partners help Eneco to further bring down the cost level. This not only relates to lower prices for services provided, but also to more efficient maintenance planning. For the coming years the costs related to replacement of the main components are minimised by optimising the use of the most expensive component, which is the crane vessel. This makes it possible to combine the replacement of a number of main components, such as gearboxes, generators and/or rotor blades, in a single maintenance operation. In addition, we have opted for a flexible planning mechanism, which gives MPI Contractors room to optimise the use of their crane vessel in several projects.

Driving force
The groundbreaking offer made by the consortium consisting of Eneco, Shell, DGE and Van Oord at the end of 2016 for the construction of the offshore wind farms Borssele 3 and 4, confirms that Eneco is one of the driving forces behind improving the cost efficiency of wind energy. Smarter asset management is an important ingredient to bring down the cost level of offshore wind energy even further. Donker concludes: "It is also crucial for the realisation of our strategy, which is to accelerate the transition to sustainable energy."

Stormachtige ontwikkelingen rond wind op zee

Het stormt achter de horizon. De komende tijd verrijst er bijna jaarlijks een nieuw windpark op zee. Vooral de Noordzee wordt een drukke bouwplaats, met steeds grotere turbines, installatieschepen, helihavens - en lagere kosten.

Foto: HH. (zie bijlage)

Jan Bruggenthijs, topman van Sif Group, zei het een beetje terloops. Het was augustus 2017 en in een zaaltje op het hoofdkantoor van ABN Amro aan de Zuidas had hij net een toelichting gegeven op de tegenvallende halfjaarcijfers. Bruggenthijs, die in mei vertrekt bij het bedrijf dat funderingen windturbines maakt, sprak over de 'snel dalende kosten voor wind op zee'.

Jan Bruggenthijs.Foto: Peter Boer.
Die kostendaling is gunstig voor de consument. Maar raakt het steeds goedkoper worden van windenergie niet de verdiencapaciteit van de toeleveranciers?
'Het gaat om efficiency', doceerde de boomlange topman van Sif. Het bedrijf uit Roermond was mede daarom verhuisd naar Rotterdam. Dat ligt pal aan de Noordzee, waar de enorme stalen funderingen - in jargon: monopiles - uiteindelijk komen te staan.

'Onze kade is uitgebaggerd in opdracht van het havenbedrijf. Op de bodem is zand gelegd,' vertelde Bruggenthijs. Schepen die de monopiles ophalen staan dan op poten die ze even laten zakken. 'In de klei zakten die poten weg. Dan duurde het laden van die schepen twee dagen', zei Bruggenthijs. 'Met de zandondergrond, die door de poten van het laadschip nog verder wordt aangestampt, duurt het laden 14 tot 18 uur. Dat scheelt nogal, aangezien de huur van zo'n schip $ 250.000 per dag is. En zo zoekt de hele keten naar een hogere efficiëntie.'

Optuigen toevoerketen
Dit is het kernverhaal van windenergie: de hele toevoerketen moet worden opgetuigd om zo gestroomlijnd mogelijk te werken. Het is schaken met de elementen, met miljardenbedragen en met technische vooruitgang. Want dat is een andere cruciale variabele in de windindustrie: de letterlijke groei van de turbines, waardoor de opbrengst stijgt en de kosten worden gedrukt.
Windenergie is schaken met de elementen, met miljarden en met technische vooruitgang

'Groot, groter, grootst' wordt daarmee realiteit in offshore wind. Dit proces verloopt momenteel explosief. Turbines van 3 megawatt die vier jaar geleden nog op zee werden neergezet zouden bij huidige aanbestedingen niet eens meer meedoen: ze zijn te klein.

Het Zweedse staatsbedrijf Vattenfall won vorige maand de laatste tender, zonder subsidie, voor de aanleg van windpark Hollandse Kust Zuid. In 2022 moet het zijn gebouwd. Vattenfall moet sommige details nog inkleuren, zei Gunnar Groebler, topman van de winddivisie, in maart op een steenkoude kade in Schiedam, vlak nadat bekend werd dat het moederbedrijf van Nuon de aanbesteding had gewonnen. Zo was het nog niet duidelijk wat voor type turbines Vattenfall gaat neerzetten in de Noordzee. Maar, zo verzekerde Groebler, 'het is zeker dat het turbines worden met een opwekcapaciteit van 8 megawatt.'

Ondertussen werkt GE al aan turbines van 12 megawatt. De ontwikkeltijd is drie tot vijf jaar, meldde dat Amerikaanse conglomeraat begin maart. Schaalvergroting van de turbines zullen uiteindelijk ook de kosten drukken, verwacht GE. Nog een claim: hun windmolens zullen 45% meer energie leveren dan de huidige.

Ook de installatieschepen voor de windturbines worden steeds groter. Van Oord investeerde tientallen miljoenen om het installatieschip Aeolus gereed te maken voor turbines van 8 tot 10 megawatt, de huidige maat der dingen.
Voor de volgende generatie, zoals die van GE, zijn er nog weer grotere schepen nodig. Schepen met kranen die tot 5000 ton kunnen heffen: dat is vijf miljoen kilo, ofwel het gewicht van alle bezoekers van een uitverkochte Arena bij elkaar, er vanuit gaande dat iedereen 92 kilo weegt.
‘IJmuiden, de Eemshaven en Vlissingen zouden goede locaties zijn voor minivliegveldjes.’• Conny van den Hoff

Record na record
Zo dendert de offshore-windindustrie door. Europa - en dan vooral de Noordzee, vanwege de geringe diepte - is goed voor het leeuwendeel van het geïnstalleerde vermogen van wind op zee. De records worden achter elkaar gebroken. 2017 was een recordjaar voor geïnstalleerd windvermogen, meldde branchevereniging WindEurope. Er is ruim 3000 megawatt aan vermogen bijgekomen. Het jaar daarvoor was dat 1600 megawatt.

Nederland wil tot aan 2023 vijf parken van 700 megawatt (enkele honderden molens) aan windvermogen op de Noordzee. Dat is nog maar het begin, want daar moeten er nog eens zeven windparken komen van elk 1000 megawatt. Samen met de relatief kleine windparken die er al staan, komt het totaal op zo'n 11000 megawatt. En daarmee stopt het nog zeker niet. Tennet ontvouwde twee jaar geleden het plan om een eiland aan te leggen op de Doggersbank.
Nog zo'n plan: meerdere helihavens om de enorme windparken te kunnen bereiken. Dit idee komt van Den Helder Airport, de luchthaven waarvan nu nog alle helikoptervluchten van en naar de olieplatforms worden uitgevoerd. IJmuiden, de Eemshaven en Vlissingen zouden goede locaties zijn voor minivliegveldjes, zei Conny van den Hoff van Den Helder Airport vorige zomer.

Verbinding zoeken
Het wordt de komende jaren druk op de Noordzee. 'Er spelen hier meerdere belangen: de visserij, de scheepvaart, de olie- en gassector, en in toenemende mate de windenergie', zei Floris van Hest, directeur van Stichting De Noordzee, de afgelopen herfst.

Om de klimaatdoelstellingen van Parijs te halen, zal waarschijnlijk 10% of meer van het zeeoppervlak gebruikt moeten worden voor wind. 'Dat is wel erg veel. Je zult verbinding moeten zoeken.'
Zo heeft TNO al het North Sea Energy programma opgetuigd. Bedrijven, brancheverenigingen, onderzoeksinstellingen en maatschappelijke organisaties willen met dat programma 'de energietransitie op de Noordzee versnellen', aldus TNO.

De World Economic Council becijferde dat er in de overgang van fossiele naar groene energie tussen de € 200 mrd en € 300 mrd te verdienen is aan de Noordzee. Deels is dat windenergie. Maar ook de ontmanteling van de bestaande infrastructuur voor gas en olie op de Noordzee vertegenwoordigt een markt van tientallen miljarden. Daarnaast zouden oude gasvelden gebruikt kunnen worden om CO2 op te slaan.

Vooral de vissers zijn gekant tegen de windparken. Het gebied waar zij kunnen vissen slinkt, wanneer er windturbines komen te staan.
Meer helihavens, zo dicht mogelijk bij de windparken, zijn gunstig voor het snelle onderhoud verder op zee, zodat de turbines straks maximaal kunnen draaien. Want als de kolossale turbines straks stilstaan, dan kost dat veel geld. Heen en weer vliegen met een dure helikopter loont, zo beweert althans de luchthaven Den Helder.

Deel 2:

De trend van 'groot, groter, grootst' betekent dat bedrijven over enkele jaren mogelijk geld moeten meenemen wanneer ze een windpark willen bouwen. Minister Eric Wiebes wilde daar niet te veel op vooruit lopen, toen hij in Schiedam bekendmaakte dat Vattenfall de tender voor een 'subsidieloos windpark' had gewonnen. 'Het zou in de toekomst kunnen. Maar nu is het vooral belangrijk dat we een heleboel subsidie besparen.'
Vast staat dat de Noordzee een energiecentrale moet worden. En dat 2018 het laatste rustige jaar is. Over twee jaar moet het windpark bij Borssele operationeel zijn, volgend jaar beginnen op zee de eerste voorbereidingen voor de aanleg. Daarna moet er bijna jaarlijks een nieuw windpark worden opgeleverd. Zo wordt de Noordzee een van de grootste bouwplaatsen van Nederland. En niemand die het ziet.

World’s most powerful wind turbine successfully installed in Scottish waters

Power News - Published on Fri, 13 Apr 2018
Image Source: sbnn.co.uk

First deployment of the 11 innovative turbines for Vattenfall’s European Offshore Wind Deployment Centre marks treble project breakthrough for offshore wind industry. A hat-trick of offshore wind industry firsts has been achieved within a fortnight in North-east Scotland after the world’s most powerful single turbine was successfully installed on Monday, April 9 for Vattenfall’s ground-breaking European Offshore Wind Deployment Centre.

The turbine is the first of 11 to be deployed at the ground-breaking facility in Aberdeen Bay. In addition, Vattenfall has confirmed that it is one of two turbines that have been significantly enhanced with further internal power modes to generate more clean energy from the EOWDC. The two turbines have each increased from 8.4MW to 8.8MW and the installation represents the first time an 8.8 MW model has been deployed commercially in the offshore wind industry.

Together with the nine 8.4MW turbines, this substantially boosts the EOWDC’s output to 93.2MW. This allows the facility to produce the equivalent of more than 70% of Aberdeen’s domestic electricity demand and annually displace 134,128 tonnes of CO2.

The feat of engineering comes less than two weeks after the first of the EOWDC’s game-changing suction bucket jacket foundations was successfully installed. The EOWDC is the first offshore wind project to deploy the foundations at commercial scale and pairing them with the world’s most powerful turbines represents another industry first.

Gunnar Groebler, Vattenfall’s Head of Business Area Wind, said that “The turbines for the EOWDC, Scotland’s largest offshore wind test and demonstration facility, help secure Vattenfall’s vision to be fossil fuel free within one generation. The EOWDC, through its innovative approach to cost reduction and pioneering technologies, leads the industry drive towards generating clean and competitive wind energy power one that will reinforce Scotland’s global energy status.”

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

EOWDC project director at Vattenfall, Mr Adam Ezzamel said that “The first turbine installation is a significant achievement and credit to the diligence and engineering know-how of the project team and contractors. For it to be one of the 8.8MW models makes it an even more momentous moment because it further endorses the EOWDC as a world-class hub of offshore wind innovation. We are very excited by the cutting-edge technology deployed on all the turbines and it is remarkable that just one rotation of the blades can power the average UK home for a day.”

MHI Vestas Chief Operations Officer, Flemming Ougaard, said that “We are very pleased to have installed the first of 11 turbines at Aberdeen Bay. Our collaboration with Vattenfall not only provides clean wind energy for the UK, but also is an important opportunity for us to gain valuable experience with several different technologies. We look forward to the successful installation of the remaining turbines.”

The turbines are being transported from Esbjerg to Aberdeen by Swire Blue Ocean’s vessel, the Pacific Orca, where they will be lifted into position on the installed foundations. The Pacific Orca is believed to be the world’s largest wind farm installation vessel.

Mr Jean Morrison, Chair of Aberdeen Renewable Energy Group said that “The EOWDC is leading the way in terms of innovation for the offshore wind sector and will help enable the next generation of offshore wind. It’s a real coup for the region to have the world’s most powerful turbines on its doorstep and cements Aberdeen’s position as a major global energy city. It also will lead us to a greener future.”

Greek power launches tender for Crete link project

Reuters reported that Greece's power grid operator has launched an international open tender for a project linking the island of Crete to the mainland grid via undersea cables. The project linking Crete to the Peloponnese peninsula is part of a 2 billion euro (USD 2.5 billion), 10-year investment plan to connect some of Greece's islands to the mainland.

The tender, via an e-auction, will be awarded to "the most economically advantageous offer, based solely on the lowest price.”

The Crete link is expected to be completed by 2020 and is budgeted to cost 324 million euros, the ministry said. Crete will also be connected to Athens in a later phase.

Power production on Crete, the largest of the Greek islands, is currently provided by three oil-fired plants that must be shut down to comply with a European Union directive.

Energy Minister George Stathakis said the project would contribute to the "drastic reduction" of electricity costs, improve Crete's ecological footprint and lead to 215 million euros in annual savings, mainly through lower service charges.

State-controlled grid operator ADMIE was spun off last year from power utility Public Power Corp under Greece's international bailout. China's State Grid, the world's biggest utility, bought a 24 percent stake.

UK wind turbines spinning to record levels in early 2018

Climate action Programme reported that energy data for the first three months of 2018 have shown that wind energy is the UK’s star performer, having rewritten records across the board. Energy consultancy, Enappsys, compiled the official National Grid figures, which show wind turbines reaching new heights for daily, weekly, monthly, and quarterly output.

Wind power produced a quarterly high of 15.8 terawatt hours, a 39% increase on the same period last year. Windy conditions and new capacity helped push all renewable production to an all-time high of 25TWh, which represents 29% of all Great Britain’s power needs over the period.

By contrast, coal-fired power plants continued their decline and generated 9.4% of power; gas remained in pole position with 37.3%.

Early reports in March had concluded that the UK’s spell of inclement weather, dubbed the Beast from the East, had helped it provide high levels of renewable production. These latest findings show windy conditions have persisted throughout the early months of the year.

The latest data also confirms recent data that showed Scotland had a record-breaking start to the year for onshore wind generation.

Enappsys director Paul Verrill said that “The performance of renewables highlights just how important this electricity source and particularly wind has become to Britain’s power mix.”

The company’s quarterly report also concludes that: “With offshore wind farms now being a very cheap and relatively uncontroversial source of additional renewables generation, these levels of wind generation are expected to continue to rise, with additional generation also set to be released once the Western Link (subsea cable) becomes operational.”

Voltalia launch the construction of the Echauffour wind plant

Voltalia an international player in renewable energies announced the beginning of the construction of the Echauffour wind power plant (10 MW) in Normandy. Located in Echauffour in the Orne department (61), the Echauffour power plant is Voltalia’s first wind farm in Normandy, a region benefitting from the second best wind potential of the country, after Brittany. Equipped with wind turbines provided by Senvion, this project will be built and operated by Voltalia. It will benefit from long-term revenues secured for 15 years, under the contract for difference1 scheme.

This project falls within the local energy transition policy. As part of the “Perche / Pays d’Ouche” regional wind plan, the Echauffour plant will help reach the region’s installed capacity target of 70 to 100 MW by 2020.

The commissioning of the power plant is expected in the first semester of 2019 and its electricity production should cover the consumption of circa 10,000 households.

Siemens Gamesa inks new agreement for four wind farms in Spain

Siemens Gamesa Renewable Energy has entered into new agreements with Gas Natural Fenosa Renovables for the supply of 166 MW at four wind farm developments in Spain. These projects fall under the scope of the renewable capacity allocated to the Spanish utility as part of the auction held last May.

Specifically, Siemens Gamesa will commission a total of 48 of one of its most popular turbines, the SG 3.4-132, thus installing 166 MW of capacity. The company will also operate and maintain these four wind farms, which are due to be commissioned in mid-2019, for three years.

The blades for these turbines will be made at the Aoiz factory (Navarre, Spain) and the Tangier factory (Morocco), while the nacelles will be produced at the Ágreda facility (Soria, Spain).

Siemens Gamesa's relationship with Gas Natural Fenosa dates back to 1997, since which time the company has supplied the Spanish utility with more than 670 MW, most of which in Spain and Mexico.

These new orders reinforce the company's leadership position in Spain, where Siemens Gamesa is the number-one OEM, having installed nearly 55% of the country's total installed base, which is equivalent to over 12,500 turbines nationwide. In addition, the company services over 7,500 MW, which is roughly one-third of Spain's installed fleet.

Er is geen draagvlak voor linkse wensdromen. Liever geen verplichtingen, verboden of boetes maar stimulansen. Er zijn zat alternatieve mogelijkheden. Er komt terecht een onderzoek.

De keuze van investeerders is begrijpelijk. Maar Nederland is groter dan alleen de driehoek Stadskanaal-Musselkanaal-Gasselte. De zon schijnt niet alleen daar.

Het land heeft ordentelijke energietransitie nodig en dat betekent geen linkse dwingelandij.

Heeft niets met links te maken mag ik hopen, maar alles met gezond verstand.
De huishoudens moeten nu bloeden voor de energietransitie door de heffingen.
Energie die met name door het bedrijfsleven wordt gebruikt tegen spotgoedkope tarieven in vergelijking met huishoudens.
Datzelfde bedrijfsleven laten hun daken vooral leeg, tenzij heel veel subsidie kan worden verkregen.
Die zal het ruimtebeslag van al die zonneparken een worst zijn. Zij dragen niet of nauwelijks bij aan die verdomde parken.
Wij als burgers mogen deze vervuiling aanzien en ook nog eens een keer betalen.
Het is werkelijk van de pot gerukt!

ROERMOND (AFN) - Funderingsspecialist Sif gaat zogeheten monopiles leveren voor de offshore-windparken Borssele III en IV voor de Zeeuwse kust. De opdracht wordt toegekend door Van Oord dat een partner is bij de ontwikkeling van de windparken. Er werden geen concrete financiële details gemeld.

Sif levert alle 77 monopiles voor Borssele III en IV. De parken worden ontwikkeld door een consortium van Shell, Eneco, Van Oord en Mitsubishi en liggen circa 22 kilometer voor de Zeeuwse kust. De productie van de monopiles (68 kiloton) vindt plaats tussen begin juli tot december 2018. De windmolens worden geplaatst in water tot 38 meter diep en krijgen turbines van het Deense Vestas.

Sif had de opdracht al in het orderboek gezet als ,,exclusieve onderhandelingen'' en het is nu een vast contract geworden. Het totale orderboek voor 2018 staat nu op 183 kiloton.
