World’s largest offshore wind farm opens off northwest England

LONDON (Reuters) - The world’s largest offshore wind farm will open on Thursday off the northwest coast of England when Danish energy group Orsted (ORSTED.CO) unveils the Walney Extension project.
The wind farm has a capacity of 659 megawatts (MW), enough to power almost 600,000 homes, and overtakes the London Array off England’s east coast which has a capacity of 630 MW.
Walney Extension is made up of 87 turbines built by Siemens Gamesa (SGREN.MC) and MHI Vestas, and covers 145 square kilometers (55 square miles), which is equivalent to around 20,000 football pitches.
The
40 eight-megawatt MHI Vestas turbines being used stand 195 meters (213
yards) tall and are the largest wind turbines in operation globally.

Orsted said they have been optimized to generate as much as 8.25 MW each.
Matthew
Wright, Orsted UK managing director, told Reuters in an interview
Britain’s offshore success was due to a combination of strong wind
speeds and shallow waters in the North Sea and Irish Sea as well as
continued support from the government.
“For the last 10 years governments of all colors have supported renewable energy and offshore wind in the UK, leading to a thriving industry,” he said.
Britain is the world’s largest offshore wind market, hosting 36 percent of globally installed offshore wind capacity, data from the Global Wind Energy Council showed.
Walney Extension was among the first renewable projects to secure a so-called contract for difference (CFD) subsidy from the British government in 2014.
The contract guarantees it a minimum price for electricity of 150 pounds ($195) per megawatt hour (MWh) for 15 years.
Since this was awarded, the cost of offshore wind has fallen dramatically to a low of 57.50 pounds per MWh in the last auction held in 2017.
Blades for both sets of turbines were made at British factories, in Hull and the Isle of Wight, and Wright said the company was keen to use local facilities.
“Approximately 50 percent of the value of the project over its lifetime will have come from UK sources,” he said.
Walney Extension is a shared-ownership project between Orsted (50 percent) and two Danish pension funds - PFA and PKA (25 percent each).

全球規模最大海上風力發電站啟用

在英格蘭西北部對出海面，全球規模最大的海上風力發電站正式啟用，它的面積超過一百平方公里，可以滿足六十萬戶家庭的電力需要，標誌英國的電力供應之中，綠色能源的比例更進一步。
在英國坎布里亞郡離岸十九公里的海面，一個新落成的海上風力發電站在九月六日正式啟用。它的面積達一百四十五平方公里，接近兩個香港島那麼大，是全球最大的海上發電站。八十七座發電風車，總發電功率是六百五十九兆瓦，足以應付六十萬戶家庭的電力需求。發電站由丹麥一家能源公司興建，所有渦輪扇葉都在英國製造 (博主註: 渦輪分別是由西門子和丹麥維斯塔斯所造, 只有扇葉才是英國製造)。其中四十座發電風車每個高一百九十五米，是全球最高，發電站的運作及維修由二百五十名員工負責。
英國被視為歐洲之中，最適合發展風力發電的區域，而英國生產綠色能源的能力在全球排第六。二零一七年英國消耗的電力佔一成半來自風力發電，比重是歷來最高。而今年的第一季，英國的風力發電產量歷史性首次超越核能發電。隨著新的風力發電站啟用，英國對核能的依賴有望進一步降低。轉載自:
