London Array Offshore Wind Farm

Youtube text: “uploaded 25 nov 2010 – With its 175 turbines, the London Array OWF in UK will be the largest offshore wind farm in the world when completed. The monopile foundations are designed by COWI-IMS JV. The foundations support a 3.6 MW Siemens WTG, and the OWF will produce a total of 630 MW. Contractor is ABJV and developer is London Array Ltd.

London Array Wind Farm

London Array project has begun producing electricity. When finished this offshore wind farm will be the largest in the world. Location: 12 miles off the coasts of Kent and Essex in the Thames Estuary. Capacity after completion first phase: 470,000 households. Start project: March 2011. Wind turbines installed to date: 151 or 175 at the end of phase one (630 MW). Phase two (if started) will add another 240 MW. Ownership: E.ON 30%, Abu Dhabi–based Masdar 20%, Dong Energy 50%. E.ON believes that the costs of offshore wind energy can be reduced with by 40% by 2015.

Shell Plans Return to UK Offshore Wind

Royal Dutch Shell says it is considering bidding for rights to develop offshore wind farms in UK waters as the British-Dutch oil and gas giant seeks to re-enter the nation’s sector after a 10-year absence.

Dorine Bosman, Shell’s wind chief, said the company was interested in seabed leases due to be awarded during 2019 by the Crown Estate, which controls Britain’s coast. The Dutch-based firm left the UK offshore wind sector when it sold its stake in the London Array project 10 years ago.

A global pioneer in the field, the UK was one of the key offshore wind markets Shell wanted to enter, she said. The oil major says it is investing US$2 billion a year in developing “new energies” or low-carbon power.

Shell co-owns a minor offshore wind farm in the Netherlands and a larger Dutch project which is under construction. In December it spent US$175 million entering the tiny US market, acquiring the rights to New Jersey and Massachusetts seabed leases that could potentially generate 4.1 gigawatts of wind power.

Contracts Signed for 752 MW Offshore Wind of Dutch Coast

Ding-dong! The contracts to build the largest offshore windfarm in the world (surpassing London Array of 630 MW) are signed and the winners are DONG Energy of Denmark and its subcontractor Siemens-Gamesa. Together they will build the Borssele 1&2 wind offshore farms, 22 km off the coast of the Netherlands, together 752 MW. New is that 8 MW turbines will be installed, 94 of them. The windpark should be operational by 2020.

Shell btw is to build Borssele 3&4, another 680 MW.

By 2023 4.5 GW is planned to be installed in the Dutch part of the North Sea.

Longer term Dutch offshore wind plans: 17 GW

Engineering World – Offshore Wind Power

Youtube text:

A wind farm is a group of wind turbines in the same location used to produce electricity. A large wind farm may consist of several hundred individual wind turbines and cover an extended area of hundreds of square miles, but the land between the turbines may be used for agricultural or other purposes. A wind farm can also be located offshore.

Many of the largest operational onshore wind farms are located in Germany, China and the United States. For example, the largest wind farm in the world, Gansu Wind Farm in China has a capacity of over 6,000 MW of power in 2012[1] with a goal of 20,000 MW by 2020. The Muppandal Wind farm in Tamil Nadu, India is the largest onshore wind farm outside of China, with a capacity of 1,500 MW. As of April 2013, the 630 MW London Array in the UK is the largest offshore wind farm in the world, followed by the 504 MW Greater Gabbard wind farm in the UK.

Gargantuan 32 GW Wind Projects Underway in the UK

doggerbank_wind[source]
The carbon fuel era began in Great-Britain and maybe that was the reason that until now the British were lagging behind with the introduction of renewable energy. But that could change soon as very ambitious projects are underway in the realm of offshore windfarming. Windfarm developers have acquired licenses in order to develop potentially up to 32 GW of wind power, about twice the power consumption of the Netherlands, eclipsing anything we have seen so far. The largest area would be situated at the Doggerbank (13 GW), to be developed by Forewind. The UK has the biggest wind resource in Europe. The London Array wind project currently under construction already is the largest project to date (630 MW). The Doggerbank project will dwarf anything we have seen so far.

European Wind Potential

Map shows average wind speed at hub height (80 m onshore, 100 m offshore)

It is obvious from the map that most potential for new wind-energy is located in the North-Sea. Exploitation to that effect is underway, driven by the UK, Germany, the Netherlands and Denmark.
