renewable wind energy

London Array has been a resounding success. Since the completion of London Array almost 45% of all electricity produces for the capital comes from renewable resources, one way or another, be it solar, of the window farm itself. In case your reading this and wondering what is the London Array then let me give you a little background information.

The wind farm site is more around twelve miles off the Kent coast and is situated between Long Sand and Herne Bay. If we was to look out toward Clacton on Sea we would stand parallel is we was near Canterbury. This was the perfect position for a wind farm chosen, because of the depth of water not exceeding 30 metres and this was not in the way of any busy ports and shipping lanes.

The first part of the project was 175 Siemens window powered turbines and this was located on to different locations. The resulting power output at peak performance was in the region of 700,000 mega watts. If your familiar with structural engineering, you’ll understand just how well these have been built. Each one of these huge turbines has been built on a specially designed monopile. Please feel free to take a look at wiki in your unfamiliar with a monopile. The way the power is gathered and distributed from the London Array is quite simple, the turbines are all interlinked and have massive cabling running connecting and then power distributed to a substation in Graveney. All power is subsequently then directed to the London grid.


The implications for reduced carbon footprint are astonishing. The total CO2 emissions expected to be saved are close to a million tonnes. This is a staggering number that goes a long way toward helping London reduce its carbon emissions to levels which will significantly improve global warming. Along side key home energy saving plans such as sash window draught proofing in London and home insulation this initiative is giving London a brighter future.

Who owns the London Array?

Well sadly not London. The array has four significant investors. E. ON energy owns 30% of the entire project whilst La Caisse de dépôt et placement du Québec (“Caisse”) and Denmark-based DONG Energy. The brilliant news about these two companies is that they wish to reduce the cost of electric to less than a hundred euros per mega watt by 2020. Now this is going to significantly reduce electric bills unless the government doesn’t do enough to curb their profits. The smallest investor is Masdar is Abu Dhabi’s renewable energy company with a holding of just 20%. This company is known for it’s drive toward clean energy and I believe, how they were awarded an opportunity to bid on the London Array in the first place.

Is this really making a difference and not about corporate profit?

I can honestly say this really is helping our environment and technology combined with investment is resulting in new output records all the time. Just recently the array generated over 360k Mega Watts per hour of electricity. This is a staggering amount, capable of power half of London.
