Hornsea 2, last born of giant projects at sea

The Hornsea 2 project consists of a 300 wind farm of 6 MW each, located about 90 km off the coast of Yorkshire (east of England). With a cumulative capacity of 1,8 GW, this park could become the most powerful offshore wind farm installed in the world in the next decade. According to SMartWind, a Danish subsidiary of Dong Energy that is carrying out this project, it could produce 8,76 TWh a year, the equivalent of the average electrical needs of 1,8 million British households (the vast majority of households in this country are heated by gas (1 )).

If the Hornsea 2 fleet reaches its expected production, its load factor would exceed 55%, compared with the 24,3% on average of the French wind farm in 2015 (only terrestrial), thanks to the powerful and regular winds of the North Sea. http://www.connaissancedesenergies.org/ ... uni-160818
The kw of wind power per household is an assumption that can be verified in the near future : Wink:

But I agree. Growth is a leap forward; we waste a lot. We destroy without hope of return. We are not the only ones on earth. We must think of the future; we must also think of others, they are billions and do not have the necessary while we wallow in the superfluous.
I think so sincerely and for a long time.

I want a strong increase in the energy tariff in France, a concrete and very effective measure, if not all wishful thinking (such as turning off devices on standby) only serve to make one's self aware.

Only (I explain one last time) you said: "... la first and best solution the other thing is to avoid waste when you know that all devices are idle ... "
I show you that this is neither the first nor the best, nor even a solution : it is a legend, very practical because it gives good conscience without effort.

I'm not asking you to make amends about it and say, "You're right, I did not know."
I'm asking you to understand that we were only talking about devices on standby. So do not lecture me saying that you have to see a little further than the tip of your nose.

I am sure that you, like me, want the consumer electricity tariff to join the German tariff, to make our modest contribution to the protection of our environment.

No need to wish, it will inevitably come with the exorbitant expenses of EDF to keep the nuclear fleet operational and that we must pass on the consumers, that is to say us.

Only (I explain one last time) you said: "... the first and best solution is to avoid waste when we know that all devices are idle ... "
I show you that this is not the first, the best, or even a solution: it is a legend, very practical because it gives good conscience without effort.

My wording was about waste, not the devices on standby which is just an example in the middle of everything else. Cutting what is not useful is just a matter of common sense, regardless of an ecological vision. Nobody lets the engine run on the sole pretext that in 1 hour or the next morning we will use it.

I am sure that you, like me, want the consumer electricity tariff to join the German tariff, [*] to make our modest contribution to the protection of our environment.

Selfishly, I obviously wish that the tariff is the lowest possible for all, including for the industrialists as the SNCF since the electricity is crucial for this company and thus on the price of the tickets. But ecologically, I am convinced that current and future rates (unless REs take precedence) can only increase sharply. But, as with tobacco, the increase of it affects the lowest income, not the most affluent, where it is only a small part and is not a deterrent.

[*] The German tariff with its nuclear stops, does not allow a real comparison.

Very few people know that the energy at the SNCF is very little (it is not wasted as much).
In 2015, 1053 M € on more than 30 000 M € of expenses, ie some 3%; very weak influence on ticket prices.

[*] The German tariff with its nuclear stops, does not allow a real comparison.

Sure that the Germans made a blunder with their energiewende; let's talk about the Danish tariff then. Very early in the Danes; kWh a bit expensive (0,304 € / kWh).

Start of dismantling of the world's first offshore wind farm

Published 17 / 03 / 2017

After 26 years of operation, the Danish energy company Dong started the dismantling of the Vindeby wind farm, the first offshore wind farm in the world, completed in 1991. The announcement of the operation was made in February 2016.

The world's first offshore wind farm is withdrawing

16 March 2017

Vindeby OWF decommissioningDONG Energy has decided to withdraw "Vindeby", the world's first offshore wind farm, which 25 years ago marked the birth of the offshore wind industry. Vindeby Offshore Wind Farm, consisting of 11 offshore wind turbines, was connected to the grid in 1991.
The blades, basket and tower will be dismantled and taken down individually by a mobile crane on board a jack-up vessel. The concrete foundations will be broken down by hydraulic demolition shears, and collected afterwards.

All wind turbine components and foundations will be sent onshore to Nyborg Harbor where the components will be reused as much as possible for other wind turbines. Some of the blades will become part of a research project at DTU Risø while others will be successful in a new noise barrier concept.
One wind turbine will also be part of the exhibition at 'Energimuseet' (Danish Museum of Energy). Components that are not immediately reusable and will be transported to a certified recovery company. During its entire lifetime, Vindeby Offshore Wind Farm has produced 243GWh of power. The turbines for Vindeby Offshore Wind Farm were supplied by Energi Bonus, now Siemens Wind Power, and the foundations were produced by MT Højgaard.

https://www.windtech-international.com/ ... s-retiring

https://en.wikipedia.org/wiki/Vindeby_O ... _Wind_Farm

the turbines were doing 450 kW!

The original government concession is for 25 years; from 1991 to 2016. In 2016, DONG Energy considered shutting down the wind farm and had become uneconomical. Vindeby was the first in a long line of wind farms in a downwards cost trend. [4] [12]

As of March 2017 the wind farm is under decommissioning after having produced a total of 243 GWh. [13]

Hello,
When I look at the load factor of these wind farms consisting of 6 MW off-short machines as well as the evolution curve (exponential) of installed power year after year.
When we know the waste in an infinity of domain of the everyday life and in the building in particular.
When one imagines the potential of development of the sector at the genesis of its existence and in particular in the field of storage ...
When I finally imagine a more sober way of life, I can not help but believe in an optimistic scenario of transitioning everything into renewable energy by the next generation ....
It's just a story of time ....

Still about Gemini Park:


Gemini: A giant park of 150 wind turbines off the Netherlands

One of the largest offshore wind farms in the world has been commissioned on the 8 May off the Netherlands. This park, called "Gemini", has an installed capacity of 600 MW and could produce, according to its operator, 2,6 TWh a year thanks to the "strongest and most regular winds (1) of the Dutch part of the sea North ". This level of production would imply a load factor of the park around 49,5% (2).

The Gemini Park is made up of 2 sets of 75 wind turbines each, located nearby (hence the name "Gemini" (3)). These 4 MW unit power wind turbines are supplied by the German Siemens group, which owns 20% of the shares of the consortium in charge of the Gemini fleet. The Canadian electrician Northland Power is the main player in this consortium (60% of the capital) which also associates the Dutch companies Van Oord and HVC (10% each).

The construction of the Gemini wind farm cost a total of nearly 2,8 billion, which is the largest financing ever for an offshore wind project according to the consortium (which has received the support of some 20 banks).

The Gemini fleet must contribute to the objective of the Netherlands to bring to 14% the share of renewable energies in its final energy consumption at the 2020 horizon (against 5,8% in 2015). At the end of 2016, the country had an installed 4,3 GW wind farm (including 1,2 GW offshore (4)). Wind power would have satisfied about 8,9% of Dutch electricity demand in 2016 according to GWEC.

The water depth in the area of ​​the Gemini wind farm approaches 28 at 36 meters. The nacelles of wind turbines peak at nearly 88,5 m above sea level. Here, the laying of foundations.
