Video: Statoil's Dudgeon wind farm started production

Posted on 09/02/2017 Lemarin.fr

The Dudgeon wind farm, located 32 km off Norfolk, in the United Kingdom, is now operational.

The first turbine, installed in January, went into production successfully on February 7 by the park operator, Statoil, and its partners Masdar and Statkraft. It supplies electricity to nearly 6 British households.

Installation of the remaining 66 wind turbines, 6 megawatts each, is expected to be completed by the end of 2017. The park, with 402 MW of installed capacity, will then be able to supply electricity to more than 400 homes.

Statoil also said in early February that renewable energy, mainly offshore wind, would represent some 20% of its investments by 2030.

The park, with 402 MW of installed capacity, will then be able to supply electricity to more than 400 homes.

It makes them 1 kW of installed wind power per household, ie 200 to 300 W supplied per person and only in good wind; in calm weather they will only be entitled to a few watts to charge their mobile phone.
In France there are commonly 66 reliable GWs supplied in the winter evening for 66 million inhabitants, i.e. 1 kW per person and more than 2 kW per household, therefore twice as much and above all without failure.

When will we have some common sense in the figures concerning renewable energies (production and real costs)?

this is just the beginning.


Great Britain, which has 4.8 GW of offshore installed at the end of 2014, will increase to 23 GW in 2025.

UK to Remain Top Offshore Wind Power Market by 2025, with Capacity Exceeding 23 Gigawatts

July 22, 2015 evwind

The UK will remain the leading offshore wind power market globally by 2025, with its installed capacity increasing from 4.5 Gigawatts (GW) in 2014 to 23.2 GW by the end of the forecast period, representing an impressive Compound Annual Growth Rate (CAGR) of 30.5 %, says research and consulting firm GlobalData.
.......

The analyst concludes that the UK possesses the largest offshore wind resources in Europe, with the North and Irish Seas providing high-potential areas for offshore wind farm developers.

Siemens remained the UK's leading offshore wind market player in 2014, boasting a 76.2% share of the country's cumulative capacity. Vestas was a distant second, with 19.9%, followed by Senvion and Samsung with 3.8% and 0.2%, respectively.

Good for them.
"It is looking to reduce the cost to £ 100 per MWh", i.e. 117 euros / MWh.
Hopefully and without counting the costs of the back-up, supported by conventional energies.

But my post emphasized the ridiculous power per household: 300 watts in good winds, a few watts in calm weather.

An interesting project, without planning for the moment, but innovative: The realization of an artificial island in shallow water in the North Sea which would interconnect the wind fields and ensure conversion to direct current line between countries!

In this offshore wind farm, 630 MW installed produce 3 TWh and therefore 4762 MWh / year per MW installed https://fr.wikipedia.org/wiki/%C3%89oli ... 9cessaires
... Hair on the pile with the average consumption of a French household in 2015: 4 kWh. https://prix-elec.com/cours/consommation#moyenne

The classic mistake, wanted or not, is to reason in annual production.
The electricity produced at night cannot be stored to supply the peak consumption for the evening.
I had not even seen that 402 MW was the installed power, which will give 200 MW in very favorable winds, or 0,5 kW per household (and nothing at all in calm weather).

So try to live with a 0,5 kVA meter. The site you give indicates: "The most widespread electric meter power in France is 6 kVA".
It's still 12 times more (in good wind again).

You forget that

RTE's mission is to ensure, in real time, the balance between electricity supply and demand, drawing on the capacities and needs of electricity producers, traders, distributors, consumers industrial and railway companies. http://www.rte-france.com/

And they get there.

I don't forget anything at all.

I know the recognized skills of our managers, including RTE. For the moment They manage to neutralize the glaring failures of wind and solar, only because we still have few (18 GW wind + solar, 6% of total production in France). They compensate for these variations in production suffered by varying the production of gas, hydraulics, fuel oil and imports. This is not the subject.

What does this have to do with the huge brainwashing we're talking about: "402 MW installed which is enough for 400000 homes" ?
It makes 0,5 kVA per household in good wind: untenable. The most common power of the French fireplace is 6 kVA, 12 times more.

What is complicated to understand: the French take a 6 kVA subscription, more expensive than 3 kVA, because that at 3 kVA is insufficient (yet with a comfortable tolerance for overload, for the moment)?
Then 0,5 kW! And again, we must assume a load factor of 50%, infrequent.

We must also neglect the essential consumption associated with 400000 homes (a city comparable to Marseille, nothing!): Transport, hospitals, public lighting, water supply, shops (let's leave industries aside).

Simply ridiculous.

[izentrop]

You insist on instant consumption. Since RTE provides the interface, what matters is the actual production balance.
The load factor of individual wind turbines is not that great, that of large ones per 100 m is already better (load factor 24.5% real in 2015), but you quote

What does that have to do with the huge brainwashing we are talking about: "402 MW installed which is enough for 400000 homes"?

These are offshore wind turbines which are subject to a practically permanent wind at sea.

better performance of offshore wind, whose "load factor" would therefore be 43%. http://www.futura-sciences.com/planete/ ... nce-62765/

Which corresponds to the estimate given before.

We must also neglect the essential consumption associated with 400000 homes (a city comparable to Marseille, nothing!): Transport, hospitals, public lighting, water supply, shops (let's leave industries aside).

For that, nuclear power is not ready to be stopped. With the advent of runaway reactors, high reactivity and thorium, he still has a bright future ahead of him, but that's another subject.
