Wind power: for or against the wind?

Thibr, you write:

what counts is the investment ratio Kwh recovered, which gives the cost price of Kwh produced

This is a reasoning, at least questionable, to be limited to a narrow accounting vision: on the one hand investment is an artificial datum based on loans calculated according to subsidized energy prices (in a certain way, a loan is almost decoupled from all reality) and, on the other hand, it does not take into account the waste of mineral resources and the negative externalities that they induce and which are very real, unlike the abstract value that puts them implemented.

For solar photovoltaic the average is around 15% ...

Wind: only 118 megawatts awarded in a national call for tenders


AFP 06 September 2018

Only 5 onshore wind farm projects, representing a capacity of 118 megawatts (MW), were awarded in the second tranche of a national tender, well below the originally stated target of 500 MW, according to the results released Thursday by the government.

The winners of this call for tenders, which concerned wind farms made up of at least 7 wind turbines, are the Canadian group Boralex, the Belgian Elicio, the British RES and the French Engie.

In detail, Boralex won two projects, one from 35,35 MW in the Auvergne-Rhône-Alpes region and one from 14 MW in the Hauts-de-France. In this same region, Elicio will build a fleet of 31,05 MW, while Engie-Green has won a fleet of 13,8 MW in the Grand-Est region and RES a fleet of 24 MW in Occitanie, according to the list published on the website of Ministry of Ecological and Solidarity Transition.

Among these projects, one consists of a "repowering" operation, ie replacement of wind turbines on an existing park, and another consists of an extension of a park.

On the other hand the government does not publish by the average price associated with these projects.

During the first phase, including twenty-two winners were announced in February it amounted to 65,40 euros per megawatt hour, when the last purchase price, defined in 2017 and involving only small plants, was set at 72 euros / MWh.

Before the publication of these results, the industry had warned that they would be disappointing. In question, a regulatory imbroglio that prevented many candidates from submitting their offers.

In December 2017, the Council of State canceled a decree, which blocked the issuance of the environmental authorization required for the submission of applications.

According to France Wind Energy (FEE), which brings together companies in the sector, 3.000 MW under investigation have been frozen, and 2.000 MW that had been authorized could be canceled at the slightest recourse.

In view of this situation, the third and fourth tranches of the call for tenders have been staggered by three months and the conditions of application have been relaxed.

The stakes are particularly important for the sector in view of the objectives set for 2018 (14.300 megawatts) and 2023 (21.800 at 23.300 megawatts).

At the end of the first half, the French fleet was close to 14.000 MW, but only the new 400 MW had been connected between the January 1er and the June 30.

In fact, this figure is actual production. 10% concerned RTE's forecast https://clients.rte-france.com/lang/fr/ ... iennes.jsp because they determine tomorrow's needs based on weather forecasts. They are therefore forced to waste fossil or nuclear energy to make up the difference.
It is therefore the forecast charge rate. If the balance sheet proves superior, so much the better, but if a coal or nuclear unit has been started for the occasion, there will have been unnecessary losses.

why mix the forecast at a time T and the average over the year?

[izentrop]

It's not mixing but distinguishing. Too bad, I did not manage to make the difference

Yes, well rather both ???

If consumers become more reasonable, the forecast could be revised downwards. RTE are obliged to take into account all eventualities without planning too generous, in order to limit losses, avoid load shedding and even less the "black out". For wind and solar, forecasts are reduced because of the uncertainty margin, which is normal, given the intermittency.

All this candlelight discussion is part of this article https://theconversation.com/50-de-nucle ... ible-98212 or RTE said to be able to ensure a winter like 2012 without load shedding if we reduce the nuclear 50%.
