EDF has a little trouble getting through the winter

[sicetaitsimple]

Should not install heat pump rigorously!

???? Source?

[Christophe]

Is there a need for a source for the evidence? The water gets wet you know?

Replacing an oil or gas boiler with a heat pump under the false cover of free and green energy will inevitably increase electricity consumption! Heat pumps sold for fortunes of 20 to 40 k € or 10 times more than a renewal of a boiler ... green is never expensive enough, especially when it is false green !!

There are undoubtedly statistics on the PAC installations which must be lying around ... if you doubt my assertion ...

I must be lucky for the shots

...

The "real" green does not exist, except marginally and because it remains not generalized.

I have no doubts, I just ask for a statement to be sourced. You reproached me enough, including for today's information available everywhere.

That said, it seems to me (to be verified) that the peak winter power is rather down since the historic peak of more than 100GW recorded in 2012.

Hi,

It seems to me (to be verified) that the winter peak power is rather down since the historic peak of more than 100GW recorded in 2012.

This is not necessarily to be blamed solely on the energy production method or heating consuming appliances ...

but maybe also (and especially ...?) The temperature of the time ... in February 2012, it seems to me that it was peeling quite a bit.

Certainly ... It is not said that we do not find periods of very intense cold one winter or another.
At the same time, and this is what I wanted to say, low consumption light bulbs have been generalized, household appliances such as refrigerators or washing machines are more and more "low consumption", ....
In short, it's a whole, of course the development of heat pumps (and electric vehicles) will lead to an increase in electricity consumption, all other things being equal, and it will be necessary to put in front of the means of production which are going well . If it's just power 200 or 300 hours a year, it won't be a big deal.

Reactors shut down, electrical vigilance set in January

AFP Published on Dec. 30

The supply of electricity to France will be the subject of a heightened level of vigilance in January because of a lower availability of the nuclear fleet, according to the network manager.

The weather forecasts, however, moderate fears about food security: the occurrence of severe and lasting cold episodes, sources of consumption peaks, "appears very unlikely" during the first half of the month and beyond. "unlikely" (with however a higher degree of uncertainty), notes RTE Thursday in an analysis note on the balance between supply and demand.

However, the manager of high voltage lines has raised its "level of vigilance", and plans a series of measures in a context of European energy crisis and tensions on supply in France.

The country, which draws 70% of its current from the atom, is suffering from reduced availability of its nuclear fleet linked to a busy maintenance schedule, furthermore disrupted by the confinements of 2020. EDF also had to shut down in mid-December two reactors at Chooz (Ardennes) and extend the Civaux (Vienne) shutdown, after the detection of faults on safety circuits.

RTE thus assesses the forecast availability between 43 and 51 gigawatts for January (out of a total nuclear production capacity of 61 GW), ie "the lowest level ever reached for the nuclear fleet at this time of the year".

The year 2022 should start with 12 reactors shut down (out of 56), before an improvement during the month, except for contingencies. EDF had up to 17 in mid-December.

The government, for its part, has asked to take measures to improve the security of supply in the short term, and an independent audit on industrial control and the optimization of reactor outages (with a progress report expected by mid-March).

The electrician announced that he had "re-optimized" his maintenance schedule, which should be felt from February only, said Thomas Veyrenc, executive director of RTE, in charge of the Strategy, forecasting and evaluation division.

- "Controlled cuts" -

As for electricity consumption, the rise in prices linked to the energy crisis in Europe did not lead to a marked decline in demand and RTE maintains its forecast of -1% to -2% compared to the period preceding the health crisis.

This is how France, traditionally an exporter of electricity, has had to import electricity since November, at levels sometimes close to maximum technical capacities, such as between December 20 and 22.

Today the country has satisfactory hydraulic stocks. RTE also recalls the existence of the last two coal-fired power stations, at Saint-Avold and Cordemais: these units could be used at the start of winter, but their legal limits of use would make them fairly quickly unavailable.

In this tense context, RTE has a range of exceptional measures for the rest of the winter. Firstly, the interruption of large industrial consumers and a slight drop in voltage on the networks, "probable" in the event of extreme cold (of the order of 4 ° C below seasonal norms) or of low wind power production in Europe.

"As a last resort", in the event of lasting cold coupled with the absence of wind for wind power, or of further degradation of capacities, particularly nuclear, RTE could also "potentially resort to targeted cuts of consumers", he warns. .

These "momentary cuts are in no way a blackout, but operations that we control, implemented with distributors and State administrations", insists Jean-Paul Roubin, RTE's director of operations, referring to a measure extremely rare, the last example of which dates back to the 1990s in a context of social movement.

A "localized load shedding, limited to two consecutive hours", and sparing sensitive consumers, in particular the health sector, specifies RTE.

RTE will publish an updated diagnostic for February at the end of January. In the meantime, consumers can follow the situation in real time on the Ecowatt website (www.monecowatt.fr).

Our policies are walking on their heads, but rest assured, other countries are doing the same

Why the risk of power cuts?

The electricity shortages that are looming for France have a known cause: the
irresponsible reduction in the margins of the electrical system due to the energy policy
leaders of this country

The past weeks have shown how justified these warnings are and how increasingly fragile our electricity supply situation is. This state of affairs is not linked to exceptional circumstances, but to a series of decisions devoid of any forward-looking vision.

In 2020, the government did not find anything better, while boasting about it, than to close the Fessenheim nuclear power plant in perfect working order and which produced 1 MW of carbon-free electricity. Politician, absurd and irresponsible decision initiated by the former President of the Republic and implemented by his current successor. However, from the summer and autumn of 800, these 2020 MW ran out and led to the re-ignition of the coal-fired power stations, a totally unusual situation at these times of the year. But above all, these 1 MW are sorely lacking during the winter period of high demand, as at present.

This closure also came after that of more than 7 MW of large oil and coal-fired power stations since 000. Admittedly, they emitted CO2015, but since they operated for a very short time each year, only to pass peak consumption the most critical winter events, their climatic impact was very limited. On the other hand, their contribution in power during these consumption peaks brought an essential security of electricity supply.

In summary, we have massively eliminated 9 MW of controllable means of production, that is to say greatly reduced the margins of the electricity system, without the Presidents of RTE in office, the current one and his predecessor, responsible for by law, of the country's electricity production-consumption balance, do not warn of the real dangers of these suppressions other than through soothing press releases certainly invoking a "reduction of the safety margins" of the electricity system in the years to come. come, but only calling for simple "vigilance".
