Electricity prices are rising all over Europe. The levels reached are historically high and France is not spared. We can then legitimately ask ourselves about the evolution of these prices in the long term.
This is a complex issue, as the factors are numerous and difficult to predict. First of all, we can cite gas and CO2 prices, or even temperature or demand. Currently, debates are also raging with regard to regulatory aspects.
It is therefore necessary to analyze a large number of parameters in order to draw perspectives. That is what we are going to try to do in this article.
Second, it is a hot topic, according to recent government announcements. Indeed, Jean Castex, the French Prime Minister, announced a 4% increase in regulated electricity sales tariffs (TRV). The situation is the same elsewhere in Europe, such as in Italy or Ireland.
To start, you have to remember the interconnection of European electrical systems. Europe is like a giant copper plate, allowing electrons to be transported across Europe.
Even if, in France, there are many nuclear power plants with low production costs, we are subject to variations in the prices of wholesale electricity markets. It is an interconnected market. For example, on the long-term markets, some French indices are built including German price forecasts. Les short-term markets (Intraday and Day Ahead) fluctuate according to what is happening elsewhere in Europe.
Beyond this interconnection of markets, there are structural factors that lead us to believe in a sustainable rise in electricity prices. The Merit Order operates in such a way that the market price reflects the cost of producing the last power plant called.
Thus, the costs of each of the producers are covered. However, there are still numerous state-of-the-art power plants in operation in Europe. These are coal-fired or gas-fired power plants, allowing To balance the network.
Network operators still rely on these often expensive power plants. Scheduled closures continue to be postponed (for example the Cordemais power plant in France). This contributes to maintaining electricity prices at high levels in the event of nuclear or renewable non-availability.
The IMF's growth projections continue to rise and expect a recovery of 6% for 2021 and 4.4% for 2022. Post-health crisis recovery is important. And, on the other hand, the level of demand affects the price.
The stronger the demand, the more the prices of gas, coal and therefore electricity increase. It is true that the health crisis can evolve unpredictably. However, as long as the situation remains stable and under control, it is certain that prices will respond to the rise.
The use of economic mechanisms such as ARENH can help reduce the effect of increases in electricity prices.
We can imagine that, if we increase the total ceiling (which is currently 100 TWh to €42/MWh), this can reduce the cost of supplying suppliers.
If countries decide to play the sovereignty card in the face of energy Europe, they can influence energy prices. It is certain that as the various elections approach, some candidates will make proposals in this direction.
However, this seems difficult to consider, because France is fully committed to the European Union.
As we have explained, what determines electricity prices are, at their core, the costs of producing electricity. We can imagine that the progression of renewables in the energy mix could make it possible to reduce average electricity production costs over the long term.
However, this is a somewhat truncated vision of reality. Indeed, the questions of intermittency and storing remain whole. As we saw recently in the projections made by RTE, even with a significant integration of renewable energies, if battery technologies do not evolve more quickly, the problem remains.
Since the post-Covid recovery, gas demand has increased sharply, in particular due to demand from Asian countries. This is one of the factors behind the recent rise in gas prices and therefore, ultimately, electricity prices.
Faced with this, the gas supply from Russia was insufficient and well below the usual exports. This situation has created numerous tensions on the energy markets in Europe.

It is difficult to say whether these export cuts are voluntary on the part of Russia, but it is putting pressure on all European markets.
We can therefore hope that, if on the one hand the demand is reduced and on the other hand the supply increases, then the prices will return to their usual levels. The growth (and therefore the Asian demand) expected in 2022 is in fact less important than 2021. Analysts agree that demand and therefore prices should be impacted. It remains to be seen whether other more important factors (CO2 price, nuclear availability, etc.) will not come to the fore.
It should be remembered that these conditions are entirely cyclical, and that it is likely that a combination of several of them will be needed to take effect.

The European Union recently launched a new European climate project. It is a set of measures aimed at reducing our greenhouse gas emissions. On a certain number of them, it is a question of carbon market (CO2).
The EU intends to use this tool to increase the price of CO2 by, in particular, gradually reducing quotas. This type of regulatory news adds complexity to long-term electricity price forecasts.
It is likely that this desire to reduce our emissions will push up electricity prices on wholesale markets. This is an element to be taken into account for long-term considerations.
A disruptive technological evolution could allow for a completely different development of the energy mix. For example, it is possible to see the evolution of the sector of batteries.
Indeed, it is the main element in the development of renewable technologies. If it is possible to manage The intermittency of renewable energies thanks to batteries, it will be entirely possible to consider energy mixes with an overwhelming share of renewable energy.
This could make it possible to gradually separate ourselves from fossil fuel power plants, the most expensive power plants (those with the highest production cost). We recall here that renewable energies (wind turbines and solar power plants) have an almost zero marginal cost of production. The cost of electricity is expected to be affected downwards.
We can recall that a third of the electricity bill consists of taxes and various contributions. Rather than counting on an evolution in research that will certainly take a long time, the fiscal instrument is the fastest instrument to put in place.
A good example is the freight rate contribution (CTA). It finances the specific rights relating to old-age insurance for IEG (Electrical and Gas Industries) staff. The State could decide to reduce these specific taxes or simply to reduce the VAT applied.

The subscribed power must be calculated according to the consumption profile and uses (heating, industrial processes, tertiary equipment). One fine analysis makes it possible to ensure the adequacy between real need and contract.
.png)
Tertiary companies must manage their energy costs while guaranteeing the comfort of users (offices, shops, services). Consumption is often linked to heating, air conditioning and lighting, which requires precise monitoring to avoid budgetary excesses.

Le transport (RTE) correspond aux "autoroutes" de l’électricité. Il s’agit de transporter de très grandes quantités d'énergie sur de longues distances, depuis les centrales de production (nucléaires, barrages, parcs éoliens offshore) vers les régions de consommation.
La distribution (Enedis) s'apparente aux "routes départementales" et aux rues. Elle récupère l'électricité à la sortie du réseau de transport pour la livrer directement chez le client final, en abaissant la tension pour qu'elle soit utilisable par vos appareils.

Oui, elle est considérée comme une énergie renouvelable à faibles émissions de gaz à effet de serre.
De plus, l'eau ne subit aucune transformation chimique durant le cycle de production et réintègre son milieu naturel en aval.
Cependant, la construction de barrages nécessite des mesures pour protéger les écosystèmes (débit minimum, passes à poissons).

L'abondance de production française tire les prix du marché de gros vers le bas.
En vertu du mécanisme de l'Ordre de Mérite (Merit Order), les centrales les moins coûteuses (nucléaire, renouvelables) couvrent la demande plus souvent, évinçant les centrales à gaz ou charbon plus onéreuses.
Cela multiplie les épisodes de prix bas, voire négatifs, sur le marché spot.

C'est le levier le plus rapide pour obtenir des résultats visibles. L'éclairage représente environ 40 % de la consommation d'électricité d'une commune.
Passer au LED avec pilotage intelligent permet de réduire la facture de 50 à 80 %, avec un retour sur investissement (ROI) rapide, souvent estimé à 2 ou 3 ans.

Ce record de 92,3 TWh s'explique par la conjonction de trois facteurs :
