Phew, we will still have a controllable solution that produces little GHG, in addition to renewable energies.
Our EPR plants must still last 10 years maximum (see less) for the oldest (a large part of the park built in the years 70-80), it is urgent!
There is a downside to nuclear reasoning: as private non-subsidized solar costs less than the kWh cdiscount, people are going to equip themselves with self-consumption.
The non-subsidized corporate PV tariff reaches the level of the historical tariff for consumers in the 36 KVA - 500 KVA range. And so we will see companies and shopping centers covering their roofs and parking lots with PV.
Suddenly, the nuclear load factor will drop, and therefore the cost per kWh, which depends primarily on the load factor, will increase.
The next step is storage ... with new generation LFPs, we are currently under 100 € per kWh at 3500+ cycles.
By taking the minimum of 3500 cycles, that makes a storage cost excluding converters at 28 € per MWh (we are almost 200 € per MWh for individuals).
We know what follows: individuals and companies will equip themselves with PV + storage, the price of network kWh will increase and fuel this cycle.
We will end up with a few low-tech gas power stations that will run less than 1000 hours per year and billing in the 300 + € per MWh per hour or the centralized network will be called upon. EDF's current business model is dead. It's inevitable. The business model of centralized power generation is also financially dead.
I just take the example of a private individual who places himself PV and his storage system on the ground:
- 10 kWp of PV -> 3000 €
- supports and inverters: 2000 €
- 10 kWh useful of new generation LFP batteries: 1300 € VAT, customs and shipping included
Let's assume that 50% of production is lost (with batteries, that's a lot ...), it's 5 MWh so 1000 € per year saved.
In the worst case, it pays for itself in 6 years.
In a company that buys HT equipment, it is profitable over 5 years, and therefore it sticks with the chart of accounts.
It is not only the Covid that lowers the annual production sold by EDF (the self-consumption figures are totally bogus because few people declare themselves on the Enedis site to pay the Turpe producer ... well let's see)
