Is it worth installing 41 GW or 54 GW in 2030 in France?
Researchers have tried to calculate what the 12.5 GW gap foreseen as an objective in the Multiannual Energy Programme for 2030 corresponds to.
This provides a low option (41.5 GW) and a high option (54 GW) in French PV installations.
According to France Territoire Solaire (FTS), this difference in installed power makes it possible to produce an additional 14.2 TWh. This additional production replaces half of nuclear production (6.88 TWh), i.e. less than 2% of French nuclear production, and half (7.4 TWh) of thermal production, both in France (11%) and in Europe (89%).
"Therefore, if the high option of the EPP is reached, the production of decarbonated energy is increased by 7.4 TWh compared to the low option", FTS underlines. "The production of carbon-free electricity could be further increased (up to 14.2 TWh) if the increase in capacity is achieved.s PV capacity was accompanied by the deployment of additional flexibilities, such as electricity storage or conversion to hydrogen. Decarbonised energy production would increase if there was a change in consumption and if new mobility, industrial production or construction uses in the building sector were used beyond the targets given by the EPP or by readjusting the maintenance plan of nuclear power plants. »
Analysts say: the reduction in CO2 emissions amounts to "238 g of CO2 per kWh. This is the result of the 270 g of CO2 / kWh reduction in emissions avoided by the additional photovoltaic production on the one hand, and on the other hand the use of 32 g of CO2 / kWh required to manufacture and install the PV systems. »
Thus, by increasing the installed solar capacity in France by 12.5 GW which produces 14.2 TWh annually, a saving of nearly 3.4 million tonnes of CO2 per year in Europe by 2030 could be made.
The increase in solar production therefore plays an effective role in decarbonising the electricity mix.

NDLR By dint of wanting to prove everything, we only follow its logic, that of CO2without specifying how much it costs and how to really achieve it. In the end, a figure of 3.4 million tons of CO2 avoided is given, without putting this figure in relation to France's annual production, which would allow us to put the proposal into perspective or to see the interest of the proposal.
