bonjour à tous
Similar situation in EU, USA, elsewhere.
electric generation, transmission and distribution systems were designed and installed decades or even a century ago.
The radical changes in generation and load over space and time, require total review and redesign of the sources, grid, controllers and load management.
Nowadays the utilities are controlled by laws, regulatory compliance and politicians.
Most of the experienced power and nuclear engineers are long retired.
Finally the old line manufacturers, GE, Westinghouse, Brown Boveri, ABB are fully booked years out or have off-shored manufacture to China.
Thus the issues are long, deep and very wide ranging.
Suggest a natural gas/ propane permanent install backup generator for 25 kva or less eg your house or small firms
Just the ramblings of an old retired EE, 1968
Bon courage
