This lecture delves into the integrated energy infrastructure planning of Germany and France. Germany, with a population of 81.4 million, is the largest domestic market for electricity in Europe, accounting for about 40% of the total. On the other hand, France, with 67.2 million inhabitants, is the second domestic market and the leading exporter of electricity in Europe. The presentation covers various aspects such as electricity generation, renewable energy sources, market organization, electricity prices, and the gradual opening up of electricity production to competition in both countries.
