1. Emergence of SEM positions
In the early 1960s, the significant growth in electricity consumption led to a rethinking of the distribution of electrical energy in large conurbations. Thus, in France, the 245 kV voltage, which until then had been used exclusively for transmission, gradually became a voltage for direct supply to distribution networks, in large conurbations or in areas close to them (cf. ).
