Integral structuring of the transaction of the first pilot project of transmission lines. The project considered the transmission infrastructure for the interconnection of the electric system of BC with the SIN through a link in the direct current between the Cucapah SE in the State of Baja California and the SE Seria in the State of Sonora. The interconnection is in direct current from a point that operates in a bipolar form with a capacity of 1,500 MQ, at a voltage level of 500 kV with an estimated length of 700 km. The Transmission Line also considers the construction of 2 converter stations of 1,500 MW with direct current transmission voltage of 500 kV, primary AC voltage level of 400 kV
