The REDESUR transmission system, designed for 220 kV, 138 kV and 66 kV, passes through the regions of Arequipa, Moquegua, Tacna and Puno, from the coast to the mountains, though zones with different climates and altitudes, reaching a maximum elevation of 4,677 m.s.l. This transmission system is connected to the National Interconnected System (SINAC) at 220 kV at the Socabaya substation; at 138 kV at the Puno substation, and at 66 kV at the Los Héroes substation, allowing interconnection to the SINAC by the transmission systems of ENERSUR at 220 kV at the Moquegua substation, EGESUR and ELECTROSUR (on 31 May 2009, the new line went into service and a 66 kV cell was transferred from EGESUR to ELECTROSUR) at 66 kV at the Los Héroes substation and REP at 138 kV at the Puno substation.
