Electrical equipment for
Red Eléctrica De España substations in Peru

From 2017 to 2020, Red Eléctrica de España has been present in Perú at the departments of Arequipa, Moquegua, Tacna, Puno and Cusco through the companies Red Eléctrica Andina (REA), Red Eléctrica del Sur (REDESUR) and four electricity transmitters. It is responsible for designing, constructing and operating substations and high voltage lines in the Andean country.

Design, construction and operation

Equipment manufactured for this project includes:

  • 31 protection and control cabinets.
  • 27 auxiliary services panels
  • 58 distribution boxes. de circuitos.
  • 10 differential busbar protection cabinets.
  • 5 x CCS


Since 2016, Transmisora Eléctrica del Sur 3 has been the concessionary company for the design, construction, operation and maintenance of the 220 kV Montalvo-Los Héroes transmission line, as well as the expansion of the Montalvo (Moquegua) and Los Héroes (Tacna) substations. This line has a circuit length of 129 km and is scheduled to be operated commercially by 2019.

Part of the Montalvo substation to the Los Héroes substation with an altitude of 650 to 1,450 m.a.s.l., covering the departments of Moquegua and Tacna. The equipment manufactured for this project includes:

  • 12 protection and control cabinets.
  • 15 auxiliary services panels
  • 30 distribution boxes.
  • 2 differential busbar protection cabinets.

Construction of

REDESUR is the company that operates the electrical system in southern Perú under concession (mainly in the regions of Arequipa, Moquegua, Tacna and Puno). Among its tasks was theconstruction of the Chilota substation, the equipment requested being the following:

  • 10 Protection & Control Cabinets.
  • 18 Auxiliary services panels
  • 19 Circuit Centralization boxes.

Throughout its history, multiple earthquakes have affected Peru, which is probably the most damaging type of natural catastrophe for the country, not only because of the seismic movement itself, but also because of the collateral events that entail, as are the tidal waves. From Montrel we have been in charge of the manufacture and supply of electrical equipment for REE and that serve for the maintenance and operation of substations in complex environments or with the possibility of earthquakes. For this we have carried out the seismic certification according to the IEEE-693 of 2005 standard of our supplied equipment, thus guaranteeing the viability and durability of these.

Through their transport network, these companies collect the electrical energy generated by the production plants. These supplies sthey have amounted to more than six million euros since 2017.
