Interconexión Electrica S A E S P : ISA DELIVERS THE MOST IMPORTANT ENERGY INFRASTRUCTURE PROJECT IN PERU IN THE LAST 6 YEARS

• The work, inaugurated with the presence of the president of Peru, Dina Boluarte, will benefit more than 12 million Peruvians and will be key to making progress in the regional energy integration.

• In addition, the project promotes the energy transition, as it strengthens the network to extend future international interconnections to Ecuador, Colombia, Brazil, Chile, and Bolivia.

• The delivery of the project is a historic event in the electrical evolution of Peru.

ISA, through its company in Peru, ISA Consorcio Transmantaro (ISA CTM), inaugurated the transmission project "Mantaro - Nueva Yanango - Carapongo 500kV connection and Associated Substations (COYA)." The work, with an execution term of approximately five years, will generate progress and development for more than 12 million Peruvians in the Lima, Junín, and Huancavelica regions. This energy infrastructure project, considered the most important in the last six years in Peru, is key to advancing the acceleration of the energy transition and strengthening of the network in order to extend future national connections and international interconnections with neighboring countries.

COYA marks a very important milestone in Peru, as it is a response to the growing domestic and industrial demand in the regions, which will allow us to create more development opportunities in the different areas of the interior.

"This long-awaited work, which today ISA CTM makes a reality, will help us close gaps in access to safe, quality electric power in the capital and central area of the country. We are happy to know that we promote greater access to energy, thereby improving the quality of life of people," said the President of Peru, Dina Boluarte, after calling for "unlocking more projects in order to make private investment viable for the benefit of the people."

For his part, the Minister of Energy and Mines, Oscar Vera, said that "the work done by ISA CTM was achieved thanks to the joint and coordinated efforts between the central government and regional and local authorities, which means that it is feasible to add synergies between the public and private sectors to generate progress in the country."

The CEO of ISA CTM, Cristian Remolina, said that "this project is one of the most relevant of the company's portfolio, as it is part of our long-term vision for the 500 kV network of the National Interconnected Energy System (SEIN), which represents a great effort for the company and its strategic allies."

The inaugural ceremony took place at the Campas substation, located in the department of Junín. Thanks to this project, it will be possible to transfer surplus generation from the Mantaro area to Lima due to increased generation in the southern area (RER and southern gas pipeline).

"It is important to mention that the transmission project will favor transmission from future renewable energy sources (RER) that are planned to be installed in the north and center of the SEIN; it will also leverage the connection of new generation projects, benefitting more territories," emphasized Remolina during the inauguration ceremony.

Construction challenges

The implementation of this project represents a technical and logistical challenge for ISA CTM and its strategic partners due to the complexity of the operation and geographical conditions. This is why COYA is making history in the evolution of electric power in Peru, as it required the installation of 785 towers, many of them at more than 4,914 meters above sea level (m.a.s.l.), the highest being 108 meters high, which required the installation of 25,300 tons of structure along the line that runs through nine Peruvian provinces.

During the development of the COYA project, more than USD 290 million was invested to guarantee the expansion and construction of its substations and transmission lines. This is in addition to all the logistics involved in the execution of the works, which required more than 11,000 man-hours.

The relevance of the COYA project lies in its long-term projection regarding the growth of the SEIN's 500 kV transmission network. This will allow for the strengthening of the 500 kV transmission network that will make possible the connection of new lines of the Transmission Plan.
