Demonstrating that quality is the only synonym for trust, for 20 years there Transmission, a subsidiary of Ende Corporation, maintains its management systems certified by agencies internationally recognized for quality, environment, safety and health systems Occupational and social responsibility.

In that sense, during the 2023 management the following audits have been carried out:

Audit external to management systems from July 22 to 29: Through it, it has been achieved The renewal of quality management systems (ISO 9001: 2015), Environment (ISO 14001: 2015) and The maintenance of the Safety and Health Management System at work (ISO 45001: 2018).

External audit of social responsibility and verification of the sustainability report of the 29 of November to December 7: Through it, the maintenance of its certification in basis for the IQNET SR 10 standard and the 2022 sustainability report has been verified based on the new GRI standards (Global Reporting Initiative) in its exhaustive option.

As a result of the aforementioned audits, minor observations were identified, which will be treated Through the systematics established in the company, in compliance with the principle of continuous improvement. Ende transmission is a company that works under strict safety and quality standards to comply with the objective of guaranteeing the reliability of the supply of electricity to Bolivia.

UNICOM ENDE 05-01-2024.- The National Electricity Company (Ende Corporation), through Ende Transmission, replaced a high voltage tower that presented damage to its structure, caused by landslides, in a section of the Valle Hermoso electric line – Santiváñez, in the Ushpa Ushpa area of the Cochabamba department, thus guaranteeing an uninterrupted electricity supply.

Recent rains in the Ushpa – Ushpa sector caused the geological instability of a large area of land, causing cracks, local landslides, deformation and inclination of the strata of land, where the high voltage tower was located No. 10. This situation caused Deformations in main profiles and uprights of the structure, causing mechanical instability With a risk of collapse of the same, compromising the operation of the transmission line.

After a planning process, the state electricity made the decision to replace Tower No. 10 of immediate way.Structure assembly works, phase conductors and cables save the new structures and disassembly of the affected structure, were executed in 2 days, with The de -negized line.

To achieve this objective within the planned period, a large number of personnel moved and They used two high capacity cranes for assembly and disassembly of 44 meters of height.The execution of this activity was coordinated with ELFEC, the Alejo Calatayud subalcaldía, the USPHA USPHA and OTB Japan community, preventing possible risks, typical of this type of work.

The tower was substituted without incident registration and the transmission line was successfully replaced, guaranteeing in this way, the reliability of the electrical transmission network and providing tranquility to the population surrounding the structure, which was susceptible to the possible collapse of it and the interruption of the electric service.

The expansion of the national interconnected system (SIN) in our country, has diversified its composition, implementing renewable and non -renewable generation technologies, static compensation equipment and simple and double list of transmission;which increases the complexity of the operation in time real of the power system.This is how Ende Transmission, a subsidiary of Ende Corporation, in management 2023 executed a pilot project to implement a broad area monitor system (WAMS for its acronym in English), with cutting -edge technology that will help the real -time operation of the system of Power, increased the reliability and security of this.

The implemented system is composed of fasorial measurement units, satellite watches, Fasorial data concentrator and communications infrastructure;It also has a wide variety Of applications.As an initial stage, it monitors the stability of tension, permanent stability and transient stability;showing the measures obtained and calculated by different screens, the which provide the operator with the visibility of SIN.

The execution of the pilot project of the broad area monitoring system was successful, checking the contribution made by the system to the real -time operation of SIN;thus satisfying the growing demand of the sector, strengthening the availability of electric power supply for the benefit of families that inhabit the Bolivian territory.

Ende is a recognized company in the national and international electricity sector, by facing projects of Great scope with own engineering and cutting -edge technology, making constant update of Equipment and personnel to guarantee the reliability of the supply of electric power in Bolivia and consolidate as one of the safest and reliable systems in the region.

Within the annual programming and in the process of improving old facilities, there is transmission, Ende Corporation filial, performing the telecontrol system of the substation Beautiful valley.

One of the main objectives was to replace the remote terminal unit (RTU) with 15 years of antiquity;The replacement included telecontrol equipment, transducers, self -supporting boards, change of multipares and others.

Thanks to the hard work and performance of technical staff, the new and modern telecontrol system was in service on November 24, 2023. The implemented RTU is of the Schweitzer Model Axion Sel-2240, modular and with a variety of communication protocols available so that the system of control goes from being conventional to a hybrid control system, where the wiring can be maintained conventional, but also has the possibility of using IEC61850 communication protocols, DNP3 TCP, Modbus TCP, SNMP, Irig-B, HMI, among others.

To optimize the project architecture, analog transducers were replaced by digital, of that way the transfer of information to the SCADA system of analog signals of all the Transmission lines that converge in this substation.

This new and modern telecontrol system allows to meet the growing demand of the sector, thus strengthening the capacity and availability of electric power supply for the benefit of The families that inhabit the Bolivian territory.
