El Salvador Distribution Box Renovation Plan
El Salvador is modernizing its electricity distribution infrastructure through eco-efficient technologies, digital solutions, and upgraded distribution boxes to enhance reliability and sustainability.
Overview of the Renovation Plan
The renovation plan in El Salvador focuses on modernizing the electricity distribution network to meet growing energy demands while improving efficiency and environmental sustainability. DELSUR, a leading electricity distributor serving over 450,000 users in central and southern regions, has partnered with Hitachi Energy to implement eco-efficient transformers and digital solutions that enhance grid performance and operational reliability . The initiative aims to reduce environmental impact, improve asset management, and ensure long-term stability of the power supply.
Distribution Box Upgrades
A key component of the renovation involves upgrading distribution boxes (DBs) and fiber optic distribution boxes (FDBs) to improve safety, accessibility, and operational efficiency. Modern DBs are designed with high-quality engineering plastics, compact structures, and standardized dimensions (e.g., 400mm x 500mm x 200mm) suitable for outdoor installation . These upgrades facilitate easier maintenance, reduce the risk of overheating or electrical faults, and support integration with digital monitoring systems.
Digital and Eco-Efficient Technologies
The plan incorporates digital solutions to enhance decision-making through data-driven insights, enabling predictive maintenance and real-time monitoring of the grid . Additionally, EconiQ™ power transformers filled with natural esters replace conventional mineral oil, offering environmental benefits such as decarbonization, ecosystem protection, and improved safety for personnel . These technologies collectively contribute to a more resilient and sustainable electricity network.
Regional Implementation
The renovation covers multiple regions through different distribution operators:
- DELSUR: Central and southern regions
- AES CAESS: Chalatenango, Cuscatlán, Cabañas, and northern San Salvador
- AES CLESA: Western departments including Santa Ana, Sonsonate, Ahuachapán, and parts of La Libertad
- AES EEO and DEUSEM: Eastern regions including San Miguel, Morazán, La Unión, San Vicente, and Usulután This regional approach ensures that modernization efforts are coordinated across the country, improving overall grid reliability and service quality.
Expected Outcomes
The renovation plan is expected to:
- Enhance grid reliability and reduce outages
- Improve operational efficiency and reduce maintenance costs
- Support environmental sustainability through eco-efficient equipment
- Enable digital monitoring for proactive management of the distribution network By combining infrastructure upgrades with digital and eco-friendly technologies, El Salvador aims to create a modern, resilient, and sustainable electricity distribution system capable of meeting future energy demands .
