Introduction Despite significant socioeconomic development over the past decade, Bangladesh still faces major challenges to sustainable growth because of infrastructure deficiencies, including in the energy sector. The country has made considerable progress in increasing generation capacity to meet the growing demand for electricity to achieve its vision of becoming an upper middle-income country by 2031. Yet the sector still suffers from recurring power supply shortages, an increasing number of interruptions, and damaging voltage fluctuations. Transmission and distribution losses and inefficiencies are persistent problems afflicting Bangladesh and other developing economies in the region. Applying the latest technologies in energy transmission, such as high-temperature low-sag (HTLS) conductors and dynamic line rating, can help address these issues and improve supply-side energy efficiency and promote renewable energy development as well as cross-border power trade. Advances in technology also offer solutions for building the resilience of the electricity infrastructure to risks from climate change, natural hazards, malicious attacks, and human errors. High-Level Tech Solutions In Bangladesh, the Asian Development Bank (ADB) is supporting a project to expand transmission lines in Greater Dhaka and the western zone using high-level technology applications to increase efficiency and reduce carbon emissions as well as strengthen climate resilience. The project area covers Dhaka, Khulna, and Barishal, which are economic growth centers. Launched in 2019, the project is installing high-level advanced conductors, which were also used in the Southwest Transmission Grid Expansion project approved in 2018. These new conductors allow more power transfer at lower energy losses and have higher resilience to extreme weather events. The project will also introduce drone technology to improve safety and efficiency of operation and maintenance. The video above explains how high-temperature low-sag (HTLS) aluminum conductor composite core (ACCC) cable reduces thermal sag compared with the conventional aluminum conductor steel reinforced (ACSR) cable. It also talks about the advantages of deploying drones for the inspection of transmission lines to make the work safer, more efficient, and more cost-effective. Once the upgrading and expansion of the transmission network are completed, the improvements are expected to not only strengthen Bangladesh’s energy security but also boost the country’s capacity for more massive integration of renewable energy and increased cross-border power trade with neighboring countries.
