The investments comprise a USD350 million ADB loan, a USD7 million grant from the Japan Fund for the Joint Crediting Mechanism (JFJCM) to partially finance new high-technology energy efficient conductors, and a USD500,000 grant from the Republic of Korea e-Asia and Knowledge Partnership Fund (EAKPF) to promote socially inclusive growth with gender equality.
“Bangladesh has been experiencing impressive economic growth over the last decade, but to maintain and even accelerate this, more investments are needed for the power transmission network to meet growing electricity demand,” said ADB Senior Energy Specialist Mr. Aiming Zhou. “In support of this, the ADB project will make the power transmission system more efficient, reliable, and environmentally friendly.”

Despite its recent economic success, Bangladesh continues to face major challenges. A top priority of the government is to address infrastructure deficiencies, including modern and affordable energy services, which face recurring shortages and ever-rising demand. About 35 million people in the country are without access to electricity. Inadequate transmission lines and substation transformer capacities in the southern and western regions are the main contributors to transmission bottlenecks. At the same time, construction of new transmission lines has become more challenging because of the high population density and limited rights-of-way.
The Southwest Transmission Grid Expansion Project builds on ADB’s previous work in the Bangladesh power sector, including the recently approved Rupsha 800 megawatt Combines Cycle Power Plant in the southwest region, to address continuing deficiencies in the transmission system through providing more efficient power transfer to the load centers of the southern and western zones.
The project will develop a 126 kilometer (km)-long 230 kilovolt (kV) transmission line from Barisal to Faridpur; and a 104 km-long 400 kV transmission line from Bogra to Rohanpur, along with substations, transformers, and associated extensions and connections.
The new transmission lines will introduce to Bangladesh a new type of high temperature conductor to allow more power transfer at lower energy losses. These have less resistance to power flow, higher power transferring capacity, and operate more reliably in tropical weather. In addition, the use of these conductors also helps to minimize right-of-way requirements.
The project is also contributing to climate change mitigation, since the new conductors reduce carbon dioxide emissions compared to conventional transmission conductors that are used in Bangladesh. This climate change mitigation accounts for USD93 million of the investment, comprising USD86 million from the ADB loan and USD7 million from the JFJCM grant.
Under the EAKPF grant, the project will fund a scholarship program that will support women’s access to higher education and boost their job opportunities in the electricity industry.
The government will contribute USD174.5 million toward the $532 million total cost of the project, which is due for completion at the end of June 2023./.
