"Over 70% work of the project has so far been completed," Director, International Market Management of TBEA's Ma told UNB.
He said the whole project will be completed and delivered to Dhaka Power Distribution Company Limited (DPDC) by the end of 2024.
Director Ma said TBEA is working under a US$1.65 billion project under which several subprojects are being implemented.
The project is the largest power cooperation project between the two governments of Bangladesh and China since establishing diplomatic ties between the two countries.
The implementation of the project will enable the power grid system to be of better quality and serve the government departments and people of Bangladesh, and better promote the social and economic development of Bangladesh, said the Chinese side.
TBEA, an international service provider of system solutions for the global energy industry dedicated to green and low-carbon development, with more than 24,000 employees from 24 countries, sees this project under the "Belt and Road Initiative" cooperation and development between China and Bangladesh.
Under the project, a total of 44 substations are being set up, Director Ma said.
Overhead cables of Hatirjheel Lake and the Dhanmondi residential area will be laid underground.
Bangladesh termed the project as a historic one for Dhaka as funding for this project was signed during Prime Minister Sheikh Hasina's visit to China, which Chinese President Xi Jinping witnessed.
