Bangladesh has reached a major milestone in its nuclear energy journey as the transmission line of the first unit of the Rooppur Nuclear Power Plant (RNPP) has been successfully commissioned at full capacity. With this development, electricity from the country’s first nuclear power facility is now ready for transmission into the national grid.
The milestone was achieved at 3:30 PM on Monday, June 2, when the 400 kV Rooppur-Gopalganj transmission line officially went online. This line spans approximately 158 kilometers and includes 414 towers, linking the Rooppur plant to the Gopalganj substation.
According to the Power Grid Company of Bangladesh (PGCB), the new line completes a trio of high-capacity transmission connections from the RNPP. Previously, two other lines had been activated to support the physical startup of the plant’s first unit:
• The 230 kV Rooppur-Baghabari line, launched on June 30, 2022.
• The 400 kV Rooppur-Bogura line, launched on April 30, 2024.
Each of these three lines has a transmission capacity of 2,000 megawatts, ensuring robust and reliable energy flow from the plant to the grid.
PGCB Executive Engineer Enayet Karim confirmed the achievement, stating that the successful commissioning of the Rooppur-Gopalganj 400 kV transmission line marks a significant milestone in Bangladesh’s national power transmission infrastructure. The final work on the line was completed on May 29, solidifying the plant’s integration with the national electricity grid.
This progress paves the way for Bangladesh’s first nuclear-generated electricity to become a key component of the country’s power supply, reinforcing energy security and diversification in the long term.
