Aminbazar-Gopalganj 400 KV power transmission line came into operation crossing Padma River
After a delay of more than two years, finally the Aminbazar-Gopalganj 400 KV power transmission line came into operation crossing the Padma River.
“The line was commissioned successfully at 1:40 pm on December 15 (Thursday) from Gopalganj grid substation with 400 KV voltage”, the Power Grid Company of Bangladesh (PGCB) said in a Facebook post.
However, PGCB managing director Golam Kibria said that although the line was commissioned, electricity flow will not be given through this line.
"We've planned to flow electricity from next Saturday on test basis and then step by step it will be fully commissioned by gradually synchronising with all the systems”, he told UNB.

PGCB officials said that the full commissioning of the newly constructed line will facilitate electricity transmission from the two large power plants—1320 MW Payra and 1320 MW Rampal power plants—in the country’s southern region to Dhaka city.
Of these, the Payra power plant having two units, each 620 MW capacity, set up in joint venture with Chinese company, have already been commissioned. The first unit (620 MW capacity) of Rampal power plant is also being built in joint venture with an Indian company and it is expected to be commercially commissioned in March next year.
“If the electricity from these two plants can come to the capital city, it will play an important role to improve the power supply situation”, said a top official of the Power Division.

The government had undertaken the implementation of the Aminbazar-Gopalganj transmission line in 2016.
But due to construction of the Padma Bridge, works of tower installation in Padma River remained suspended until completion of the bridge construction. As a result, the project experienced a huge delay to complete.
The PGCB in the Facebook post mentioned that the newly constructed Aminbazar-Gopalganj 400 KV power transmission line has been successfully commissioned with charging power by the PGCB.
The length of the line from Gopalganj to Aminbazar grid substation is 82.5 km. Of which there is a 7.5 km river crossing on Padma River.
The Gopalganj to Aminbazar line has a total of 226 towers. A total of 11 tall towers have been constructed in the Padma River and also on both sides for facilitating the river crossing.
As the line has been successfully charged at 400 KV voltage, soon after all technical preparations and evaluations, power transmission (load flow) will be started on this line.
With the commissioning of the newly constructed line, the previously constructed Payra-Gopalganj 400 KV line and Gopalganj-Mongla 400 KV line have been connected to the Aminbazar grid substation on the outskirts of Dhaka.
This has made the connection to the national grid stronger and more reliable with the greater Khulna and Barishal regions, the PGCB mentioned.

Govt fails to take power from Payra plant, counts huge losses in capacity payment
The government is counting a monthly loss of Tk 130 crore due to delay in laying a high-priority transmission line that would take electricity from the Payra power plant to Dhaka across the River Padma.
According to official sources, the amount is being paid as “capacity payment” to 1320 MW Payra power plant, a Bangladesh-China joint venture project, which is now ready to supply electricity to the national grid for distribution in Dhaka adjoining areas.
In this case the capacity payment means the government’s commitment to purchase power generated at the plant at an agreed-upon rate. The government still has to pay the plant for its generation (capacity) even if it is unable to buy the electricity from it.
The government is not ready to purchase electricity from the plant as it has failed to complete work on the 164.6 km 400 kV double-circuit transmission line that would supply power from Mongla to Dhaka’s Aminbazar via Maowa connected by the national grid.
The project has hit some hurdles in crossing the mighty river, where a multipurpose bridge is being built to connect Dhaka with the country’s south-western region.
The official document of Power Grid Company of Bangladesh (PGCB), the implementing agency, shows the project was scheduled to be implemented by December 2020. After repeated extensions, the schedule has now been set for December 2021.

Officials, however, apprehend the project might not be completed even by the latest deadline due to a major constraint in the work on crossing Padma River.
Nasrul Hamid, state minister for power, energy and mineral resources, acknowledged the loss government is incurring and the hurdles the project is facing.
“We are trying to resolve the issue,” he told UNB adding “We have nothing else to do but to wait.”
Power Division officials blamed the excessive delay on Padma Bridge construction authority which was tasked to lay foundations for the construction of towers within the river area.
