The Bangladesh Power Development Board (BPDB) has lined up a total of 51 power plants, having total generation capacity of about 3990 MW, for retirement by 2025.

According to an official document of the BPDB, the state-owned principal organization in the power sector, the retirement schedule includes 15 plants from the public sector and 36 from the private sector.

The document-Annual Report 2021 of BPDB-reveals that of the 51 power plants, some 12 plants with total capacity of 1154 MW will be put on retirement in 2021-22, 14 power plants having total capacity of 890 MW in 2022-23, 22 power plants of total 1,770 MW capacity in 2023-24, and 3 plants, having 167 MW capacity, are going to be retired in 2024-25 fiscal year.

The BPDP data also shows that of the total 51 plants, 33 are gas-fired and the remaining 18 plants are liquid fuel-fired.

About the schedule of the retirement, a senior official of the BPDB said that most of the listed plants of the public sector, installed in 1987-97, are aged 25-35 years.

"These plants have already lost their actual capacity and became very inefficient in terms of production cost", said an official adding that the private sector plants which are going to retire are mostly rental and quick rental.

State Minister for Power, Energy and Mineral Resources Nasrul Hamd in a recent webinar said that the government will gradually send the costly rental, quick rental and inefficient liquid-fuel fired plants to retirement.

Currently, the country's installed generation capacity is about 25,514 MW while the available generation is about 13,000 MW which shows a huge surplus capacity remained unutilized.

Many economists and energy experts are critical of such huge surplus capacity as the government has to pay heavily for the capacity of private sector plants even if the power is not purchased.

BPDB chairman Delwar Hossain recently also admitted that they have to count a loss of Tk 16,000 crore for buying electricity at a higher rate and selling it to the public at a lower rate.

To cover up the loss, the BPDP recently submitted a proposal to the Bangladesh Energy Regulatory Commission (BERC). But the energy regulator is yet to respond to the BPDB appeal, said a member of the BERC.
