Liquid fuel-power plants to retire in 5 years
The government has planned to put on retirement a good number of liquid fuel-fired power plants, mostly the rental and quick rental ones installed in private sector with the total capacity of 4,390 MW, over the next five years (2019-2023).
According to official sources at the Power Division, the move to bring down liquid fuel use in power generation was taken as part of the government strategy to reduce dependence on liquid fuel and increase the use of gas and coal in power generation.
At present, the generation capacity of liquid fuel-fired power plants is 6,100 MW or 32.59 percent while the total power generation capacity is about 18,000 MW.
As per the year-wise retirement plan, plants having 522 MW production capacity will be out of production in 2019 while 320 MW in 2020, 760 MW in 2021, 1180 MW in 2022, and 1606 MW in 2023.
About the plan, State Minister for Power, Energy and Mineral Resources Nasrul Hamid said the government’s main focus is now on increasing the use of gas in power generation by reducing the use of liquid fuel.
- generation cost in liquid fuel-based plants is much higher than other options. Even in some cases, its costs over Tk 30 per unit in generation,” he told UNB.
Officials at the state-run Bangladesh Power Development Board (BPDB) said they use diesel or furnace oil in generating the 6100 MW electricity of liquid fuel-fired plants.
“But both diesel and furnace oil are costlier than any other kind of electricity like gas-fired, imported LNG-based and hydro,” said a top BPDB official adding that the use of liquid fuel increased significantly in the last 10 years.
According to BPDB annual report 2017-18, the per unit power generation cost in local gas is between Tk 2.47 and Tk2.62 while the generation cost in diesel is Tk 16.62 and Tk 27.46, while Tk 13.26 with furnace oil and Tk 7.22 per unit with coal.
Officials said the power generation through imported gas or LNG started in October 2018, and it will cost Tk 12 per unit.
As per the statistics of Bangladesh Economic Review of Finance Ministry, the use of liquid fuel in power generation was 8.2 percent in 2009 which now has been raised to 31 percent in 2018 while 83.4 percent electricity used to be generated by gas-fired plants in 2009 and it came down to 61 percent in 2018.
As per the latest plan, BPDB top officials said, the use of liquid fuel in power generation will be brought down to 3-4 percent by 2030.
They said the government had to move to increase liquid fuel use in power generation in 2009 as part of a contingency plan to find a quick remedy to the nagging power crisis.
At that time, there was also a plan that the use of liquid fuel will be brought down in the next 10 years with the installation of base-load plants of coal and gas-fired ones.
But that plan was not followed and instead the use of liquid fuel continued to increase until 2018 and it reached 32.59 percent in 2019.
Under the contingency plan, the officials said, the liquid fuel-plants were initially contracted for 3-5 years.
“But the contracts of most of the plants were extended twice or thrice for 3-5 years more as the new base-load plants were delaying to come into operation,” said a top BPDB official.
After the recent introduction of imported LNG in power generation, now the Power Division has decided to put the existing liquid fuel-fired plants on gradual retirement and not to extend their contracts further, Nasrul Hamid said.
“We won’t further renew any contract of liquid fuel-fired plants of any area where gas or coal will be available for power generation,” he said.
He said power generation through imported LNG or coal is cheaper than that of the liquid fuel. “The government will give that preference to use imported gas in power plants which now remain idle for gas shortage,” he said.
