Dohazari 100 MW Furnace Oil Power Plant, also known as Dohazari-Kaliaish Peaking Power Plant or Sangu Peaking Power Plant, is a reciprocating engine-based power plant situated in Dohazari under Chandanaish Upazila in Chattogram District of Bangladesh (Location: 22.1523, 92.0712). It is sponsored by Bangladesh Power Development Board (BPDB) as a State-owned Power Plant (SOPP) for 22 years. The power plant started its commercial operation on 31 December 2011 and, as per schedule, it will retire on 30 December 2036.


Capacity

The installed and net capacity of the Dohazari peaking power plant is 102 MW and 100 MW respectively. 


Context

In 2011 , Dohazari 100 MW (BPDB) HFO Power Plant started its commercial operation located about 43 km from Chittagong. All the work in this region depends on this  power plant. From agricultural work to factories, everything depends on this power plant. Apart from meeting the needs of the rural people, it is also taking other steps to avoid power shortages. From this power  plant, electricity supply to South Chittagong is kept normal through the national grid. 450 tons of fuel oil is required to run the plant full time one day. These fuels are transported daily through railracks (in oil tankers) because of the construction of Kalurghat Bridge (DA, 2023). It doesn't supply the electricity according to the aggrement. After starting the commercial operations  89 MW is available from the 100 MW Dohajari power plant (DP ,2023),

The Dohazari plant was constructed by Chinese company Guangdong Power Engineering Company, with machinery supplied by Wärtsilä Engine of Finland. The plant is equipped with dual-fuel facilities, capable of running on both gas and furnace oil. (TDS, 2010) The plant consists of not more than 16 identical units of heavy-duty, medium-speed engine generators (500–750 rpm), diesel cycle engines fired on HFO, with provision to convert to natural gas in future, delivering a net output of 98.164 MW at site conditions of 35°C, 1.013 bar, and 98% relative humidity.

Environment

HFO contains high levels of sulfur and other pollutants, which are released into the atmosphere when burned. This can contribute to air pollution, leading to respiratory problems and other health issues in nearby communities. Environmental Impact Assessment (EIA) report is mandatory for this power plant and in accordance with Section 12 of the 1995 Bangladesh Environment Protection Act, it is obligatory for industries, including those causing pollution like power plants, to undergo both an Initial Environmental Examination (IEE) and an Environmental Impact Assessment (EIA) as outlined in the 1997 (superseded by ECR 2023) Environmental Conservation Rules (MOLJPA 1995; MOEFCC 1997).
