Project Description
The proposed Project involves setting up of a greenfield 341 MW combined cycle gas turbine (CCGT) power plant at Parkul village in Aushkandi union under Nabiganj Upazilla of Habiganj district, about 180 km North West of Dhaka in Bangladesh (the "Project"). The main plant will comprise a combination of gas turbine (1x222 MW), heat recovery steam generators (HRSG) and steam turbine and generator (1x119 MW), in a combined cycle configuration. The gas turbine will have dry low NOx (DLN) combustors. The gas turbine and the steam turbine will be housed within a turbine building. A vertical configuration HRSG with a 70 m high stack is proposed. A by-pass stack of at least 45 m height for simple cycle operation will also be provided Natural gas for the SBPCL II power plant will be supplied by Jalalabad Gas Transmission and Distribution System Limited ("JGTDSL") from the existing Bibiyana gas field. The gas will be supplied through a dedicated 20 inch high-pressure buried pipeline, approximately 8.8 km in length stretching from the Bibiyana gas-field upto the gas Regulating and Metering Station (RMS) in the Project site. The power generated by the Project will be evacuated to the Power Grid Company of Bangladesh ("PGCB") switchyard, which is being constructed adjacent to the power plant. Power will be evacuated to the national power transmission grid by PGCB through a 70 m long transmission line (`T-line`) to be built by PGCB to connect to an existing transmission line of the national grid. Other significant components of the Project include raw water intake and effluent outfall, cooling towers, generator switch gear, emergency diesel generating set, water treatment plant (including demineralization processes), effluent treatment plant (neutralization), sewage treatment plant, fire prevention, detection, control and fighting systems, water storage tanks including for firefighting system, 4000 liter tanks for liquid fuel storage, stores and hazardous materials storage facilities. The Project EPC contract has been awarded to First Northeast Electric Power Engineering Corporation (NEPC) and China Energy Engineering Group Co. Ltd (CEEC). A closed cooling system with cooling towers is envisaged. Boiler and cooling tower blowdown will be cooled in a basin to within 3 degree C of ambient water temperature before discharging into the Kushiyara River. Water for the plant will be pumped from the Kushiyara river, which is located less than one km from the site. The water pumping station will be 340 m away from the river bank and no barrage is proposed. The main power plant is situated on a plot measuring 11 acres. In addition, it includes a temporary construction lay-down area of about 14 acres including a temporary pontoon jetty, which will be returned to Bangladesh Power Development Board (BPDB) upon completion of Project construction. The following associated facilities (not being constructed by the Company) but related to the Project will be shared with two other Projects, Bibiyana South and Bibiyana 3, that are proposed to be built in future and adjoining this Project. A switch yard of 26 acres for the installation of the electricity sub-station being built by PGCB; A 2 km long access road with a land requirement of 4.2 acres to connect the Project site to the Dhaka-Sylhet (N2) highway being built by BPDB; A 8.8 km gas pipeline (installed below ground with a minimum cover of 1.0 m) from the Project site to the Bibiyana Gas Field at the Karimpur distribution point being built by JGTDSL requiring about 46 acres of land (acquisition of 16.75 acres and right of way on 29.73 acres); A 70 m transmission line from the switchyard to the nearest T-Line tower of the national grid being built by PGCB. The Bibiyana gas field is an existing gas field supplying about 50% of Bangladesh`s natural gas. It is not considered an associated facility as the Project will be just one of many consumers the gas field serves. The land for the Project and its associated facilities is mostly private land. Private land for the Project site, construction lay down area and the access road has been acquired by BPDB and has subsequently been leased to SBIPCL II for a period of 22 years commencing from commercial operation date of the Project. Private land for the gas pipeline has been acquired by JGTDSL and for the switchyard and T-line by PGCB
