Feasibility Study for the Transmission System Improvement, Western Zone
Objective(s)i.To assess technical and economic justification of the planned transmission system expansion in the power sub-sector, Western Zone
ii. To assess power sector in the project areas, network analysis, route identification, survey of substaitn area etc.
iii. To assess expected benefits on the socio-economic situation of the populations in the project areas including Environmental and Social Impact Assessment (ESIA), mitigation measures and resettlement action.
iv. To perform cost estimation, economic and financial analysis.
Scope of Work1. 132 kV Transmission System:Addition of system components in the Western Zone Grid Network:
 Construction of Khulna(S)-Gopalganj; Double Circuit 132 kV Transmission Line (60 km);
 Second circuit stringing on the existing Gopalganj-Madaripur 132 kV Transmission Line (45 km);
 Bay extension at Khulna South – 2 nos
 Bay extension at Gopalganj – 3 nos
 Bay extension at Madaripur – 1 no.

2. Ishurdi - Rajshahi 230 kV Transmission System project with following subcomponents
 Construction of the Ishurdi-Rajshahi 230 kV double circuit transmission line on steel lattice towers with twin conductor, OPGW shield wire; T/L length about 70 km.
 Extension of 2 (Two) 230 kV bays at the existing Ishurdi 230/132 kV S/S.
 Construction of a 230 kV Cable connection of some 400 m between the Terminal Tower of the a/m T/L at Ishurdi S/S and the existing line bay (none-equipped). This is to avoid crossing of existing T/L or other measures which would entail operational constraints.
 Construction of a new 230/132 kV Rajshahi Substation (230 kV portion, including the development of the entire substation area) and the installation of two 230/132 kV 225 MVA transformer at Rajshahi;
 Extension of 2 {Two) 132 kV bays at Rajshshi-2 132/33 kV S/S (To be built in another project).

3. Jhinaidaha 230/132 kV Hub Substation, 2 x 225 MVA, construction of a new substation to be inserted into the 230 kV T/L Khulna South and Ishurdi
 4 x 230 kV line bay, 2 x 230 kV transformer bays,1 x 230 kV Coupling Bay;
 4 x 132 kV line bays, 2 x 132 kV transformer bays, spare space;
 In-Out 230 kV Ishurdi – Khulna (S) T/L; length about 1.5 km

4. 132/33 kV AIS Substation Pansha (Rajbari) with 2 x 25/41 MVA power transformers; 4 x 132 kV bays
 Construction of new 132/33 kV Substation
 Insertion of the S/S into the existing 132 kV double circuit T/L Bheramara - Faridpur
5. 132/33 kV AIS Substation Mithapukur with 2 x 25/41 MVA power transformers; 4 x 132 kV bays
 Construction of new 132/33 kV Substation,
 Insertion of the S/S into the existing 132 kV double circuit T/L Rangpur – Polashbari
6. 132/33 kV AIS Substation Bhangura with 2 x 25/41 MVA power transformers; 2 x 132 kV bays
 Construction of new 132/33 kV Substation,
 Construction of a new double circuit 132 kV T/L -25 km from Baghabari S/S with one circuit strung
7. Bogra 230 / 132 kV Substation
 Addition of a 225 MVA power transformer (single phase banks)
