Bangladesh - Feasibility Study of the Transmission System Improvement, Western Zone
Bangladesh faces chronic power shortage with an estimated demand gap in the magnitude of 1900 MW and power outages in urban areas between 5-10 hours a day. Taking into account the demand forecast(s), the current load shedding and the extreme power shortage and operational constraints, PGCB launched the "Power Transmission Improvement Programme" and approached the Government for external sector assistance.
The project covers the following technical measures:- Construction of 132 kV double-circuit transmission lines and line in-/line outs to substations
- Stringing of a second circuit on an existing 132 kV line and installation of OPGW
- Construction of 230 kV double-circuit transmission lines and line-in/line-out to existing lines
- New construction of three 132/33 kV and one 230/132 kV substation
- Extension of a total of five 132/33 kV and one 230/132 kV substation (1 GIS substation)

Rwanda, Burundi - Regional Interconnection Project (220 kV Transmission Line Kigoma - Butare - Ngozi - Gitega and 220/110 kV Substations)
The project was part of the NELSAP Regional Transmission Program that aimed at interconnecting five of the Nile Equatorial Lakes Countries, i.e. Burundi, DR Congo, Kenya, Rwanda and Uganda.
The project interconnected the electricity networks of Burundi and Rwanda through the construction of a new 220 kV single-circuit transmission line with a total length of 143 km. The line will initially be operated on the 110 kV level and might later be upgraded to 220 kV.
The project also included the construction of two new 220/110 kV substations, the extension of two existing 110 kV substations and the construction of 11.2 km of 30 kV line for rural electrification of Gisagara (Rwanda).
