PRESENTATION
The project is being implemented in four (4) Countries:
- Côte d’Ivoire(C)
- Liberia (L)
- Sierra Leone (S)
- Guinea (G)
There are two main infrastructures to be built within the framework of the project:
- The Transmission Line
Four main 225 kV high voltage Transmission Lines (TL):
- 1 TL Man (CI) – Yekepa (L) – Nzérékoré (G) — 202 km
- 2 TL Yekepa (L) – Sierra Leone/ Liberia border — 463 km
- 3 TL Sierra Leone/ Liberia border – Yiben (SL) — 419 km
- 4 TL Yiben (SL)- Kamakwie (SL) – Linsan (G) — 220 km
The total length of the high voltage TL is approximately 1 349 km.
The expected power to be transmitted when the two (2) circuits will be fully operational is 290 MW.
- The Substations
Within the framework of the CLSG project, eleven (11) Substations (SS) will be constructed and one existing SS (Man) will be extended. The locations are detailed in the table below:
Location of SS | Country | Type | Coordinate XY (UTM WGS84) |
MAN | COTE D’IVOIRE | Existing / To be extended | ( 663 340 ; 817 470 ) |
YEKEPA | LIBERIA | 225/33 kV – 40 MVA | ( 536 900 ; 817 620 ) |
BUCHANAN | 225/33 kV – 40 MVA | ( 390 327 ; 655 379 ) | |
MONROVIA | 225/66 kV – 70 MVA | ( 317 283 ; 718 271 ) | |
MANO | 225/33 kV – 40 MVA | ( 246 839 ; 774 887 ) |
KENEMA | SIERRA LEONE | 225/33 kV – 40 MVA | ( 260 939 ; 861 948 ) |
BIKONGOR | 225/33 kV – 40 MVA | ( 271 143 ; 950 827 ) | |
BUMBANA | 225/161 kV – 70 MVA | ( 196 257 ; 999 526 ) | |
YIBEN | 225/33 kV – 40 MVA | (196 649 ; 1 039 812 ) | |
KIMAKWIE | 225/33 kV – 40 MVA | ( 803 361 ; 1 052 918 ) | |
LINSAN | GUINEA | 225/33 kV – 2×15 MVA | ( 779 234 ; 1 138 328 ) |
NZEREKORE | 225/33 kV – 40 MVA | ( 525579 ; 856 028 ) |
An OPGW Network and a SCADA system will be implemented to facilitate the operation of the interconnection. This SCADA system will be located in Regional Control Centre (RCC) in Linsan (Guinea) and will use modern data processing systems providing a safe, reliable and optimal operation of the TRANSCO CLSG Transmission.
We present below the project components per country:
COUNTRY | Km of TL (Total = 1 304 km) | Number of SS (Total =12) |
COTE d’ IVOIRE | 112 km | 1 |
LIBERIA | 537 km | 4 |
SIERRA LEONE | 529 km | 5 |
GUINEA | 126 km | 2 |
