Project Presentaton

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:

  1. The Transmission Line

Four main 225 kV high voltage Transmission Lines (TL):

  1. 1 TL Man (CI) – Yekepa (L) – Nzérékoré (G) — 202 km
  2. 2 TL Yekepa (L) – Sierra Leone/ Liberia border — 463 km
  3. 3 TL Sierra Leone/ Liberia border – Yiben (SL) — 419 km
  4. 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.

  1. 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
