PQ Description:
Design, Procurement, Installation and Commissioning of 50 km, 161kV HVAC Over Head Transmission Line with OPGW from Volta — Achimota - Mallam and from 161 kV Kumasi Substation (K1BSP) — 161 kV Anwomaso Substation (K2BSP).

The Ghana Grid Company Limited (GRIDCo) has received a loan from the Agence Française de Développement (AFD) towards the cost of the construction of the 330kV Kumasi-Bolgatanga Transmission Line Project as part of the WAPP Inter-zonal Hub Transmission Project, and intends to apply part of the proceeds of the Credit Facility for eligible payments under the contracts for the Re-construction and Commissioning of the Transmission Lines from Volta (Tema)-Achimota-Mallam in the Greater Accra Region and 161 kV Kumasi Substation (K1BSP) to 161 kV Anwomaso Substation (K2BSP) in the Ashanti Region of Ghana as well as associated Substations termination Works.

The Ghana Grid Company Limited (GRIDCo) therefore intends to prequalify contractors/or firms for the transmission line works for the execution of the Project.

The Project will be tendered as three (3) transmission line lots and contracts awarded separately or in multiples based on the most economic consideration as indicated below:

• VTR1-1: Construction of 26 km 161 kV transmission line from Achimota to Volta
• VTR1-2: Construction of 12 km 161 kV Achimota to Mallam Transmission Line
• VTR1-3: Construction of 12 km 161 kV K1BSP — K2BSP Transmission Line

The works required under the Project will involve decommissioning of the existing transmission line:

• Reconstruction of 26 km of two (2no.) single circuit 161 kV lines between Volta-Achimota Substation with 161 kV TERN double circuit line
• Reconstruction of 12km single conductor double circuit 161kV line between the Achimota-Mallam Substations with
• Reconstruction of the existing 12km of single circuit 161kV line between the 161 kV Kumasi Substation (K1BSP) and 161 kV Anwomaso Substation (K2BSP) with a 161kV double circuit line using twin bundle TERN conductors.

The Works shall include all relevant designs, procurement, installation and commissioning of 161 kV HVAC Overhead Transmission Line as well as all associated surveys, engineering, civil works and relevant substation termination works. The new lines would be constructed within the existing ROW. The works involves the replacement of the existing towers with suitably designed lattice towers to carry twin bundle TERN conductors as well as OPGW and Alumoweld Shieldwire.

It should be noted that the 161 kV Transmission Lines project works will be spread over 12 month and construction of all the lots will run concurrently.
