1.0       BACKGROUND

 

The Federal Government of Nigeria has received a credit on behalf of Transmission Company of Nigeria (TCN) from the International Development Association (IDA) under the World Bank towards the cost of Nigeria Electricity Transmission Project (NETAP).  The Company, therefore, intends to apply part of the proceeds of this credit for payments under the Contract for Engineering Supervision and Site Management of Reconductoring of Transmission Lines Projects (NTP-TR5G and NTP-TR5E).

 

The Nigeria Electricity Transmission Project (NETAP) seeks to redress certain deficiencies and operational constraints of the Nigeria Power Transmission System to allow the efficient dispatch and transmission of Power in the National Grid through additional transmission capacity.  In particular, it will complement efforts under-way for both emergency and long-term measures now being taken to increase generation.

 

Part of the NETAP investment component includes the contracts for the Engineering Supervision and Site Management of the reconductoring of Transmission Lines.  An Engineering consultancy service is therefore required to manage and supervise the works covered under the contracts as mentioned above.

 

The Project management and supervision Consultant to be engaged by TCN will assist its project implementation Unit (PIU) among others in the overall supervision of the 132kV Transmission Line reconductoring Projects Management and Supervision. The Consultant will as well assist the Project Management Unit of TCN in the procurement and inspection of all necessary line material needed for the full implementation of the Project, Construction coordination, quality assurance, safety compliance and testing/ commissioning of the line project.

 

1.1       Status of the Project

 

The TCN carried out studies on its existing transmission network, and some lines were identified as being old and weak and needed uprating and upgrading for a stable and reliable power supply. The lines under consideration are:
