Project General Description

The Nigeria Transmission Expansion Project – phase 1 (NTEP 1) is part of the national Transmission Rehabilitation and Expansion Programme (TREP). This programme aims to support the rehabilitation and upgrade of Nigeria’s electricity transmission substations and lines, to increase power transmission network and allow distribution companies to improve supply to consumers. NTEP 1 is composed of brownfield and greenfield projects, and aims at strengthening and improving the grid wheeling capacity where the transmission lines are the most constrained. It involves (i) the reconstruction of two (2) 330kV double circuit quad transmission lines, 138km Alaoji–Onitsha and 125km Delta–Benin; (ii) the construction of one (1) 330kV double circuit quad transmission line, 204km Kaduna–Kano; (iii) the construction of two (2) 330/132kV, 2 x 150MVA Sub stations at Zaria and Millennium City; (iv) The construction of two (2) 132/33kV, 2x 60MVA Sub stations at Rigasa and Jaji respectively. The three (03) components included in NTEP 1 are: (1) strengthening and improvement of the electricity transmission system, (2) impact mitigation and compensation, and (3) capacity building and technical assistance.

Project Objectives

The purpose of the project is to increase the wheeling capacity of the grid to avail of the stranded generation capacity and improve reliability of the gird and power to consumers.


The Bank will provide a loan of USD 210 million, along with an AGTF loan of USD 50 million to the Federal Government of Nigeria (FGN), which will be on-lent to TCN who is the direct beneficiary. The project will increase TCN’s capacity to wheel power from generation to the distribution companies. The project will have a direct impact on Nigeria’s economy, its businesses and population by significantly improving the quality of supply of electricity, therefore reducing the use of alternative solutions, such as small-scale diesel generators, to meet energy needs.
