Guinea - Development Scheme for the Electrical Networks of Conakry

With the perspective to develop the country's electricity sector, the Guinean government decided to give a new momentum to the country's electrification programme to augment its citizens’ lifestyle, productivity and earnings. For this purpose, the government sought the financial support of the African Development Bank to implement the rural electrification project.

The study on the development scheme for the electrical networks of Conakry consists of the preparation of a programme to improve electricity allocation from the transmission towards the distribution network by means of the following:

• Construction or renovation of substations
• Restructuring and rehabilitation of the medium-voltage network
• Replacement of medium-/low-voltage substations
• Rehabilitation and extension of the low-voltage network

Burkina Faso - Reinforcement of Electrical Infrastructure and on Rural Electrification (PRIELER)

The objective of this project was the elaboration of draft studies that deliver sufficient justification to implement the following works:

• Restructuring and extension of the electrical networks of Ouagadougou
• Construction of the 132 kV interconnection line Zano - Koupèla

Design studies, preliminary cost estimates, time schedules, detailed design, and tender dossiers were prepared to determine all requirements for an efficient implementation of the two projects.

A feasibility study was carried out for the interconnection line Zano - Koupèla resulting in the detailed design for the line, including line route study, environmental and social impact assessment (ESIA), and the choice of the substation locations.

Georgia - Protection and Control Systems in ten Substations and Rehabilitation of the 35, 10 and 6 kV Switchgears in 13 Substations

GSE provides transmission and exclusive dispatch services to about 50 eligible companies in Georgia. Voltage levels include 500/400/330/220/110 and 35 kV. GSE and its subsidiary own the largest part of the high-voltage transmission network including the National Control Centre. GSE is constantly improving the system's availability and reliability through numerous investment measures. The current project considered two ongoing projects, i.e:

• Rehabilitation of protection and control systems of 10 substations of GSE, and
• Rehabilitation of the 35, 10 and 6 kV switchgears in 13 substations.

Both projects were in progress, with some parts being finalised; for others, commissioning, testing and taking over was ongoing.

USAID and GSE agreed to engage a new oversight consultant (OC) from December 2014 until the end of the projects.
