Georgia - Protection and Control Systems in 10 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 and 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 finalized; 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.

Bangladesh - New 230/132 kV and 132/33 kV GIS substations
In its "Government Vision 2021", the Government of Bangladesh plans to supply electricity throughout the country by the year 2021. A study of the whole transmission network of Bangladesh revealed that a considerable number of grid substations and transmission lines, especially in rural areas, will be overloaded. Also, a number of substations will need renovation and modification to replace their aged equipment and unconventional designs.
Against this background, the present study shall develop necessary measures concerning:
- new 230/132 kV and 132/33 kV GIS substations,
- transmission line and substation renovation / upgrading and development.
The study shall prioritize proposed rehabilitation measures to account for different loan packages under discussion.

The scope of these consultancy services included study, design, preparation of tender documents, tendering and supervision of the supply, the installation and the commissioning of 11 kV outgoing feeder panels at some of the above primary substations. The aim was to utilize the available spare FIRM capacity to serve new customers / connections, to reinforce the existing network and also provide panels for connecting the battery energy storage system (BESS).
