1. INTRODUCTION

The reliability of the GSE's transmission infrastructure have been vastly improved for recent years as a result of intensive capital investment programs successfully implemented with the support of international financial institutions and donors. Besides, the improved financial position of GSE for the last few years enabled GSE to implement a number of rehabilitation and construction activities with its own resources and funds. As a result of these joint efforts, about 80% of primary equipment and 30% of secondary equipment at GSE substations, as well as a significant part of transmission lines, have already been replaced or rehabilitated. These projects significantly improved the situation in GSE substations and lines, shortened the outages and maintenance, reduced transmission losses and improved the power transmission quality criteria.

However, GSE is still investing in the remaining portions of the assets to achieve further improvement of the transmission grid. GSE is committed to have all the GSE substations fully rehabilitated/upgraded by 2015-2016, with all remaining primary and secondary equipment replaced and/or refurbished and effectively controlled from the National Control Center (NCC).

The Regional Power Transmission Enhancement Project (the RPTEP) financed from the proceeds of the ADB loan is among the top investment priorities of GSE’s Strategic Development Plan 2012-2020 and, once implemented, will further enhance the reliability and stability of GSE’s transmission and interconnection infrastructure and remarkably improve the capability of cross-border energy exchange for export, import and transit.

The RPTEP activities include the following two physical components: 1. Construction of a new 220/110kV Substation Khorga;

The new Khorga substation, together with other ongoing transmission system investment projects, will improve the reliability of the grid and power supply quality. The new substation will strengthen and stabilize the transmission network operation. It will guarantee stable transmission of energy produced at Enguri HPP to the industrial zone of Poti and to Turkey through Batumi Substation. Besides, it will help stabilize transmission power flows providing additional event redundancy and lowering the incidence of outages.

2. Substation Rehabilitation and Improvement: Lot 1: Rehabilitation of the 500kV substation Ksani, including HV primary equipment and complete relay

protection and control systems; Lot 2: Rehabilitation and expansion of Marneuli substation with 500/220/10kV bays, including:

501MVA autotransformer (3x167MVA +1x167MVA spare); connection to existing 220kV part of Marneuli substation via 220kV line (about 400m); Realignment of existing 500kV lines Vardzia and Mukhrani to ensure looping in and looping out

of 500/220/10kV substation.

Lot 3: Supply and installation of one 125MVA autotransformer 220/110/10 kV for the 220 kV substation Menji, replacing one of the two existing 220/110/10 kV autotransformers (63 MVA).

Once implemented, this project component:

will improve the existing 500 kV and220 kV connections in the east part of Georgia,

Will serve as an additional/alternative source of power supply for Tbilisi metropolitan area in case of emergencies.


Page 5 of 21

Expansion of existing 500 kV link (Akhaltsikhe-Gardabani) with Ksani-Marneuli connection will further increase the reliability and stability of 500kV network, thus increasing the reliability of export/import/transit of electric energy.

Locations of the substations to be constructed and rehabilitated/extended under the Project are highlighted in the map below:

Map 1: Location of the substations (Khorga, Ksani, Marneuli and Menji)

Physical completion of the RPTEP is expected by end of 2016. These two components of the RPTEP, the components 1 (Construction of a New 220/110kV Substation Khorga) and 2 (Substation Rehabilitation and Improvement) involve the activities that could have an impact on the environment. Following ‘Environmental Considerations in ADB Operations’ of September 2006, the RPTEP has been classified as Category B requiring an Initial Environmental Assessment (IEE), which will not have significant irreversible or permanent negative environmental impacts during or after construction and requires preparation of Initial Environmental Examination (IEE). The environmental categorization of subprojects was conducted using ADB’s Safeguard Policy Statement (2009).
