4 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 , 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 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 4 of 21

5 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 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). 1.1 Construction activities and project progress during the reporting period Civil works under Component 1 - Construction of a New 220/110kV Substation Khorga Following the International Competitive Bidding (ICB) for this component, the contract was awarded to Siemens AG Osterreich (Austria) and the Contract Agreement was signed on 9 th of July, The implementation period from the effective date of the Contract Agreement is 18 months.

Impacts on cultural heritage sites Biological recontamination during earthworks Noise and Dust Caused by Construction Activities and Emissions of Harmful No storage where there is potential for flooding. No storage at less than25m from river/streams, subject to site specific Topography. Topsoil from the sites, which should not be reinstated to the initial conditions should be distributed carefully on the surrounding area. If physical cultural resources are encountered during the construction phase, all works at the find site should be immediately halted. The find should be assessed by a competent expert, and procedures to avoid, minimize or mitigate impacts to the physical cultural resources should be developed by the expert in Cooperation with the relevant local heritage authority. Permanent monitoring during land clearance and excavation activities. Stoppage and suspension of construction activities in case of burial site findings. Notification to the local Division of Veterinary Department. Veterinary clearance before start up. Require adherence to engine maintenance schedules and standards to reduce air pollution; Use of defined, well planned haulage routes and reductions in vehicle speed where required; Periodically water down temporary roads on site; No impacts during reporting period No impacts during reporting period In compliance with IEE requirements, do not need improvement Page 20 of 21

Fuel, oil and hazardous materials should be stored in designated areas with temporary impermeable bunds at distance of at least 100 m from any water course. Refueling of machinery, equipment and vehicles should be undertaken at distance of at least 100 m from any water course. Any major work including oil changing and engine maintenance with the potential for oil to be spilled will be done in designated areas at distance of at least 100 m from any water course and with containment to prevent any oil spills washing away. Waste oil shall be collected and taken away for recycling. Oil contaminated material shall be disposed of at designated waste disposal facilities. Contractors should ensure the proper handling of lubricants, fuel and solvents. All tanks should be placed in a bund of at least 110% of the tank s maximum capacity. Accumulated rainwater in bunds should be pumped out of the bund to either drains or onto the ground if uncontaminated. In case of fuel spillage the spilled fuel should be recollected and the contaminated bund shall be treated using the absorbents: Sawdust, sand or straw. All fuel/hydrocarbon dispensing nozzles are to be of a drip control design and securely locked when not in use. Vehicles should not be left without the supervision during refueling process. All refueling operations on the working sites should use absorbent pads and/or straw To minimize spills, which shall be put in place prior to the commencement of refueling operations. Improved partially Improved, the Contractor has disposed all containers with hazardous materials in to drip trays The Contractor was instructed to construct proper refueling area before Page 21 of 21
