Frequently Asked Questions

Technical/Engineering
  1. What is total length of the tunnel?

    37km (including access adits)

  2. Are tunnels always filled with water?

    Not always, but the majority of the time they are filled.  It is best once a tunnel is filled with water to minimize the number of times it is emptied from an engineering stand.  AGL will periodically empty a tunnel for inspection over the course of the project, but as a general practice keep the tunnels full.

  3. What caused tunnel collapse? What are the results of the test analysis?

    AGL undertook detailed investigation to identify the reason for tunnel damage. Rock samples were taken from affected as well as non-affected tunnel areas. Samples are being sent to international labs in Norway and Austria. It is a very complicated and time-consuming process and may take up to 6-8 months to finalize the results, based on which further construction methods will be identified. As of today, we can say that “uncharacteristic geological conditions” caused damage of the tunnel in some sections. AGL is putting all efforts to finish works and put the project into operations as soon as possible.

  4. How will the water flow downstream of the dams change because of the Project?

    In general terms the flow downstream of the dams will be reduced, however each dam structure has an environmental flow release that is maintained at all times.  This ensures there is a constant release of water 24 hours / day, 365 day per year.  During high flow seasons (rainy seasons) there may be times when additional water is released from the dams beyond the environmental flow.

     

  5. What is the height of Didachara and Skhalta dams

    Didachara dam is 52 meters, and Skhalta dam is 18 meters. 

  6. How the water is diverted to tunnel from reservoirs?

    Each reservoir has a “tunnel intake” structure that is gated and the location where the water enters the tunnels.  When the water rises in the reservoir and the intake gate is open, water naturally flows in to the tunnel due to the incline.

  7. How often water will be released from the dams? How locals will be informed about the release?

    Water release beyond the environmental flow at each dam location will occur primarily during two events:  1)Flushing:  The times when the gates at the dam are opened to flush sediment downstream, and 2)High Inflow:  Times when the amount of water entering the reservoir exceeds the capacity of the reservoir and water needed for power generation.  The flushing is planned to take place during these high inflow times, which is anticipated to be approximately two times per year (March/April and October/November).  AGL will share this with the municipalities in advance and as well will sound alarms on the dams when gates are opening.

  8. To what level will the water reach in riverbed after the release?

    In general terms the water levels in the riverbed will rise 1-3 meters above normal levels (environmental flow levels), but should be within pre-dam river levels.  Downstream water levels during release are not expected to rise to structures along the river bank.

  9. Where is the generated electricity sold?

    Both in Georgia and Turkey.

  10. Will there be any electricity tariff price decrease for locals?

    The intention of the Shuakhevi HPP is to provide more reliability to the national grid.  With additional power generation in Georgia the amount and duration of outages (periods with no power) should reduce, thereby having a more reliable supply of power to customers.  Power tariffs are set by the government.

  11. What is the lifespan of the power plant?

    Different components of the power plant have different lifespans; moving parts in the turbines and generators have more wear and will need to be replaced more frequently.  Civil structures including dams, tunnels, and buildings are designed for long-term life spans (50+ years).  All structures will be monitoring on a fixed schedule throughout the project.

Environment
  1. Will operation of HPP cause any environmental impact?

    From 2013 AGL has been conducting monitoring of river habitats, mainly fish, macroinvertebrates and mesohabitat surveys, which will continue regularly during operational phase. Local and international experts are involved in reviewing and interpreting monitoring data. In case monitoring reveals any impact, specific and robust mitigation measures will be implemented by the company, which will ensure to achieve no residual adverse effects to biodiversity. With all mitigation measures successfully implemented, the project is not expected to cause significant irreversible damage to the local ecosystem over the long term.

  2. Will water users downstream of the dam be affected by the dam operation? How will stakeholders be convinced that environmental flow is being released by the company?

    The needs of the water users downstream of the dam have been considered and the environmental flow has been prescribed by the Government of Georgia (GoG). The environmental flow will be released and the flow figures are submitted to the GoG and disclosed on the website here.

  3. What habitat restoration/compensatory activities will be undertaken by the company?

    AGL has already planted 2,700 red listed trees in the Vashlovani and Dachara villages in Khulo municipality to compensate forest affected by project footprint.  The company is working closely with the Adjara forestry Agency to find additional land for compensatory planting. In case additional land for compensatory planting cannot be secured, AGL will provide financial compensation to Adjara forestry Agency to conduct compensatory activities on behalf of AGL. This is still being negotiated with the national and local authorities, land owners, and stakeholders.

  4. How were locations for Spoil Disposal Areas (SDAs) identified and how will they be managed?

    Team of international and local experts selected locations taking into consideration safety and environmental factors. AGL has developed project/plan individually for each of the Spoil Disposal Areas (SDAs), which was approved by the Ministry of Environment.

  5. Is the material in the spoil disposal areas harmful to people or animals?

    No.  The material in the spoil disposal areas is almost entirely composed of rocks that were excavated during the construction of the tunnels.  This material has been placed in spoil disposal areas, and the long term intention is to re-cultivate these areas for grazing purposes in the future.

  6. Are locals allowed to use SDAs for business and commercial purposes, farms etc. on the SDAs?

    The land used for spoil disposal is owned by AGL and is to be used exclusively for the project purpose. Additionally, AGL is obligated to restore the area and monitor rehabilitation for 2 years, after which the company will return the land to state.

  7. Will dam operation affect spring water users?

    AGL has undertaken spring water monitoring at 366 locations between 2013 and 2017 during the construction phase. The monitoring results were submitted to the Ministry of Environment and Natural Resources Protection of Georgia as per the regulatory requirement. As no impact was observed during the monitoring period, GoG has instructed not to continue this monitoring any further in the operational phase.

  8. Will dam operation cause pollution of river water?

    Hydropower is clean, renewable energy. There is no risk of river pollution during dam operation. AGL will undertake water quality monitoring regularly for necessary parameters.

Community
  1. Will AGL continue implementation social projects in the operational phase?

    Yes. AGL has developed Operational Phase CSR Strategy for four years. This document has been approved by the Board of Directors. The document envisions continuation of social programs within AGL’s CSR efforts. The company identified support of long-term economical development of the region as a main focus of its CSR programs during the operation phase.  

  2. Will there be employment for local people during operational phase?

    Currently, more than 80% of the work force comprises of local Georgian employees and we expect to increase this further in the next two years by phasing out expat employees in a planned manner.    

  3. What kind of skills are required for the operational phase?

    During the operations phase most of the workers have a technical mechanical and/or electrical background.  These employees are responsible for operating the plant and doing ongoing maintenance on the plant during operations.  Additionally there will administrative work including accounting, government compliance, and other administrative tasks.

  4. Why did the Company give compensation for houses?

    AGL provided financial assistance to the local government for rehabilitation of houses in the communities in both municipalities within its social responsibility programs at the requests of the local authorities.

  5. Will there be livelihood restoration projects, especially cattle breeding?

    No. AGL has already undertaken its commitments as described under Detailed Livelihood Restoration Plan.  For those AHs who failed to participate, AGL does not intend to undertake additional programs.

  6. What taxes will be paid by the Company?

    The Company pays all taxes which are applicable by the Georgian Tax Code, these are: income tax, revenue tax, VAT, and property tax. The latter is paid directly to the municipal budgets.

  7. Will affected communities have any influence on distribution of taxes paid by the Company?

    1% of property tax which is paid to the local municipality is owned by the municipality. This is the municipality’s priority to distribute the money. Investor cannot interfere with it. You should check it with your municipality.   

Safety
  1. What kind of safety measures will be implemented around the dams and reservoirs?

    Necessary safety signage, safety warnings and instruction will be displayed in Georgian language for the operational areas including dams, storage areas, rivers etc. Besides, sirens shall be sounded:

    1. a) 15 mins before release of water as warning;
    2. b) Second siren shall be sounded on release of water.
    3. c) During emergencies waving sirens shall be sounded.

    Release of water from dam will increase height of water in the river but it will not go beyond its natural riverbed. AGL has recruited 2 security personnel who will be responsible to oversee the reservoir parameter. Life guards will have lifesaving kit which will be made available for 7/24. Intruder and CCTV system are installed for security assistance.

  2. Can we fish in the reservoir?

    No, fishing is strongly prohibited in dam and reservoir areas for safety reasons.

  3. Can we swim in the reservoir?

    No. Swimming in the reservoir is not allowed. Water levels will rise and fall approximately 10 meters and it is dangerous.

  4. Can our cattle fall in the reservoir and drown?

    Some areas of the Didachara reservoir where slopes are very steep will be fenced. Local population should be very careful and watch out that their cattle do not fall in the reservoir.

  5. In case of an emergency whom shall we contact?

    In case of emergency, please dial 112. Emergency Management Agency Adjara has sub units at each municipalities in Adjara region i.e. Keda, Shuakhevi and Khulo etc. on 24/7 basis. This organization, must be informed or contacted in any kind of emergency. It will take between 15 to 60 min to reach the emergency location.
