* 50.4% 3.0 DESCRIPTION OF THE PROPOSED PROJECT Within this chapter the general overall design criteria for the plant and its components, the project site, fuel characteristics, and natural gas, water, and transmission line connections are described. It will be noted in this chapter that the design of the Krasnodar GRES meets or exceeds all engineering and environmental Russian Federation, World Bank, and international requirements, guidelines and recommendations for combined cycle natural gas plants. Further information on plant design can be found in the Feasibility Study conducted and produced by RoTEP. 3.1 General Project Description In order to address the electric power deficit in the North Caucasus region, a natural gas fired combined cycle power plant is proposed to be built near the village of Mostovskoy in the Krasnodar Krai of Russia. The Krasnodar GRES plant is a 900 MW combined cycle plant with future planned expansion to 1,350 MW. It is composed of two modular blocks of 450 MW each, with each block containing two combustion turbines of 150 MW capacity, two heat recovery steam generators (HRSGs), and one 150 MW steam generator. Using modern combustion technology, power plant efficiency is estimated at with a plant availability factor of approximately 90%. The plant will use a dry cooling tower system to eliminate the need to withdraw large quantities of water from the Laba River and will be fueled with natural gas. The gas will be supplied from a new 60 kilometer pipeline connected to the Trans-Caucasus gas pipeline. Power transmission will be accomplished by connecting to the existing 500 kV and 220 kV transmission systems. 3.2 Site Characteristics and Design Parameters The project site as shown on the site vicinity drawing, Figure 3-1 is located approximately 5 km south of the settlement of Mostovskoy and approximately 2 kilometers from the Laba River. The site, approximately 130 hectares of level farmland, is in a valley with hills on both sides, and slopes towards the north with elevations varying from 410 to 41 6 meters. There is an existing drainage ditch on site which carries storm water from the adjacent hilly areas on the south. There are no known sensitive ecological areas, such as critical habitats, bird nesting areas, or biosphere reserves, either on or sufficiently proximate to be impacted by plant, transmission line, or water pipeline construction or operation. The land for the project has been secured by Kubanenergo from the local government. The top 0.8 to 1.5 meters of soils consists of excellent top soil that will require removal @ from the construction areas and reuse or disposal. The next 6 to 15 meters USAID/KRASEIA/OFFICIAL/EIACH3.DOC 3/26/96 PAGE 3-1
consists of large gravel mixed with clay and sand. Below the gravel there is a solid layer of water tight clay up to 150 meters deep. The water table is approximately 2 meters from the existing ground surface. There is an existing 110 kV transmission line running through the site. Site investigations to assess both the design considerations and the plant design bases necessary for construction and operation, have previously been carried out during the Feasibility Studies conducted by ROTEP. These studies include the hydrology, geology, and meteorological aspects of the subject site. Other investigations carried out as part of the Feasibility Study included: site access, mode of transportation, fuel supply, intake and discharge arrangements for the cooling water, and general findings of the air quality and existing sources of emissions, water quality, acoustic noise pressure levels, animal and plant kingdoms, aquatic flora and fauna, and the sociological environment. The results of these investigations as they apply to plant design considerations and establishing the plant design bases are described below. 3.2.1 Geology The plant elevation will be located above the flood plain as described in feasibility studies conducted by ROTEP. The geological structure of the project site is composed of alluvial pebbly grounds of the Quaternary period, which are underlain by maikop clays at a depth of 10.0-14.0 meters. As a whole, the geolithological structure of the construction site is relatively uniform. The site will be filled to raise the grade above flood level and existing drainage ditch will be relocated to prevent flooding of the site. Based on the geotechnical investigation conducted by ROTEP, site soils will provide adequate support for shallow foundations. These shallow foundations can consist of either spread footings or structural mat. The allowable soil bearing capacity is estimated to be between 0.4 and 0.5 MPa. 3.2.2 Hydrology The hydrogeological conditions of the project construction site are characterized by a universally developed horizon of underground waters, confined to the Quaternary alluvial pebbly deposits. The depth of the acquiferous horizon is from 7.0 to 13.0 meters. However, underground water has been observed to rise up to a depth of 1.0 to 2.0 meters below the ground level. PAGE 3-2
