Krasnodar GRES Project Volume I11 Environmental Assessment

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
