- The EGHPP generated energy will be connected to the CES via 2 circuits double conductors with capacity of 220 kV.
- The main criteria for meeting the environmental objective are avoided of carbon dioxide (CO2) emissions, and the specific carbon offset of the project is determined in terms of carbon dioxide (CO2) emissions avoided per GWh over the lifetime of the project and thus EGHPP reduces 709 thousand ton of CO2 annually.
- By 2022，EGHPP is to produce 581 million kWh annually at minimum and the annual electricity generation is to vary between 581 to 2662 million kWh.
- By the April 2014 investigative study discovered 218 artifacts at the hydropower plant DAM SITE (910м), and 24 artifacts at the infrastructure route.
- 242 artifacts are planned to be excavated and preserved in 2014-2015.
- 423 species of plants grow at the Egiin Goliin DAM SITE.
- Hydropower costs less than most energy sources.
- Renewable Energy creates three-times more jobs than fossil fuels.
- In 1878 the world's first hydroelectric power scheme was developed at Cragside in Northumberland, England by William George Armstrong.
- Hydropower today provides about 20 % of the world's electricity and is the main energy source for more than 30 countries.
- Hydropower facilities can quickly go from zero power to maximum output, making them ideal for meeting sudden changes in demand for electricity.
- Hydropower can also be used for water supply, flood control, irrigation and even recreation purposes.
- The financial status of the hydroelectric industry is generally healthy due to long equipment life and low maintenance and operating costs.
- Egiin Goliin hydropower plant is estimated to cover the investment in 20-25 years of time with its sales income.
- Thermal power plants in UB city burns 3.5 million tons of raw coal, pollutes the air with 4 tons of coal, 4.5 million cubic meters of gas and 6kg emissions of sulfur gas.
- The Eg river is Mongolia's third largest river, and at the proposed dam site has a catchment area of about 40,000 km².
- Due to Mongolian country characteristics and situation, the value of 315 MW installed capacity has been selected.
- There are 21 types of fish at the Eg river.
- The new bridge that will be built across River Selenge will be a steel concrete bridge.
- Turbines and generators are expected to be replaced after 32 years of operation.
- Peak demand of the Mongolian energy system reached 948 MW, exceeding both installed and feasible generation capacity and the reason for increased imports of electricity
- Electricity is imported from Russia to the Central Region Integrated System via Selendum sub-station Russia and Darkhan sub-station Mongolia.

DETAILED ENVIRONMENTAL IMPACT ASSESSMENT -
The main basis of any project and big construction is general policy for Environmental protection study and monitoring that should be performed constantly in all stage of implementation. Following this feature all studies have been done in accordance with the Environmental law and legislations. So in relation with the project the Environmental baseline study and Detailed environmental impact assessment and other specific studies of specialized organizations are performed. Due to big scope of work of the project and requirement to start construction of infrastructure in advance and to study potential impacts in detail. The Detailed environmental impact assessment has been done separately as for Hydro Power Plant and for infrastructure. That is an advantage of the study.

1. The professional company for environmental study and assessment ENCO LLC performed the amendment of the detailed Environmental impact assessment based on amendment of environmental baseline study for Egiin Goliin HPP along the dam that would be constructed within the Egiin Goliin HPP project and upstream 60 km long reservoir and characteristics of updated Feasibility study of the project. Also environmental baseline study of the project is developed and conclusion of the general assessment issued by related governmental organizations. The amendment of the detailed environmental impact assessment of the project was adopted by Professional council of assessment of the Ministry of Environment and Green Development in October of 2014.
-
CONCLUSION -
It is possible to implement the Egiin Goliin HPP project with low negative impact to environment if the actions and recommendations defined by the detailed Environmental impact assessment to mitigate negative impact which might be happened during construction period and operation of HPP will be implemented in coordination with environmental protection plan and environmental monitoring program.
