The coal is the primary source of energy for Mongolia and most of the energy generation is being produced by conventional thermal system, fires coal. Rapid development of economy and mining sector of our country is increasing the local energy consumption except from economy crises in recent years. Due to energy shortage during the daily peak load period, additional energy imported with high cost from Russian. It indicates that our country is in dependent situation from energy system of Russian. Therefore, the reliable energy source creation and planting the new energy source with ability to maneuver and no negative influence for environment are required to provide the independence of energy sector.
This feasibility study was documented with regarding estimation and research by purpose to install the “Energy storage system” with rated power of 50MW.
A main purpose and objectives about installing the energy storage power station truly met the documents from government such as the government policy program, the policy to follow about energy from government 2015-2030, the program of integrated energy system and sustainable development strategy. According to the documents above, the parliament of Mongolia has confirmed the “National renewable energy curriculum” and “The Law on Renewable Energy Mongolia” in 2005 and 2007, respectively through the protocol numbered 32. Under the curriculums above and law, renewable energy sector is being developed rapidly, specifically Salkhit wind farm of 50MW and Darkhan solar system of 10MW have been installed successfully and there are several projects in implementation step. The renewable energy resources including solar and wind are with main disadvantages of unstable and unreliable characteristic depending on natural factor and weather condition. In developed countries, reducing the external affects in renewable energy source, renewable energy systems are being used assist with support for uninterruptable operation by the way combining with energy storage power station.
