Energy Situation
The power system of Mongolia accounts for 3% of GDP and supplies 80% of the population with electricity. The system is considered to be a major branch of the economy and infrastructure sector of Mongolia and it strongly influences the social and economical viability of the country. Approximately 80% of the consumed electricity is generated in coal-fired power plants, 4% is produced by diesel generators and 3% by renewable energy sources (mainly hydropower). The remaining 13% is imported, mainly from the Russian Federation.
In 1989 the total electricity consumption amounted to 2,900 million kWh. In the period between 1990 and 1998 electricity consumption dropped tremendously owing to the transition to a market based economy whereby a major portion of the industrial companies was closed. Due to the lack of financial resources, the energy sector faces huge problems to maintain and repair the existing equipment which is in obsolete condition. The Mongolian government has taken actions for the rehabilitation of equipment and auxiliaries by using foreign loan and assistance. From 1998 to 2007 the average annual consumption increased by 3.7% and reached a level of 3,000 million kWh in 2007. On average, the industrial and construction sector accounts for 62% of the energy consumption. The housing and communal service sector consumes 24% and the transportation and communication sector 4%. The rest, 10%, is consumed by the remaining sectors of the Mongolian economy. The totally required capacity in Mongolia is 740 MW at present and will increase to 780 MW in 2010.
Energy systems
The power system of Mongolia consists of the three unconnected energy systems (Central, Western and Eastern Energy System), diesel generators and heat-only boilers in off-grid areas.
The Western system provides three province (Aimag) centres and its 22 district (Soum) centres with electricity imported from Russia. The peak load of the imported electricity reaches 8.0 MW. Currently, there is no own generation capacity. It is planned to build two smaller coal plants with a capacity of 24 and 40 MW respectively to reduce dependency on Russia
The Eastern Energy System is based on the 36 MW Choibalsan Power Plant. The plant supplies the Aimag and Soum centres of the Dornod and Sukhabaatar provinces with electrical power.
The Central Energy System consists of five heat and power cogeneration power plants of Russian design, for base load operation, interconnected by a 220 kV line with the Russian-Siberian grid, one transmission network and four distribution networks. The system supplies power to the cities of Ulaanbaatar, Darkhan, and Erdenet and to the centres of 13 Aimags and about 150 Soum centres. The total capacity of the central grid is 680 MW or 840 MW including the maximum potential supplies from Russia. The total load currently amounts to 740 MW and is expected to increase to 780 MW by next year.
Concerning the Western and Central systems, the Mongolian operators are not able to balance the demand and supply in the grid adequately. The missing balance load has to be compensated by additional supplies from Russia which comes at a high price.
Although there has been some improvement in recent years, the country's coal-power-heat supply system remains in poor condition, and is unable to meet the basic supply requirements of industrial and commercial enterprises and the urban population. Power system losses remain very high. In addition to exceptionally high losses and internal use in the CHP plants, losses and faultily metered or unmetered consumption in the electricity distribution system are in excess of 25%. Poor bill collection and revenue management practices cause further financial losses. Although the financial situation has improved substantially since mid-1996, it remains precarious, due to the high system losses, revenue collection difficulties and insufficient tariff levels (especially for heat) to cover the service cost. Financial information systems are insufficient and/or inappropriate, and skills and procedures need to be developed to undertake proper financial planning. Hardware, software and skills in Mongolia are inadequate for efficient operation of the main generation and transmission system, and interfaces with distribution systems.
Future Developments
The MoE (Ministry of Energy) is in the planning process of constructing two coal-fired power plants (24 MW and 40 MW), supplying the Western system. Chinese investors plan to construct a gigantic 4,800 MW coal power station in southern Mongolia during the next decade. It will be supplied with coal from Mongolia but the electricity generated is exclusively transmitted to China. It can be seen as a Chinese power station in Mongolian territory which will also not be connected to the central grid.
