Overview
Ulaanbaatar-4 Thermal Power Plant is a 570 MW coal-fired facility in Mongolia, operated by Thermal Power Plant-4 SSH Co. It serves as a key electricity source for the capital region.
Ulaanbaatar-4 Thermal Power Plant is a coal-fired power station located in Ulaanbaatar, Mongolia, with a capacity of 570 MW. It is owned and operated by Thermal Power Plant-4 SSH Co and is currently operational. The plant plays a central role in supplying electricity to Mongolia's largest city and surrounding areas. As a coal power plant, Ulaanbaatar-4 operates under Mongolia's national emission standards, which are influenced by the country's reliance on coal for energy. The facility uses conventional coal combustion technology, typical for plants of its era and scale. Mongolia's power sector is dominated by coal, and this plant is among the largest in the country. The plant's environmental impact is significant due to its coal fuel source, which produces CO2, SOx, and NOx emissions. Its location near Ulaanbaatar, a city with high winter air pollution, raises concerns about local air quality. The facility provides essential baseload power to the grid, supporting residential, commercial, and industrial demand in the region.
Environmental context
The plant's coal combustion generates substantial CO2 emissions, contributing to Mongolia's greenhouse gas profile. Proximity to Ulaanbaatar, which experiences severe winter air pollution, means SOx and NOx emissions from the plant can exacerbate local smog and health issues. The facility's age and technology (subcritical or older) may result in lower efficiency and higher emission intensity compared to modern supercritical or CCGT plants. Regulatory oversight under Mongolian environmental laws aims to mitigate these impacts, but enforcement and modernization remain challenges.
Frequently asked questions
Ulaanbaatar-4 Thermal Power Plant is located in Ulaanbaatar, Mongolia, at coordinates 47.8938 N, 106.8036 E.
The plant has a capacity of 570 megawatts (MW), making it one of the largest coal-fired power stations in Mongolia.
The plant is owned and operated by Thermal Power Plant-4 SSH Co, a Mongolian energy company.
Coal power plants in Mongolia are subject to national emission standards for SOx, NOx, and particulate matter, as well as air quality laws. However, enforcement and modernization of older plants remain challenges.
The plant's coal combustion releases pollutants that contribute to Ulaanbaatar's winter air pollution, which is among the highest in the world. Emissions include sulfur dioxide, nitrogen oxides, and fine particulate matter.
