Overview
Yongchuan Songgai power station is a 270 MW coal-fired plant in Chongqing, China, operated by China Power Investment Corporation. It supplies electricity to the regional grid.
Yongchuan Songgai power station is a coal-fired power plant located in Yongchuan District, Chongqing, China. With a capacity of 270 MW, it falls into the small-to-medium scale category for coal plants in China. The facility is owned by China Power Investment Corporation (CPI) and is currently operational, contributing to the region's power supply. The plant operates on coal, a fuel source that is abundant in China but associated with significant CO2, SOx, and NOx emissions. As a coal-fired facility, it is subject to China's national emission standards and environmental regulations, including the Air Pollution Prevention and Control Action Plan. The technology employed is likely subcritical, typical for plants of this vintage and size in the region. Environmentally, the plant's location in Chongqing, a densely populated urban area, raises considerations regarding local air quality and public health. Its role in the grid is to provide baseload power, supporting industrial and residential demand. The facility's age and technology profile may influence its efficiency and environmental footprint compared to newer supercritical or CCGT plants.
Environmental context
The plant's coal combustion releases CO2, SOx, NOx, and particulate matter, contributing to local air pollution and greenhouse gas emissions. Its location in a populated area increases potential health impacts. The facility's age and subcritical technology likely result in lower efficiency and higher emissions per MWh compared to modern plants. Regulatory compliance with China's emission standards is essential for its continued operation.
Frequently asked questions
Yongchuan Songgai power station is located in Yongchuan District, Chongqing, China.
The plant has a capacity of 270 megawatts (MW), making it a small-to-medium scale coal-fired power station.
The plant is owned by China Power Investment Corporation (CPI), a major state-owned power generation company in China.
Coal power plants in China must comply with national emission standards under the Air Pollution Prevention and Control Action Plan, including limits on SO2, NOx, and particulate matter. Plants are also subject to carbon intensity targets under China's climate goals.
With a capacity of 270 MW and likely subcritical technology, the plant is smaller and less efficient than modern supercritical or ultra-supercritical coal plants, which typically exceed 600 MW and achieve higher efficiency with lower emissions.
