Overview
Datang Liancheng-2 power station is a 600 MW coal-fired power plant in Gansu, China, operated by Datang Gansu Power Generation Co Ltd. It is currently operational.
Datang Liancheng-2 power station is a coal-fired power plant located in Gansu Province, China, with a capacity of 600 MW. The facility is owned and operated by Datang Gansu Power Generation Co Ltd, a subsidiary of China Datang Corporation, one of the country's major state-owned power generation enterprises. The plant contributes to the regional power grid, supporting industrial and residential electricity demand in northwestern China. As a coal-fired power station, Datang Liancheng-2 operates under China's national emission standards for thermal power plants, which include limits on SO2, NOx, and particulate matter. The plant's technology is typical for a medium-to-large coal unit in China, likely employing subcritical or supercritical boiler technology. China has been progressively tightening emission regulations, requiring existing coal plants to install flue-gas desulfurization (FGD), selective catalytic reduction (SCR), and electrostatic precipitators (ESP) to meet standards. The plant's location in Gansu, a region with significant coal reserves and a growing renewable energy sector, places it within a diverse energy mix. While coal remains a key energy source, the facility faces environmental scrutiny due to its carbon emissions and local air quality impacts. The plant's operational status and capacity make it a notable contributor to the regional power supply, though it operates in a regulatory environment increasingly focused on reducing coal dependence and promoting cleaner energy sources.
Environmental context
The plant's coal combustion releases CO2, SO2, NOx, and particulate matter, contributing to local and regional air pollution. Gansu's arid climate and proximity to populated areas may exacerbate health impacts from emissions. The facility's age and technology (likely subcritical or supercritical) influence its efficiency and emission intensity. China's regulatory framework, including the Air Pollution Prevention and Control Action Plan, mandates strict emission limits and promotes retrofitting of existing coal plants with advanced pollution control technologies.
Frequently asked questions
Datang Liancheng-2 power station is located in Gansu Province, China, near the city of Lanzhou. Its coordinates are approximately 36.52° N, 102.87° E.
The plant has a capacity of 600 megawatts (MW), making it a medium-to-large coal-fired power station in China.
The plant is owned by Datang Gansu Power Generation Co Ltd, a subsidiary of China Datang Corporation, a major state-owned power generation company.
Coal power plants in China must comply with national emission standards for SO2, NOx, and particulate matter, as well as carbon intensity targets. Regulations include the Air Pollution Prevention and Control Action Plan and the 14th Five-Year Plan, which mandate retrofits with FGD, SCR, and ESP systems.
Chinese coal power plants commonly use subcritical, supercritical, or ultra-supercritical boiler technology. Newer plants tend to be supercritical or ultra-supercritical for higher efficiency and lower emissions, while older units may be subcritical.
