Nanchuan Heart River power station — China

Coal power plant in Chongqing Shi, China. Approximate location 29.2707, 107.2619.

CoalChongqing ShiChinasubcriticalCO₂ modelled

Nanchuan Heart River power station is a 25 MW coal power plant in Chongqing Shi, China. It is operated by Chongqing Nanchuan Aixi Electric Co Ltd. Based on its capacity (estimated), it can supply roughly 31k homes (estimated). It ranks #4927 of 6,685 China power plants by installed capacity. Commissioned in 1998, it is around 28 years old — long-established. Its modelled annual emissions are 112,743 t CO₂/yr (Climate TRACE), equivalent to about 26k cars driven for a year. In context, coal supplies about 54.3% of China's electricity; the national grid averages 525 gCO₂/kWh (41.7% low-carbon) (2025).

In context: how this plant compares

At 25 MW, Nanchuan Heart River power station is below the median coal plant in China (700 MW). Technically it is described as subcritical. Coal plants burn pulverised coal to raise high-pressure steam for a turbine; they run as baseload but are the most carbon-intensive mainstream source and the first targeted for retirement or efficiency retrofits.

Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

~112,743 t CO₂/yr (modelled) — in everyday terms

This facility's annual emissions are roughly equivalent to:

625railcars of coal burned
23khomes' electricity use for a year
113kacres of US forest absorbing CO₂ for a year

Equivalencies via US EPA Greenhouse Gas Equivalencies; modelled emissions from Climate TRACE.

Local climate & thermal context

This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 29.3°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 15% below the median power plant in this dataset — a proxy for how much extra energy heated equipment must replace through its surfaces in winter.

Climate heat-demand index: 44/100 — this site sits in the mid third of the power plants we cover by heating degree-days.

Site climate & environmental severity

This site sits in a moderately corrosive environment (estimated ISO 9223 class C3 — Medium), with humidity / wetness the leading environmental stress.
