Huaneng Haimen power station is a 4,144 MW coal power station in Guangdong, China. It is operated by China Huaneng Group Corporation (CHNG). Based on its capacity (estimated), it can supply roughly 5,185,920 homes (estimated). It ranks #28 of 5,959 China power plants by installed capacity. Commissioned in 2011, it is around 15 years old — relatively modern. Its measured emissions of 13,989,000 t CO₂/yr (Climate TRACE) are equivalent to about 3,260,839 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).

This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a humid subtropical (dry winter) climate (Köppen Cwa) — Northern Hemisphere, latitude 23.2°N — which shapes how much energy it can produce and how its output varies through the year.
Monthly mean temperature
Heating degree-days here run 86% 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: 18/100 — this site sits in the bottom third of the power plants we cover by heating degree-days.
In colder climates, uninsulated hot equipment (boilers, turbines, valves, steam lines) loses proportionally more heat to ambient air — exactly the loss Inzonex modular insulation is designed to cut.

The #15 largest coal power plant of 1434 in China by capacity.
China has 1434 coal power plants in this dataset, together about 1,249,175 MW of capacity.
