Taishan nuclear power plant is a 5,800 MW nuclear power station in Guangdong, China. It is operated by Taishan Nuclear Power Industry Investment Co Ltd [100%]. Based on its capacity (estimated), it can supply roughly 13 million homes (estimated). It ranks #43 of 6,685 China power plants by installed capacity. Commissioned in 2018, it is around 8 years old — recently built. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, nuclear supplies about 4.6% of China's electricity; the national grid averages 525 gCO₂/kWh (41.7% low-carbon) (2025).

The public capacity above is the current source-record value. A 2026 tracker candidate lists 3,500 MW for Taishan nuclear power plant, but it is not used as the public primary value until scope is verified (unit vs operating vs installed/project total).
The capacity and fuel fields on this page are source-record values from the upstream open dataset. They are useful for identification and ranking, but they have not been upgraded to a 2026 registry/GEM-location verified value.

At 5,800 MW, Taishan nuclear power plant is well above the median nuclear plant in China (5,000 MW). Technically it is described as pressurized water reactor. Nuclear plants split uranium to raise steam with no direct CO₂; they run as steady baseload with very high capacity factors and the longest operating lifetimes of any thermal plant.

This nuclear plant uses heat from nuclear fission to raise steam for a turbine-generator. It sits in a humid subtropical (dry winter) climate (Köppen Cwa) — Northern Hemisphere, latitude 21.9°N — which shapes how much energy it can produce and how its output varies through the year.
Climate zone & typical temperatures: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid).
For a plant’s outdoor hardware — heat-recovery steam generators (HRSG), expansion joints, valves, flanges and their insulation — the local climate sets how fast unprotected steel and coatings degrade. This site sits in an aggressive, high-corrosion environment (estimated ISO 9223 class C5 — Very high), with marine salt corrosion the leading environmental stress.
Higher environmental severity is exactly where protective removable insulation pays back most: a sheltered micro-climate slows corrosion, UV and thermal-cycling damage and extends outdoor hardware service life. This is an indicative site-climate context — not a condition assessment of any specific plant or operator.
Indicative estimate via the ISO 9223:2012 informative method (atmospheric corrosivity from temperature, time-of-wetness and airborne salinity), using WorldClim climate normals, the Köppen-Geiger class and coast distance. Indicative, not a measured corrosion rate.
The #26 largest nuclear power plant of 72 in China by capacity.
