Units
Daya Bay nuclear power plant in context
By gross operating capacity Daya Bay nuclear power plant is the 14th largest of 18 operating nuclear sites in China, holding 3% of the country's operating capacity, and ranks 87th of 172 worldwide.
Its operating units started up in 1994; the median unit is 32.0 years old, older than the median of 10.0 in China.
The 2 units with both construction and grid dates on record took 5.8 to 6.1 years (median 6.0) from construction start to grid connection; the median across all reactors connected in the 1990s is 8.0 years.
The nearest other tracked nuclear sites are Ling'ao nuclear power plant (1 km), Taipingling nuclear power plant (47 km) and Lufeng nuclear power plant (131 km).
2 operating units are rated differently now from their design net capacities: Unit 1 +1.5% and Unit 2 +6.0%.
Build time by unit
| Unit | Construction start | Grid connection | Years | Fleet median, same decade |
|---|---|---|---|---|
| Unit 1 | 1987 | 1993 | 6.1 | 8.0 (1990s) |
| Unit 2 | 1988 | 1994 | 5.8 | 8.0 (1990s) |
Nearest tracked nuclear sites
| Site | Country | Distance | Operating GW gross |
|---|---|---|---|
| Ling'ao nuclear power plant | China | 1 km | 4.2 |
| Taipingling nuclear power plant | China | 47 km | 1.2 |
| Lufeng nuclear power plant | China | 131 km | - |
How these are worked out: ranks use gross operating capacity; ages count from the start-up year on record, as on the age page; build times run from construction start to grid connection, as on the build-times page; ratings are the tracker's net and design net capacity, as on the uprates page. Distances are straight-line between exact positions, so a site with only an approximate position gets none. A unit missing a date or a rating is left out of the figure that needs it.

| Coordinates | 22.5980, 114.5434 |

Elevation is read at the listed coordinates from a 30 m terrain model (SRTM 30 m). Two independent models differ by a median of 6 m across our plants and by up to about 40 m on steep or coastal ground, and a point on a shoreline can read as sea level. Distance to the water is measured to a generalised 1:10 million coastline, so a few kilometres or less is not resolved. This is context, not a design-basis or flood-risk figure.
