Hunterston nuclear power plant in context
The 4 units with both construction and grid dates on record took 6.3 to 9.4 years (median 7.5) from construction start to grid connection; the median across all reactors connected in the 1970s is 5.4 years.
The nearest other tracked nuclear sites are Torness nuclear power plant (158 km), Heysham nuclear power plant (227 km) and Hartlepool nuclear power plant (265 km).
Build time by unit
| Unit | Construction start | Grid connection | Years | Fleet median, same decade |
|---|---|---|---|---|
| Unit A1 | 1957 | 1964 | 6.3 | 5.0 (1960s) |
| Unit A2 | 1957 | 1964 | 6.7 | 5.0 (1960s) |
| Unit B1 | 1967 | 1976 | 8.3 | 5.4 (1970s) |
| Unit B2 | 1967 | 1977 | 9.4 | 5.4 (1970s) |
Nearest tracked nuclear sites
| Site | Country | Distance | Operating GW gross |
|---|---|---|---|
| Torness nuclear power plant | United Kingdom | 158 km | 1.4 |
| Heysham nuclear power plant | United Kingdom | 227 km | 2.6 |
| Hartlepool nuclear power plant | United Kingdom | 265 km | 1.3 |
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.
| Location | Scotland, United Kingdom |
|---|---|
| Coordinates | 55.7200, -4.8975 |
| Elevation | about 5 mabove sea level |
| Setting | On the sea coast, 0.2 km from the water |
| Region | Northern Europe |
| Units by status | Retired: 4 |
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.
