Tarapur nuclear power plant in context
By gross operating capacity Tarapur nuclear power plant is the 4th largest of 7 operating nuclear sites in India, holding 15% of the country's operating capacity, and ranks 131st of 172 worldwide.
Its operating units started up between 1969 and 2006; the median unit is 21.0 years old, younger than the median of 23.5 in India.
The 3 units with both construction and grid dates on record took 4.5 to 6.1 years (median 5.2) from construction start to grid connection; the median across all reactors connected in the 2000s is 6.8 years.
The nearest other tracked nuclear sites are Kakrapar nuclear power plant (172 km).
3 operating units are rated differently now from their design net capacities: Unit 1 -25.0%, Unit 3 -2.4% and Unit 4 -2.4%.
Build time by unit
| Unit | Construction start | Grid connection | Years | Fleet median, same decade |
|---|---|---|---|---|
| Unit 1 | 1964 | 1969 | 4.5 | 5.0 (1960s) |
| Unit 4 | 2000 | 2005 | 5.2 | 6.8 (2000s) |
| Unit 3 | 2000 | 2006 | 6.1 | 6.8 (2000s) |
Nearest tracked nuclear sites
| Site | Country | Distance | Operating GW gross |
|---|---|---|---|
| Kakrapar nuclear power plant | India | 172 km | 1.8 |
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.

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.
