Chashma nuclear power plant in context
By gross operating capacity Chashma nuclear power plant is the 2nd largest of 2 operating nuclear sites in Pakistan, holding 38% of the country's operating capacity, and ranks 120th of 172 worldwide.
Its operating units started up between 2000 and 2017; the median unit is 12.5 years old, older than the median of 9.5 in Pakistan.
The 4 units with both construction and grid dates on record took 5.2 to 6.9 years (median 5.5) from construction start to grid connection; the median across all reactors connected in the 2010s is 5.9 years.
No other nuclear site with an exact position in this dataset lies within 300 km.
Build time by unit
| Unit | Construction start | Grid connection | Years | Fleet median, same decade |
|---|---|---|---|---|
| Unit 1 | 1993 | 2000 | 6.9 | 6.8 (2000s) |
| Unit 2 | 2005 | 2011 | 5.2 | 5.9 (2010s) |
| Unit 3 | 2011 | 2016 | 5.4 | 5.9 (2010s) |
| Unit 4 | 2011 | 2017 | 5.5 | 5.9 (2010s) |
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.
