Every Nuclear Power Plant

One row per nuclear power station Wikidata knows: 356 plants across the whole civil atomic age, from Obninsk lighting the first grid in 1954 (Calder Hall and Marcoule two years behind, all three pinned by test) to the units gridded this decade. Each plant carries country, coordinates on 97% of rows, nameplate capacity normalized to megawatts (Kashiwazaki-Kariwa's 7,965 MW is the ceiling of the file and of the world, asserted by test), construction start, grid year, shutdown year, a Status flag and computed years of operation. The two great opposite curves of the industry are both here: Germany appears as 26 plants, all 26 shut down, its exit complete in one column, while China's rows cluster after 2010. One disclosure for country analyses, same as the skyscrapers file: coverage is the graph's and leans toward well-documented Western fleets, so treat per-country counts as Wikidata's attention as much as the industry's census; the within-country stories (Germany's zeroes, Chernobyl's 2000 shutdown, three-quarters of a century of grid years) are honest. 99 plants are shut down, 188 operate, and the Years_Operating column makes fleet-age analysis one groupby away. Built with a 9-test acceptance suite anchored on Obninsk first, Kashiwazaki-Kariwa largest, Germany's completed exit and Chernobyl's final unit.

How big is the Every Nuclear Power Plant dataset?

356 rows in one CSV file, with 13 columns in total: Plant, Plant_ID, Country, Capacity_MW, Units, Construction_Start, Grid_Year, Shutdown_Year, Status, Years_Operating, Latitude, Longitude, Plant_URL.

Where does the data come from?

It is built by programmatically scraping wikidata.org, last pulled on 2026-09-23. Datasets are versioned; older versions stay downloadable.

Is the dataset free to download?

Yes. Every CodeSights dataset is completely free as a CSV download; a free account is all it takes. Anyone can preview the data without signing in.

Can I see the code that built this dataset?

Yes. The exact Python scraper that built it is viewable on the dataset page by any signed-in member, so every number is reproducible.

Can the data contain errors?

Automated scraping leaves room for error and the underlying sources change over time, so no version is guaranteed accurate or complete. If a number matters, verify it against the original source.
