Fleet by fuel
Fleet interpretation
Tokyo is represented here as an asset portfolio, not just a company label. The visible fleet spans 1 country; the largest concentration is Japan (28).
The fuel mix by asset count is hydro (10), gas (8), oil (6), nuclear (2). The largest listed asset is Kashiwazaki Kariwa in Japan (7,965 MW), and the mean listed unit size is about 2,112 MW across units with capacity data.
CO₂ coverage is source-labelled: 2 plants have a reported or modelled CO₂ value in the dataset, including 0 measured records. Missing values remain blank rather than inferred as company totals.
Method: plant-level records are grouped by owner/operator label, then aggregated by country, fuel, capacity and CO₂ provenance.
