Tohoku operates 15 power plants across 1 country, with a combined installed capacity of 16,242 MW. Its plants with asset-level emissions data total 31,192,110 t CO₂/yr.
Tohoku is represented here as an asset portfolio, not just a company label. The visible fleet spans 1 country; the largest concentration is Japan (15).
The fuel mix by asset count is gas (5), geothermal (4), nuclear (2), coal (2). The largest listed asset is Higashi Niigata in Japan (4,810 MW), and the mean listed unit size is about 1,083 MW across units with capacity data.
CO₂ coverage is source-labelled: 7 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.
