About PowerAtlas
PowerAtlas is an open atlas and dataset of the world's power plants — fuel, capacity, owner, technology and asset-level CO₂ (measured for the US & EU via EPA/EU ETS, modelled elsewhere via Climate TRACE) — built and published by Inzonex Research.
What this is
A worldwide power-plant backbone (WRI GPPD + Global Energy Monitor) joined with asset-level emissions, climate and corrosivity layers, so each plant page answers a specific, verifiable question. In the current live atlas build, the usable asset-level CO₂ subset contains 4,155 records: 1,157 regulator-measured US EPA / EU ETS records (28%) and 2,998 modelled Climate TRACE records (72%). Calculated fuel-factor estimates, emission intensities and ISO 9223 corrosivity are labelled separately.

What each page contains
Plant pages list per-plant capacity (MW), primary fuel, owner, country/region, coordinates and measured-vs-modelled CO₂ where reported. Country and company pages aggregate these into fleet totals, fuel mix and grid carbon intensity. Every value traces to the open sources below — WRI GPPD, Ember / Our World in Data, EPA / EU ETS and Climate TRACE — under CC BY.
Open datasets (Zenodo, CC BY 4.0)
Zenodo records are versioned citation snapshots. Their row counts can differ from the current atlas build after deduplication, source updates or provenance fixes; cite the DOI when referencing the frozen table, and cite this page when referencing the current web atlas.

Methodology & sources
Physics, fuel/technology resolution, emissions provenance and per-plant climate/corrosivity method are documented on the methodology & sources page. ASTM C680 / ISO 12241 for heat loss; ISO 9223 for atmospheric corrosivity.

Frequently asked questions
Who publishes PowerAtlas?
PowerAtlas is published by Inzonex Research, with dataset work credited to Dmytro Aheiev and linked Zenodo records where available.
Which sources does PowerAtlas use?
The plant backbone comes from WRI GPPD and Global Energy Monitor; emissions are labelled as regulator-measured EPA/EU ETS, modelled Climate TRACE, calculated from fuel factors, or unavailable.
Are all CO2 figures measured?
No. In the current usable asset-level CO2 subset, about 28% are regulator-measured and 72% are modelled. Plant pages keep those labels visible.
How can a data error be corrected?
Send the plant URL and correction evidence to contact@inzonex.co.uk; the source data is corrected and the atlas is rebuilt.
