Global CCGT & HRSG Fleet Inventory with measured US efficiency & CO2-intensity

A harmonised single-table inventory of 2,813 combined-cycle gas turbine (CCGT) power plants worldwide and their heat-recovery steam generators (HRSG) — about 2,067 GW across 134 countries. Each record carries installed capacity, operating company, commissioning year, lifecycle status, number of HRSG units, a CHP flag, gas and steam turbine models where reported, and annual CO2 where available (mostly Climate TRACE modelled estimates; the US EPA / EU ETS subset is regulator-measured, flagged per row in co2_basis). For 458 US plants it adds EIA-860 engineering detail (gas-turbine count, duct burners, HRSG-bypass capability, planned retirement) and US EPA eGRID measured thermal efficiency and CO2-intensity. Compiled and deduplicated from the WRI Global Power Plant Database, Global Energy Monitor (GOGPT), Climate TRACE, US EIA-860 and US EPA eGRID. A cleaned, analysis-ready compilation of open sources — not new primary measurement. Interactive landing: https://inzonex.co.uk/poweratlas/ccgt-hrsg-fleet/ . CC BY 4.0.

A separate snapshot of the live PowerAtlas CCGT page, with 2,292 plants and 10 fields, is published on figshare: 10.6084/m9.figshare.32706747. It holds different rows and fields from this record.
