Global Energy Monitor’s Global Nuclear Power Tracker uses a two-level system for organizing information, consisting of both a database and wiki pages with further information. The database tracks individual nuclear power plant units and includes information such as project owner, status, reactor type, and location. A wiki page for each project is created within the Global Energy Monitor wiki. The database and wiki pages are updated annually.
Announced: Proposed projects that have been described in corporate or government plans but have not yet taken concrete steps such as applying for permits.
Pre-construction: Projects that are actively moving forward in seeking governmental approvals, land rights, or financing.
Construction: Site preparation and equipment installation are underway.
Operating: The project has been formally commissioned.
Shelved: Suspension of operation has been announced, or no progress has been observed for at least two years.
Mothballed: The project is disused, but not dismantled.
Retired: The project has been decommissioned.
The Global Nuclear Power Tracker data set draws on various public data sources, including:
- Industry data on individual nuclear power units
- Government websites tracking project permits and applications
- Reports by power companies (both state-owned and private)
- News and media reports
- Local non-governmental organizations tracking nuclear projects or permits

Global Energy Monitor researchers perform data validation by comparing GEM’s dataset against proprietary and public data such as S&P Global’s World Electric Power Plant Database (WEPP) and the World Resource Institute’s Global Power Plant Database, as well as various company and government sources.
For each nuclear power project, a wiki page is created on Global Energy Monitor’s wiki. Under standard wiki convention, all information is linked to a publicly-accessible published reference, such as a news article, company or government report, or a regulatory permit. In order to ensure data integrity in the open-access wiki environment, Global Energy Monitor researchers review all edits of project wiki pages.
