Global Energy Monitor’s Global Gas Plant Tracker (GGPT) uses a two-level system for organizing information, consisting of both a database and wiki pages with further information. The database tracks individual gas plant units and includes information such as plant owner and parent company, plant status, plant type, and location. A wiki page for each power station is created within the GEM.wiki, and contains more detailed, footnoted information such as project history and public opposition. The database and wiki pages are updated bi-annually, in February and July.
The GGPT tracks all gas-fired power plants that generate electricity in any setting (i.e. peaking and base load generation, captive industrial plants, and co-generation). It includes units with capacities of 50 megawatts (MW) or more (20 MW or more in the European Union and the United Kingdom). For combined cycle units, the capacity threshold is applied to the entire combined cycle set and not to the individual components. The tracker does not include plants running on recaptured/waste gas, gas boilers only generating district or industrial heat, plants running on only liquid fuels, or plants that rely on internal combustion engines.
Announced: Projects that have been publicly reported but have not yet moved actively forward by applying for permits or seeking land, material, or financing.
Pre-Construction: Projects that are actively moving forward in seeking governmental approvals, land rights, or financing.
Construction: Equipment installation has begun (not just clearing/roads).
Shelved: Two years have passed with no action on a project after the project proposal.
Cancelled: A cancellation announcement has been made, or no progress has been observed for at least four years.
Operating: The plant has been formally commissioned; commercial operation has begun.
Mothballed: The plant is not in use (no operation for more than 1 year) but not dismantled.
Retired: The plant has been dismantled; this term is also used if the plant has been destroyed by war.
The Global Gas Plant Tracker data set draws on various public data sources, including:
- Government data on individual power plants, country energy and resource plans, and government websites tracking gas plant permits and applications;
- Reports by state-owned and private power companies;
- News and media reports;
- Local non-governmental organizations tracking gas plants or permits.
A partial list of data sources can be found here.
Global Energy Monitor researchers perform data validation by comparing our dataset against proprietary and public data such as Platts World Energy Power Plant database and the World Resource Institute’s Global Power Plant Database, as well as various company and government sources.
Carbon Dioxide Emissions
For each gas plant unit, the tracker calculates annual and lifetime carbon dioxide emissions. Further details including parameters and sources can be found at Estimating Carbon Dioxide Emissions from Gas Plants on GEM.wiki.
For each gas-fired power plant, a wiki page is created on Global Energy Monitor’s GEM.wiki. Wiki pages provide a repository for in-depth information including project background, financing, environmental impacts, public opposition, coordinates, and maps. 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.
