Global Energy Monitor’s Global Solar 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 solar farm phases and includes information such as project owner, status, and location. A wiki page for each solar farm 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.
Development: 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; commercial operation has begun.
Shelved: Suspension of operation has been announced, or no progress has been observed for at least two years.
Cancelled: A cancellation announcement has been made, or no progress has been observed for at least four years.
Retired: The project has been decommissioned.
Mothballed: The project is disused, but not dismantled.
The Global Solar Power Tracker data set draws on various public data sources, including:
- Government data on individual power solar farms (such as India Central Electricity Authority’s “Plant Wise Details of All India Renewable Energy Projects” and the U.S. EIA 860 Electric Generator Inventory), country energy and resource plans, and government websites tracking solar farm permits and applications;
- Reports by power companies (both state-owned and private);
- News and media reports;
- Local non-governmental organizations tracking solar farms 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.
For each solar farm, 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.
