Data & Methodology
World Power Plants is an independent reference database covering more than 40,000 power generation facilities in 160+ countries, published in 27 languages. Every figure on this site — installed capacity, fuel type, commissioning year, operator — is traceable to a documented source.
This page explains where our data comes from, how it is verified, and how it stays up to date.
Primary data sources
Our foundation is the Global Power Plant Database (World Resources Institute), extended and continuously reconciled with the Global Energy Monitor trackers, Wikidata, national grid operators and statistical offices, and the reports of the IEA, IRENA and the U.S. EIA. Live grid figures come directly from official system operators such as ENTSO-E, EIA, AEMO, ONS and IESO.
How records are verified
No external change is written directly to the database. Every proposed update — a capacity revision, a new plant, an ownership change — enters a review queue where it is cross-checked against at least one independent source before an editor approves it. Unrealistic values are rejected automatically, and each plant page shows when its record was last verified and from which source.
How the site stays current
The database is updated continuously: nightly synchronisation runs compare our records with the latest published figures, and corrections also reach us from readers and supporters around the world who follow their local energy markets in their own languages. Reader reports are reviewed through the same verification queue as every other change.

Frequently asked questions
Where does the data on World Power Plants come from?
From documented public sources: the Global Power Plant Database, Global Energy Monitor, Wikidata, national grid operators, and IEA/IRENA/EIA publications. Live generation data comes directly from official system operators.
How often is the database updated?
Continuously. Automated synchronisation runs nightly, editors review the change queue daily, and live grid pages refresh within minutes. Each plant page displays its last verification date.
Can I use or download the data?
Yes — the underlying data is available under the CC BY 4.0 licence with attribution to WorldPowerPlants.com. Country-level lists can be downloaded as CSV from each country page.
How do I report a mistake?
Through the contact form. Include the plant name and a verifiable source; corrections go through our standard verification queue and are usually published within days.
