* marks a capacity figure whose source states a basis other than IT load. Planned MW is IT load unless marked. Running capacity is rarely published, so a missing figure means undisclosed. Cancelled projects are listed and excluded from every total. Definitions, sourcing standards and evidence rules are on the Methodology page. Data is CC BY-NC 4.0. Corrections go to [email protected]. This page is generated from the dataset, so it cannot drift from the map.
