How this list is made
Every entry cites a public page that supports the sentence describing it, usually the firm's own technical page or a project announcement. A firm we could not source was left off, and the file records which ones and why. Nothing here is generated from the tracker: this is editorial work, and it is separate from the Global Energy Monitor asset data that fills the rest of the site.
