Neither dataset records data centres or other electricity demand. Projects that are small, unreported or filed after the published dates do not appear.

QueueLedger reports public EIA and Lawrence Berkeley National Laboratory records of planned generators and interconnection requests near an address. It is not a utility, a developer, a regulator, an appraiser or a legal advisor, and a report says nothing about whether any project will be approved, built or cancelled.
