What the report contains
The workbook's project detail sheets, Large Gen and Small Gen, list each interconnection request by its INR number with fuel, capacity, county and zone, study and agreement milestones, and the projected commercial operation date. ERCOTQueue parses both sheets every month and keeps every report since December 2018.
The report records interconnection requests, not a supply forecast. Projects leave the queue every month.
