Evidence and method

reported · directA compilation of transmission providers' interconnection queues in one schema, as each provider published them and as LBNL and GridTracker cleaned them: a request for interconnection service, not a plant, with the provider's own status text kept beside LBNL's status, and with agreement, operation and withdrawal dates only where the provider publishes them. Requests sited in WA, OR, ID and MT are loaded; the compilation lags the providers' own queues by months, so an active request here can have changed since. MW are the requester's figures and never enter capacity totals. Rows carrying BPA's request numbers are candidates for the same request in BPA's own workbook and are never merged with it.

Evidence and method

reported · directA queue request is a request for interconnection service, not a plant: many requests can describe one facility, requests are withdrawn or restudied, and an energized request does not name the operating plant. Request numbers and study milestones are BPA's; nameplate and interconnection MW are the requestor's figures. No location beyond county and the named point of interconnection.

Publisher

LBNL and GridTracker publish Queued Up as editions, each a report and one data file, and state on the page when the current file was last updated and how far its data runs. BPA links its Interconnection Request Queue workbook on its interconnection page and states no update schedule; the workbook's own header carries the timestamp it was generated.emp.lbl.gov/queues ↗www.bpa.gov/energy-and-services/transmission/interconnection ↗

Delay

On the checked date LBNL's page said the data file was last updated in May 2026 with interconnection data through the end of 2025, and that the report was published in June 2026. BPA's page states no delay; the acquired workbook's generation timestamp is its edition.emp.lbl.gov/queues ↗www.bpa.gov/energy-and-services/transmission/interconnection ↗

This atlas

The atlas pins one LBNL data file and one BPA workbook by hash, named under edition; a changed hash is a new edition adopted as a release decision. No timed refresh.emp.lbl.gov/queues ↗www.bpa.gov/energy-and-services/transmission/interconnection ↗
