SPP Interconnection Queue
The Southwest Power Pool (SPP) administers the interconnection queue across the central Great Plains, from the Dakotas to Oklahoma.
The interXdata canonical warehouse currently tracks 10 interconnection requests in the SPP footprint, representing 3,409 MW of requested capacity. Of these, 4 are active and 1 have reached commercial operation.

Methodology & sources
Counts aggregate current canonical project records whose market region is SPP. Status is normalized to a five-value vocabulary (active, operational, withdrawn, suspended, unknown). Capacity is the primary requested MW per project. Withdrawn and operational projects are retained as historical records.
Provenance: Lawrence Berkeley National Laboratory — Queued Up interconnection dataset. Values are normalized from public source records into the interXdata canonical warehouse; see each source for original filings.
