Methodology & sources

Counts aggregate current canonical project records whose market region is MISO. Status is normalized to a five-value vocabulary (active, operational, withdrawn, suspended, unknown).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 Withdrawn and operational projects are retained as historical records.

Source last checked2026-07-31
Data last materially changed2026-10-11
Page data generated2026-10-11

Provenance: U.S. EIA — Form EIA-860M generator inventory (operating + planned); 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.
