“Retrieved by Radar” is when we obtained the source for this review. “Public-source check date” applies only to the facts cited here. Neither date means the project itself changed or independently verifies every field.

Member research: available contractors and engineers, exact reported values and capacity evidence, detailed sources and permitting history, plus tracker CSV export. Availability and verification vary by record.

Latest review attempt: Oct 10, 2026 — inconclusive. The review did not resolve every question; the prior research check date is retained.

The historical date comes from the original workbook. It is not a newly completed source check.
