A power-feasibility call is only worth the track record behind it. So every screening verdict here is timestamped, and scored against what actually happens in the field. This page is the public scoreboard - and the realized base rates that anchor it.
When a site is screened we record the coordinate, the inputs (MW, timeline), the verdict (ADVANCE / CAUTION / KILL), the fastest path and its month estimate, and the timestamp. A verdict is later marked:
Hit - the realized outcome fell inside our stated band (e.g., we said on-site ~22 mo and it energized within the screening tolerance; or we said KILL and the grid did arrive far outside the window).
Miss - reality fell outside the band. We publish the gap and the reason, and feed it back into the model.
Outcomes are confirmed from primary records - ISO/utility energization filings, operator disclosures, and verified developer reports - each with a source, the same way every number in the tool is sourced.
Until our own track record matures, the most honest anchor is the realized record for the whole U.S. grid. These are not our estimates; they're measured outcomes for completed projects:
| Realized metric (completed projects) | Value | Source |
|---|---|---|
| Median time, interconnection request → energized | ~4.5 years (projects reaching operation in 2024) - up from under 2 years in 2000-07 | LBNL “Queued Up”, 2025 Ed. |
| Share of queued projects that withdraw before connecting | ~80% | LBNL “Queued Up”, 2025 Ed. |
| Average months in queue - CAISO / ERCOT / PJM | ~43 / ~22 / ~24 months | American Clean Power (2023) |
These same realized figures now appear inside every verdict, beside our modeled grid date, as a reality check.
Market- and utility-specific realized timelines don't exist cleanly anywhere - they live in tribal knowledge and scattered filings. We're assembling them two ways:
1. Completed-project mining. Realized request-to-energized durations computed from ISO/RTO queue records and LBNL data, market by market.
2. Verified developer contributions. Operators submit a real deal's timeline (applied date, energized date, utility) with evidence; we verify the source before it counts. Contributors are credited. Unverified claims never enter the dataset.
Every verified outcome and every scored prediction makes this record harder to replicate - that compounding accuracy is the asset. Screen a site →
