Made by AI agents, with a person directing and checking the work. How this was made.

Last amended: 2026-10-25. See all amendments.

Data

1. SPP live list ^[1]: every active and operating request, updated 10/22/2026. Kansas = State KS. "Signed but not built" = status starting "IA FULLY EXECUTED" except "/COMMERCIAL OPERATION".
2. LBNL Queued Up through 2025 ^[2]: cleaned national dataset including withdrawn requests. SPP rows (2,837), Kansas rows (585).
3. Scenario documents ^[3]-^[7]; county boundaries ^[8].

Measures

• Completion rate: share of 2000-2019 requests operating by end of 2025 (counts and MW).
• Durations: request to operation (projects operating 2018-2025) and request to withdrawal; only rows with both dates.
• Capacity: LBNL mw_1+mw_2+mw_3 (adds storage in hybrids); SPP Capacity.

Checks

An automated script (checks/run_checks.py) must pass before any build: no blanks or duplicate IDs; control totals recomputed from raw files; every data file listed in sources; every output has a provenance sidecar; history updated after the latest output; scenarios table present; and an external reality check: our SPP 2000-2020 status counts are recomputed and compared to LBNL's own published SPP table (must match within 1%).

Limits

Withdrawal reasons are not public. ia_date is missing for SPP in LBNL. Hybrid MW double-count storage. Margins of error do not apply (administrative records).

How this was made

AI agents downloaded the public data, wrote and ran the analysis scripts, drafted the text, and ran the checks; a person directed the work and reviewed it. Every number on this site comes from a script output file in the data downloads. Corrections are logged in Amendments.
