Puerto Rico Solar

Provenance, tier, and validation record for puerto-rico-solar. No live curtailment figures on this page — those are on the globe.

Region id: puerto-rico-solar
Country: PRI
Waste modality: Solar
Coordinates: 18.20° N, 66.40° W

Estimated Data quality

Tier

estimated · T3-modelled

No live feed and no published total for this region. A typical-shape profile is scaled to a capacity-based or literature anchor.

Modelled profile, scaled to annual (±40%)

Uncertainty

±40% of peak GW

Published envelope for this tier. See the uncertainty model.

Source provenance

official-lead · Official source identified, live path not producing

An authoritative source exists and the loader is wired or scaffolded, but the live path is not producing usable data — geoblocked, auth-gated, or parser pending. The emitted snapshot falls back to modelled or last-good values.

Source

PREPA operationdata.prepa.pr.gov dataSource.js (utility-scale PPOA solar SiteTotal MW; abed NordVPN relay CSV). Waste unpublished — no curtailment column. EIA-930 has no PR BA. Not T1a.

Tier, provenance, and source are read at build time from src/lib/regions.ts — the same table the globe draws from. The validation record below is generated separately and gated against it by npm run ci:docs-drift.

Discrepancy analysis

Relay lake starts from live dataSource.js snapshots (not EIA-930 — 83 respondents, no PREP/LUMA/CEPR). Until ≥24 distinct timestamps, generationProfile is empty unpublished. Do not read a zero profile as a measured waste finding. Utility-scale PPOA only — not rooftop DG.

Known limitations

See docs/methodology/historical-backfill.md and STATUS.md TSO-grid completeness. Azure mirror is IP-forbidden from NZ; abed NordVPN is the 403 path.
