IluminaSP, São Paulo's public-lighting PPP, replaced 500,000+ streetlights with remotely managed LEDs in under three years — two years ahead of contract, the concessionaire says. Works have run under the municipal lighting PPP since August 2019, and residents can follow the rollout point by point on the city's GeoSampa map. By late 2021 the city counted about 600,000 LED points, roughly 90% of its lighting stock.
what does this mean?
The strongest source is the operator's or the city's own reporting — an official report, dataset or press release. It grades who did the looking — not how well the project went. All four grades →📊 Impact
The concessionaire reports energy use down more than 50% and R$120 million saved in 2023. The city's own published count, in late 2021, was about 600,000 LED points — roughly 90% of São Paulo's lighting stock.
🎓 Lesson
The retrofit was fast and the accounting is in-house. The 500,000-plus luminaires, the halving of energy use and the R$120 million saved in 2023 are all the concessionaire's own figures; the city's own updates stop in 2021, and no independent audit of the savings was found. A lighting PPP buys speed and hands the meter to the party being paid — the one thing São Paulo did keep in public is the map, where each converted light shows up on GeoSampa.

Forensic record — source dossiers, gaps, hashes and the exact revision this page renders
This layer records what is known about each source, what is still missing, and the exact snapshot this page is rendering. A missing date, archive or hash stays visible as missing.
Awaiting operator and domain-expert review; publication of this revision implies neither.
Erratum on this revision's envelope. The snapshot, its hash and its permanent link are untouched.
- createdAt previously read 2026-08-27T05:00:00Z. The batching script that produced this revision advanced createdAt into the future to satisfy the strictly-increasing order the validator requires per entity. The value never recorded a real event; the corrected value is the moment the revision provably existed in the repository. Corrected to 2026-08-26T14:54:36Z on 2026-08-27; evidence: first appears in commit a70cba917d, committed 2026-08-26T14:54:36Z.

Concessionaire running the public-lighting PPP; source for 500,000-plus luminaires, the more than 50% cut in energy use, the R$120 million saved in 2023 and the claim of finishing two years ahead of contract. A continuously maintained company site, so it carries no publication date for those figures.

Known limits of this passport
- Publisher names and source languages have not yet been classified; domains are recorded without guessing.
- Existing source notes are descriptive locators, not page- or paragraph-exact citations.
- A missing archive, publication date or content hash is shown as null rather than inferred.
- The project-level evidence grade ranks the strongest source in the entry; it is not a truth score for every claim.

Who owns the lamppost?
Every city in this group swapped its street lighting for LEDs and put a management system behind it. The difference is who paid, who operates it and for how long — a choice that outlives the lamps.
