DC's Smart Street Lighting Project — billed by officials as the nation's largest urban streetlight P3 — is converting the city's 75,000+ streetlights to networked LEDs with remote monitoring and 239 Wi-Fi access points, under a $309m, 15-year contract with Plenary Infrastructure DC approved by the Council in February 2022.
what does this mean?
The strongest source is press reporting; no primary evaluation was located. It grades who did the looking — not how well the project went. All four grades →📊 Impact
By 2025, officials reported repairs down 49% and energy costs down 70% on lights already converted, with an estimated 38,000 tons of annual greenhouse-gas emissions avoided once the network-wide retrofit is complete.
🎓 Lesson
The figures that justify a fifteen-year contract are measured on the part already done. Repairs down 49% and energy down 70% are reported for lights already converted, mid-rollout, and the emissions saving is an estimate for a network that is not finished - a normal shape for a public-private deal, where the operator reports against its own converted stock and the contract term is the horizon over which those assumptions have to keep holding.

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.
