Seoul Smart Streetlight Deployment: Verified Budget and Scope
Why this case matters for urban IoT planning
A streetlight project is no longer just a lighting purchase. In this verified SOLARTODO case study, the asset becomes a multi-service urban node: illumination, surveillance, public communication, charging, and centralized control are all packaged into one pole-based architecture. For procurement teams and EPC integrators, the key value is the exact commercial and technical scope behind the $126,989 turnkey figure.
Project scale and pricing tiers
This deployment covers 37 poles along a 1,800m road with 50m spacing and 12m smart poles. The pricing ladder is fixed and useful for procurement comparisons: $82,543 FOB, $101,591 CIF, and $126,989 turnkey. The system is specified at 1,110,000 total lumens, with 200W LED luminaires and a calculated 490W per pole electrical load. Annual energy use is 66,175 kWh, and daily consumption is 181.3 kWh.
| Commercial scope | Value |
|---|---|
| FOB price | $82,543 |
| CIF price | $101,591 |
| Turnkey price | $126,989 |
| Road length | 1,800m |
| Pole count | 37 |
| Total lumens | 1,110,000 |
Technical Architecture and Integrated Functions
Networked control model
The control layer uses 1 controller for 37 poles, which is a practical NMS-style architecture for centralized commissioning, fault detection, and remote monitoring. This is the kind of structure often discussed in smart-city references from the IEA, which notes that digital technologies are becoming increasingly important for energy security, resilience, and affordability. In other words, the communications layer is not optional; it is part of the infrastructure value.
Pole-level service integration
Each pole in this configuration includes 37 cameras, 37 LED displays, 37 IP speakers, 37 wireless chargers, and 37 EV chargers. The EV charging element is specified as 7kW per unit, and the design can also be mapped to a 11kW EV Type 2 charger streetlight concept where higher charging throughput is required. For advanced urban corridors, the same platform can be adapted into a 5G NR n78 ready smart pole or even a CIGS thin-film wrapped pole 200W concept when solar-assisted variants are needed.
Operating Economics and Procurement Implications
Cost structure and ROI reality
The annual operating cost is $15,581, split into $7,941 electricity and $7,640 maintenance. The verified payback period is 156.7 years, which is a clear signal that this configuration should be evaluated primarily as a public-infrastructure and service-integration asset, not as a short-term energy ROI play.
What buyers should extract from the case
For municipal buyers, the important lesson is that SOLARTODO’s architecture bundles lighting, sensing, communication, and charging into one standardized street platform. That reduces fragmented procurement and makes lifecycle management more transparent. It also aligns with broader electrification guidance from IRENA and system-planning practices highlighted by NREL.
Practical takeaway for Seoul-style deployments
Use the verified numbers as a baseline
If your team is benchmarking a Seoul-style smart corridor, use the exact commercial tiers, pole count, energy profile, and integrated device counts above as the starting point. The verified record is valid through 2026-05-05, and the project context is listed as Global / 협의.
