Smart Streetlights in South America: Where Is the Money Being Wasted?
There is one statistic that warrants serious attention from every project stakeholder.
According to research data from the World Bank, electricity costs for street lighting in South American cities account for anywhere between 10% and 40% of the total municipal energy budget—depending on the efficiency and quantity of the fixtures.

The sheer magnitude of this range highlights a fundamental issue: most cities have absolutely no idea where their money is actually going, let alone which expenditures could be avoided.
When smart streetlights were first introduced to South America, the underlying logic was sound: replace manual inspections with digital management, and substitute fixed-output operation with remote dimming, thereby systematically reducing operating costs. However, what we are now observing in some projects is the exact opposite outcome—systems are becoming increasingly expensive, maintenance is becoming more difficult, and budgets are being stretched ever thinner.
The problem does not lie with the "smart" concept itself, but rather with the fact that money is being spent in all the wrong places.
The First Wasted Expenditure: Paying for Non-Existent Needs
Many smart streetlight projects are already over-engineered right from the bidding stage.
Standard configurations often include environmental monitoring sensors, pedestrian flow counting modules, and even AI edge computing nodes. While these features may have a legitimate place in smart city projects in Europe or the Gulf states, in the actual operational environment of a mid-sized South American city, the data they generate goes unprocessed, the associated costs go unaccounted for, and the technical faults they inevitably develop go unrepaired.
Numerous assessment reports on public infrastructure projects in Latin America, conducted by the Inter-American Development Bank (IDB), point to the persistent mismatch between project planning and actual operational capacity as one of the core structural causes of project failure.
In other words: purchasing features you cannot utilize is tantamount to writing a check to cover future maintenance and repair bills.
The Second Wasted Expenditure: Paying for Uncontrollable Platform Dependency
The control systems for smart streetlights represent one of the most common sources of runaway operating costs.
When a city selects a specific vendor's proprietary management platform, it is effectively signing a long-term contract: all future system upgrades, fault diagnostics, and software licensing requirements must be channeled back through that same vendor.
This type of dependency is manageable in markets like North America and Europe, where robust technical competition and contractual enforcement mechanisms are in place. In South America, however, local governments typically find themselves in a weaker negotiating position, facing prohibitively high switching costs and extremely limited exit options. In its series of analyses regarding public infrastructure investment in Latin America, the IDB has explicitly emphasized the critical importance of open interface standards and modular designs with interchangeable components as prerequisites for initial procurement. The core rationale behind this approach is to mitigate the long-term cost risks associated with "technology lock-in"—the state of being confined to a single vendor's proprietary ecosystem.
The Third Unnecessary Expenditure: Paying for Unmaintainable Complexity
It is a well-known structural constraint that operations and maintenance (O&M) teams in South American cities typically operate with limited personnel.
Given this premise, if troubleshooting a smart street lighting system requires an on-site visit by a specialized engineer, remote support from the manufacturer, or a lengthy waiting period for imported spare parts, then every minor technical glitch risks being amplified into a major financial burden.
The Inter-American Development Bank (IDB), in a street lighting energy-efficiency loan project approved for Bolivia in February 2024 (totaling $35 million; Project ID: BO-L1230), explicitly listed "strengthening the public lighting system management capabilities of municipal autonomous governments" as its second core objective. The logic underpinning this objective is precisely this: the failure of numerous systems in the past was not due to flawed technology, but rather because local maintenance capabilities failed to keep pace with the complexity of the systems deployed.
So, where should the funds actually be directed?
Candidly, the procurement philosophy for smart street lighting in the South American market needs to shift from a focus on "feature scoring" to a comprehensive "Life Cycle Cost Analysis" (LCCA).
Three key areas warranting priority allocation of funds are:
1. The Reliability of the Lighting Fixtures Themselves:
LED luminous efficacy, Ingress Protection (IP) ratings, and the lifespan of power drivers—these parameters directly determine energy consumption and failure rates, serving as the fundamental variables that underpin the entire project's operational costs.
Data from multiple municipal street lighting PPP projects undertaken by the World Bank in Brazil indicate that LED technology can achieve energy savings ranging from 40% to 70%; when integrated with basic intelligent control systems, some projects have even reached savings of up to 80%.
2. The Standardization of Basic Control Capabilities:
Remote switching, scheduled dimming, and basic fault alerts—these three functions are sufficient to cover the vast majority of daily O&M scenarios. Furthermore, they rely on mature technologies, feature open interfaces, and are maintainable locally. This represents the core investment for optimizing operational costs—and, ironically, the most easily overlooked yet correct choice.
3. Provisioning for Expansion Module Interfaces—Rather Than Pre-installation:
Cameras, LoRa (Low-Power Wide-Area Network) nodes, and environmental sensors—while these features possess genuine market value, they should not be mandated as part of the initial system configuration. Reserving structural provisions and interface ports—and gradually layering on additional capabilities in response to the actual needs of a specific city—represents the only approach that aligns with sound financial logic.
A Reference Case Worth Noting
The public street lighting PPP project in Belo Horizonte, Brazil, stands as one of the largest recorded municipal street lighting retrofit initiatives in Latin America to date. The 20-year contract carries a total value of approximately US$300 million—representing a savings of roughly US$130 million (a reduction of about 30%) compared to the projected expenditure of US$430 million, which was calculated based on historical costs. Crucially, these core cost savings were not achieved through technical downgrading, but rather through system standardization and the redesign of the operational model.
What this case study demonstrates is not that "smart street lighting is too expensive," but rather that "capital can be utilized far more efficiently."
Conclusion
The smart street lighting market in South America is currently maturing; however, the true hallmark of this maturity is not an ever-increasing array of features, but rather the adoption of increasingly pragmatic procurement decisions.
