The Concello de Mos, a municipality of approximately 15,200 residents in Spain’s Pontevedra province, is preparing to launch one of its most ambitious energy modernization initiatives to date. The project encompasses the replacement of 7,000 street lights with high-efficiency LED technology, the renewal of 600 kilometers of electrical cabling, and the upgrade of 220 control panels equipped with remote management capabilities.
Remote Monitoring Capability Enables Centralized Operations
A defining feature of the Mos project is the integration of remote management systems within its upgraded control infrastructure. The 220 control panels slated for modernization will incorporate smart technology enabling municipal operators to monitor, adjust, and diagnose the entire lighting network from a centralized platform.
Remote management systems have become increasingly standard in Spanish municipal lighting projects, allowing operators to switch luminaires on and off remotely, adjust brightness levels based on time of day or traffic patterns, and receive real-time alerts when equipment malfunctions. Neighboring Santiago de Compostela, the regional capital located approximately 95 kilometers north, recently completed a similar smart lighting deployment featuring more than 10,000 NB-IoT connected nodes developed by Tellink in partnership with Telefónica Tech, Ferrovial, and Endesa X. That initiative is projected to deliver energy savings of approximately 55 percent through both LED efficiency gains and dynamic light-level adjustments.
Project Scope Addresses Infrastructure and Sustainability Goals
The Mos initiative extends beyond luminaire replacement to address foundational electrical infrastructure that has aged alongside the municipality’s growth. The 600-kilometer cabling renewal represents a substantial undertaking for a dispersed municipality where residents are scattered across ten parishes rather than concentrated in a single urban center.
Municipal officials have characterized the project as one of the most comprehensive energy modernization efforts in the municipality’s history. The initiative reflects broader Spanish municipal trends toward LED adoption, which according to IDAE (Instituto para la Diversificación y Ahorro de la Energía) analysis delivers average energy savings of 65 percent through reduced power consumption per light point, dropping from approximately 164 watts to 58 watts on average.
Customized Illumination for Cultural and Heritage Sites
The project includes specialized lighting installations for each of the municipality’s ten parishes, with designs tailored to highlight heritage structures, cultural landmarks, and areas of particular social significance. This approach recognizes the distinct identity of each parish while balancing functional illumination requirements with aesthetic considerations.
Such heritage-focused lighting programs have gained traction across Spanish municipalities seeking to enhance nighttime appeal while maintaining energy efficiency. The nearby city of Vigo, which borders Mos and anchors the regional metropolitan area of approximately 545,000 residents, has become internationally recognized for its extensive LED installations.
Public-Private Partnership Model Reduces Municipal Financial Burden
According to municipal statements, the project employs a management model that enables comprehensive modernization without requiring the municipality to fund the entire initial investment. This approach aligns with energy services contracting models increasingly adopted by Spanish municipalities, wherein private partners finance infrastructure improvements and recover costs through guaranteed energy savings over multi-year service agreements.
Such arrangements have proven particularly valuable for smaller municipalities that lack capital budgets for comprehensive lighting overhauls. The European Commission has supported similar street lighting efficiency programs across member states, with funding calls specifically targeting municipal LED retrofits and smart lighting deployments through 2025.
Timeline and Next Steps
The project definition phase has concluded, with municipal officials awaiting publication of the cost structure—a procedural step required before the initiative can advance to plenary council approval. Officials anticipate completing this administrative requirement in April 2026, followed by a formal tendering process. Physical installation work is expected to commence in June 2026.
The timeline positions Mos to join a growing cohort of Spanish municipalities that have modernized public lighting infrastructure under national and European efficiency programs.
