Las Rozas completes its Energy Self-Consumption Plan: Over 3,000 solar panels installed across 30 municipal buildings

All data gathered is integrated in real time into the city's Smart City Platform, enabling monitoring of both energy production and consumption

The Las Rozas City Council has reached one of the major milestones in its strategy as a smart city and a benchmark in energy efficiency. The city has just taken a huge step forward in its Energy Efficiency Plan, successfully completing the project—launched in 2023—to install solar panels across all municipal buildings. This comprehensive project, carried out by Las Rozas Innova, the Municipal Company for Innovation and Technological Development, has brought solar energy to 30 municipal buildings, with more than 3,000 photovoltaic panels now generating 2.4 gigawatt-hours a year, equivalent to the annual consumption of 700 households.

With this milestone, Las Rozas ranks among one of the first cities in Spain to achieve full solar coverage of its public infrastructure, reinforcing its leadership in sustainability, innovation, and the energy transition.

This is a project that Las Rozas City Council, through Las Rozas Innova, has carried out over three years, divided into two phases. In the first phase, which began in summer 2023, 1,800 photovoltaic panels were installed across all municipal schools and sports centres: 11 public schools and 4 sports facilities. 

In the second phase, which has just been completed, 1,200 photovoltaic panels have been installed at another 15 municipal facilities, including the City Hall, the El Abajón Municipal Centre, El Baile and Las Matas senior centres, the Las Matas Civic and Social Centre, SAMER-Civil Protection and Local Police headquarters, La Cigüeña María and Juan Ramón Jiménez nursery schools, Joaquín Rodrigo Auditorium, León Tolstoi, Ortega y Gasset and Marga Gil Roësset libraries, as well as, Youth Centre and Pérez de la Riva Cultural Centre.

A more sustainable and efficient city

"With the completion of this major municipal building self-consumption project, we continue moving toward our goal of turning Las Rozas into a more efficient, innovative and sustainable city. Thanks to Las Rozas Innova, we are not only generating clean energy but also applying technology to management, thereby cutting costs, reducing emissions and improving the services we provide to residents," said the Mayor of Las Rozas and Chairman of Las Rozas Innova, José de la Uz, who has visited the solar installation at León Tolstoi Library together with Rafael García, Deputy Minister for the Environment of the Madrid Region. 

The results obtained to date further confirm the project's positive impact. On average, municipal buildings are already saving 30% on energy costs thanks to an investment of close to 2 million euros made over the past three years. In addition, the Public Building Self-Consumption Plan will help avoid the emission of approximately 600 tons of CO₂ per year, a reduction equivalent to the absorption capacity of nearly 30,000 trees, directly contributing to the municipality's climate goals.

Las Rozas Public Building Self-Consumption Project is part of the city's Energy Efficiency Plan, which also includes a series of other energy-related actions carried out by the Department of Infrastructure and Public Works that will allow the municipal coffers to save two million euros in 2026. Notable actions include the analysis and monitoring of all consumption (water, gas and electricity) at public facilities, and the modernization of municipal infrastructure, outdoor lighting and the lighting of sports facilities and municipal buildings.

Smart management and real-time monitoring

One of the key differentiators of the Public Building Self-Consumption Plan is the integration of all data from the photovoltaic installations into the Las Rozas Smart City Platform, which enables Las Rozas Innova, as the city's energy manager, to monitor both energy production and consumption across all municipal buildings in real time. This information facilitates energy audits, the analysis of consumption patterns and the identification of new savings and efficiency opportunities, optimizing the management of public resources through advanced technological tools.

A comprehensive strategy to reduce the carbon footprint

Las Rozas Energy Efficiency Plan is part of the City Council's strategy known as Las Rozas Objetivo Cero 2030 (Net Zero Target 2030), which brings together initiatives carried out by the various areas of the municipal government and Las Rozas Innova aimed at reducing the city's environmental footprint, such as the Sustainable Urban Mobility Plan (SUMP), Las Rozas Recarga the public charging network for electric vehicles of Las Rozas, the renovation of street lighting with LED technology, the reforestation of natural areas, and smart climate control and irrigation systems. Thanks to this combined set of actions, the municipal carbon footprint has already been reduced by more than 67%.
