The City Council of León has taken an important step towards a more sustainable urban model with the implementation of a energy self-consumption system which will significantly reduce municipal electricity costs. The new infrastructure, based on photovoltaic generation and battery storage, will allow for cuts of around 620.000 euros per year from the City Council's electricity bill.
This project, which the government team itself describes as pioneer at the local levelIt combines economic and environmental objectives: on the one hand, it reduces the administration's structural costs, and on the other, it cuts polluting emissions and dependence on fossil fuels. The City Council emphasizes that committing to this solar energy It is a form of improve energy security and well-being of citizenship.
A 2,5 million investment with European backing
The self-consumption strategy implemented in León is based on a total investment of approximately 2,5 million euros, of which approximately One million is co-financed by the European UnionThese European funds make it possible to promote a network of renewable installations that fits with EU energy transition policies and the Sustainable Development Goals.
With this economic injection, the following projects have been carried out: different projects to equip municipal buildings with self-generation of clean energyThe objective is twofold: to reduce the City Council's energy bill and to move towards a more efficient model, less exposed to the volatility of electricity prices and with lower carbon footprint.
According to data provided by the City Council, the entire system will allow the production of approximately 3,9 million kWh per year of renewable electricity. This volume of generation represents a significant portion of municipal electricity consumption and will result in a significant reduction in greenhouse gas emissions.
The mayor of León, José Antonio DiezShe argued that this energy strategy aligns with the commitment to building a “more efficient, sustainable, and future-proof” city. During the project presentation, she emphasized that investing in photovoltaics is not only an environmental issue, but also a way to contain public spending in the medium and long term.
Network of 13 solar installations with batteries
The core of the action is the creation of a network of 13 photovoltaic solar installations located in various municipal buildings and facilities. Of these, Ten incorporate energy storage systems using batteries., a key element to increase energy efficiency and reduce dependence on the grid during hours without sunlight.
Together, these facilities add up to a total power of 1.538,68 kWp, accompanied by a storage capacity of 1.970 kWhThanks to this infrastructure, the energy generated can be distributed to more than 100 municipal consumption points, with a range that can reach up to five kilometers from each generation site.
From a technical point of view, municipal officials and representatives of the collaborating companies have highlighted that this shared self-consumption scheme reinforces the robustness of the local electrical systemBy dispersing generation and combining it with storage, flexibility is gained and vulnerability to peak demand or network incidents is reduced.
The infrastructure is designed to be progressively integrated with other photovoltaic installations already existing or under construction in various public buildings throughout the city. In this way, León is developing a kind of municipal "solar network" that aims to position the city among those making the most progress in self-consumption at the local level in Spain.
In addition to the mayor, the following people spoke at the project presentation: Jesus Garcia Florez, responsible for Electrical Services of the City Council, as well as Alfonso Escuredo (Kstar) and Martín Zaldo (Norsol), companies involved in the technical development. Their explanations focused on the role of batteries and the importance of correctly sizing the installed capacity to maximize the economic and environmental return.
2.481 panels in the first phase and almost 5.000 more underway
The first phase of this strategy involves the installation of 2.481 solar panelswhich contribute a combined power of around 1.538 kWThese modules have been distributed in different parts of the city, prioritizing buildings with significant energy consumption and roofs suitable for housing photovoltaic installations.
Among the selected locations, the following stand out: pergola of the Paseo de los Pendones Leoneses —structure that covers the urban and metropolitan bus interchange— and several municipal sports halls: San Esteban, Margarita Ramos (in Polígono 10), La Torre and the one located next to the Luis Vives school.
The following have also been added to the network: Cleaning Service facilities, the sports centers of public schools The Farm and Quevedo, the West Sales Civic Center and the Social Action Center (CEAS) Ventas EsteThe list is completed by the pavilions of Castro BridgeGumersindo Azcárate and Salvio Barrioluengo, who are expanding the coverage of renewable energy generation in several neighborhoods of the city.
These 2.481 plates are in addition to some almost 5.000 additional, already installed or under construction, which provide an extra power of approximately 1.637 kWThese other facilities are spread across iconic locations such as the Palace of exhibitions and congresses, the municipal building of Ordoño II, La Palomera swimming pools, the Fire station and the Railway Orphans' School (CHF), among others.
The choice of these locations is not accidental: these are spaces with significant energy consumption throughout the year, where the installation of solar panels can have a direct impact on the electricity bill and help stabilize supply-related costs. Furthermore, the visibility of these facilities contributes to normalize solar energy in the urban landscape of León.
Expected savings, return on investment and emissions reduction
One of the facts that the City Council emphasizes most is the estimated economic savings of more than 620.000 euros per year on the municipal electricity bill. With these figures on the table, the City Council calculates that the amortization of the investment achieved in this first phase could reach around three yearsprovided that generation and consumption forecasts are maintained.
Beyond the economic component, the project has significant environmental implications. The combination of photovoltaic generation and storage will allow to avoid the emission of more than 860 tons of CO₂ per yearThis represents a significant contribution to the fight against climate change at the local level. This emissions reduction aligns with European climate strategies and the national roadmap for decarbonization.
The self-consumption scheme designed for León also seeks to smooth the City Council's exposure to the volatility of the electricity marketBy having a significant portion of its energy consumption covered by its own energy sources, the City Council gains flexibility in the face of price increases and reduces budgetary uncertainty linked to the cost of electricity.
On a social level, the initiative is presented as a practical example of how a local administration can lead the energy transition in its territory. The implementation of this system in public buildings reinforces the message that solar energy is not only an option for homes or private companies, but also for community facilities and basic services.
Overall, the operation places León on the map of Spanish cities that are making a firm commitment to the self-consumption at the municipal levelThe combination of own funds and European funding, along with a network of facilities spread throughout the urban area, outlines a model that could serve as a reference for other municipalities that want to reduce costs and emissions without sacrificing the quality of public services.
With this network of solar panels, battery systems, and a design conceived to maximize the use of clean energy, León is moving towards a more efficient city, less dependent on the conventional grid, demonstrating that municipal energy self-consumption It can be a useful tool for saving money, cutting emissions, and strengthening resilience against future energy challenges.
