We have all seen in movies those oil lamps or candles lighting the streets of cities, but when is street lighting modernized in Spain? What was the first public tender to manage this facility? In Letter Engineers we recently arrived at Barcelona City Council and we have found very interesting data.
We must go back to the nineteenth century, namely the year 1826, so that in Barcelona lights as street lighting system the first gas lamp. According to historians, it is the first time that the streets are lit enough to not feel unprotected.
The City Council of Barcelona convened in 1841 a public lighting contest won by a French industrial engineer. This one founded two years later the company Catalan Society for gas lighting. We currently know it as Naturgy or, the most backward, by Gas Natural Fenosa. As a curiosity, to comment that the street lighting service comes to Barcelona before running water to homes.
During the twentieth century, with the discovery of electric light, began the decline of gas lights since this new system was much cheaper, comfortable and durable. The gas discharge lamps arrive in which, through electricity, the luminescence phenomenon is achieved. One of the first gases used is mercury vapor which, for those who do not know, emits with a wave in which the ultraviolet predominates. Later improves efficiency in street lighting with the arrival of sodium vapor and its characteristic orange color. A few years ago, and it entered the new century, break into the LED technology in street lighting.
Because of the energy transition we live currently marketing energy undergoes radical changes daily. For more than 20 years, the electricity sector in Spain has been liberalized and, nevertheless, it has not been an effective Law as such. Therefore new models to appear Energy Barcelona have emerged. The council manages the generation and marketing in their own facilities. To generate uses different renewable sources such as photovoltaic and wind. However, it is methane from garbage which it gets its greatest green energy.
In Letter Engineers committed to new energy management models for municipal street lighting. We believe that these new models have a lot to say and here we will be to help them in this difficult way.
“NATIONAL PLAN OF INTELLIGENT TERRITORIES. A strategy for a “smart Spain” that seeks to maximize the opportunities offered by the proper use of digital platforms to provide better public services in the city and in rural areas, and where Letter Engineers has much to offer”
Energy Efficiency: the starting point of an Intelligent Territory
Since 2007, European 20/20/20 targets were established:
- 20% reduction of greenhouse gas emissions (in relation to 1990 levels)
- 20% renewable energy in the EU
- 20% improvement in energy efficiency
In Spain, there have been multiple strategies and announcements, focused on the Energy Efficiency of our towns and cities, since consuming more efficiently helps us to achieve the targets and we also contribute to reduce our Carbon Footprint.
“We have a common challenge: to plan, manage and govern our cities in a sustainable way, maximizing economic opportunities and minimizing environmental damage”
All this has given way to the use of digital platforms able to manage efficiently:
- ENERGY CONSUMPTION OF PUBLIC LIGHTING
- EFFICIENT WATER CONSUMPTION IN THE IRRIGATION SYSTEM OF PARKS AND GARDENS.
- EFFICIENT ROUTES IN WASTE MANAGEMENT
- INTELLIGENT ROUTES IN PUBLIC TRANSPORT
hence, the goal of transforming traditional cities into “SMART CITY”.
To make all of us much clearer, a Smart city is a sustainable and innovative city, since it uses Information and Communication Technologies (ICT) and other means to improve decision-making, the efficiency of operations, the provision of urban services and their competitiveness.
Although it is many steps to go in parallel in Spain it has unveiled NATIONAL PLAN OF TERRITORIES INTELLIGENT, which is part of the digital strategy for Intelligent Spain and it is aligned with the described context and target of the Smart City.
What is a Smart Territory?
The term intelligent territory comes after the peculiarity of our cities and our environment, since the city must be treated as an entity whose boundaries go beyond proper limits. All this is because our cities are included in a much larger area connected to other nearby municipalities.
Another new feature included in this National Plan is the integration of strategy in our rural areas, with the approach of developing a policy named SMART VILLAGES. And it is that 82.8% of the Spanish municipalities are rural and they occupy 72.8% of the total area of the country.
What role does Letter Engineers in the development of Intelligent Territories?
Since the beginning in 2013, LETTER INGENIEROS has opted for technological innovation as an intelligent solution in the energy management of a city or town.
Our team is not only made up of engineers and environmentalists who are experts in energy efficiency, but also supported by the management platforms developed by our Innovation and Development department, composed of computer engineers and experts in the development of applications.
This is the case, for example, of the EFILUX intelligent management platform, which allows the visualization and search of lighting inventory as well as energy management and maintenance.
This platform has been developed with the latest technology to work quickly and efficiently, with a simple, intuitive and clean interface. It also allows to visulise absolutely all the characteristics of any point of light, control center or part of the installation as well as to manage the electronic invoices and to locate disagreements.
Being a management platform of own development allows us to adapt it to the needs of each customer, being functional for another type of management, such as: EFFICIENT MANAGEMENT OF IRRIGATION OF PARKS AND GARDENS, among other functions.
The proposed Telemanagement and Energy Efficiency system will allow a complete management of the maintenance from the control center as well as from the work posts of the maintenance staff, both in their facilities and on the street.
Letter Ingenieros is committed to the smart development of our cities and rural environments as the only solution to sustainable development.
Letter Engineers is awarded the service of management and control of public lighting of the City of Barcelona for 4 years.
Technical Assistance and Management of Public Lighting
The object of the contract is double: to be technical assistance in support of the operation of the control system as well as manage and optimize energy consumption.
Barcelona City Council decided in 2016 for a new centralized control service for its public lighting. The control is based on monitoring and supervision through a platform that integrates all the energy and maintenance aspects. Since 2018 this service will be managed by Letter Engineers and Bettergy, who will work closely with public lighting services of the City Hall. If everything goes well the company intends to be at least until 2022, since it is a contract extendable in 2 + 2 years.
Currently the scope of the contract consists of 2,909 command centers of which 60% of them are remote managed. The vast majority of them communicate with radio technology through 6 receivers, although there is also point-to-point management. In addition, in recent years they have been adding energy-saving measures such as flow regulators and LED lamps with different levels.
One of the most innovative systems in which we are working is the dynamic control of luminosity from lux measurements every 15 seconds. System implemented for years and that will be refined in the next.
Now Letter Engineers manages the public lighting of two of the largest and most emblematic Spanish city halls: Barcelona and Palma de Mallorca. Recall that we were awarded the contract to Palma in 2015 for a total of 4 years ending next year. With all this, the company strengthens and consolidates as the national benchmark in the efficient management of public lighting.
Desde sus inicios, Letter Ingenieros apostó en su plan estratégico por la gestión energética municipal. En años anteriores, sus socios habían desarrollado gran parte de los planes de optimización energética municipal de Andalucía y era por tanto, un tema que dominaban.
Aprovechando que hemos sido adjudicatarios de un contrato de esta temática aplicada al alumbrado público, en las próximas dos entregas hablaremos de gestión energética municipal. En este primer post nos centraremos en definir la gestión energética aplicada al alumbrado de Ayuntamientos, cómo se regula, y algunas pinceladas del coste que les supone y cómo lo realizan a día de hoy.
El alumbrado público
El alumbrado público es uno de los servicios municipales que deben ser prestados de manera obligatoria por parte de los municipios y supone un coste económico y ambiental muy alto para las entidades locales. El artículo 26.2 de la LBRL establece expresamente que las Diputaciones tiene competencia para: “Coordinar los servicios de alumbrado público en los municipios de menos de 20.000 habitantes”. Al ayuntamiento le corresponde el mantenimiento y conservación de las instalaciones de alumbrado público, así como el abono de los costes por consumo de energía eléctrica ocasionados.
Derecho de los ciudadanos
Además, se trata de un servicio público obligatorio destinado a los usuarios de los espacios públicos que permite la visión nocturna mediante la iluminación artificial. Tiene la finalidad de facilitar la actividad de la ciudadanía, dándole seguridad y confort a través de la implantación, mantenimiento, control y gestión de las instalaciones necesarias.
El servicio de gestión y explotación de las instalaciones de alumbrado público es una de las competencias básicas de los ayuntamientos, sin embargo, supone a la vez un gran reto: optimizar los gastos en la explotación del servicio mejorando las instalaciones, para alcanzar unos niveles de eficiencia y eficacia que reviertan en un buen servicio a la ciudadanía.
Coste y gestión del servicio de alumbrado público
La próxima semana pondremos números, según el informe del Tribunal de Cuentas, pero ya os adelantamos que el coste medio del servicio de alumbrado público en los municipios españoles, según tramos de población, fue el siguiente:
En la próxima entrega analizaremos estos datos, pero como vemos en los municipios más pequeños el coste es sensiblemente superior.
En el mismo informe vemos que la gestión directa fue la forma utilizada, en concreto, por el 82% de los ayuntamientos. También analizaremos el estado de penetración de ESES (Empresas de Servicios Energéticos).
Esperamos te hayan resultado de interés los datos mostrados. La próxima semana nos vemos analizando estos y muchos datos más en torno al alumbrado publico municipal.
