Based on the information collected, an analysis is made from the obligations set forth in the contract and recommendations are made to the grantor (Ministry of Energy) and concessionaire (Sopesa SAESP) which are reflected in the monthly Audit Report, in order to to improve the provision of electric power service in the Department.
The National Development Plan 2014-2018 determined in its axis “A- A Prosperous, Equitable Caribbean without Extreme Poverty”, as a priority for the Archipelago, the need to develop projects, policies and initiatives aimed at reducing the consumption of DIESEL fuel as a primary source in its Objective 4:“ Advancing towards the provision of energy cleaner and less expensive ”.
In coherence with this, the Departmental Development Plan has established in its strategic axis the development of a Sustainable Archipelago, based on the development of projects that allow the current use of DIESEL to be displaced by energies from renewable sources.
Following these premises, and based on CONPES 3855 document, the route is established so that within the framework of the Clean Investment Funds (CIF – Clean Investment Funds), resources are received from the Clean Technology Fund (CTF – Clean Technology Fund ). Resources that were destined to finance and scale projects in the areas of urban transport, energy efficiency (EE) and renewable energies (FNCER). Starting with a pilot for 14 users on Santa Catalina Island and 1 institutional user on San Andrés Island.
The objective of this pilot was to implement and evaluate solutions based on Energy Efficiency and Renewables, in order to establish the basis for the development of the massive Efficiency Plan with allocated resources of USD $ 10 million.
In 2017, in alliance with the Government of the Department, EEDAS developed the socialization and sensitization of the community of the archipelago of San Andrés, Providencia and Santa Catalina regarding the energy transformation aiming towards the efficient use of renewable energies and unconventional sources of energy in the Seaflower Biosphere Reserve
The number of socializations carried out was 16,000 throughout the Archipelago, door-to-door visits were made in each of the selected homes, explaining the energy transformation and communicating the benefits acquired after the efficient use of energy resources, in order that users learned and internalized a series of behavioral guidelines on the use of energy.
EEDAS identified nine (09) energy efficiency recommendations prioritized towards high consumption elements and focused on the customs of the region (culture, idiosyncrasy, physical characteristics) information that was included within the advertising material delivered to users by EEDAS S.A. E.S.P. Through brochures and posters on energy efficiency and Non-Conventional Sources of Renewable Energy and the format of socialization surveys for the residential and non-residential sector.
In the Archipelago, 120,000 barrels of oil are consume annually in the transportation component, a situation that exceeds consumption for electricity production by 25%. This situation within the biosphere reserve calls for the establishment of specific plans for the revision and transformation of the high dependence on fossil fuel.
Due to the strengths of the new EEDAS headquarters and its Insular Monitoring Center, it is important to carry out a test pilot for electric vehicles to determine the following parameters:
Durability of the components.
Stability and duration of the accumulators.
Renewable charging systems.
Performance and performance.
As EEDAS carries out Auditing and monitoring tasks for energy and renewable transformation projects, it becomes the ideal vehicle for testing 2 electric transport systems.
The vehicles will be charge through a system of photovoltaic panels interconnected with the photovoltaic solar power system of the new Headquarters (Grid Tie).
The system to be use in an area of 60m2 will contain the following elements:
a.- Structure.
b.- Photovoltaic panels.
c.- Investors / Regulators / Control.
d.- Measurement and monitoring system.
As a complement to the new EEDAS S.A. Headquarters projects, this project was structure for the application of a hybrid system (photovoltaic – wind) for self-generation of energy in the new educational classrooms and the administrative building of the Caribbean headquarters of the National University (San Luis Headquarters). Besides, it allows achieving the development of energy efficiency alternatives that contribute to the reduction of subsidies for lower rates; this project owned by EEDAS S.A. E.S.P., is oriented to active buildings and with the purpose that the model remunerates its operating and investment costs via kWh produced.
The project has been operating since 2014, where the system tests and necessary adjustments were carry out to connect to the network. Currently, the system installed at the National University represents the first Grid Tie system in the region and has provided valuable information that EEDAS has incorporated into its project bank, especially the energy transformation process of the Archipelago and the New Headquarters.
Additionally, EEDAS carried out two photovoltaic installations. The first one was for the First Baptist School on the Hill that aimed to cover about a quarter of its energy needs (8 kWp). The other was for the first Baptist Church, which in the first phase generated about 40% of its consumption (3 kWp) and in the second phase, with accumulators (batteries) that target 90% of the demand, taking advantage of the fact that the islands have an excellent wind and solar resource.
EEDAS S.A. E.S.P. in 2016 presented to the Mayor of the Municipality of Providence and Santa Catalina a conceptual proposal for the development of a floating solar auto-generation project in the Agua Dulce dam (Fresh Water Dam). This project has a primary energy destination for the treatment plant of pumping of the aqueduct or in its defect of the Public Lighting of the sector.
This proposal, based on the advantage of installing panels in stable bodies of water (dams, lakes, etc.) where direct and indirect radiation (known as albedo) is use, given the reflection characteristics of the water, increasing solar use. In addition, the bodies of water maintain lower temperatures, which increases the efficiency and performance of the panels.
The project was known by the Global Green Growth Institute GGGI firm, which seeks to implement the project with international cooperation resources, requiring the development of previous studies aimed at the implementation of a floating solar self-generation installation in the Fresh Water dam. Decision was made to hire EEDAS SA E.S.P., based on her experience in renewable energies as up to $ 22 thousand USD worth.
The energy of the system will be used to supply part of the energy consumption of the pumping station of the Providence and Santa Catalina, which has an average monthly consumption of 8,000 kWh.
During 2019, an important achievement was accomplish by completing, after five years of work, the approval of the project “Research for the strengthening of capacities in the provision of energy in the islands”. The cost worth $ 6,996 million (resources CTeI SGR OCAD), was obtained in the Ministry of Science, highlighting that the evaluation committee recommended EEDAS S.A. for its experience and knowledge as executor.
This project is a turning point for energy in the islands because it incorporates the PIMMA Monitoring, Measurement and Analysis Platform as a center, which will collect all the information on the islands’ energy system and generate databases for 5 power lines. This Research is associated with the same number of scholarships for master degrees; training for more than 1,000 inhabitants and the implementation of 2 pilot projects. The first self-generation solar medium-scale installation with 140 kWp capacity and a pilot of green electroline stations and electric vehicles (6) to evaluate the incorporation of a mass and particular electrical transport system to the clean energy matrix of the Islands.
This project is of great relevance for the Islands, since it aims to establish the foundations for a future energy transformation, not only generating experience, but also defining knowledge as a critical mass for the future development of projects, with an approach aimed at building capacities in the population.
The relevant figure: The pilots associated with the project, by 2040 will reduce 3,220 Tons of CO2 in emissions (by replacing DIESEL with photovoltaic solar energy and mini-wind systems).
The fishing terminal for artisanal fishermen in the northern area of San Andrés, has the implementation of a solar / mini-wind self-generation system with a capacity of 50 kWp and the development of Energy Efficiency measures that allow reducing the projected consumption of the building by 50%, with estimated savings per month for the department of $ 12 million and for the nation of $ 14 million in subsidies, with a total investment of $ 900 million.
The San Andrés fishing terminal is located in the industrial zone of the department, adjacent to the facilities where the DIMAR operates, a place that will become the main site for the collection of marine product, processing and sale, with which the strengthening of artisanal fishing activity and generate a whole social economy around fishing on the Island of San Andrés.
At a general level in the fishing industry, the energy cost associated with the cold chain is one of the components with the greatest weight in operating costs. The islands are not alien to this situation and from the future perspective, the cost generated in the energy bill will be one of the main challenges to face when starting the fishery, because the freezing systems start from an important consumption base (empty), which increases with demand and this combined with a significant cost per kilowatt hour will have to be validated to guarantee the sustainability of the operation.
The scope of this project is the activities of information analysis, data collection, design, preparation and implementation of energy efficiency measures with emphasis on the use of Non-Conventional Renewable Energy Sources as a cost reduction measure in operation and reduction use of fossil fuels as a primary energy source and therefore GHG Greenhouse Gas emissions.
The relevant figure: By 2040 the project will reduce 1,073 Tons of CO2 in emissions (by replacing DIESEL with photovoltaic solar energy and mini-wind systems).
The main purpose of the new EEDAS Bio Climatic Headquarters is to meet the need to strengthen the operational structure and develop efficient cost management, contributing to the management of the energy transformation process of the Islands, as the new headquarters is an operational management laboratory comprehensive energy and rational use of energy.
EEDAS Headquarters operates in facilities located in the renowned Punta Hansa sector. At present, the automation systems and the self-generation system are operational.
The building has generated a total change in the operational dynamics of the organization, guaranteeing comfort and safety to the workers, highlighting the strategic importance of having the only building with Bio Climatic characteristics in the Archipelago, which places EEDAS as a leader in these Projects.
Among the highlights of the project are:
25 kW Photo Voltaic Self Generation System
EEDAS has 3 years in advance of Law 1715 of 2014, during which she formulated, structured and executed 2 projects with Non-Conventional Renewable Energy Sources. The main strength of the New Headquarters corresponds to the fact that 85% of its consumption comes from clean energy, which also generates cost savings for the service.
LIGHTING AUTOMATION SYSTEM.
EEDAS building has a fully automated centralized lighting system, with high-efficiency T5 and LED luminaires, comparable to modern systems such as the one used at the Nuevo El Dorado Airport.
In the Energy Efficiency component, the UPME identified as one of the critical factors in energy efficiency in the Islands, the lighting of both homes and commercial and official buildings. In this sense, EEDAS observes the business potential associated with energy efficiency, which is why she designed and developed an automated system for energy saving and as a “Show Room” for potential clients.
HVAC AUTOMATION SYSTEM.
One of the most innovative aspects of the EEDAS Building is the Air Conditioning automation system, which at a cost 70% less than a centralized system, takes advantage of the Air Inverters available in the market to manage consumption.
TECHNICAL ANALYSIS FOR EACH UNIT
The system used by EEDAS takes advantage of the lighting automation system (sensors, KNX system) to control the Air Conditioning units with RF signal inductors, activating or deactivating functions according to the movement of personnel (sensors).
The objective of the system is to achieve the maximum efficiency of the component responsible for 70% of consumption in institutional buildings and that represents close to $ 60,000 million in subsidies per year at the Department level.
From the financial point of view, the project for the new headquarters represents real and effective savings, since the headquarters has, as said at the beginning, a self-generation system of energy from a solar system located on its roof with a capacity of 25 kW.
The objective is to solve the public lighting deficit in the southern area of San Andrés Island, for which an energetically sustainable solution was developed for public lighting because there are no electrical networks and it is a traffic area for both residents and tourists who have security problems. The project is of great importance to establish a change in the public lighting system of the Islands, which is responsible for generating about 2,600 tons of CO2 per year.
The project consists of the installation of 180 LED luminaires with photovoltaic power systems that include their own storage system (batteries). The luminaires are distributed in the South End sector, which does not have a public lighting supply or infrastructure available for a potential expansion of conventional lighting.
The solution represents a challenge, depending on the investment and the application of alternatives based only on energy efficiency, compared to the necessary investment and sustainability in the medium and long term. Despite the fact that there are initiatives in other countries and in large cities with this type of technology, in non-interconnected areas (ZNI) and in island areas, no innovation has been applied in public lighting systems beyond the replacement of the luminaires to LED.
Project location.
This project goes from the eastern margin of the Island to the Elsy Bar sector. The first support located at the coordinates N 12º 29 ’32’ ‘and W 81º 43′ 18 ”, crossing the bypass towards the south passing through south end (South End), bordering towards the West intermittently towards the north until the West View sector, with the last support located at the coordinates N 12º 30 ’80’ ‘and W 81º 43’ 46 ” . Additionally, secondary roads such as Velodia Road and Elsy Bar, where there was no infrastructure, will be covered within the project.
The relevant figure: By 2040 the project will reduce 545 Tons of CO2 in emissions (by replacing DIESEL with photovoltaic solar energy).
EEDAS S.A. E.S.P. en el año 2016 presentó a la alcaldía del Municipio de Providencia y Santa Catalina una propuesta conceptual para el desarrollo de un proyecto de auto generación solar flotante en la represa de Agua Dulce (Fresh Water Dam), con destino energético primario para la planta de tratamiento de bombeo del acueducto o en su defecto del Alumbrado Público del sector.
Dicha propuesta se basa en la ventaja de instalar paneles en cuerpos de agua estables (represas, lagos, etc.) donde se aprovecha la radiación directa e indirecta (conocida como albedo) dadas las características de reflexión del agua, aumentando el aprovechamiento solar. En adición, los cuerpos de agua mantienen temperaturas menores, lo que aumenta la eficiencia y desempeño de los paneles.
El proyecto fue conocido por la firma Global Green Growth Institute GGGI, quien busca implementar el proyecto con recursos de cooperación internacional, requiriendo el desarrollo de estudios previos con destino a la implementación de una instalación flotante de auto generación solar en la represa de Fresh Water, contratando a EEDAS S.A. E.S.P. con base en su experiencia en energías renovables por valor de $USD 22 mil.
La energía del sistema se destinará a suplir parte del consumo energético de la estación de bombeo del acueducto de Providencia y Santa Catalina la cual tiene un consumo mes promedio de 8.000 kWh.
La cifra relevante: Si se implementa un plan de transformación, al 2040 se podrían reducir 1.805 Toneladas de CO2 en emisiones (al reemplazar DIESEL por energía solar fotovoltaica flotante).
En el año 2017 en alianza con la Gobernación del Departamento, EEDAS desarrolló la socialización y sensibilización a la comunidad del archipiélago de San Andrés, Providencia y Santa Catalina en cuanto a la transformación energética apuntando hacia el uso eficiente de energías renovables y fuentes no convencionales de energía en la reserva de biosfera Seaflower.
El número de socializaciones realizadas fue de 16.000 en todo el Archipiélago, se efectuaron visitas puerta a puerta en cada una de las viviendas seleccionadas, explicando la transformación energética y comunicando los beneficios adquiridos tras la utilización eficiente de los recursos energéticos, con el fin de que los usuarios aprendieran e interiorizaran una serie de pautas de comportamiento sobre el uso de la energía.
EEDAS identificó nueve (09) recomendaciones de eficiencia energética priorizadas hacia los elementos de alto consumo y enfocados a las costumbres de la región (cultura, idiosincrasia, características físicas) información que fue incluida dentro del material publicitario entregado a los usuarios por parte de EEDAS S.A. E.S.P. a través de folletos y afiches de eficiencia energética y Fuentes No Convencionales de Energía Renovables y formato de encuestas de socialización para el sector residencial y no residencial.
El Plan Nacional de Desarrollo 2014-2018 determinó en su eje “A. Caribe próspero, equitativo y sin pobreza extrema”, como prioridad para el Departamento Archipiélago, la necesidad de desarrollar proyectos, políticas e iniciativas orientadas a reducir el consumo de combustible DIESEL como fuente primaria en su Objetivo 4: “Avanzar hacia la provisión de una energía más limpia y menos costosa”.
En coherencia con este, el Plan Departamental de Desarrollo, tiene establecido en su eje estratégico el desarrollo de un Archipiélago Sostenible, basado en el desarrollo de proyectos que permitan desplazar el actual uso del DIESEL por energías provenientes de fuentes Renovables.
Atendiendo dichas premisas, y con fundamento en el documento CONPES 3855, se establece la ruta para que en el marco de los Fondos de Inversión Limpia (CIF – Clean Investment Funds), se reciban recursos del Fondo de Tecnologías Limpias (CTF – Clean Technology Found). Recursos que fueron destinados a financiar y escalar proyectos en las áreas de transporte urbano, eficiencia energética (EE) y energías renovables (FNCER). Iniciando con un piloto destinado a 14 usuarios en la Isla de Santa Catalina y 1 usuario institucional en la Isla de San Andrés.
Éste piloto tuvo como objetivo implementar y evaluar soluciones basadas en Eficiencia Energética y Renovables, de manera que se establezca la base para el desarrollo del Plan de Eficiencia masivo con recursos asignados de USD$10 millones.
Como complemento al proyecto nueva Sede EEDAS S.A. E.S.P., se estructuró el proyecto para la aplicación de un sistema hibrido (fotovoltaico – eólico) para auto generación de energía en las nuevas aulas educativas y el edificio administrativo de la sede Caribe de la Universidad Nacional (Sede San Luis), de tal manera que permite lograr el desarrollo de alternativas de eficiencia energética que contribuyen con la disminución de subsidios por menores tarifas; éste proyecto de propiedad de EEDAS S.A. E.S.P., está orientado a edificaciones activas y con la finalidad que el modelo remunere sus costos operativos y de inversión vía kWh producido.
El proyecto se encuentra operando desde el año 2014, donde se realizaron las pruebas del sistema y ajustes necesarios para acoplarse a la red. En la actualidad, el sistema instalado en la Universidad Nacional representa el primer sistema Grid Tie en la región y ha suministrado información valiosa que EEDAS ha incorporado a su banco de proyectos, en especial al proceso de transformación energética del Archipiélago y la Nueva Sede. Adicionalmente, EEDAS realizó dos instalaciones fotovoltaicas: una para el colegio Bautista de la Loma que apuntó a cubrir cerca de una cuarta parte de sus necesidades energéticas (8 kWp) y la otra para la primera iglesia Bautista de la Loma, que en la primera fase generó cerca del 40% de su consumo (3 kWp) y en la segunda fase, con acumuladores (baterías) que apuntan al 90% de la demanda aprovechando que las islas cuentan con un excelente recurso eólico y solar.
Durante la vigencia 2019 se alcanzó un logro importante al completar tras cinco años de trabajo la aprobación del proyecto “Investigación para el fortalecimiento de las capacidades en la prestación de energía en las islas”, por valor de $6.996 millones (recursos CTeI SGR OCAD), aprobación obtenida en el MinCiencias y destacando que el comité evaluador recomendó por su experiencia y conocimiento a EEDAS S.A. E.S.P. como ejecutor.
Este proyecto es un punto de inflexión para la energía en las islas debido a que, incorpora como centro la Plataforma de Monitoreo, Medición y Análisis PIMMA, que recopilará toda la información del sistema energético de las islas y generará bases de datos para 5 líneas de investigación asociadas a igual número de becas para maestría, capacitación para más de 1.000 habitantes y la implementación de 2 pilotos: La primera instalación a mediana escala solar de auto generación con 140 kWp de capacidad y un piloto de electrolineras verdes y vehículos eléctricos (6) para evaluar la incorporación de un sistema de transporte masivo y particular eléctrico a la matriz energética limpia de las Islas.
Este proyecto es de gran relevancia para las Islas, dado que apunta a establecer los cimientos para una futura transformación energética, no solo generando experiencia, sino definiendo el conocimiento como masa crítica para el desarrollo futuro de proyectos, con un enfoque dirigido a formar capacidades en la población.
La cifra relevante: Los pilotos asociados al proyecto, al 2040 reducirán 3.220 Toneladas de CO2 en emisiones (al reemplazar DIESEL por energía solar fotovoltaica y sistemas mini eólicos).
En el Archipiélago se consumen anualmente 120.000 barriles de petróleo, en el componente de transporte, situación que supera el consumo para producción de energía eléctrica en un 25%. Esta situación dentro de la reserva de biósfera llama a establecer planes específicos para la revisión y transformación de la alta dependencia de combustible fósil.
Teniendo en cuenta las fortalezas de la nueva sede EEDAS y su Centro Insular de Monitoreo, es importante realizar un piloto de pruebas a vehículos eléctricos que permitan determinar los siguientes parámetros:
Durabilidad de los componentes.
Estabilidad y duración de los acumuladores.
Sistemas de carga a partir de renovables.
Rendimiento y desempeño.
En atención a que EEDAS desarrolla labores de Interventoría y de seguimiento a los proyectos de transformación energética y renovable, se convierte en el vehículo ideal para la prueba de 2 sistemas de transporte eléctricos.
La carga de los vehículos se hará a través de un sistema de páneles fotovoltaicos interconectados con el sistema de alimentación solar fotovoltaica de la nueva Sede (Grid Tie).
El sistema a utilizar en un área de 60m2, contendrá los siguientes elementos:
a.- Estructura.
b.- Paneles Fotovoltaicos.
c.- Inversores / Reguladores / Control.
d.- Sistema de medida y monitoreo.
El objetivo del proyecto es monitorear el desempeño de los vehículos en comparación con la camioneta Ford Ranger DIESEL, actualmente en uso en EEDAS.
El terminal pesquero para los pescadores artesanales de la zona norte de San Andrés, cuenta con la implementación de un sistema de auto generación solar / mini eólico con capacidad de 50 kWp y el desarrollo de medidas de Eficiencia Energética que permitan reducir el consumo proyectado de la edificación en un 50%, con ahorros estimados mes para el departamento de $12 millones y para la nación de $14 millones en subsidios, con una inversión total de $900 millones.
El terminal pesquero de San Andrés se encuentra ubicado en la zona industrial del departamento, contiguo a las instalaciones donde funciona la DIMAR, lugar que se convertirá en el principal sitio de acopio de producto marino, procesamiento y venta, con lo cual se propende el fortalecimiento de la actividad pesquera artesanal y generar toda una economía social alrededor de la pesca en la Isla de San Andrés.
A nivel general en la industria de la pesca, el costo energético asociado a la cadena de frío es uno de los componentes de mayor peso en los costos operacionales. Las islas no son ajenas a esta situación y desde la perspectiva futura, el costo generado en la factura de energía, será uno de los principales retos a enfrentar en el momento de poner en funcionamiento la pesquera, debido a que los sistemas de congelación parten de una base de consumo importante (vacío), la cual se incrementa con la demanda y esto combinado con un costo importante por kilovatio hora tendrá que ser validado para garantizar la sostenibilidad de la operación.
Este proyecto tiene como alcance las actividades de análisis de información, levantamiento de datos, diseño, preparación e implementación de medidas de eficiencia energética con énfasis en el uso de las Fuentes No Convencionales Energías Renovables como medida de reducción de costos en la operación y de reducción de uso de los combustibles fósiles como fuente energética primaria y por ende las emisiones de Gases Efecto Invernadero GEI.
La cifra relevante: Al 2040 el proyecto reducirá 1.073 Toneladas de CO2 en emisiones (al reemplazar DIESEL por energía solar fotovoltaica y sistemas mini eólicos).
La nueva Sede Bio Climática EEDAS, tiene como objeto principal atender la necesidad de fortalecer la estructura operativa y desarrollar una gestión eficiente en costos, aportando en la gestión del proceso de transformación energética de las Islas, al ser la nueva sede un laboratorio operacional de gestión integral energética y uso racional de energía.
La Sede de EEDAS opera en las instalaciones ubicadas en el reconocido sector de Punta Hansa. En la actualidad se encuentran operativos los sistemas de automatización y el sistema de auto generación.
La edificación ha generado un cambio total en la dinámica operacional de la organización, garantizando comodidad y seguridad a los trabajadores, destacando la importancia estratégica de contar con la única edificación con características Bio Climáticas en el Archipiélago, el cual ubica a EEDAS como líder en estos proyectos.
Entre los aspectos más destacados del proyecto se encuentran:
Sistema de Auto Generación Foto Voltaica de 25 kW
EEDAS cuenta con 3 años de anticipación a la Ley 1715 de 2014, durante los cuales formuló, estructuró y ha ejecutado 2 proyectos con Fuentes No Convencionales de Energía Renovable. La principal fortaleza de la Nueva Sede corresponde a que el 85% de su consumo proviene de energía limpia, lo cual no solo genera el ahorro del costo por el servicio.
Sistema de Automatización de Iluminación.
El edificio EEDAS cuenta con un sistema centralizado de iluminación completamente automatizada, con luminarias de alta eficiencia T5 y LED, comparables con sistemas modernos como el utilizado en el aeropuerto Nuevo el Dorado.
En el componente de Eficiencia Energética la UPME identificó como uno de los factores críticos en eficiencia energética en las Islas, la iluminación tanto de viviendas como de edificaciones comerciales y oficiales. En este sentido EEDAS observa el potencial de negocio asociado a eficiencia energética por lo que diseñó y desarrolló un sistema automatizado para ahorro energético y como “Show Room” ante potenciales clientes.
Sistema de Auto Generación Foto Voltaica de 25 kW
El sistema se opera desde una central automatizada en el Centro Insular de Monitoreo, que activa y controla los sensores ubicados a lo largo del edificio. El sistema permite controlar los tiempos, intensidades, sensibilidad y gestión del sistema. Adicionalmente la información se enlaza con una plataforma de seguimiento para vigilar y monitorear el desempeño.
Sistema de Automatización de Climatización.
Uno de los aspectos de mayor innovación del Edificio EEDAS es el sistema de automatización de Aire Acondicionado, el cual con un costo 70% menos que un sistema centralizado, aprovecha los Aires Inverter disponibles en el mercado para gestionar el consumo.
Análisis técnico por cada unidad
El sistema utilizado por EEDAS aprovecha el sistema de automatización de iluminación (sensores, sistema KNX) para controlar con unos inductores de señal RF las unidades de Aire Acondicionado, activando o desactivando funciones conforme el movimiento del personal (sensores).
El objetivo del sistema es lograr la máxima eficiencia del componente responsable del 70% del consumo en edificaciones institucionales y que representa cerca de $60.000 millones en subsidios al año a nivel del Departamento.
Desde lo financiero, el proyecto de la nueva sede representa un ahorro real y efectivo, ya que la sede cuenta como se dijo al inicio, con un sistema de autogeneración de energía a partir de un sistema solar ubicado en su cubierta con capacidad de 25 kW .
El objetivo es solucionar el déficit de alumbrado público en la zona sur de la Isla de San Andrés, para lo cual se desarrolló una solución sostenible energéticamente para la iluminación pública debido a que no existen redes eléctricas y es una zona de tráfico tanto de residentes y turistas que presenta problemas de seguridad.
El proyecto es de gran importancia para establecer un cambio en el sistema de alumbrado público de las Islas, el cual es responsable de generar cerca de 2.600 toneladas de CO2 año.
El proyecto consiste en la instalación de 180 luminarias LED con sistemas de alimentación fotovoltaica las cuales incluyen su propio sistema de almacenamiento (baterías). Las luminarias están distribuidas en el sector de South End, el cual no cuenta con suministro de alumbrado público ni infraestructura disponible para una potencial expansión de iluminación convencional.
La solución representa un reto, en función de la inversión y la aplicación de alternativas basadas solo en eficiencia energética, frente a la inversión necesaria y la sostenibilidad en el mediano y largo plazo. A pesar de que existen iniciativas en otros países y en las grandes ciudades con este tipo de tecnología, en las zonas no interconectadas (ZNI) y en las zonas insulares, no se ha aplicado innovación en los sistemas de alumbrado público más allá del reemplazo de las luminarias a LED.
Ubicación del Proyecto.
El proyecto se extiende desde la margen oriental de la Isla a la altura del sector de Elsy Bar, con el primer apoyo localizado en las coordenadas N 12º 29’ 32’’ y W 81º 43’ 18’’, recorriendo la vía circunvalar hacia el sur pasando por punta sur (South End), bordeando hacia el Occidente de manera intermitente hacia el norte hasta el sector de West View, con el último apoyo localizado en las coordenadas N 12º 30’ 80’’ y W 81º 43’ 46’’. Adicionalmente se cubrirán dentro del proyecto vías secundarias como Velodia Road y Elsy Bar, donde no existía infraestructura.
La cifra relevante: Al 2040 el proyecto reducirá 545 Toneladas de CO2 en emisiones (al reemplazar DIESEL por energía solar fotovoltaica).
