The main activities of the project are:
- Implementation of an electric microgrid powered by a hybrid renewable energy system capable of harnessing indigenous resources (biomass, wind and sun) and meeting the energy demand of the population.
- Awareness and training of the people who will be linked to the project in the operation, maintenance and use of the hybrid plant.
- Ensuring the replicability and sustainability of the system in its social, economic, environmental and geographical aspects.
Hybridization of renewable systems, composed of two or more energy generation systems, is a solution with great potential in multiple places in Cuba. Among them, areas isolated from conventional electricity supply, with specific needs for both electricity and heat and with resources that can ensure its manageability and satisfy the demand of the populations affected. Appropriation of the technology by the population has been addressed throughout the project through two strategies.
The first one consists on adapting the proposed technology (the biomass gasification and wind - photovoltaic hybrid system) to local conditions, considering both the resources and the needs of the population under these conditions. This adaptation also starts with an in-depth analysis of the previous experiences.
The second strategy to achieve the objective has been the creation of local capacity, using various agents involved (beneficiaries/users, operators, technicians, professionals in the energy sector…) in such a way that a process of technological appropriation is produced and to ensure sustainability over time and the ability to replicate the experience for other populations.
The second phase is on-going and will start up a demonstration facility in Matanzas province. The selected case study is an existing isolated grid presently supplied with a diesel genset in the municipality of Guasasa. The system will be redesigned to include a high percentage of energy generation coming from renewable energies in a sustainable microgrid concept.
TRAINING ITINERARY: "Fundamentals of electric microgrids with renewable energy sources for isolated communities"
Training is a fundamental action in HIBRI2. One of the fundamental objectives of this project is the technological appropriation of fully renewable and sustainable energy generation processes, the production of electricity from solar photovoltaic and wind energy and electric and thermal cogeneration through biomass gasification.
Capacity building is also essential to ensure the sustainability of the system over time and the ability to replicate the experience to other populations.
For this purpose, a three workshop training itinerary has been developed aimed at addressing the different project’s subject areas: hybrid generation plants with renewable energy (photovoltaic, wind, biomass), gasification, design and operation of electric microgrids, sustainability energy systems, energy efficiency and energy savings, geographic information systems and rural electrification of isolated communities, etc.
The training workshops are technical in nature, with theoretical and practical sessions, field visits and forums for discussion and exchange. Besides, the trainings seek to know the reality of current projects under development in line with the present work, at local and regional levels, thus promote the exchange of experiences between decision-makers and responsibles for energy planning and renewable energy deployment. Moreover, consolidate the existing relationships between the different groups interested in the subject within the region.
In addition to the specific work in each of the workshops, the student will develop a personal tutoring work that will be presented in the last workshop of the itinerary.
The three workshops will be recognized with a certification of achievement by CIEMAT and the UNESCO Chair in Environment and Development of the Higher Institute of Technologies and Applied Sciences, InSTEC.
- FIRST WORKSHOP: Technological state of renewable sources. Hybridization of systems for rural electrification. Biomass and wind energies. See program (PDF: 884kB)
- SECOND WORKSHOP: Design and implementation of hybrid systems. Measurement of the solar resource and photovoltaic technology. Geographic information systems.
- THIRD WORKSHOP: Sustainability and replicability of hybrid systems for rural electrification. Electric and thermal cogeneration from biomass gasification.
Workshop held within the framework of the predecessor project, phase 1, Hybridus: Cogeneration of electrical and thermal energy through a hybrid biomass-solar system for agricultural holdings on the island of Cuba.
Replicability and sustainability. System's socioeconomic, environmental and geographical aspects
Sustainability and replicability of the system
It consists, on the one hand, in carrying out a sustainability analysis on three fronts: environmental evaluation, socio-economic analysis (based on the costs of investment and operation and maintenance of the project and the Input-Output table of Cuba) and socio-impact assessment -institutional and, on the other, of a replicability study, based on geographic information systems, that takes into account the conditions of other similar sites detected (availability and characteristics of residual biomass, availability of the solar resource and population conditions).
Environmental Sustainability Analysis
The evaluation of environmental sustainability will be carried out through the Life Cycle Analysis (LCA) methodology. LCA is a methodology that evaluates the environmental impacts of a product or service during all stages of its life cycle from the extraction of all resources, through the stages of production, distribution and use and end of life (reuse, recycling, recovery and disposal). Based on technical data and emissions from the different activities that take place in the project life cycle and using databases, the environmental impact will be quantified. Finally, the stages and processes responsible for the greatest environmental burdens will be identified and reduction strategies will be evaluated.
Life cycle Analysis steps
Social and institutional impact Analysis.
A diagnosis of the institutional structure of the project and the impact of its development on the different relevant actors will be made. The proposed task aims to analyze the institutional structure of the project throughout the different phases that make up its life cycle. For this, the different actors involved in each phase will be identified as well as the relationship between them as a result of the implementation of the project. This analysis allows an institutional diagnosis as well as the identification of weaknesses and measures that could strengthen the institutional structure of the project studied.
Stages of the socio-institutional life cycle of the project
Socioeconomic impact Analysis for the Cuban economy
Based on a large-scale technology development scenario, which takes into account the country's resource and energy needs, the impact of such development in terms of job creation and economic stimulation will be analyzed. The input-output analysis is a tool based on the classic model developed by Leontief, which allows knowing in depth an economy by analyzing the interdependence between sectors through the description of the economic flows or transactions that take place in the production process.
Economic flows or transactions in a productive process
Based on data on investment and operation and maintenance costs throughout the different stages of the project life cycle and the Cuban Input-Output table, the impact on employment and the economy in Cuba would be estimated.
Taking into account a future scenario of large-scale penetration, the results will allow estimating the direct, indirect and induced impact on the generation of employment and increase in the production of goods and services in the different economic sectors of the Cuban economy.
Spatial and technological replicability
The development of this activity is carried out with geographic information systems, and takes into account the conditions of other similar sites (according with the results of HYBRIDUS project – Phase I). The study will be extended to other areas and will have the collaboration of the University of Las Tunas for its development. It will also take into consideration the technological characteristics of the micro network as determinants of its replicability.
