Assessment Of Adaptation Measures To Climate Change In The Paute River Watershed And Its Hydropower Plants
No full textClimate Change may impact ecosystem sensitive sectors such as hydropower generation, which is vital for energy supply in Latin America and in Ecuador. Since the Paute-Molino Hydropower Plant is Ecuador’s largest energy generation facility; strategies and measures for adapting to Climate Change in the Paute River Watershed and its hydropower plants are necessary. An assessment of adaptation options to Climate Change was performed. The results show that the top ten options are mainly related to Integrated Natural Resources Management (INRM), Improved Plant Operations and Ecosystems Conservation. These adaptation options can bring important benefits such as reducing current vulnerabilities, addressing likely climate impacts, delivering other non climate related benefits to the local population; and mitigating GHG emissions. The challenges for Hidropaute in order to adapt to Climate Change are: i) taking a proactive role and getting more involved in the implementation of coordinated programs for managing the entire watershed; ii) keeping Plant Factor (PF) at least the same than in past “normal” years during the dry season; while taking advantage of a likely stronger seasonality in order to promote more energy production during the wet season

Development Of A Waste Management Plan For A Drilling Waste In The Peruvian Jungle
No full textThe purpose of this project is to manage the drill cutting waste originated at the San Martin 1 location of Block 88, Camisea, Peru.
The drill cutting originated at the San Martin 1 location were treated with lime and piled in the area, which originates leachate and is a potential liability for the company. Nevertheless, the company wishes to find a better management solution for such a waste, as part of the company’s proactive environmental stance. This project was elaborated with the support of Pluspetrol Peru Corporation S.A., the operator of Block 88, Camisea. The company provided the author with access to the site company documentation, an open communication channel and basic criteria, which altogether simplified the tasks and allowed the author to follow a more elaborated methodology. Furthermore, the company welcomed the approach by the author.
This document is divided in 8 chapters, with the first two setting the framework for the project, the next three describing the waste and its potential liabilities, to then present a summary of the alternatives in chpater6, followed by the criteria for selection and selection on chapter 7 and the final conclusions and recommendations in chapter 8
Study Of Geothermal Energy In Ecuador And How It Can Be Harnessed For The Development Of The Electrical Sector
No full textEcuador is a country that depends mainly on hydro and fossil fuels for the generation of electricity; nevertheless, Ecuador has series problems on using both resources. The use of fossil fuels implies the imports of combustible which presents an important expenditure. Besides, thermoelectric units are near their life cycle, and their efficiency is low. On the other hand, the generation of electricity by hydro power plants decreases during the dry season between October and March. Consequently, it is necessary to look for another alternative that could be developed in a sustainable way. Because of Ecuador’s potential and the several technological, environmental and economical advantages, geothermal energy appears to be an important option for changing Ecuador’s energetic matrix. Technologically, geothermal energy has the highest capacity factor (0.85-0.95); environmentally, GHGs emissions and land use are negligible in comparison with fossil fuels and hydro, respectively; and economically, its capital cost per kW (4000kW) is minor than other renewable technologies. In this thesis project is analyzed the geothermic potential of the areas of Tufino-Chiles, Chalupas, and Chachimbiro. Furthermore, it is explained the environmental and social problems that may happen, and developed the costs of exploration and exploitation and the economic benefits that these projects would represent to the country. Finally, it is identified the main driving forces, barriers and stakeholders of this type of projects, and it is explained a strategy for developing geothermal power plants in the country
Harmonizing Energy Supply And Demand Through Energy Storage Mechanisms A Feasibility Study For The University Of Calgary
No full textToday’s energy thirsty society relies heavily upon the energy supply and infrastructure that has evolved over the course of many decades. During this time electricity has emerged as a favoured medium to deliver energy to a wide variety of uses. Energy in electric form is easily transportable and efficiently converted into other forms of energy such as mechanical, light, and heat energy. However, electric energy is by its very nature a perishable good. Once generated it must be consumed or else it goes to waste. Compounding this issue is society’s variable energy demand pattern which causes periods of peak and off-peak demand during the day and night respectively. These peaks force energy producers to have available capacity to satisfy the peak demand level even though it lasts for only a few hours each day. This inefficient system requires a generation capacity that is significantly higher than the average demand level. Together, the perishable nature of electricity and our variable consumption pattern, present a overwhelming challenge to energy providers and system operators. However, through the employment of energy storage mechanisms system operators can effectively store electricity produced in off-peak periods to be use in peak periods. This practice, sometimes referred to as time-shifting or demand-shifting, can have a measured impact in balancing the energy demand pattern to reduce peak consumption levels. At the same time, energy storage systems make better use of base-load electricity generation resources like nuclear and hydro-electric plants which must operate at a consistent rate. This paper examines the issues mentioned above in detail and explores the various energy storage mechanisms available as solutions. Each mechanism is discussed and evaluated based on its; storage efficiency, storage capacity, cost, environmental impact, and adaptability. Later, a case study is presented to explore the implementation of energy storage systems to improve energy use. The University of Calgary was selected as a hypothetical field trial for this case study, in which a battery storage system is proposed as the most suitable means of energy storage based on the metrics listed above in relation to the energy demands of the University. Finally, the results of the case study are extrapolated to ponder energy storage implementation on a larger scale
Determining The Viability Of Rice Huck Bioenergy In Ecuador
No full textEcuador‟s national electricity plan faces major challenges in the upcoming years: current oil derivative subsidies are economically unsustainable; and an increasing reliance on hydroelectric power can cause nationwide energy shortages, as shown 2009. It is for these reasons that this study proposes the use of decentralized forms of energy, like bioenergy, to help meet the country‟s future energy needs. Bioenergy is an attractive option because: (1) it monetizes various forms of waste (e.g. agro-waste); (2) its technology is tried and tested; (3) it reduces transition losses because energy output is used locally; and (4) it stimulates local economies. Because rice is one of Ecuador‟s largest agro-industries, its residue, rice husk, was selected as the bioenergy fuel in this analysis. Results indicate that the county of Daule- the highest rice producing region has the theoretical capacity to generate roughly 4MWe per annum; produce moderate financial returns; and provide more than 43 jobs to the region
Integrated Motor Vehicle Pollution Control Program To Reduce Exhaust Gas Emissions In Highland Cities : Quito
No full textFeasibility Study Of 10.2 Mw Wind Farm Project In Ecuador
No full textClean Development Mecanism (CDM) of the Kyoto Protocol has created a perception among renewable energy project developers that it is a new means of financing for both freshly new and on-going projects. Wind project development in Ecuador was experiencing a stalemate due to the country’s ailing economic problems after the 1999 Economic Crisis and subsequent dollarization and absence of investment capital. The CDM has been considered as a “stimulator” to bring one or two wind projects into operation until the sector secures the preferable investment conditions to attract investors without the help of the CDM. Considering the Ecuador’s Political, economical, technical, environmental, and social specificity, the Small-Scale CDM (SSc CDM), which has its own distinct rules in modalities and procedures spate from medium – to large-sized CDM projects, will be the form of CDM investment in the wind sector.
This Master’s project uses one wind project in Ecuador to assess its financial viability with and without the SSc CDM to illustrate whether the SSc CDM can improve financial performance of the project and the possible difficulties involved with using it.
Several recommendations are provided to make the Ecuadorian wind sector development feasible and the SSc CDM attractive
Landfill Bioreactors, A Step Towards Sustainability : Doña Juana Landfill Case Study
No full textThis report compares the landfill bioreactor and conventional landfill gas to energy projects at Dona Juana Landfill in Bogota, Colombia. The SWANA first order decay formula was used to model methane emissions. The landfill bioreactor produces more methane in a shorter period of time than the conventional landfill and therefore more energy over a 20 year time span. When hidden costs are included in the economic analysis, the landfill bioreactor is a good option for energy generation. Both projects are still expensive when compared to conventional energy generation in Colombia. In both cases, the foreseen impacts are not as significant as the current ones. It is necessary to realign the current management at the landfill in order to assure the success of the landfill bioreactor project. This realignment must be based on stakeholder interests, driving forces, and barriers. As evident from this case study, landfill bioreactors can contribute substantially to sustainable development
