“…The projects have also demonstrated clear synergies between applied and scientific research. While the projects were driven by a very concrete and applied objective related to fostering wind energy development, it has produced a public database that is already being used in academic pursuits (Rondanelli et al 2015;Watts et al 2016). The scientific use of these observational and modeling results has led to the documentation of strong drainage winds along valleys traversing the Atacama Desert Jacques-Coper et al 2015), while the interesting wind regime in the Taltal region may deserve a more detailed study in the near future as well.…”

A Chilean program explores winds over the Atacama Desert region and is producing a public model and observational database in support of the development of wind energy projects. WIND ENERGY EXPLORATION OVER THE ATACAMA DESERTA Numerical Model-Guided Observational Program ricardo c. Muñoz, Mark J. Falvey, Mario arancibia, valentina i. astudillo, Javier elgueta, Marcelo ibarra, christian santana, and caMila vásquez R enewable energy, especially wind and solar, is an increasingly important field in applied meteorology and climate science. From the initial studies that explore the availability of these energy resources in a given area, to the forecasting models required to optimize the operation of wind or solar power plants, meteorological expertise is needed to design and execute measurement programs, and for the modeling of resource variability. Renewable energy poses special challenges compared to more traditional meteorological applications (Emeis 2013). In the case of wind power, for example, most phenomena of interest occur within the atmospheric boundary layer over horizontal scales ranging from the microscale to the mesoscale. Moreover, the viability of many renewable energy projects depends on the accuracy of the meteorological variables measured and modeled, with even small errors having large financial implications. On the other hand, the emergence of the renewable energy industry has led to a significant increase in the number of measuring sites being deployed worldwide, often in locations previously devoid of meteorological data. The commercial market for meteorological instrumentation has also responded, with the development of sensors tailored to satisfy specific renewable energy requirements. While this enhanced data availability and new instrumentation certainly has great scientific potential, it is true that because of the commercial interests behind most renewable energy projects, the associated meteorological information is usually not fully available to the general scientific 2079OCTOBER 2018 AMERICAN METEOROLOGICAL SOCIETY |

“…Indeed, already at the end of 2016, Chile became the top PV installer in Latin America, ranking 10 th globally for newly added capacity during 2016 [Hasan et al, 2017]. Additionally, geographical characteristics such as long coastlines, valleys and mountains, create significant wind potential which is estimated at approximately 40,000 MW (Watts et al, 2016 In terms of PV-specific assumptions, we modelled the technology shares of the current PV installed capacity in Chile on the basis of the latest respective figures for the whole world (Fraunhofer ISE, 2018), i.e., 70% multi-crystalline (mc-) Si, 24% single-crystalline (sc-Si) and 6% cadmium telluride (CdTe). In our future scenarios for 2035, these shares are then expected to change to 50% mc-Si, 20% sc-Si and 30% CdTe.…”

Chile is one of the fastest-growing economies in Latin America, with a mainly fossil fuelled electricity demand and a population projected to surpass 20 million by 2035. Chile is undergoing a transition to renewable energies due to ambitious national targets, namely to generate 60% of its electricity from local renewable energy by 2035, and to achieve a 45%renewable energy share for all new electric installed capacity. In this work, we present a comprehensive energy analysis of the electricity generation technologies currently deployed in Chile. Then, we analyse potential future scenarios, considering a large deployment of RE, mainly PV and wind, to replace coal-fired electricity. The life cycle assessment (LCA) and net energy analysis (NEA) methods are applied in parallel to provide complementary indicators, respectively nr-CED and EROI, and identify weak spots and future opportunities. Special focus is given to the effect on EROI of transporting fossil fuels to Chile. Results show that a large deployment of PV and wind can significantly improve the overall net energy performance of electricity generation in Chile, while leading to an electricity supply mix that is >60% less reliant on non-renewable energy.

“…Some authors have stated that the best future wind projects in Chile could achieve an average capacity factor of 37.9%. In the worst scenario, it would reach a factor of 25.2% (Watts et al, 2016), a good prospect for wind generation. Watts and Jara (2010) have suggested that a viable option to reduce carbon emissions in the northern area of Chile is to encourage wind power generation.…”

Effect of Climate Change on wind speed and its impact on optimal power system expansion planning: The case of Chile

2019

This work assesses the changes in power capacity expansion decisions regarding power generation and transmission that occur when the effects of Climate Change on wind speed are captured in the decision model. Considering an 85-year period (2016-2101), we use a Mixed-Integer Linear Program (MILP) model to analyze the optimal power capacity expansion in diverse types of power generation technologies, throughout the years and geographical locations. The optimization model minimizes the total (investment and operational) costs of the power system subject to several technical and economic constraints. We implement our model using the main Chilean power system. We compare two scenarios: one assuming that Climate Change affects wind speeds and hence wind farm capacity factors and the other assuming it does not. Our results reveal that, when taking into account the impact of Climate Change on wind speed, the optimal power generation and transmission expansion plan is different than when ignoring this effect. The variation of wind speed affects not only wind power capacity installed, but also other-technology power capacity installed. In particular, power capacity installed in wind and solar generation plants is higher (measured in MW installed) than the power capacity installed when we ignore the effects of Climate Change; and power capacity installed in diesel and natural gas technologies are lower. We perform sensitivity analyses, changing power capacity expansion limits and the discount rate, to check for the robustness of our results.
