“…Even more, 70% is reached in most of the scenarios without considering hydroelectric energy, as shown in Table 10. Despite being in accordance with results found by Munoz et al [5], this result is probably a slight overestimation of the total amount of non-dispatchable renewable generation achievable under these scenarios. The main source of possible overestimation of renewable generation integration in the current linear optimization model is the lack of a constraint to limit the minimum operational range of conventional generation such as coal and CCGT, which overestimates the capacity of these technologies to back changes in non-dispatchable renewable generation.…”

“…Therefore, with the aim of reaching the goal of 70% of electricity from renewables by 2050 [3,4], it is necessary to increase the operational flexibility of the grid, with energy storage being one of the most interesting alternatives. Munoz et al [5] showed that from a market perspective achieving 70% renewables was possible even without additional policies such as promotion of energy storage. However, there are some technical constraints that could hinder achieving this target and a more detailed analysis is required.…”

Long Term Impact of Grid Level Energy Storage on Renewable Energy Penetration and Emissions in the Chilean Electric System

Chile has abundant solar and wind resources and renewable generation is becoming competitive with fossil fuel generation. However, due to renewable resource variability their large-scale integration into the electricity grid is not trivial. This study evaluates the long-term impact of grid level energy storage, specifically Pumped Thermal Energy Storage (PTES), on the penetration of solar and wind energies and on CO2 emissions reduction in Chile. A cost based linear optimization model of the Chilean electricity system is developed and used to analyse and optimize different renewable generation, transmission and energy storage scenarios until 2050. For the base scenario of decommissioning ageing coal plants and no new coal and large hydro generation, the generation gap is filled by solar photovoltaic (PV), concentrated solar power (CSP) and flexible gas generation with the associated drop of 78% in the CO2 emission factor. The integration of on-grid 8h capacity storage increases the solar PV fraction which leads to a 6% reduction in operation and investment costs by 2050. However, this does not necessarily lead to further reductions in the long term emissions. Thus, it is crucial to consider all aspects of the energy system when planning the transition to a low carbon electricity system.

“…The main changes in the generation mix in the last decade are a large increase in the share of coal generation, a reduction in the share of hydropower (as a fraction of total generation), and an increase in the share of generation from biomass, wind, and solar. It is projected that more than 70% of the generation in 2050 will come from renewable energy resources (including large hydro), in line with the country's energy roadmap (Munoz et al, 2017a). As we mentioned in the introduction, in terms of market organization, generation, transmission, and distribution services are unbundled.…”

“…In [10], the authors evaluated the costs of reaching a 70% renewable energy target by 2050 in Chile, according to the goal announced by the government in 2017. This study concludes that the increase in the participation of renewable energies in the Chilean energy matrix since 2010 does not respond to state regulation, but rather is due to the great decrease in the costs of solar and wind energy.…”

Decarbonizing the Chilean Electric Power System: A Prospective Analysis of Alternative Carbon Emissions Policies

In this paper, we investigate potential pathways for achieving deep reductions in CO2 emissions by 2050 in the Chilean electric power system. We simulate the evolution of the power system using a long-term planning model for policy analysis that identifies investments and operation strategies to meet demand and CO2 emissions reductions at the lowest possible cost. The model considers a simplified representation of the main transmission network and representative days to simulate operations considering the variability of demand and renewable resources at different geographical locations. We perform a scenario analysis assuming different ambitious renewable energy and emission reduction targets by 2050. As observed in other studies, we show that the incremental cost of reducing CO2 emissions without carbon capture or offset alternatives increases significantly as the system approaches zero emissions. Indeed, the carbon tax is multiplied by a factor of 4 to eliminate the last Mt of CO2 emissions, i.e., from 2000 to almost 8500 USD/tCO2 in 2050. This result highlights the importance of implementing technology-neutral mechanisms that help investors identify the most cost-efficient actions to reduce CO2 emissions. Our analysis shows that Carbon Capture and Storage could permit to divide by more than two the total system cost of a 100% renewable scenario. Furthermore, it also illustrates the importance of implementing economy-wide carbon emissions policies that ensure that the incremental costs to reduce CO2 emissions are roughly similar across different sectors of the economy.
