This article describes the electricity consumption in Brazilian residences between 1985 and 2013 through linear regressions. The explanatory variables considered were the number of households, effective consumption of families as a proxy for family income, and electricity tariff for households. To deal with the power generation crisis of 2001 we have introduced a dummy variable in the form of a step function. With such explanatory variables, we were able to account for the reduction of household electricity consumption caused by the policies conducted in 2001 and their permanent consequences. The regression presented coefficient of determination of 0.9892, and the several statistic tests conducted assured the existence of long-term relation between the electricity consumption in residences and the explanatory variables. The obtained elasticities for the household consumption of electricity with respect to number of residences, family income and residential tariff of electricity were 1.534±0.095, 0.189±0.049, and −0.230±0.060, respectively. These results allowed understanding the evolution over time of the household consumption of electricity in Brazil. They suggest that the electric sector in Brazil should pursue an active policy to manage demand of residential electricity using tariffs as a means to control it. 相似文献

In many countries, distribution grid tariffs are being reformed to adapt to the new realities of an electricity system with distributed energy resources. In Europe, legislative proposals have been made to harmonize these reforms across country borders. Many stakeholders have argued that distribution tariffs are a local affair, while the European institutions argued that there can be spillovers to other countries, which could justify a more harmonized approach. In this paper, we quantify these spillovers in a simplified numerical example to give insight and an order of magnitude. We look at different scenarios, and find that the spillovers can be both negative and positive. To be able to quantify these effects, we developed a long-run market equilibrium model that captures the wholesale market effects of distribution grid tariffs. The problem is formulated as a non-cooperative game involving consumers, generating companies and distribution system operators in a stylized electricity market. 相似文献

In the presence of learning spillovers related to renewable energy technologies, an optimal strategy to mitigate climate change should complement an emissions tax by a subsidy for renewables. This article addresses the question how such subsidy should be designed. It is shown that the widely-used approach of a revenue-neutral fixed feed-in tariff can yield an optimal outcome under restrictive conditions only. It has to be adapted continuously as the electricity price changes. Moreover, funding the tariff by a surcharge on the electricity price has important implications for the design of the emission tax. The optimal tax rate has to be below the Pigovian level, differentiated across fossil fuels and adapted over time as the patterns of technological development change. These requirements may pose a formidable challenge for practical decision-making. However, it is important to point out that the eventual choices made with respect to the design and funding of a feed-in tariff have to be based on a careful and more comprehensive policy assessment, including, inter alia, economic effects beyond the electricity sector and existing institutional constraints. 相似文献
