We study the difference between urban and rural elasticities for electricity residential consumption in Portugal. Our sample covers the period from 1989 to 2010 and consists of five independent surveys. We adopt the pseudo-panel methodology creating 350 cohorts based on the size of the household, the type of location (rural or urban), the region, and the income quintile. Our results indicate that...
The different energy sources, their costs and impacts on the environment determine the electricity production process. Energy planning must solve the existence of uncertainty through the diversification of power generation technologies portfolio. The European Union energy and environmental policy has been mainly based on promoting the security of supply, efficiency, energy savings and the promotion...
Sustainable development and environmental protection are key concepts in the European energy policy. The Europe 2020 Strategy establishes the necessity of reducing environmental pressure and resource consumption to increase sustainable development in the EU. In this context, the aim of this paper is to develop an Environmental and Resource Pressure Aggregated Index that considers these two dimensions...
There is no consensus on the method to set transmission tariffs for natural gas. The entry–exit system is widely used in European markets because it is cost reflective, it allows the network users to separately book capacity for entry and exit points, beyond its pro-competitiveness characteristics. Some authors, however, defend the adoption of the postage stamp (where a single tariff is charged regardless...
In the last few decades, electricity markets have undergone extensive reforms. A process of liberalizing electricity markets has been implemented by several countries, reducing the incumbents' market power. Thus, generation and retail are open to competition, while transmission and distribution remain regulated. Furthermore, the need to comply with the targets set by the Kyoto Protocol has boosted...
Portfolio Theory can result in a valid and contrasted methodology for evaluating real assets and electricity production portfolios within the construct of energy planning. It results in a more complete alternative to the least-cost perspective. In the proposed model the production costs of all technologies are considered, including the different components of externalities (not only CO 2 costs)...
