This paper analyzes the impact on market prices of the policies that have been adopted in Brazil to foster electricity from renewable energy sources (RES-E), namely wind power. In recent years the Brazilian Government implemented a series of policies that enabled a strong growth of RES-E. Recently more than 14 GW of wind and solar power were contracted. However, as most of the assets are concentrated...
Market and system operators face new challenges as more renewable energy sources are added. The driving factors in this trend are mainly associated with environmental benefits of the renewable generation and climate change mitigation, as well as the reduction of the dependency of conventional and external energy source. If integrated in large scale, the nondispatchable nature of intermittent resources...
In this paper we describe the models and the simulations that were conducted in order to access the impact of feed-in subsidized generation in the market price in Portugal in the context of the Iberian Electricity Market. In Portugal and Spain feed-in generation (namely wind power) has a large share both in terms of installed capacity and generated energy and the presence of this energy in the hourly...
With the advent of power system restructuring, there is now competition on the generation activity and the generation mix changed in many countries with the incentives to induce investments in renewables, in many cases, using volatile primary resources. Given this increase of the installed capacity in wind parks and PV stations as well as in hydro stations (as a way to address the mentioned volatility),...
Investments in new generation, specially in renewables, grew up in several countries contributing to change the generation mix. Among these new technologies, wind power became an important source in the sense that the share in installed capacity is large in countries as Germany, Denmark, Spain and Portugal namely considering the prices paid to the generated power. These subsidizing schemes are in...
