The deficit cost is used as exogenous parameter in the chain of models for planning the operation and expansion of a hydrothermal system as part of the total cost of operation. The results show a cointegration relationship between GDP and electricity consumption; therefore, there is a long-term equilibrium relationship between GDP and electricity consumption. This relationship is used to estimate the curve of deficit marginal cost. The possible short-term imbalance can be mitigated using the vector error correction model (VEC). Keywords: Energy deficit; Cointegration; Rationing; Energy planning JEL Classifications: Q40; Q43; Q47; Q48

Considering that Brazil has continental-scale dimensions and diversified geography, an alternative that allows smoothing the intermittency in solar PV power generation is needed. The novelty of this study lies in the proposal to allocate the production of PV solar energy between the interconnected regions of the country efficiently, forming an optimal portfolio with the highest productivity and the least intermittency. Thus, the regional allocation process for solar generation is formulated through an optimization problem with two objective functions: to increase the country's productivity and simultaneously control the variability of the supply of solar energy. This study concluded that the current planning models for the expansion in Brazil (both centralized and distributed generation) do not consider the variability of incident solar ...

Thus, the regional allocation process for solar generation is formulated through an optimization problem with two objective functions: to increase the country’s productivity and simultaneously control the variability of the supply of solar energy. This study concludes that the current models of planning for the expansion of Brazil do not consider the variability of solar irradiation incident in the five regions of Brazil.

Since first-generation (1G) ethanol uses the sugars of sugarcane, an integrated 1G–2G production would enable the production of more ethanol from the same amount of sugarcane without leading to increased use of arable land. The ethanol production process is complex, involving different high-energy consumption operations such as evaporation and distillation. The economic competitiveness of this process depends heavily on the amount of thermal and electrical energy produced using sugarcane straw and bagasse as input. Thus, the objective of this study was to use the mean-variance methodology to determine the optimal allocation of residual sugarcane biomass between 2G ethanol and bioelectricity productions, with simultaneous objectives of maximizing the return and minimizing the risk fo...

The best competitive strategy for Brazilian distributors is cost leadership aimed at encouraging the loyalty of potentially free clients, generators and technology developers who're able to freely circulate between the Regulated Contracting Environment and the Free Contracting Environment.

The first is to present a prompt method to estimate the necessary time period spent to obtain an environmental permit for pipelines and other oil and gas industrial units, including one category for small units and another for medium and large units, taking into consideration previous experiences in obtaining environmental permits for Petrobras in Brazil.
