“…The installed power of natural-gas-fired TPPs has increased in Brazil from 2,000 MW to 14,000 MW in the last two decades [12] [16]. However, it is still necessary to increase the representativeness of this power source in the coming years, and several regulatory and market barriers must be overcome [12] [17] [18].…”

This study aims to apply a methodology to analyze the regulatory obstacles for the development of thermal power plants in a country. The study uses Brazil as an application case, although mostly of the findings can be useful to other countries. It also discusses other policies and actions by the government that may contribute to the growth of natural gas-fired power plants. Using deductive and comparative research methods, the first part of this method focuses on the stage of thermoelectric power generation in Brazil. The subsequent sections present the role of the integration of gas and electricity sectors, the main obstacles to the expansion of natural-gas power generation, how the country has deal with the expansion of natural-gas power generation, as well as how other obstacles has been faced. In raising the research question, when comparing the research results of selected countries, it should be noticed the impact that the experience and lessons elsewhere have had on policies formulation on Brazil. Our conclusions pointed out that adequate policies for the natural gas-electricity Brazilian market integration make advisable the unification of electricity and natural gas agencies. We recommended developing a mathematical model to support decision-making on natural gas and electricity integration.

“…In the most relevant literature, there are no analyzes of the spatial correlation focused on the supply of bioelectricity. In Brazil, some studies have been carried out to evaluate the sector, under the spatial approach, based on other methodologies, such as Junior and Júnior [20] who evaluated the existence of spatiotemporal clusters, with the scan statistics and Junior et al [21], using concentration measures to observe supply dynamics.…”

This study was to present a methodology for analyzing the distribution and spatial-time dependence of the supply of forest bioelectricity in Brazil, from 2000 to 2019. The data for the granting of forest biomass thermoelectric plants were obtained from the National Electric Energy Agency (in Portuguese Agência Nacional de Energia Elétrica-ANEEL). It used the exploratory analysis of spatial data, and as neighborhood criteria the spatial weighting matrices of k-neighbors closest and based on distance, as well as the global and local Moran indices to detect the presence of spatial dependence. The analysis of the situation, by quartile, showed the states of the central-southern portion of Brazil as the main locations of forest thermals. I Moran_Global highlighted the decrease in spatial autocorrelation between the years 2000 and 2019, associated with the implementation of new thermoelectric plants by the large groups Fibria, Klabin and Suzano Celulose throughout the national territory. The local index (I Moran_Local ) pointed out high-powered clusters, especially in the early years, highlighting: the Bahia, Espírito Santo and Minas Gerais axis, the Paraná thermal plants and Mato Grosso do Sul thermal plants. The local index also pointed outliers, which indicated possibility of associating thermoelectric plants with other activities, such as wood production and industries in the steel and paper and cellulose segment. The knowledge of the spatial pattern of the forest bioelectricity sector presented can help new feasibility studies for the implementation in bioelectricity and/or stimulate the development of public policies, focused on cluster regions and adjacent areas, which results in the growth of forest generation.INDEX TERMS Green energy, energy economy, bioenergy, industrial ecology, forest economy, spatial economy, spatial autocorrelation, space-time change.The associate editor coordinating the review of this manuscript and approving it for publication was Zhigang Liu .

“…Market concentration can be statically analyzed in a time frame, and/or dynamically based on a time series (Kon, 1999). Some market concentration tests in the forestry sector were developed in the international scenario in the 21 st century by Coelho Junior et al (2013) for forest products, Noce et al (2007) for plywood, Coelho Junior et al (2010) and Coelho Junior et al (2018) for cellulose; Selvatti et al (2018) and Coelho Junior (2019a) for Medium Density Fiberboard (MDF); and for Brazil with Simioni et al (2017) and Coelho Junior et al (2019b;2019c) for fi rewood and charcoal, and Coelho Junior et al (2020;2021) for forest-based thermoelectric plants. In order to understand the market structure of wood pellet imports, this article evaluated the concentration of the wood pellet import market in the period from 2012 to 2018 based on concentration and inequality measures.…”

Faced with the transition in the global energy structure with the shift in consumption of fossil fuels to renewable and clean sources, there has been an increase in the demand for forest biomass for energy purposes, especially wood pellets, and imports have grown in recent years. Therefore, this study analyzed the world concentration of pellet imports from 2012 to 2018. Data on pellet imports were obtained from the Food and Agriculture Organization of the United Nations (FAO), and the following indicators were used to measure the concentration: Concentration Ratio [CR(k)], Hirschman-Herfindal Index (HHI), Theil Entropy Index (E), Gini Inequality Coefficient (G) and the Hall-Tideman Index (HTI). The results showed a growth of 16.67% p.a. of global pellet imports, from 8.76 million tons (t) in 2012 to 22.15 million tons in 2018. The CR(k) indicated very high concentration for countries and high in the subcontinents. The HHI showed a high concentration for continents and subcontinents and a moderate concentration for countries. Entropy and HTI corroborated the analyzes found in the HHI. The G pointed out strong inequality for all territorial levels and showed trends towards a reduction in inequality as of 2015. The reduction in the concentration in the final years of study is related to the expansion and technological diffusion of energy conversion of the densified biomass, which makes this fuel more affordable.
