Concentration and Clusters of Black Liquor Thermoelectric Plants in Brazil

Bioelectricity generation from sugarcane is significant across Brazil and is related to regional market structure characteristics where the mills are located. To understand the distribution and conjuncture of this sector, this study analyzes the pattern of location, concentration and clustering of the bioelectricity supply from sugarcane bagasse in Brazil, for 2017 and 2022. The data were obtained from the Brazilian National Electric Energy Agency, and the methodology was based on concentration indices and scan statistics. The results showed that the Southeast region presented the most thermoelectric power plants and installed capacity. The Southeast and Midwest regions were highly concentrated in terms of quantity and sugarcane bioelectricity installed capacity. Five clusters were identified for the number of power plants in 2017; for 2022, there were eight clusters. Regarding installed potential, there were 14 clusters in 2017 and 23 clusters in 2022, all statistically significant. The existence of clusters provides information on the competitive advantages in the national market, which can drive new investments in more densified areas or in the neighborhood. Identification of the location and concentration pattern showed that facilities in the state of São Paulo and the Northeast coast were responsible for the most important share of supply. These results indicate to investors the impact of electricity generation on the sector and the most relevant location for installing new thermoelectric plants.

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.
