Summary/Abstract

The electricity sector planning in Brazil aims to promote a reliable and safe supply of electricity to society. There are risks associated with planning out these projects in regard to environmental licensing (particularly with Transmission Systems). This paper presents a conceptual model for a solid analysis of the electricity sector by providing a regulatory and procedural assessment; it aims to connect issues with environmental licenses to those ventures. The results show that delays and uncertainties are related to the concession of energy transmission projects, which have not conducted any previous studies on the possible environmental impacts and have not applied the Environmental Impact Assessment as an instrument for decision-making. In order to minimize these uncertainties, studies on environmental planning should be conducted in the early stages of the project, prior to concession, as the venture is granted only once the projects have been demonstrated to be environmental viable.

Towards a smart grid power system in Brazil: Challenges and opportunities / Dranka, Géremi Gilson

Summary/Abstract

The prospects for a smart power system have been widely discussed in the global electricity sector. Decarbonization, Digitalization and Decentralization are considered the main key drivers for this power system transition and Brazil is no exception to this universal trend. A search of the literature revealed few studies which attempt to address the main challenges and opportunities towards a smart grid power system in Brazil. This paper provides an up-to-date assessment of the present and potential capabilities of existing and future technologies, regulations and policies and attempts to identify how these elements are interrelated. Our findings add to a growing body of evidence suggesting that policies for Distributed Generation (DG), Demand-Side Management (DSM) and new tariff schemes are on a path of accelerated deployment in the country. The deployment of storage technologies, however, is at a slow pace of growth. We highlight the need to further develop new business models to address the various decentralized energy technologies and services that are emerging in the sector. The current net-metering system is considered a key issue to be addressed as this regulatory structure may shift the costs from DG to non-DG users.
