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.
Smart grids are expected to be at an intermediate level of development in Brazil by 2030 ( Carvalho, 2015 ). A disruptive project towards a smart grid power system has been recently proposed by a state-controlled electricity company in the country (in Portuguese, Companhia Paranaense de Energia – COPEL).
Smart metering is considered an emerging and under development technological system in Brazil. Currently, the use of smart metering is Brazil is restricted to pilot smart grid projects of specific distribution utilities. The deployment of smart meters is a fundamental step for the deployment of smart grids in Brazil.
Challenges and opportunities for a smart grid power system in Brazil are addressed. An inadequate net-metering system for DG may shift the costs from DG to non-DG users. The deployment of storage technologies is at a slow pace of growth. Regulation for electrical vehicles is still emerging.
This system was proposed by the Brazilian Electricity Regulatory Agency (ANEEL) in 2013, and it is regulated by the RN nº 547 ( ANEEL, 2013 ), although the starting point of its implementation is dated to 2015.
Summary and discussion It is well known that the global electricity sector has been witnessing a significant share of innovations together with a high increase in renewable energy, and Brazil is no exception. Decarbonization, Digitalization and Decentralization of the energy sector will be the main three key drivers of the power system evolution.

Approximately 60% of global electricity is produced via fossil fuels (British Petroleum Company, 2020), resulting in 13.2 giga tonnes (Gt) of CO2 annually (World Nuclear Association, 202. .

However, Trinidad and Tobago power generation capacity surpasses its current demand ( Inter- American Development Bank, 2015 ), which provides avenues for energy storage through low carbon H 2, MeOH and NH 3 production directly within the local downstream supply chain.
The authors greatly acknowledge the Trinidad and Tobago national electricity power produces for assisting in data collection and model verification. No funding sources were received for this study. Energ. J. ( 2018), 10.3390/en11061412
Trinidad and Tobago represents a unique case study as an industrial SID, whereby knowledge and guidance on multiple decision criteria can aid in reducing national carbon footprints.
Trinidad and Tobago is heavily dependent on its oil and gas reserves ( Fig. 3 ), petrochemical and other hydrocarbon related downstream industries ( Indar, 2019 ). Thus, the country is unique amongst SIDS and must maximise its benefit from these natural resources, in terms of energy production.
