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.

Landing stores, Atlas Cove, Heard Island with Rogers Head in background Photo: Alan Campbell-Drury Due to the extreme isolation of Heard Island and McDonald Islands (HIMI), together with the persistently severe weather and sea conditions, human activities in the region have been, and remain, limited.
It is the biggest contribution to ocean conservation anywhere on the planet this year. The Heard and McDonald Islands marine reserve will quadruple in size, an increase of almost 310,000 km2 – an area larger than Italy – and will provide greater protections for an environment unlike anywhere else in the world.
The islands are a territory (Territory of Heard Island and McDonald Islands) of Australia administered from Hobart by the Australian Antarctic Division of the Australian Department of Climate Change, Energy, the Environment and Water.
The group's overall land area is 372 km 2 (144 sq mi) and it has 101.9 km (63 mi) of coastline. Discovered in the mid-19th century, the islands lie on the Kerguelen Plateau in the Indian Ocean and have been an Australian territory since 1947. Heard Island and McDonald Islands contain Australia's only two active volcanoes.
Since the first landing on Heard Island in 1855, there have been only approximately 240 shore-based visits to the island, and only two landings on McDonald Island (in 1971 and 1980).
Heard Island - 80% ice-covered, bleak and mountainous, dominated by a large massif (Big Ben) and an active volcano (Mawson Peak); McDonald Islands - small and rocky fish Mawson Peak, an active volcano, is on Heard Island

Solar energy is widely available in Armenia due to its geographical position and is considered a developing industry. In 2022 less than 2% of Armenia’s electricity was generated by solar power. The use of solar energy in Armenia is gradually increasing. In 2019, the European Union announced plans to assist Armenia towards developing its solar power capacity. The initiat. . According to the , Armenia has an average of about 1720 (kWh) solar energy flow per square meter of horizontal surface annually and ha. . As of April 2019 ten 1 MW strong solar stations are installed. Solar and wind stations account for less than 1% of total installed electricity generation capacities. In April 2019 it was announced that German company Das En. In this article, we address the current state of solar energy in Armenia, potential investments and industrial developments in the solar energy sector. [pdf]
