Brazil communication base station power

As of November 2023, Brazil's transmission network consisted of approximately 184,019 km of transmission lines operating at voltage levels of 230 kV AC, 345 kV AC, 440 kV AC, 500 kV AC, ±600 kV DC, 750 kV and ±800 kV DC. Of the installed line length, 38 per cent was at 500 kV AC, followed by 38 per cent at 230 kV.

Figure 1: Installed generation capacity by fuel as of November 2023 (%) The backbone of Brazil's energy transmission is the Sistema Interligado Nacional (SIN), or National Interconnected System, encompassing four regional subsystems: South, Southeast−Midwest, North and Northeast.

Brazil has a generation capacity of over 222 GW, of which the majority or 49 per cent (110 GW) comes from hydropower, 29 per cent (63.5 GW) comes from RES such as wind and solar, and 21 per cent (46.7 GW) comes from thermal capacity. The country also has 1,990 MW of nuclear capacity, which comprises about 1 per cent of the total generation mix.

Most of Brazil's hydropower capacity is located north in the Amazon River Basin, but the load centres are mainly along the eastern coast, particularly in the south. National electricity reliability is challenged because of the long distances between generation and load centres, recurring drought conditions and deforestation.

To illustrate, América Móvil, operating in Brazil under the brand name Claro, along with Telefonica Brasil (Vivo) and TIM Brasil were each obliged to install 154 new 5G base stations in Sao Paulo alone by the end of September 2023, for a total of 462 antennas.

However, isolated systems in regions such as Amazonas, Roraima, Acre, Amapá, Rondônia and part of Pará cater to the remaining 2 per cent. Furthermore, Brazil's energy reach extends beyond its borders, with grid connections to neighbouring countries such as Uruguay, Argentina, Venezuela and Paraguay.
