Brazil's reliance on hydropower makes the country highly susceptible to droughts. Deforestation and climate change are also affecting water availability, further stressing hydropower resources. In fact, a severe drought in 2021 caused energy shortages and an increased reliance on more expensive and polluting thermoelectric plants.
In such context, Brazil has promoted the use of distributed energized resources (DER) to create a more balanced, resilient, and sustainable energy system. This aims to make the country less dependent on hydropower and enhance overall energy security. A diversified energy mix with a significant share of DER is expected to prevent power shortages and reduce the need for thermoelectric plants.
