Brazil's renewable power surge masked by rising grid instability risk

A global report ranks Brazil seventh worldwide for risk of energy‑grid instability despite the country generating 77.38% of its electricity from renewable sources, the highest share among major economies. The study attributes the vulnerability to weaknesses in transmission and distribution, with average outage durations of 6.75 hours and an average frequency of 3.75 interruptions, affecting roughly 16% of the population that is considered demographically vulnerable.

At the same time, higher prices in Brazil’s free‑market electricity sector in 2024 have erased about R$9.3 billion in potential gains to the nation’s energy‑competitiveness. Average market prices rose to R$438.5 per megawatt‑hour after a previous decline, increasing operating costs for businesses and limiting the competitive advantage of Brazil’s clean‑energy generation. Analysts note that regulatory reforms could improve cost predictability and competition, but the most significant tariff reductions are not expected until 2026‑2027.
