National plan: electricity grid up to 99% clean, advancement of solar power and expansion of energy storage.

Report published in Magazine Canal Solar – Vol. 7, No. 5 October/2026

Brazil's energy transition should combine a significant expansion of renewable sources with the large-scale introduction of technologies capable of providing flexibility to the system.

This is the design that emerges from the PNE (National Energy Plan) 2055, recently approved by the MME (Ministry of Mines and Energy) and developed in conjunction with EPE (Energy Research Company).

The study projects, in the different scenarios evaluated, a share of clean energy in electricity generation of 97% to 99% in 2055, compared to 96% in 2025.

Within this transformation, solar energy is gaining ground in both centralized generation and distributed resources, while storage is ceasing to be treated as a complementary technology and is taking on a structural role in the operation of the SIN (National Interconnected System).

The plan works with three quantified scenarios — TNZ (Net Zero Transition 2050), TA (Extended Transition), and TC (Continued Transition) — which do not represent a single forecast or official government targets, but possible trajectories constructed to test alternatives, opportunities, and risks for the Brazilian energy system.

In the TNZ scenario, the most ambitious in terms of decarbonization, electricity generation reaches approximately 3.120 TWh in 2055, almost four times the current level. Wind power accounts for 36% of generation, centralized solar reaches about 27%, with 838 TWh, and hydroelectric power moves to third place, with 19% and 597 TWh.
