October brings 26 renewable plants and 648 MW of wind in Paraíba under a new curtailment rule

Renewable expansion in 2026 is moving forward alongside the debate over generation cuts. In October, according to an ANEEL survey published by Canal Solar, all 26 plants that started operating are renewable: 23 wind farms with 648 MW, all in Paraíba, and three solar plants with 55.7 MW in Bahia, Rio de Janeiro and Minas Gerais.

These wind farms enter a system with a new rule for sharing the cuts. On 6 October 2026, ANEEL approved by 4 votes to 1 the apportionment of energy-related curtailment between wind and solar plants, closing Public Consultation 45/2019, according to Cenário Energia. Hydro plants with turbinable spillage come in after a one-year shadow operation, to be implemented within six months.

For the 648 MW in Paraíba, this changes how revenue is projected. The cut is now shared among plants by a known criterion, and the loss becomes more predictable for those who finance and those who buy the energy.

Year to date through October, 5.88 GW entered operation, and Paraíba accounts for 774 MW. With the rule defined, the likely size of the loss can go into the contract.
