Around 14 GW of irregular distributed solar threatens grid security in Brazil, warns TÜV Rheinland
Unauthorized distributed-generation expansions in Brazil could add up to 14 GW of unregistered capacity, complicating grid planning and operation, TÜV Rheinland warns. The expansion of PV systems up to 5 MW without proper design reviews or approvals also raises electrical safety risks and compliance concerns.
El Niño could drive PV generation curtailment to 40% in Brazil in 2026
A strong El Niño in late 2026 could push renewable generation curtailment in Brazil to 25%, with solar PV curtailment potentially reaching 40%. Additional thermal dispatch could further increase PV curtailment to 47%, raising financial risks for renewable projects.
