The GT (working group) created by the Federal Government to discuss strategies that can minimize the impacts of curtailment in Brazil, especially in the Northeast region, will meet this Thursday (13) to begin discussions on the topic.
The meeting aims to coordinate actions, carry out diagnostics and suggest regulatory and operational measures that can minimize the impacts of cuts in renewable energy generation. The group was created at the CMSE (Electric Sector Monitoring Committee) meeting on March 6.
Government creates working group to minimize curtailment in solar and wind power plants
The working group is made up of bodies such as the MME (Ministry of Mines and Energy), the ANEEL (National Electric Energy Agency), EPE (Energy Research Company), ONS (National Electric System Operator) and CCEE (Electric Energy Trading Chamber).
In addition to this meeting, a second technical meeting is also scheduled for March 31, with a focus on discussing the governance of computational risk assessment models. The criteria, procedures and deadlines for applying these measures will be announced soon.
Damage caused by curtailment
The term curtailment refers to the forced reduction of energy generation by order of the ONS – which states that the measure is adopted to guarantee the safety and stability of the electrical grid when the instantaneous supply exceeds the consumption of the without (National Interconnected System).
For months, companies in the energy sector have been warning the Federal Government about the need for urgent measures, since the cut in production from wind and solar plants has become a problem that has caused financial losses for many companies.
A study by consultancy Volt Robotics, for example, revealed that more than 1,4 solar and wind power plants suffered cuts in energy generation as determined by the ONS in 2024.
Financial losses exceed R$1,6 billion, with more than 14,6 TWh of average energy cut. In total, more than 400 thousand hours of generation were interrupted, with the Northeast being the most impacted region, accumulating 330 thousand hours.
