Production curtailment imposed by the Brazilian grid operator

Voltalia (Euronext Paris, ISIN code: FR0011995588), an international player in renewable energy, announces that the Brazilian transmission system operator is currently imposing a pronounced curtailment in certain parts of the network, which would have a strong impact on Voltalia's 2024 EBITDA if it were to be extended over the coming months and if it is not financially compensated. Voltalia is carrying out a series of actions to reduce the duration of this curtailment and to be financially compensated.

For a transmission system operator, curtailment consists in limiting the transmission, for a given period, of all or part of the electricity production potential of a power plant, in order to maintain the stability of the transmission network.

In Brazil, like other major global power grids, curtailment has been rare in previous decades. However, following a blackout in August 2023, the Brazilian operator began capping an unusually high part of production to minimize the risks of instability. As the network proved to be stable, curtailment gradually decreased to become marginal at the end of 2023.

Noting the resumption of a pronounced level of curtailment, Voltalia met several times with the Brazilian transmission network operator. Voltalia's production curtailment volume in the northeast of the grid could be high for a period that could last several months, in particular due to the delay in the construction of new transmission lines to strengthen the grid in the northeast of the country.

Voltalia, within a collective of electricity producers and through professional associations, as well as directly, is currently carrying out a series of initiatives in Brazil:

  • Several litigation actions, already initiated in 2023, are underway before the federal and local courts, with the law providing for financial compensation applying in particular to Voltalia's power plants1.

  • Constructive discussions are being held in parallel, with the network operator and the public authorities in order to accelerate at least a part of the financial compensation and to reduce the duration of the current capping.

Voltalia is confident about the effectiveness of these steps, but it is difficult to establish a precise figure for the financial effect of the curtailment on the 2024 EBITDA. Voltalia estimates that, if the scenario communicated by the network operator were confirmed, if Voltalia was not financially compensated and if the average EUR/BRL exchange rate for the second half of the year was around 6, its 2024 EBITDA would be cut by around 40 million euros.
