FINAL STRETCH FOR 2021 SUPPLY?

OPINION

In this editorial, we update the estimates for risk and severity of energy rationings; and for risk, severity, and frequency of supply interruptions during peak hours. This update follows the same methodology as previous reports and considers the following factors: (a) storage conditions in early October; (b) probabilistic inflow and renewable production scenarios for the months of October and November; and (c) generation supply, demand, and exchange capacity between regions.

REGULATORY

In this section, we comment on (i) some controversial points in the regulation of the Capacity Reserve Auction; and (ii) the opinion of the Provisional Measure of CREG, which brings new (old) tortoises, in addition to other relevant topics.

INTERNATIONAL

INNOVATION

In this section, we comment on storage technologies and the launch of the Energy Vault (EV) company, which will apply a technology in Brazil to modulate the variability of wind production in the Northeast region.
