It is common to come across news about ANEEL auctions, also called energy auctions. Do you know what they mean?
In short, auctions are mechanisms through which concessionaires, permit holders, and authorized public electricity distribution service providers ensure market supply.
According to the Ministry of Mines and Energy, in the Regulated Contracting Environment, selling agents (generators, traders, and self-producers) and distributors establish contracts through bidding processes.
Auctions, therefore, are nothing more than bidding processes conducted to contract the electricity needed to meet existing demand.
There are several types of auctions:
- Sales Auction
- Alternative Sources Auction
- Surplus Auction
- Structuring Auction
- Reserve Energy Auction
- New Energy Auction
- Existing Energy Auction
- Purchase Auction
- Adjustment Auction
In these, the winners and distribution agents sign contracts to meet the future demand of energy distributors. This is how the concession of new plants is carried out, for example.
Without auctions, the electricity sector would face difficulties in balancing energy supply and consumption, increasing the risks of energy shortages and rationing.
By setting contract prices, auctions also determine the type of energy source used, which affects the value of tariffs paid by consumers.
Therefore, the next time you hear about an auction, pay attention: auctions are important for the functioning and energy sustainability of the country.
