Energy Auctions by Transmission Margin

In 2015, ONS contributed significantly to the implementation of energy auctions based on transmission system margin. To this end, ONS conducted analyzes and system studies and proposed, together with EPE, methodology and criteria for defining the generation amounts by electric area and by busbar, which could be sold at auctions, with this energy’s flow assurance at the time of delivery.

The adoption of this auction category coincided with the need to mitigate possible delays resulting from mismatch of generation andtransmission works schedules, enabling generation entrepreneurs tomore certainty in the implementation of their generating units.
