Ongoing Regulatory Issues
 Discussions with ANEEL regarding hourly unavailability penalties vs 60-month moving average
unavailability criteria (ADOMP);
 Discussions with ANEEL regarding pass-through criteria for energy acquired;
 Possibility to increase firm energy of Pecém I and Itaqui by 10MW/each, reflecting contractual capacity of
360MW/each vs 350 MW registered in the energy auctions). New firm energy numbers should be
calculated by MME;
 Request filed at ANEEL so that appropriate treatment is given to Pecém II as the MPX cannot be held
liable for delays in transmission systems for which it is not responsible.
