(1) | Cemig GT requested from Aneel a review of the amounts paid for the RGR Contribution in prior years, due to the basis of calculation used at the time for calculation of the charge. Cemig GT recognized the right to recover the amount paid in excess, to be offset against RGR payable, only after the conclusion, in 2016, of a judgment by Aneel, as per Aneel Technical Note 162/2016, which accepted Cemig GT’s claim. As per decision by Aneel, management of the RGR became the responsibility of Eletrobras.
