BRASILIA, Aug 12 (Reuters) - Brazil power regulator Aneel rejected an appeal from electricity distributor AES Corp's Brazil unit Eletropaulo Metropolitana SA on Tuesday, maintaining an order to return 626 million reais ($274.6 million) to customers.
The payment was ordered to compensate for what Aneel sees as an improper accounting for 246 kilometers of cable investments, which impacted the size of a previous government-controlled tariff adjustment.
