(1) The balance payable to the CCEE refers basically to the hydrological risk of quotas for Itaipu. The increase in the balance payable, due to the hydrological risk, and also of the CCEARs, is associated with the adverse hydrological context.
(2) The charges payable by distribution and generation agents for use of the facilities that are components of the national grid. The amounts to be paid are set by an Aneel Resolution.
(3) In 2017 the Company reported higher expenses of energy due to the higher cost of supply in the wholesale market, arising from the low level of reservoirs, which resulted in lower output of power by the hydroelectric plants.
