The planning of the operation is updated on an annual cycle, with the participation of associated agents. It consists of the planning of the energy operation, which assesses the conditions of energy supply for the BIPS considering a five-year horizon - January of the current year to December of the fifth year ahead - and the planning of electric operation, which evaluates the operating conditions of the power grid to the horizon of 16 months, from January of this year to April of the second year ahead. Daily and weekly schedules are presented ahead, produced with severe involvement of the groups in which electrical and energy aspects intertwine increasingly, to the extent that the analysis horizon is shortened.
