Análise econômica entre os modelos autoprodutor e compensação de energia em uma indústria de papel

Abstract

An electricity end user from Santa Catarina state has a paper industry and a power station (CGH), both under CELESC distributor concession. Aiming to reduce the cost with electricity in its industry, it has demonstrated interest on making a partnership to analyze if its modality currently framed is the one who has the best economic viability.This study will compare annual costs between all modalities from the power compensation system based on the remote self-consumption defined by ANEEL’s resolution 482/2012 and energy self-production. It will also highlight what are the requirements that a consumer can be framed in: Remote self-consumption, free consumer and energy self-producer based on the current legislation showing what risks consumers can have with the short-term surplus energy exposure in the shortterm market based on the possibilities of maximum, medium and minimal PLD, besides how to find a balance point between both modalities. The Balance Point was reach at R$ 303,21 / MWh, meaning that any signed contract above the Balance Point are impracticable.
