Descripción
The generation of electric energy by the sugarcane sector stands
much below its potential. Using five case studies with São Paulo plants,
this article aims to identify the obstacles to the expansion of the electric
energy commercialization by the sugarcane sector. High costs associated to
the commercialization of electric energy - in commercialization of excesses,
and in the acquisition for proper consumption – are the most reasonable
explanation for the self-sufficiency in the production of electric power by
the sugarcane sector, an allied energy to the small generation of excesses
of energy for commercialization. Out of the five plants studied, three
plants that commercialize energy excesses make it as part of a strategy of
anticipation of the future need of self-sufficiency. Having associated costs
for sale of excesses of electric energy, they do not have incentives to the
use of technologies of higher energy efficiency. The public policy directed
to the expansion of energy excesses must turn toward the reduction of the
costs associated to the commercialization thereof. Particularly interesting
it would be to increase the volume of free consumers and to support the
commercialization between these and the co-generators of energy.
