Ma. Almeida et al., The potential for electricity conservation and peak load reduction in the residential sector of Brazil, ENERGY, 26(4), 2001, pp. 413-429
This paper summarizes the methodological approach and the results of a stud
y aimed at assessing the potential for electricity conservation and peak lo
ad reduction in the Brazilian residential sector. The study splits the resi
dential sector into 15 subsectors, considering five different geographical
regions and three household income classes. Technical, economic and market
potentials are determined both for electrical energy conservation and peak
load reduction in the period from 2000 to 2020. The main findings show an e
lectricity conservation technical potential for the residential sector of 2
8%, an economic potential of 14% and market potentials of 12% and 8%. The c
orresponding results found for the peak load reduction in 2020 were a techn
ical potential of 21%, an economic potential of 4% and market potentials of
3% and 2%, with the large reduction in percentage savings for peak demand
in the economic and market scenarios explained in particular by the omissio
n of solar water heating from those scenarios. Finally, carbon dioxide emis
sion reductions associated with the electricity conservation potentials and
peak load reductions are also estimated. (C) 2001 Elsevier Science Ltd. Al
