Domestic actions contributing to the mitigation of GHG emissions from power generation in Brazil

Abstract

Continued growth and the privatisation of Brazil’s electricity system, which is largely based upon hydropower, is projected to lead to big expansion mainly of natural gas but also coal power stations with a resulting huge growth in greenhouse gases (GHG) emissions unless steps are taken to avoid this. The Brazilian National Program of Power Conservation and Efficient Use of Electrical Energy in terms of avoided GHG emissions (PROCEL), originally created in 1985, is a multi-stakeholder program coordinated by Eletrobrás aimed to reduce the waste of electrical power on both supply and demand side. Initially crippled by lack of funds, a new finance structure introduced in 1994 has greatly increased PROCEL’s impact. Here we develop scenarios that suggest that continued expansion of PROCEL’s programme, including resources that might be drawn through clean development mechanism (CDM) projects, to meet projected PROCEL targets over the next two decades could avoid approximately one-third of the GHG emissions from the Brazilian power sector. This contribution demonstrates the significant global environmental benefits of PROCEL in addition to national benefits of this innovative programme.
