摘要: With its abundance of renewable energy potentials, not only for hydropower and bioenergy, but also wind solar, Brazil provides good prospects a carbon neutral system. The role an enhanced coupling the power, heat transport sectors in such systems is yet fully understood. This paper analyses least-cost composition operation power supply system as part Brazil. It relies on application high-resolution model REMix. Our analysis reveals that expansion solar more cost-efficient than construction additional hydroelectric plants. favoured because existing plants offer large capacity dispatchable to compensate fluctuations, thus no storage necessary. Furthermore, REMix indicates varying shares technologies well spatial distribution generation have small influence costs. implies transformation strategy can be primarily based other criteria regional development, public acceptance, environmental impact or industrial policy without major impacts
