Selection of energy projects: the effect of decision making on the relationship between energy source and sales price

Lincoln Sposito, Fernando Ribeiro Serra


Objective of the study: This study aims to identify the effect of decision making on the relationship between the energy source and the establishment of the sales price in electricity auctions for the selection of auction projects.

Methodology / approach: Statistical tests were performed on an auction base that concentrates the majority of energy auctions held in the Brazilian market. The relationships between the establishment of the sales price and energy sources and the moderating effect of power, hours of operation, and period of use on this main relationship were evaluated.

Originality / Relevance: The formation of a portfolio of electric energy projects through the prior selection of energy auction projects, via a multi-criteria decision-making process, is a valid strategy for companies in the sector.

Main results: It was identified that there is awareness of the sales price based on the energy source and relevant criteria for decision making, such as capacity and implementation period.

Theoretical-methodological contributions: This study contributes to a process of analysis and preparation of the secondary database of electricity auctions made available by the Electric Energy Commercialization Chamber (CCEE). The theoretical contribution is made by enabling the use of multi-criteria processes for decision making.

Contributions to Society / management: Managers can use the methodology applied in this study to create a portfolio of projects with less risk for decision making.
