“…As Romeiro makes clear, since 2005 [41], 18 auctions have been held in Brazil using the Benefit-Cost Ratio (BCR (Only in the context of energy auctions, BCR is measured in R$/MWh and in this paper we use it in the same meaning as Reference Price)) mechanism to select product availability, contracting an average of more than 22 GW. However, due to the considerable challenges in acquiring an environmental license for hydropower plants, only 22% of the contracted energy came from hydropower, with 16% from wind and 62% from thermoelectric sources.…”

Stakeholder Perspectives on Energy Auctions: A Case Study in Roraima, Brazil

2023

Energy auctions are commonly used to contract energy projects and are extensively studied from the regulator’s perspective. However, analyzing auctions from the stakeholders’ perspective is critical to determine the impact of regulatory details on the bidder’s revenues. In this study, we analyze a public energy auction in Roraima, a Brazilian state with a significant energy deficit and no grid connection, where many projects were successful in the non-intermittent Power Product category, typically unfavorable for biomass. Using Linear Programming to maximize bidders’ revenues, we examine the regulatory formulas that contributed to the success of these projects and compare the optimization results to actual revenues. Our analysis shows that certain regulatory elements can benefit stakeholders by allowing them to make unconventional project design decisions. In addition, we identify a possible loophole in the formula that can have the opposite effect of the regulator’s intent in the renewable Power Product category. Our findings can help bidders increase profits through optimization and regulators to change formulas if objectives are not met. This study brings the often-overlooked perspective of stakeholders to energy auctions, adding to the literature on this topic.
