Electronic auction in the price registration system and its impacts on the efficiency of public procurement for the PNAE in the state of Tocantins

Abstract

This study analyzed the impacts of electronic reverse auction procedures, implemented through the Price Registration System (SRP), on the efficiency of public procurement related to the National School Feeding Program (PNAE) in the State of Tocantins, Brazil. The research examined three bidding procedures conducted in the fiscal years 2024, 2025, and 2026 by School Support Associations, based on data extracted from the National Public Procurement Portal (PNCP). The theoretical framework articulated the regulatory framework of public procurement—particularly Federal Law No. 14,133/2021, Law No. 11,947/2009, and Law No. 15,226/2025—with empirical studies on procurement efficiency, electronic reverse auctions, the Price Registration System, and public policies for school feeding. A mixed-methods approach was adopted, combining qualitative and quantitative techniques, including documentary analysis and comparative statistical analysis of estimated and awarded values, percentage reductions, and number of bidders. The results indicated that increased competitiveness was directly associated with greater cost savings, demonstrating a correlation between the number of participants and price reduction rates. It was concluded that the electronic reverse auction, when combined with the Price Registration System, constitutes a relevant instrument for promoting administrative efficiency, transparency, and the strengthening of public school feeding policies.
