Project Presented on November 11, 2025 Promises to Reorganize Prices, Reduce Concentration, and Create New Rules for the Sector
The federal deputy Kim Kataguiri (União-SP) presented on November 11, 2025 the Bill No. 5802/2025, which creates the Managing Committee for Promotion of Competition in the Natural Gas Market (GEGÁS), according to documents sent to the Chamber and disclosed by agencies such as ANP, MME, and EPE. Thus, the project aims to increase competition, decentralize decisions, and strengthen oversight of the market. Additionally, the proposal is based on technical analyses conducted by sector institutions throughout 2024 and 2025.
Technical Investigation Points to the Need for Market Reorganization
Studies presented to Congress demonstrated that the market remains highly concentrated, even after the implementation of the New Gas Law in 2021, according to data released by the National Agency of Petroleum, Natural Gas and Biofuels (ANP). Thus, GEGÁS will act as the responsible body to certify reference prices, define auction products, and monitor competitiveness, which could significantly alter the current structure.
Furthermore, the committee may integrate representatives from ANP, the Ministry of Mines and Energy (MME), the Ministry of Development, Industry, Commerce, and Services (MDIC), the Energy Research Company (EPE), the Administrative Council for Economic Defense (Cade), and associations from the natural gas chain. Thus, the initiative aims to ensure technical, collegial, and transparent decisions.

Proposed Changes for the Dominant Agent’s Sales
The bill stipulates that the dominant agent must sell part of its gas to third parties in public auctions, which creates conditions to reduce market concentration. However, the proposal excludes LNG (Liquefied Natural Gas) import contracts, short-term operations below 30 days, and biomethane contracts, according to criteria discussed in technical meetings held in 2024.
On the other hand, gas from the dominant agent’s own production may be traded freely, without the obligation to sell in auctions. According to Kataguiri, “the proposal is based on technical analyses developed by sector entities”, emphasizing that structural changes are essential to reduce the current level of concentration.
Expected Economic and Regulatory Impacts on the Sector
The proposed changes could stimulate competition, attract new suppliers, and increase transparency in auctions, according to assessments presented by energy consultants in meetings of the MME between April and September of 2025. Additionally, agencies such as EPE and Cade stated in technical notes released in 2024 that decentralization is a decisive step towards modernizing the Brazilian natural gas market.
The sector also registers increased demand since 2022, according to official surveys from EPE, making the discussion even more relevant.
Technical Discussions Signal Next Steps in the Processing
The text now goes for analysis in the thematic committees of the Chamber and is expected to drive the energy sector throughout 2026, according to planned legislative schedules. Experts point out that Bill 5802/2025 could transform rules, reorganize prices, and create a more competitive environment for buyers and suppliers.
Thus, the creation of GEGÁS emerges as a possible regulatory turning point for the country, at a time when the energy sector seeks stability, transparency, and sustainable growth.
Will the natural gas market finally reach the level of competition deemed essential by regulatory agencies?
