Bill 5,802/2025 reignited debate over Brazil’s natural gas market, setting the industry on a collision course with Petrobras and regulatory bodies.
The proposal for a compulsory gas release system in the country has become the new epicenter of discussions on energy and competitiveness in the House of Representatives. Authored by Congressman Kim Kataguiri (União-SP), the text seeks to compel dominant players to auction portions of their supply, aiming to break Petrobras’s hegemony and, consequently, lower the input cost for the national industry.
The clash pits large consumers—who suffer from high tariffs—against the main oil and gas sector players. While the industry demands drastic measures to boost competition, technical agencies and the state company argue that the market already shows signs of easing and that legislative interventions could create legal uncertainty.
The industry’s view: competitiveness and access to the molecule
For large consumers, the urgency is clear. Energy‑intensive sectors such as glass and construction argue that supply decentralization is the only path to survival and factory expansion. Entities like Abrace and Abividro use the PPSA auctions as a success model to push prices down.
Industrial representatives maintain that market opening must go beyond bureaucratic hurdles, ensuring that the molecule reaches factories at competitive prices. The thesis is that Petrobras’s dominance acts as a barrier to the development of essential production chains.
“Forced deconcentration does not automatically guarantee a tariff reduction for the end consumer; there is a real risk of creating new oligopolies in intermediate marketing that would capture margins without passing the benefit to the productive sector.”
Technical Opposition: ANP, IBP, and MDIC
On the other side, the ANP (National Agency of Petroleum, Natural Gas and Biofuels) and the IBP (Brazilian Institute of Petroleum and Gas) argue that the New Gas Legal Framework has already produced positive results. The agency points out that market concentration fell from nearly 100% to about 55%, indicating a natural opening that respects regional specificities.
The MDIC (Ministry of Development, Industry, Trade and Services) shared this skepticism, warning that state intervention may be ineffective. The ministry fears that the transfer of volumes from Petrobras to intermediary marketers will not reach the end consumer, resulting only in a shift of concentration.
Petrobras Reaffirms Its Role in the Market
Petrobras, the main focus of the measure, maintains that its firm market share has dropped to 46% by the third quarter of 2026. The state-owned company points to robust investments, such as the new flow route of the Rota 3 pipeline in the Santos Basin, as more effective in lowering the price of the molecule than compulsory sale mechanisms.
For the company, fulfilling previous commitments, such as the TCC of Cade, combined with constant oversight by the ANP, is the balanced path for the sector. The outlook for the coming months remains uncertain, with the need to reconcile the pressure for lower industrial costs with the stability of contracts that sustain private investment flows in the country.
